Precious Metals Value Calculator - Gold to Rhodium | 1Dollars

Free Precious Metals Value Calculator

Calculate combined gold, silver, platinum, palladium and rhodium value from each metal's weight, purity and entered price. Review allocation and estimated payout in one currency.

Gold, Silver and PGM Portfolio Value

Enter weight, purity and a matching current price for one or more metals. Prices are not fetched automatically; use one currency across every active row.

Gold
Use verified fineness or assay, converted to percent.
Silver
For example, 925 fineness equals 92.5%.
Platinum
Palladium
Rhodium
Use actual contained solid-metal weight; plating is not the item's full weight.

Currency and payout adjustments

Convert external quotes first; do not mix currencies.
Keep 100% for intrinsic value before dealer deductions.

No live spot price, exchange rate, assay, embedded-metal recovery, tax or guaranteed dealer offer is supplied. Use verified weights and purities plus same-currency prices for comparable dates and market bases.

Reviewed on 16 July 2026 using LBMA precious-metal benchmark information, NIST Handbook 44 and Handbook 130 (2026), and established precious-metal weight and purity formulas.

This precious metals value calculator combines gold, silver, platinum, palladium and rhodium without assuming they share the same price, purity or weight unit. Each active metal is converted to fine grams before its value is added.

Quick answer: enter weight, purity and a same-currency pure-metal price for each metal you own. The calculator shows individual value, portfolio allocation, combined intrinsic value and estimated net payout.

Precious Metals Value Formulas

Fine metal weight = gross metal weight × purity percentage
Metal intrinsic value = fine weight × entered pure-metal price per normalized unit
Combined intrinsic value = gold + silver + platinum + palladium + rhodium values
Estimated net payout = combined intrinsic value × dealer payout % − fixed fees

Value allocation is each metal's intrinsic value divided by the combined intrinsic value. Weighted purity is total fine-metal weight divided by total gross metal weight.

How to Use the Precious Metal Calculator

  1. Enter positive weight for every metal you want to include.
  2. Select each metal's weight unit independently.
  3. Enter verified purity as a percentage.
  4. Add the matching pure-metal price and price unit for the same date.
  5. Use one currency for every active price.
  6. Leave unused metal rows at zero weight with a blank price.
  7. Keep dealer payout at 100% to calculate intrinsic value before deductions.
  8. Add only separately stated refining, transaction and other fixed fees.

Entered Prices Instead of Automatic Live Spot Prices

LBMA describes global benchmark prices for gold, silver, platinum and palladium delivered in London. Benchmark data, retail bullion quotes, exchange-traded prices and local dealer offers can differ in timing, currency, location and licensing terms.

This page does not fetch, store or redistribute a benchmark. Enter the price you are permitted to use and record its timestamp, currency, unit and market basis. For rhodium, use a current quote from the relevant refiner, dealer or contract rather than assuming it shares another PGM benchmark.

Use comparable prices: all active prices must use the selected currency and a reasonably consistent valuation time. Convert external currencies before entering them.

Purity, Fineness and Karat Conversion

Purity percentage represents the mass share of the selected precious metal in the entered gross metal weight. Fineness expressed in parts per thousand can be divided by 10 to obtain percent.

  • 999.9 fineness = 99.99%
  • 999 fineness = 99.9%
  • 950 fineness = 95%
  • 925 fineness = 92.5%
  • 22K gold = 22 ÷ 24 × 100 = about 91.6667%
  • 18K gold = 18 ÷ 24 × 100 = 75%

Hallmarks and markings are useful clues but are not a substitute for an assay when the transaction requires verified content.

Troy Ounce vs Regular Ounce

Precious-metal market prices are commonly quoted per troy ounce, while ordinary shipping and household scales may use avoirdupois ounces. They are different units:

  • 1 troy ounce = 31.1034768 grams
  • 1 regular avoirdupois ounce = 28.349523125 grams
  • 1 pennyweight = 1.55517384 grams
  • 1 grain = 0.06479891 gram
  • 1 kilogram = 1,000 grams

The calculator normalizes weight and price units independently through grams, preventing a grams-versus-troy-ounce mismatch.

