Crypto profit calculator
This crypto profit calculator works out the net result of buying a coin, such as bitcoin, and later selling it. It deducts a percentage fee on both trades, which is how most exchanges charge, and shows the outcome in dollars and as a percentage of the amount you put in.
The formula
Proceeds = coins bought × sell price × (1 − fee)
Profit or loss = proceeds − amount invested
Worked example (illustrative)
You invest $2,500 in bitcoin at $62,000 and sell at $58,900, paying 0.1% on each trade.
- Coins bought: $2,500 × 0.999 ÷ 62,000 = about 0.0402823 BTC.
- Proceeds: 0.0402823 × $58,900 × 0.999 = about $2,370.25.
- Result: $2,370.25 − $2,500 = a loss of about $129.75, or −5.19%.
The price fell exactly 5%, but the loss is slightly larger because of the two fees. With the same 0.1% fees, the sell price needed just to break even is 62,000 ÷ 0.999² = about $62,124.19.
How to read the result
A positive figure is your gain after trading fees; a negative figure is your loss. The result does not include the spread (the gap between buy and sell prices on the exchange), network or withdrawal fees, card or deposit charges, or any tax you may owe on a disposal. On small amounts those extras can outweigh the trading fee.
Use the calculator before you buy, not only after you sell. Enter a realistic sell price in both directions to see what a move of 10% or 20% against you would cost. Crypto prices can fall by far more than that, and what bitcoin is explains why its price has no earnings to anchor it.
If you are comparing platforms, run the same trade with each one's fee rate; the guide to trading fees lists the other charges to check. The calculator runs in your browser and does not store or send what you enter.
