Crypto profit calculator
A crypto profit calculator is useful because the headline price change and your actual result are not the same thing. Fees are charged when you buy and again when you sell, and they eat into small moves surprisingly fast. Enter the amount you invested, your buy and sell prices, and the percentage fee your platform charges per trade.
The formula
Proceeds = coins × sell price × (1 − fee)
Profit or loss = proceeds − invested
Worked example (illustrative numbers)
You invest $2,500 in bitcoin at $50,000 on a platform charging 0.2% per trade.
- Coins bought: $2,500 × 0.998 ÷ $50,000 = 0.0499 BTC.
- If you sell at $46,000: 0.0499 × $46,000 × 0.998 = $2,290.81, a loss of $209.19 (about 8.4%).
- If you sell at $55,000: 0.0499 × $55,000 × 0.998 = $2,739.01, a profit of $239.01.
At a 0.2% fee on each side, the price must rise from $50,000 to about $50,201 just to break even.
Interpreting the crypto profit calculator
The figure is your result in dollars before tax. It does not include network fees for moving coins on or off a platform, card or deposit fees, or the spread some apps build into their quoted prices, which can be much larger than the stated fee. Our guide to trading fees explained covers those extras; if a platform quotes a price above the market rate, treat the gap as an additional fee.
In many countries a profitable sale, or a swap from one coin to another, can trigger tax. Keep a record of each purchase and sale with dates, amounts and fees.
Use the calculator to test scenarios before buying: how far could the price fall before the loss would hurt, and how much of a small gain would fees absorb? It does not predict prices, and nothing here suggests which coin to buy. For the basics of custody and risk, read how crypto works.
