Introduction: The Tool That Stops You Getting Ripped Off

I want to tell you something that took me years of building financial calculators to fully appreciate: the scrap gold market is one of the most information-asymmetric transactions that ordinary people face. On one side of the counter sits a professional gold dealer who calculates scrap gold value dozens of times per day. On the other side sits someone who inherited a jewelry box, found an old chain, or needs quick cash — someone who almost never knows what their gold is actually worth.

That information gap costs people hundreds, sometimes thousands of dollars per transaction.

I started building scrap gold calculators after a close friend sold a collection of old jewelry at a pawn shop for PKR 45,000. When I ran the pieces through my own calculator tool — the same logic I use across a range of precision tools, from a one rep max calculator for strength athletes to a passport photo generator for document processing — the scrap melt value came out to PKR 118,000. She had received less than 40% of the gold's actual intrinsic value.

That experience became the motivation behind building the most precise, user-friendly scrap gold calculator I could create — one that handles every unit used in every major gold market: karats for purity, tolas for South Asian transactions, grams for international jewelry retail, and troy ounces for global bullion pricing. A tool that works for a jeweler in Lahore, a pawn shop owner in London, a gold investor in Dubai, and a seller in New York equally well.

This guide is the complete manual for that tool. By the time you finish reading, you will know exactly how to calculate the scrap gold value of any piece, in any unit, at any karat level — and you'll never walk into a gold transaction uninformed again.

What Is Scrap Gold and Why Does It Have Value?

Scrap gold is any gold-containing item whose value lies primarily in its gold content rather than its form, craftsmanship, or collectibility. This includes:

Old or broken jewelry (rings, chains, earrings, bangles, bracelets)
Dental gold (crowns, bridges, inlays)
Gold coins sold for melt value rather than numismatic premium
Industrial gold components (connectors, contacts, circuit board elements)
Gold-filled items (where sufficient gold content justifies refining)
Unwanted or unfashionable jewelry where melt value exceeds resale value

The value of scrap gold is derived entirely from its melt value — the theoretical worth of the pure gold content if the item were melted and refined back to fine gold. This calculation is the core function of a scrap gold calculator.

Gold retains its value across all forms because it is chemically inert — it does not corrode, oxidize, or degrade. A gold bracelet from the 1970s has the same gold content today as when it was made. The spot price may have changed dramatically (it has — gold has risen from around $200/ozt in the 1970s to over $2,600/ozt in 2026), but the gold itself is unchanged. That permanence is what makes scrap gold trading possible and profitable.

The Scrap Gold Calculator Formula — Complete Technical Breakdown

The scrap gold calculation is built on one formula applied with precision across varying inputs. Here it is in full:

Scrap Gold Value = Weight in Grams × Purity Decimal × Spot Price per Gram

Where:

Weight in Grams = your item's weight converted to grams from whatever unit you're using
Purity Decimal = the gold purity fraction (e.g., 0.75 for 18K, 0.9167 for 22K)
Spot Price per Gram = current gold spot price per troy ounce ÷ 31.1035

Let me show you this as a complete, production-ready calculation engine:

    karat:           karat || 'custom',

    // Value outputs
    spotPerGram:     +spotPerGram.toFixed(4),

    // Percentage outputs

    calculatedAt:    new Date().toISOString()
  };
}

This is the complete engine. Notice that I include dealer offer ranges as a standard output — because melt value without context is only half the answer. Knowing your melt value AND knowing what percentage of it different buyer types typically offer transforms a calculation into a negotiation tool.

Karat Guide — Complete Purity Reference for Scrap Gold Calculation

Understanding karats is the most important prerequisite for accurate scrap gold calculation. Karat (abbreviated K or kt) measures the proportion of pure gold in an alloy, expressed as parts per 24.

Complete Karat-to-Purity Conversion Table

Karat	Purity %	Decimal	Millesimal Fineness	Common Markets
24K	99.99%	0.9999	999	Bullion, investment bars, Chinese jewelry
22K	91.67%	0.9167	916/917	India, Pakistan, Middle East, UK Sovereigns
21K	87.50%	0.8750	875	Gulf countries (UAE, Saudi Arabia, Kuwait)
20K	83.33%	0.8333	833	Rare, some Middle Eastern regions
18K	75.00%	0.7500	750	Europe, USA, international fine jewelry
16K	66.67%	0.6667	667	Rare, some antique pieces

8K	33.33%	0.3333	333	Germany, some European antiques

Reading Gold Hallmarks for Scrap Calculation

Hallmarks are the stamped purity marks on gold items. Knowing how to read them is critical for scrap gold calculation because the purity you input directly determines the calculated value.

