Crypto Profit Calculator

By CalcSmith · Published Nov 5, 2026 · Last updated Nov 5, 2026

Work out the profit — or loss — on a crypto trade before you sell. Enter what you invested (or how many coins you hold), your buy and sell prices, the trading fees on both sides and an optional tax rate, and see net profit, ROI and the break-even sell price.

How to calculate crypto profit

1. Divide the investment by the buy price to get the coins bought.
2. Multiply the coins by the sell price for the sale value, then subtract the sell fee for the proceeds.
3. Subtract the investment and the buy fee from the proceeds to get the net profit.
4. Divide the net profit by the total paid (investment plus buy fee) and multiply by 100 for the ROI.

How this crypto profit calculator works

The calculator follows the money through the whole trade. First it works out how many coins your investment bought: investment divided by the buy price. Then it values those coins at your sell price, subtracts the sell fee, and compares what is left against everything you paid — the investment plus the buy fee. The difference is your net profit or loss, and dividing it by the total paid gives the return on investment (ROI). The break-even price is the sell price at which the trade makes exactly zero — always a little above your buy price, because it must cover both fees. It runs entirely in your browser: no wallet connection, no price fetching, nothing sent anywhere — enter the prices yourself.

If you bought in several lots, use your average buy price: total cash invested divided by total coins held. If you know how many coins you hold, switch the first field to "coin quantity" instead. The optional tax field applies your rate only to positive profit, as a simplified estimate — real crypto tax depends on holding period, income and country.

The crypto profit formula

Two details catch people out. First, fees bite twice — the buy fee on the investment, the sell fee on the sale value — which is why break-even sits above the buy price. Second, ROI is measured against the total paid, fees included, not the headline investment.

Worked example

You invest $1,000 in a coin at a buy price of $60,000, and later sell when the price reaches $75,000. Your exchange charges 0.1% on both sides. The $1,000 buys 0.0166667 coins. At $75,000 those coins are worth $1,250.00. The sell fee takes 0.1% of that, $1.25, leaving $1,248.75 of proceeds. The buy fee was $1.00, so the total paid was $1,001.00. Net profit is $1,248.75 − $1,001.00 = $247.75, an ROI of 24.75%. And the break-even sell price is $60,000 × 1.001 ÷ 0.999 = $60,120.12: sell below that and the fees eat the gain, even though the price rose. (Source: IRS virtual currency FAQ.)

Fees: the quiet profit killer

• Two bites, not one. A 0.1% fee sounds like nothing, but charged on both sides it is 0.2% of the trade — and on a frequently traded account it compounds into real money.
• Maker vs. taker. Many exchanges charge less for limit orders (maker) than for market orders (taker). On large trades the gap between a 0.1% and a 0.25% tier can exceed the profit on a small price move — use your actual rates above.
• Spread is a hidden fee. The gap between the exchange's quoted buy and sell prices is a cost too — but the prices you enter are the ones you transact at, so the spread is already inside your numbers.
• Network and withdrawal fees. Moving coins off an exchange usually costs a flat network fee, which this calculator does not include — subtract it from the proceeds yourself, because on small trades it can outweigh the trading fees.

Taxes on crypto gains

In the United States, the IRS treats virtual currency as property, not currency, so selling for more than you paid generally creates a taxable capital gain — and swapping one coin for another is a taxable event too, even though no dollars changed hands (source: IRS virtual currency FAQ). How long you held matters: gains on assets held over a year are usually taxed at lower long-term rates. This calculator's tax field is only a rough planning estimate. Keep records of every price, fee and date. Beyond a small, simple trade, take these numbers to a tax professional.
