What does this calculator do?
It computes the actual net profit of a crypto trade after exchange fees, plus the ROI percentage and the break-even price you would need to sell at just to recover your costs. Crypto fees are deceptively important: a 1% round-trip fee on a 5% gain eats one fifth of your profit. The break-even price is what you should mentally treat as the new “zero” — anything below it and you’re still underwater. The Bitcoin time-machine widget below uses anchor BTC prices ($0.10 in 2010, $1K in 2013, $15K in 2017, $8K in 2020, $60K in 2024) to show what an arbitrary investment would be worth today, assuming you held without selling.
How to use the calculator
- Enter the buy price per coin in USD on the day you bought.
- Enter the sell price — your target or actual exit price.
- Enter the quantity of coins. Decimals are fine (e.g. 0.0125 BTC).
- Set total fees as a percentage applied to both the buy and sell legs.
- Read your net profit, ROI and break-even price. Use the time-machine below for nostalgia.
How the math works
Profit equals gross sale minus invested capital, minus fees on both legs. ROI is profit divided by invested capital. Break-even price is the buy price scaled up by twice the fee percentage to recover both legs.
Profit = (Sell × Qty − Buy × Qty) − Fees
ROI % = (Profit / Invested) × 100
Break-even Price = Buy × (1 + 2 × Fee%)