Numeric hallmarks (millesimal fineness):

999 or 9999 → 24K gold
916 or 917 → 22K gold
875 → 21K gold
750 → 18K gold
585 or 583 → 14K gold
417 → 10K gold
375 → 9K gold
333 → 8K gold

Letter hallmarks (karat marking):

24K, 22K, 18K, 14K, 10K, 9K → direct karat indication
GF → Gold Filled (NOT solid gold — very different melt value calculation)
GP or GEP → Gold Plated (negligible melt value)
GV or V → Gold Vermeil (gold-plated silver, minimal gold melt value)
HGE → Heavy Gold Electroplate (plated, not solid)
RGP → Rolled Gold Plate (thin layer, not solid)

Critical warning: GF (gold-filled) and GP (gold-plated) items have drastically lower scrap gold value than solid gold. A 14K gold-filled bracelet weighing 15 grams has approximately 5% of the melt value of a solid 14K bracelet of the same weight (gold-filled is only ~5% gold by weight by US FTC standards). Never input these into a solid gold scrap calculator without adjusting for actual gold content.

Weight Units Explained — Tola, Gram, Ounce, and More

One of the defining features of a professional scrap gold calculator is its ability to handle all regional weight units accurately. I've dealt with support requests from users in Pakistan confused by troy vs. avoirdupois ounces, Indian dealers working in tolas, Thai jewelers using baht, and Vietnamese traders using chi. Here is the complete reference:

Troy Ounce vs. Avoirdupois Ounce — The Critical Distinction

This is the single most expensive unit confusion in the scrap gold market.

Unit	Grams	Used For
Troy Ounce (ozt)	31.1035g	ALL precious metals pricing globally
Avoirdupois Ounce (oz)	28.3495g	General US/UK commercial weight
Difference	2.754g	9.7% error if confused

Gold spot price is always quoted per troy ounce. If you divide spot price by 28.35 instead of 31.10, your per-gram price is inflated by 9.7% — meaning your scrap value calculation is overstated by nearly 10%. On a $1,000 transaction, that's a $100 error.

Every professional scrap gold calculator must use 31.1035 grams per troy ounce. No exceptions.

Tola — The South Asian Standard

The tola is the dominant gold weight unit in Pakistan, India, Bangladesh, Nepal, and much of the Middle East. It is deeply embedded in the regional gold trade:

1 tola = 11.6638 grams (precise value)
1 tola ≈ 3/8 troy ounce (approximate)
10 tolas ≈ 116.638 grams ≈ 3.75 troy ounces

Many online calculators use the rounded 11.66g instead of the precise 11.6638g. The difference: 0.0038g per tola. On a 100-tola gold lot (a common commercial quantity in South Asian markets), that's a 0.38g discrepancy — worth approximately PKR 2,000–3,000 at 2026 prices. For commercial operations processing multiple lots daily, this error compounds significantly.

My scrap gold calculators always use 11.6638g for tola. It matters.

Complete Weight Unit Conversion Reference

Unit	Exact Grams	Primarily Used In	Notes
Gram (g)	1.000000	Universal	Global standard for jewelry
Kilogram (kg)	1000.000000	Large lots	Refineries, institutional
Troy Ounce (ozt)	31.103500	Global metals	ALWAYS use for spot price
Pennyweight (dwt)	1.555170	North America	Jewelry industry standard
Tola	11.663800	S. Asia, Middle East	Pakistan, India, UAE
Baht	15.244000	Thailand	Thai gold trade
Chi	3.750000	Vietnam	Vietnamese jewelry trade
Mace	3.779936	Hong Kong, China	Chinese jewelry trade
Avoirdupois Oz	28.349500	General US/UK	NOT for gold pricing

Scrap Gold Calculation by Weight Unit — Worked Examples

Let me walk through complete scrap gold calculations for each major weight unit, using a realistic 2026 gold spot price of $2,700 per troy ounce ($86.80 per gram).

