Crypto profit calculator

How does the crypto profit calculator work?
The crypto profit calculator takes the fee off your money when you buy, works out how many coins that buys, values them at the sell price, and takes the fee off again.
Proceeds = coins × sell price × (1 − fee)
Profit or loss = proceeds − amount invested
The fee is entered as a percentage per trade and applied to both legs. It does not include network fees for moving coins off a platform or any spread markup built into the price.
Worked examples
Illustrative prices, 0.1% fee on each trade.
- A 10% rise: $2,000 at $58,000 buys about 0.034448 BTC after the fee. Sold at $63,800, the proceeds are about $2,195.60, a profit of about $195.60, or 9.78%, rather than the $200 the price change suggests.
- A 10% fall: the same coins sold at $52,200 bring back about $1,796.40, a loss of about $203.60.
- Break-even: with 0.1% on each side, the sell price must be about 0.2% above the buy price, around $58,116 here, just to get your money back.
How should you read the result?
The result is the change in dollar value of your money, not a tax figure. Tax rules on crypto gains vary by country and may count swaps between coins as disposals. If a platform charges a spread instead of a visible fee, enter your actual buy and sell prices, which captures the spread automatically.
Fees matter more the more often you trade: ten round trips at 0.2% each cost about 2% of the amount traded. For all the costs involved, read trading fees explained, and for the asset itself, what Bitcoin is.
What does the calculator leave out?
It assumes you sell the whole amount at one price and pay the same fee rate on both trades. In practice you might buy in several steps, pay a network fee to withdraw, or receive a slightly different price because of slippage. For a quick check of whether a trade was worth it after costs, though, the two-fee version captures what most mental arithmetic misses.
