How to use
Risk reminder: Cryptocurrency prices are highly volatile. This calculator estimates profit from numbers you enter — it is not financial advice.
Type the price you paid, the amount you bought, the price you expect to sell at, and your exchange sell fee. Press Calculate to see cost basis, gross proceeds, the trading fee, net profit and ROI.
ROI is the net profit divided by your cost basis, shown as a percentage. A negative ROI means the trade loses money after fees. Fees are the silent tax on every trade, so test a few rate assumptions.
FAQ
Does this use live crypto prices?
No. Every figure is typed in by you. Prices are manual on purpose — it keeps the tool zero-maintenance and works offline.
Why is my net profit lower than I expected?
Sell fees shrink gross proceeds. Even a 0.1% fee adds up on large trades, and a 1% fee can erase a thin margin.
Is the ROI after fees?
Yes. ROI here is net profit divided by cost basis, so the sell fee is already included in the result.