Calculation in Grams

Item: 18K gold bracelet, 14.5 grams

Spot per gram = $2,700 ÷ 31.1035 = $86.80/g
Purity (18K) = 0.75
Pure gold weight = 14.5 × 0.75 = 10.875g
Melt value = 10.875 × $86.80 = $943.95 USD

Calculation in Tolas (Pakistan/India)

Item: 22K gold bangle, 3 tolas

Weight in grams = 3 × 11.6638 = 34.9914g
Purity (22K) = 0.9167
Pure gold weight = 34.9914 × 0.9167 = 32.085g
Spot per gram = $86.80/g
Melt value = 32.085 × $86.80 = $2,784.98 USD
In PKR (at ~280 PKR/USD) = PKR 780,000 (approx.)

Calculation in Troy Ounces

Item: 24K gold bar, 0.5 troy ounces

Weight in grams = 0.5 × 31.1035 = 15.5518g
Purity (24K) = 0.9999
Pure gold weight = 15.5518 × 0.9999 = 15.5502g
Spot per gram = $86.80/g
Melt value = 15.5502 × $86.80 = $1,349.76 USD

Calculation in Pennyweights (North American Jewelry)

Item: 14K gold ring, 4.5 pennyweights

Weight in grams = 4.5 × 1.55517 = 6.998g
Purity (14K) = 0.5833
Pure gold weight = 6.998 × 0.5833 = 4.082g
Spot per gram = $86.80/g
Melt value = 4.082 × $86.80 = $354.32 USD

Calculation in Baht (Thailand)

Item: 96.5% pure Thai gold chain (Thai standard), 2 baht

Weight in grams = 2 × 15.244 = 30.488g
Purity (Thai 96.5%) = 0.965
Pure gold weight = 30.488 × 0.965 = 29.421g
Spot per gram = $86.80/g
Melt value = 29.421 × $86.80 = $2,553.74 USD

Note: Thai gold (called "Baht gold") is a unique standard at 96.5% purity — between 23K and 24K. My calculator includes Thai gold as a dedicated purity option, not just a karat-based selection.

Scrap Gold Value in Local Currencies — PKR, INR, AED, GBP, EUR

For international users, melt value in USD must be converted to local currency for the number to be practically useful. Here's how currency conversion works in a professional scrap gold calculator — and why it matters more in some markets than others.

Currency Conversion Formula

Local Currency Value = Melt Value USD × Current FX Rate

Example: Melt value = $500 USD
At 280 PKR/USD → PKR 140,000
At 83 INR/USD → INR 41,500
At 3.67 AED/USD → AED 1,835
At 0.79 GBP/USD → GBP 395
At 0.92 EUR/USD → EUR 460

Why Currency Matters Especially for PKR and INR Users

For gold investors and sellers in Pakistan and India, the local currency value of scrap gold is doubly interesting:

Double appreciation effect: When gold rises in USD terms AND when PKR weakens against USD (as it has persistently over recent years), scrap gold value in PKR appreciates much faster than the USD spot price movement alone.

Example:

2020: Gold at $1,800/ozt, USD/PKR = 165 → 1 ozt gold = PKR 297,000
2026: Gold at $2,700/ozt, USD/PKR = 280 → 1 ozt gold = PKR 756,000
Increase in PKR terms: +155% vs. +50% in USD terms

A scrap gold calculator that shows both USD and PKR values simultaneously lets South Asian users see the full picture of their gold's appreciation.

Live Currency Rates in the Calculator

Professional scrap gold calculators integrate live FX rate APIs alongside gold spot price APIs:

async function getLivePriceData(targetCurrency = 'PKR') {
  // Fetch gold spot price
  const goldResponse = await fetch('https://www.goldapi.io/api/XAU/USD', {
    headers: { 'x-access-token': process.env.GOLD_API_KEY }
  });
  const goldData = await goldResponse.json();
  const spotUSD = goldData.price;

  // Fetch live FX rate
  const fxResponse = await fetch(
    `https://api.exchangerate-api.com/v4/latest/USD`
  );
  const fxData = await fxResponse.json();
  const fxRate = fxData.rates[targetCurrency];

  return {
    spotUSD,
    spotLocal: spotUSD * fxRate,
    fxRate,
    currency: targetCurrency,
    spotPerGramUSD: spotUSD / 31.1035,
    spotPerGramLocal: (spotUSD / 31.1035) * fxRate,
    lastUpdated: new Date().toISOString()
  };
}

With this setup, the calculator auto-populates both spot price and exchange rate on load — the user only needs to enter weight and select karat.

