Everyday Calculators
Scrap Gold Calculator
Estimate gross melt value and an optional payout scenario from user-entered assumptions.
Enter the values and review the result.
Enter one item and exclude stones and clearly non-gold components where possible.
Troy ounces and ordinary avoirdupois ounces are different units.
The displayed fineness value, in parts per thousand, is used in the calculation.
No price is supplied or updated automatically.
This code is a display label only. No currency conversion is performed.
A user-entered scenario from 0% through 100%, not a predicted buyer or refiner offer.
Enter the required gold-bearing material weight and your own gold price to see gross melt value.
Results and breakdowns will appear here after a valid calculation.
Calculation assumptions
- *Enter one item and only the estimated weight of its gold-bearing solid material. Exclude stones and clearly non-gold components where possible.
- *The calculator does not determine actual recoverable refinery weight or verify a hallmark, stamp, or assay.
- *Results are unsuitable for gold-plated, gold-filled, rolled-gold, vermeil, or mixed-material items unless you already know the actual solid-gold content.
- *Any payout percentage is a user-entered scenario, not a prediction or representation of all possible deductions.
- *The selected currency code is a display label only; no foreign-exchange conversion is performed.
Gross melt value and payout are different
Gross melt value is arithmetic based on gold-bearing weight, displayed fineness, and the price you enter. Estimated payout is optional and applies only the percentage you enter; it is not a prediction of an actual commercial offer.
Illustrative example, not a current market quote: 10 grams at 18K (750) contains 7.5 grams of pure-gold equivalent. At an entered price of USD 70 per gram, gross melt value is USD 525.00. An entered 80% payout scenario produces USD 420.00.
What the payout scenario does not model
Actual deductions may involve testing, refining, recoverable weight, non-gold content, transaction costs, and commercial margins. The optional percentage combines none of those automatically and does not represent a buyer, refiner, or market standard.
Material, fineness, and unit limits
Use this single-item workflow only when you know or can estimate the solid gold-bearing weight. It cannot value plated, filled, rolled-gold, vermeil, or mixed-material items from total item weight.
- A troy ounce is 31.1034768 grams; an ordinary avoirdupois ounce is 28.349523125 grams.
- Twenty pennyweight equals one troy ounce.
- The exact displayed fineness, not a theoretical karat fraction, is used.
- The currency code labels the arithmetic only and does not invoke an exchange rate.
Quick answers
What this calculator answers
- Gross result: Calculates gross melt value from weight, fineness, and the user-entered price.
- Optional scenario: Calculates estimated payout only when you enter a payout percentage.
- Limit: The payout scenario is not an actual buyer offer, refinery settlement, or professional appraisal.

Frequently Asked Questions
Common questions about Scrap Gold Calculator and how to read the result.
Is the payout percentage required?
No. Leave it blank to calculate gross melt value without claiming a payout estimate.
Does 100% payout equal gross melt value?
Yes, mathematically. It remains a user-entered scenario rather than a buyer or refiner quote.
Does this calculator supply a gold price?
No. You must enter the price and choose whether it is per gram or per troy ounce.
Can I enter the total weight of jewellery with stones?
Not reliably. Exclude stones and clearly non-gold components where possible and use only estimated gold-bearing solid-material weight.
Does changing the currency code convert the result?
No. The currency code is a display label only. The numeric inputs are not converted.
Is this a professional appraisal or cash offer?
No. It is an educational gross melt calculation with an optional user-entered payout scenario.
