About the Gold Investment Return Calculator
This gold investment return calculator shows what you actually earned on physical gold — bars or coins — rather than the headline change in the spot price. You pay a premium above spot when you buy, a dealer usually bids below spot when you sell, storage and insurance cost money each year, and gains may be taxed. All of those reduce your return, sometimes dramatically over short holding periods.
Enter how many ounces you bought, the spot price and premium when you bought, the spot price and dealer discount when you sold (or would sell today), how many years you held, and any annual storage cost. The calculator returns net profit, total return, your annualized return (CAGR) and the spot price you need just to break even.
In the United States, gains on physical gold are taxed as collectibles at a maximum federal rate of 28% when held more than a year; enter your own effective rate (or 0 to ignore tax). Results are estimates for planning and comparison, not tax advice.
With the default inputs, the annualized return (cagr) is 13.22%. Change any value above to recalculate instantly.
How to use the gold investment return calculator
- 1Enter the ounces you bought and the spot price at the time.
- 2Add the premium you paid over spot (check your invoice).
- 3Enter the spot price at sale (or today) and the dealer’s buy-back discount.
- 4Enter the years held, yearly storage cost and, optionally, your tax rate on the gain.
- 5Compare your annualized return with the spot price CAGR to see the cost drag.
Formula and method
Your purchase cost is the spot price plus the dealer premium, and your sale proceeds are the later spot price minus the dealer’s discount (the bid below spot). Storage and insurance are counted as a flat yearly cost multiplied by the years held. Tax is your entered rate applied to the gain (proceeds minus cost basis); storage is not deducted from the taxable gain, which is how it generally works for individual US investors.
Total return is net profit divided by the purchase cost. The annualized return is the compound annual growth rate that turns your purchase cost into cost plus net profit over the holding period, so it can be compared directly with the spot-price CAGR, a savings rate or a stock index. Break-even spot is the price at which the discounted sale would just recover the purchase cost plus storage.

Worked examples
10 oz bought at $2,000, sold at $4,000 after 5 years
Buying cost 10 × $2,000 × 1.04 = $20,800 and selling brings 10 × $4,000 × 0.98 = $39,200. After $500 of storage the profit is $17,900, an 86.1% total return. Spot grew 14.87% a year, but costs cut your annualized return to 13.22%.
One coin held two years in a flat market
Spot rose about 3.8%, yet the 5% premium and 3% sell discount mean you get back $2,619 for a $2,730 purchase — a $111 loss. Spot would need to reach $2,814 just to break even.
20 oz held 8 years with 28% collectibles tax
The gain on sale is $78,400 − $37,080 = $41,320, and 28% of that is $11,569.60 in tax. After $1,200 of storage the net profit is $28,550, which works out to 7.40% a year versus 10.50% for the spot price.
Frequently asked questions
How is profit on physical gold taxed in the US?+
The IRS treats gold coins and bullion as collectibles. Long-term gains (held more than a year) are taxed at your ordinary rate up to a maximum of 28%; short-term gains are taxed as ordinary income. State tax may also apply.
Why is my gold return lower than the change in the gold price?+
You buy above spot (the premium) and usually sell below it (the dealer’s bid), and storage or insurance adds yearly costs. On a short holding period these frictions can easily exceed the price gain.
What is a typical premium on gold bullion?+
Premiums vary with product size and demand. Larger bars carry the smallest premiums, while one-ounce sovereign coins cost more and fractional coins much more. Check your dealer’s current buy and sell prices to see the full round-trip spread.
What is a good annualized return on gold?+
There is no fixed benchmark: gold pays no income, so all of its return comes from price changes, which have swung from long flat or falling periods to sharp rallies. Compare your result with inflation and with what the same money would have earned elsewhere.
Does this work for silver or platinum?+
Yes. The math is the same for any physical metal — enter the ounces, spot prices, premium and discount for that metal. Silver typically has higher percentage premiums and spreads than gold.