Scrap Gold Lot Calculator — Multi-Item Batch Valuation

In professional scrap gold operations — pawn shops, gold dealers, estate buyers, refineries — valuing multiple items simultaneously is the daily reality. A single-item calculator is insufficient. Here's how batch scrap gold calculation works:

Multi-Item Lot Calculation

function calculateScrapGoldLot(items, spotPriceUSD) {
  const spotPerGram = spotPriceUSD / 31.1035;
  let totalMeltValue = 0;
  let totalWeightGrams = 0;
  let totalPureGoldGrams = 0;

  const itemResults = items.map((item, index) => {
    const weightGrams = item.weight * WEIGHT_UNITS[item.unit];
    const purity = item.customPurity
      ? item.customPurity / 100
      : KARAT_PURITY[item.karat];

    const pureGoldGrams = weightGrams * purity;
    const meltValue = pureGoldGrams * spotPerGram;

    totalWeightGrams += weightGrams;
    totalPureGoldGrams += pureGoldGrams;
    totalMeltValue += meltValue;

    return {
      item: index + 1,
      description: item.description || `Item ${index + 1}`,
      weightGrams: +weightGrams.toFixed(4),
      karat: item.karat || 'custom',
      purityPercent: +(purity * 100).toFixed(2),
      pureGoldGrams: +pureGoldGrams.toFixed(4),
      meltValueUSD: +meltValue.toFixed(2)
    };
  });

  // Effective karat of the entire lot
  const effectivePurity = totalPureGoldGrams / totalWeightGrams;
  const effectiveKarat = (effectivePurity * 24).toFixed(2);

  return {
    items: itemResults,
    totalWeightGrams: +totalWeightGrams.toFixed(4),
    totalPureGoldGrams: +totalPureGoldGrams.toFixed(4),
    totalMeltValueUSD: +totalMeltValue.toFixed(2),
    effectivePurity: +(effectivePurity * 100).toFixed(3),
    effectiveKarat: +effectiveKarat,
    spotUsed: spotPriceUSD
  };
}

Real Lot Calculation Example

A pawn shop receives the following items from one customer:

Item	Weight	Unit	Karat	Pure Gold	Melt Value
Gold ring	4.2g	gram	14K	2.450g	$212.66
Bangle	2.5 tola	tola	22K	26.810g	$2,327.59
Chain	8.7g	gram	18K	6.525g	$566.37
Earrings	3.1g	gram	10K	1.292g	$112.17
Ring	1.8g	gram	24K	1.800g	$156.24
TOTAL				38.877g	$3,375.03

At spot = $86.80/g:

Total lot melt value: $3,375.03 USD
Effective lot purity: 71.4% = approx. 17.1K blended
Fair dealer offer (80% of melt): $2,700
Pawn shop lowball (40% of melt): $1,350

The difference between knowing your melt value and not knowing it: $1,350 vs. $2,700. That's the value of the scrap gold calculator.

Scrap Gold Purity Testing — Before You Calculate

The most accurate scrap gold calculator in the world is useless if you input the wrong karat. Purity verification is the prerequisite to calculation. Here are the methods, from least to most precise:

Method 1: Hallmark Reading (Free, Immediate)

Look for the stamp. This is always the first step. Under a jeweler's loupe or 10x magnifier, stamps are readable on almost all post-1900 jewelry. See the hallmark guide in the previous section for interpretation.

Reliability: High for modern jewelry from regulated markets (UK, EU, US). Lower for vintage pieces, some Asian jewelry where stamps may be approximate, or pieces where the stamp is worn.

Method 2: Acid Test Kit ($20–$50)

Acid test kits contain bottles of nitric acid solutions at concentrations corresponding to different karat levels (8K, 10K, 14K, 18K, 22K). A small scratch of the gold is touched to a test stone, acid applied, and the reaction color indicates purity.