Worked Multi-Metal Value Example

Assume a same-date formula example with 10 g of 91.6% gold at USD 75 per fine gram, 100 g of 92.5% silver at USD 0.95 per fine gram, and 5 g of 95% platinum at USD 32 per fine gram.

  • Gold: 10 g × 91.6% × USD 75 = USD 687.00
  • Silver: 100 g × 92.5% × USD 0.95 = USD 87.88
  • Platinum: 5 g × 95% × USD 32 = USD 152.00
  • Combined intrinsic value: USD 926.88
  • At 96% payout less USD 15 fixed fees: estimated net payout = USD 874.80

The example uses invented prices to demonstrate the formula. It is not a current market quote.

Understanding Metal Allocation

Allocation is based on value, not weight. A small quantity of a higher-priced metal can represent a large share of portfolio value. The output reports each active metal's fine weight and percentage of combined intrinsic value.

Allocation calculated from current value is different from investment cost allocation. Purchase premiums, taxes, fabrication charges and prior acquisition prices are not included unless reflected in separate analysis.

Intrinsic Value vs Dealer Payout

Intrinsic metal valueFine metal weight multiplied by the entered pure-metal price. It excludes collectible, brand, fabrication and gemstone value.
Estimated net payoutIntrinsic value after the entered dealer payout percentage and fixed refining or transaction fees.

A dealer may use assay results, minimum lots, treatment charges, payable-metal percentages, bid/ask spreads and settlement delays. Enter only terms that match the actual offer to avoid double deductions.

Jewelry, Plating and Catalytic Converter Limits

Use only the gross metal weight to which the stated purity applies. Remove or separately measure stones, springs, clasps, cores and other components when a qualified process allows it.

Do not enter the full weight of rhodium-plated jewelry as rhodium. Likewise, do not enter an entire catalytic converter's weight as platinum, palladium or rhodium. Catalyst valuation requires specialist sampling, assay, recovery and buyer terms.

Safety: do not cut, grind, burn, chemically process or dismantle jewelry, catalysts or industrial material for this calculator. Unknown, regulated or hazardous material requires qualified handling.

How to Compare Precious Metal Offers

  • Compare prices from the same date, currency and unit.
  • Confirm whether the quote is bid, spot reference, retail or payable price.
  • Use verified gross weight and purity for each metal.
  • Separate percentage deductions from fixed fees.
  • Ask how assay variance, stones, base metals and minimum lots are treated.
  • Compare net settlement and payment timing, not the headline percentage alone.

Frequently Asked Questions

How do I calculate combined precious metals value?
Convert each metal's weight to fine weight using its purity, multiply by its matching pure-metal price, then add the gold, silver, platinum, palladium and rhodium values.
Does the calculator provide live precious metal prices?
No. Enter current prices you are permitted to use, with the same currency and a comparable valuation time.
Can each metal use a different weight unit?
Yes. Each metal has an independent weight unit and price unit. Values are normalized through grams.
Can I mix USD and INR prices?
No. Convert every active price into the single selected currency before calculating the combined total.
How is precious metal purity entered?
Enter percent purity. Divide parts-per-thousand fineness by 10; for karat gold, divide karat by 24 and multiply by 100.
Is a troy ounce the same as a regular ounce?
No. A troy ounce is 31.1034768 g, while a regular avoirdupois ounce is 28.349523125 g.
Can I value rhodium-plated jewelry using the full item weight?
No. Plating is only a surface layer. Use actual contained rhodium weight from reliable records or specialist analysis.
Can this tool value a catalytic converter?
Only if verified contained weights and matching prices are already known. Do not treat the entire converter weight as PGM content; specialist assay and buyer terms are normally required.
What does dealer payout percentage mean?
It is the share of calculated intrinsic value payable before fixed fees. Keep it at 100% when you only want intrinsic value.
Is the calculated precious metals value guaranteed?
No. Assay, price timing, currency conversion, spreads, fees, taxes, product premiums and buyer terms can change actual settlement.
