About the Silver & Gold Investment Calculator

Silver is priced per troy ounce, and the number that matters for an investor is not today's spot price on its own but how today's value compares with what you actually paid. This calculator multiplies the ounces you hold by today's price per ounce, compares that with your cost, and shows your profit or loss in dollars and as a percentage of cost. The method is the same for gold, platinum or any metal quoted per ounce, so you can use it for any bullion position.

How to Use the Silver & Gold Investment Calculator

  1. 1

    Enter the troy ounces you hold (grams ÷ 31.1035; a 1 kg bar is 32.1507 oz).

  2. 2

    Enter the all-in price you paid per ounce: total paid, including premium and fees, ÷ ounces.

  3. 3

    Enter today's price per ounce — ideally the dealer's buy-back price — then press Calculate.

How Silver (and Gold) Investment Value Is Calculated

Precious metals are priced per troy ounce, so the calculator multiplies the ounces you hold by a price per ounce twice: once with what you paid (your cost basis) and once with today's price (current value). The difference is your profit or loss, and dividing it by the cost gives the return on cost. The same method works for gold, platinum or any metal quoted per ounce.

Use all-in prices. Your purchase price per ounce should include dealer premium, shipping and fees (total paid ÷ ounces). For a realistic current value, use the price a dealer would pay you (the bid or buy-back price), not the spot price or the dealer's selling price.

Because the return is measured on cost, it does not depend on how many ounces you hold: 1 oz or 100 oz bought at $22 and valued at $29 both return 31.82%.

Priced-Out Silver and Gold Positions

  1. 1100 oz of silver coins bought at an all-in $22.00/oz; a dealer now offers $29.00/oz.

    Cost = 100 × 22.00 = $2,200.00; Value = 100 × 29.00 = $2,900.00; P/L = 2,900 − 2,200

    Current Value = $2,900.00 · Profit = $700.00 · Return = 31.82%

    A 31.82% gain on cost. Whether that is good depends on how long you held it — see "Reading the result" below.

  2. 2A 1 kg bar (1,000 ÷ 31.1034768 = 32.1507 troy oz) bought at $31.50/oz; today's buy-back price is $28.40/oz.

    Cost = 32.1507 × 31.50 = $1,012.75; Value = 32.1507 × 28.40 = $913.08; P/L = 913.08 − 1,012.75

    Current Value = $913.08 · Loss = −$99.67 · Return = −9.84%

    The bar is under water by about 10%; it is back to break-even when dealers pay $31.50/oz again. Enter 32.1507 in the Quantity (oz) field — the calculator works in troy ounces.

What the Gain Figure Covers

Return on cost is not an annual return. A 31.82% gain over six months and over ten years are very different results; convert it to a yearly rate with the CAGR Calculator to compare with other investments.

Real versus nominal: if prices in general rose while you held the metal, part of the gain only offsets inflation. Check what your cost is worth in today's money with the Inflation Calculator.

Your break-even buy-back price per ounce equals your all-in purchase price per ounce.

What a Spot-Price Estimate Leaves Out

  • Troy ounces, one currencyPrices are per troy ounce and in a single currency; no currency conversion is applied.
  • Selling costsDealer spread, shipping and assay costs are only included if you enter a buy-back price rather than spot.
  • Holding costs and taxesStorage, insurance and taxes are not included; results are pre-tax.
  • Several purchasesCalculate each lot separately and add the results, or enter total ounces with the weighted average price (total paid ÷ total ounces).
  • Not tax or investment adviceIn the US, physical precious metals are generally taxed as collectibles — the IRS states a maximum 28% rate on collectibles gains. Rules differ in the UK, Canada and Australia.

Where Bullion Estimates Go Wrong

  • Grams or kitchen ouncesEntering grams or avoirdupois ounces in the Quantity (oz) field overstates the result: grams by about 31×, avoirdupois ounces by about 10% (10 oz on a kitchen scale is 9.115 troy oz).
  • Spot as purchase priceUsing the spot price on the day you bought ignores the premium you paid on coins and small bars.
  • Valuing at spotSpot or the dealer's selling price overstates what you would receive; use the buy-back price.
  • Reading it as a yearly returnReturn on cost covers the whole holding period.

Frequently Asked Questions

Is a troy ounce the same as an ounce?

No. Precious metals use the troy ounce (31.1035 g); the ounce used for food and postage is 28.3495 g.

How do I convert grams to troy ounces?

Divide grams by 31.1035. A 1 kg bar is 32.15 troy oz; a 100 g bar is 3.215 troy oz.

Does this work for gold?

Yes. The formula is the same for any metal priced per troy ounce — enter gold ounces and gold prices.

Should I include dealer premiums?

Yes, in the purchase price: divide the total you paid (including premium, shipping and fees) by the ounces.

Which "current price" should I use?

For what you could actually receive, the dealer's buy-back (bid) price. Spot or the LBMA Silver Price is a market reference, not a selling price.

Can I combine several purchases?

Calculate each lot separately and add the results, or use total ounces with the weighted average price.