Reliability: Good for go/no-go testing. Can distinguish broad karat categories (10K vs 18K) but less reliable at distinguishing close karats (14K vs 18K). Slightly destructive (micro-scratch required). Error range ±1–2K.

Best for: Quick field verification by pawn shop buyers, individual sellers confirming unlabeled pieces.

Method 3: Electronic Gold Tester ($200–$500)

Electronic testers use conductivity measurement to estimate gold purity. Non-destructive and fast (2–5 seconds per reading).

Reliability: Moderate. Good for bulk screening but affected by alloy composition, plating, and surface condition. Error range ±1–3K. Not suitable for precision commercial transactions.

Best for: High-volume scrap buyers doing rapid preliminary screening before XRF verification.

Method 4: XRF (X-Ray Fluorescence) Analysis ($15,000–$40,000 equipment, or $10–$30 per test at service)

XRF shoots X-rays at the gold sample and analyzes the fluorescent energy spectrum to determine elemental composition. It identifies every metal present (gold, silver, copper, zinc, nickel, etc.) to three decimal places.

Reliability: The gold standard (appropriately) for scrap purity testing. Error range ±0.1%. Non-destructive. Results in 10–30 seconds.

Best for: Any commercial scrap gold operation, refinery intake, or situation where the transaction value makes testing cost-effective (which is most situations over $500).

Method 5: Fire Assay (Definitive, Destructive)

The most precise purity testing method in existence. A small sample is melted, treated with acid, and the resulting pure gold is weighed precisely. Accurate to 0.01% purity.

Best for: Refinery verification of large lots, dispute resolution, assay certification of gold bars.

Scrap Gold Buyer Types — Who Pays What Percentage of Melt Value

Understanding buyer behavior is as important as the calculation itself. Every scrap gold buyer discounts from melt value — the question is by how much. Here is my field-verified guide:

Pawn Shops

Typical offer: 35–55% of melt value

Pawn shops are not gold specialists. They buy gold alongside electronics, instruments, and general merchandise. Their gold buyers often use simplified (sometimes incorrect) calculators, and their business model requires high margins to cover risk, operational costs, and inventory financing.

When to use them: Only as a last resort for immediate cash. Never as a benchmark for gold's value.

Negotiation tip: Show them your melt value calculation. Even if they can't match it, demonstrating knowledge of the melt value often improves their offer by 10–15%.

Cash-for-Gold Services

Typical offer: 45–65% of melt value

Dedicated gold buying operations (storefronts and mail-in services) do better than pawn shops but still maintain substantial margins. Mail-in services often quote 50–60% initially with the ability to negotiate up to 65–70%.

Warning: Mailed gold is difficult to retrieve if you're unsatisfied with the offer. Always use insured, tracked shipping and confirm the return policy before sending.

Local Gold Dealers / Jewelers

Typical offer: 70–85% of melt value

Specialized gold dealers and jewelers who buy scrap for resale or refinement typically offer better rates. They have lower overhead than retail pawn shops and more accurate pricing tools.

Best approach: Get quotes from 2–3 local dealers. Show the melt value calculation to each. Competition between buyers drives prices up.

Online Gold Refiners

Typical offer: 80–95% of melt value

Online precious metal refiners (companies that actually smelt and refine gold) offer the highest percentages because they have the lowest overhead and the most efficient processing. Examples include established refiners in the UK, USA, and UAE that accept mail-in scrap lots.

Best for: Larger lots (50g+ of pure gold equivalent) where the refining economics favor the refiner paying high percentages.

Peer-to-Peer Sales

Potential return: 90–100% of melt value (or above, if sold as jewelry)

Selling directly to another individual — via local gold groups, marketplace platforms, or community networks — eliminates dealer margin entirely. You receive melt value or above.

Risks: Requires trust verification, payment security, and may attract buyers attempting to pay less than melt for "jewelry premium" deductions.

Summary Table: Scrap Gold Buyer Comparison

Buyer Type	% of Melt Value	Best For	Avoid When

Scrap Gold Prices Today — Market Context for 2026

To use a scrap gold calculator effectively, understanding the current market context is essential. Here's where things stand as we move through 2026:

Gold has maintained historically elevated prices, trading above $2,600/ozt through late 2025 and into 2026, supported by:

Central bank demand: Global central banks — particularly China's People's Bank, Reserve Bank of India, and several Eastern European central banks — have been net buyers of gold for multiple consecutive years. This institutional demand provides a structural floor under prices.

