Crypto Profit Calculator
Most crypto profit calculators subtract entry from exit and call it done - which quietly ignores the fee that both sides of every trade pay. Buy $30,000 of Bitcoin at 0.1% and you received $29,970 of exposure; sell at 'break-even' and the exit fee closes the round trip $60 in the hole. This calculator fees both sides explicitly and derives the number that actually matters: the sell price at which you are truly flat.
From there it is honest P/L: net profit, ROI on capital-at-risk including the buy-side fee, and a note that keeps the long-run picture visible - fees compound with trade frequency, which is how active traders silently give back double-digit percentages a year. Inputs are remembered, results land in the tab title, and the share link carries the whole scenario.
How to use
- Enter buy price, sell price and quantity - profit appears with default fees.
- Set your exchange's per-side fee (0.1-0.5% is typical for spot).
- Read net P/L, ROI and break-even - then try the fee the spread really costs you.
Frequently asked questions
How is break-even calculated?
Break-even sell price = buy price × (1 + fee) ÷ (1 − fee). At 0.1% per side that is 0.2% above your entry: buy at $60,000 and the trade is only whole at $60,120.1. The formula compounds both fee directions, which is why it is slightly larger than the naive entry × (1 + 2×fee).
Do the fees include spread and slippage?
No - the fee field models the exchange's commission only. The spread on illiquid pairs and slippage on market orders are real costs too; many traders fold them in by raising the fee percent until it matches their all-in cost, and the calculator updates break-even live.
Does it work for any coin or only Bitcoin?
Any asset priced per unit: ETH, SOL, DOGE, gold ounces, or fractional coins - quantity takes decimals, so 0.5 BTC works exactly like 500 DOGE. Leverage, funding rates and tax lots are out of scope; this is the spot round-trip, modeled precisely.
Is profit before or after tax?
Before - crypto disposals are taxable events in most jurisdictions, and short-term rates apply to trades held under a year. The note keeps the trading-cost picture honest; for the tax picture, your jurisdiction's rules on cost basis and holding periods apply on top.
