How to use the crypto profit calculator
- Enter the price per coin you paid and the price you sold at, or a target price you are weighing up.
- Choose whether you know the number of coins or the amount of money you put in. The calculator works out the other.
- Add the trading fee charged on each side, as a percentage. Exchanges list these on their fee page, often split into maker and taker rates.
- Optionally add a tax rate to see an after-tax figure.
- Read the profit, percentage return and break-even price.
How profit, return and break-even are worked out
Worked example
You buy 0.5 BTC at $30,000 with a 0.1% fee. The coins cost $15,000 and the fee adds $15, so your total cost is $15,015. You sell at $45,000, again paying 0.1%: proceeds of $22,500 minus a $22.50 fee leave $22,477.50.
Profit is $7,462.50, a return of 49.70% on what you spent. To simply get your money back, you would need to sell at $30,060.06, not $30,000, because both fees must be covered. At a 20% tax rate, the estimated tax is $1,492.50, leaving $5,970.00.
Fees matter more on frequent, small trades
A 0.1% fee each way looks tiny, but it is charged on the full trade value, not on the profit. With a 0.5% fee on each side, a coin has to rise about 1% before you break even. Someone making several round trips a week can lose a large share of their gains this way. Card purchases and “instant buy” buttons often carry fees of 1.5% or more, plus a price spread that this calculator does not see, so check your exchange’s trade history for the true fill price.
Network withdrawal fees work differently again. They are charged as a fixed amount of the coin when you move it off an exchange, so they hit small balances hardest. Add them to your buy fee as a percentage if you withdrew before selling.
Key features
- Separate buy and sell fees, in percent.
- Enter coins or the amount invested.
- Break-even price that covers both fees.
- Optional after-tax profit using your own rate, with no assumptions about country rules.
- Works for any coin or token, and for losses as well as gains.
Practical use cases
Planning an exit. Type a target sell price before placing a limit order to see exactly what you would take home after fees.
Checking a loss. Enter a lower sell price to see the loss in money and percent, and how far the price must recover to break even.
Rough tax planning. Tax treatment varies widely. The US taxes crypto as property, with lower long-term rates after a year of holding. The UK charges Capital Gains Tax above a £3,000 annual exempt amount. In Canada, half of a capital gain is taxable. Germany currently makes private sales tax-free after one year of holding; a draft bill published in September 2026 would end this for coins bought from 2027.