Geopolitical risk premium: Ongoing global tensions have sustained gold's safe-haven premium. Historically, geopolitical uncertainty adds $50–$150/ozt to gold's price above what macro-economic models would predict.

Inflation dynamics: While inflation has moderated from 2022–2023 peaks in most developed economies, gold's role as a long-term purchasing power preserver continues to attract investment demand.

Dollar correlation: Gold is priced in USD, so USD weakness typically boosts gold prices in USD terms. The dollar's long-term trajectory remains a key driver of gold price.

Practical implication for scrap gold calculation: At $2,700/ozt ($86.80/gram), scrap gold values are at or near historical highs. This is an excellent time to sell scrap gold you've been holding. A piece worth $400 at $1,800/ozt spot is now worth $600 at $2,700/ozt — a 50% increase in scrap value with no change to the physical gold.

Always use a live spot price in your calculator. Today's calculation can differ from yesterday's by $10–$30 per gram in volatile markets.

Special Scrap Gold Categories — Dental Gold, Electronics, Gold-Filled

Not all scrap gold is jewelry. Here's how to handle special categories in the scrap gold calculator:

Dental Gold

Dental alloys contain gold in concentrations ranging from approximately 40% (low-gold dental alloys) to 80%+ (high-gold casting alloys). They also typically contain palladium, silver, copper, and other metals.

How to calculate:

Without assay: Use estimated purity of 50–60% (10K–14K equivalent) as a conservative estimate
With assay certificate: Use the stated gold percentage directly as the custom purity input
XRF testing at a dental gold refiner gives precise results and the best prices

Where to sell dental gold: Specialist dental gold refiners offer 80–90% of the gold melt value on verified lots. General pawn shops typically offer far less because they can't accurately assess dental alloy purity.

Electronics Scrap (E-waste Gold)

Circuit boards, CPU processors, gold-plated connectors, and other electronics contain trace quantities of gold — far less per gram of material than jewelry, but the economics can work at scale.

Important: A basic scrap gold calculator is NOT the right tool for e-waste gold calculation. The gold content in electronics is measured in parts per million (PPM) or milligrams per unit, not as a percentage of total weight. E-waste requires specialized recovery calculators and professional assaying.

Rough reference: 1 ton of smartphones contains approximately 300–400 grams of recoverable gold. 1 ton of standard motherboards contains approximately 150–250 grams. These require industrial-scale processing.

Gold-Filled Items

Gold-filled (GF) jewelry has a mechanically bonded layer of gold alloy that by US FTC standards must constitute at least 1/20th (5%) of the item's total weight. The karat of the gold layer is typically 12K or 14K.

Calculation for 12K gold-filled, 20g item:

Gold content = 20g × 5% = 1g of 12K alloy
Pure gold weight = 1g × 0.50 = 0.5g pure gold
Melt value at $86.80/g = $43.40 USD

Compare to solid 12K: 20g × 0.50 × $86.80 = $868 USD

The difference is stark. Gold-filled melt value is roughly 1/20th of the equivalent solid gold piece. Many buyers incorrectly calculate gold-filled items as if they were solid gold — either through error or deliberately. Know the distinction.

Gold Vermeil

Gold vermeil (pronounced "ver-may") is sterling silver (92.5% silver) plated with gold to a minimum thickness of 2.5 microns. The gold content is minimal — typically 0.1–0.5% of total weight.

Scrap calculation: Calculate the silver melt value using the silver spot price and 92.5% purity, plus the negligible gold layer. The silver content is the primary scrap value driver for vermeil pieces.

Frequently Asked Questions (FAQs)

What is a scrap gold calculator?

A scrap gold calculator computes the intrinsic melt value of gold-containing items based on three inputs: weight (in grams, tolas, troy ounces, or other units), karat purity (9K, 10K, 14K, 18K, 22K, 24K, etc.), and the current live gold spot price per troy ounce. It gives you the theoretical value of the pure gold content — your baseline for any gold selling transaction.

How do I calculate scrap gold value in tola?

Multiply the tola weight by 11.6638 to convert to grams. Then multiply by the karat purity decimal (e.g., 0.9167 for 22K). Then multiply by the current spot price per gram (spot per troy oz ÷ 31.1035). For 22K gold at 2 tolas with $2,700/ozt spot: (2 × 11.6638) × 0.9167 × ($2,700 ÷ 31.1035) = 23.328 × 0.9167 × $86.80 = $1,857.09 USD.

What percentage of melt value do scrap gold buyers pay?

It varies widely by buyer type: pawn shops pay 35–55% of melt value; cash-for-gold services pay 45–65%; local gold dealers pay 70–85%; online refiners pay 80–95%; peer-to-peer sales can reach 90–100%. Always calculate melt value first so you can evaluate any offer against the theoretical maximum.

What karat is most common in scrap gold?

It varies by region. In the USA, 14K and 10K dominate jewelry scrap. In the UK, 9K is most common. In Pakistan, India, and the Middle East, 22K and 21K are predominant. In China, 24K (999 gold) jewelry is the standard. A comprehensive scrap gold calculator handles all karat levels.

How do I verify the karat of scrap gold without a hallmark?

Without a visible hallmark, use an acid test kit for quick field verification (±1–2K accuracy), an electronic gold tester for non-destructive screening (±1–3K accuracy), or XRF analysis at a jewelry store or refinery for precise results (±0.1%). Never rely on appearance alone — gold plating, gold-filled construction, and solid gold look similar but have dramatically different melt values.

Is gold-filled worth calculating as scrap gold?

Gold-filled items have some scrap value but far less than solid gold. By US FTC standards, gold-filled must be at least 5% gold by weight. A 20-gram 14K gold-filled item contains only 1 gram of 14K alloy = 0.583 grams of pure gold ≈ $50 in melt value, vs. $868 for solid 14K of the same weight. Always identify gold-filled (GF stamp) before calculating.

Does scrap gold value change daily?

Yes, continuously. Gold spot price moves every second during trading hours on COMEX (New York) and LBMA (London). A price movement of $50/ozt changes the melt value of a 10-gram 18K piece by approximately $12. For commercial transactions, always use a live spot price from the day of the transaction — never a price from yesterday or earlier.

What is the best way to sell scrap gold?

For maximum return: (1) calculate your melt value using a live spot price, (2) get quotes from at least 3 buyers — include at least one online refiner, (3) compare all offers as a percentage of your calculated melt value, (4) choose the highest. For lots over $500 in melt value, online refiners typically offer the best rates. For amounts under $200, a local gold dealer may be most practical after accounting for shipping and insurance costs.

What is the difference between scrap gold and bullion gold?

Scrap gold refers to gold items (typically jewelry, dental gold, or industrial components) sold for their metal content. Bullion gold refers to gold bars and coins produced specifically as investment vehicles with certified purity and weight. Bullion trades at spot price or a small premium above it; scrap gold is purchased by dealers at a discount below melt value (because they need to cover refining and operational costs).

How much is 1 tola of 22K gold worth in 2026?

At $2,700/ozt spot (approximate 2026 level): 1 tola = 11.6638g, 22K purity = 0.9167, spot per gram = $86.80. Melt value = 11.6638 × 0.9167 × $86.80 = $928.38 USD. In PKR at 280 PKR/USD = approximately PKR 259,946. This changes daily with spot price movements — always use a live calculator for current values.

Conclusion: Your Scrap Gold Is Worth More Than They're Offering

After years of building scrap gold calculators and watching how the market treats uninformed sellers, I have one core message: know your melt value before you walk into any gold transaction.

The scrap gold calculator is the tool that eliminates information asymmetry. It takes the same calculation that every professional gold buyer runs before making you an offer — the same math they use to determine how much margin they can capture from you — and puts it in your hands, for free, before the negotiation begins.

A pawn shop offering you 40% of melt value on a $1,000 piece is offering you $400. That same piece at a reputable gold dealer gets you $800. The difference is $400. The calculation takes 30 seconds. That is the most valuable 30 seconds in any gold transaction.

Calculate your melt value. Know your karat. Use the right weight unit for your region — tola, gram, or troy ounce. Verify your purity. Then compare offers against your calculated baseline, not against your intuition.

The gold in your drawer has real, calculable value. Make sure you receive it.
