How to use it
- Choose long if you bought first, short if you sold first.
- Enter entry and exit prices.
- Enter the quantity (shares, coins or units).
- Enter the fee per side as a percentage (taker fees are often 0.05–0.1% on crypto exchanges).
The formula
Gross P/L = (Exit − Entry) × Qty (long) or (Entry − Exit) × Qty (short) · Net = Gross − fees on both sides
Long 0.25 BTC at $60,000, exit at $64,500, 0.1% fee per side: gross +$1,125, fees $31.13, net +$1,093.88 (+7.29%).
Fees add up
Fees are charged on the notional value at entry and at exit. On frequent, small moves they can consume a large share of gross profit.
ROI on position vs. on account
This calculator returns profit relative to the capital in the position. With leverage, your return on margin is higher — and so is your risk. Size positions by the amount you can lose, not by the return you hope for.
Use it before the trade too
Enter your target as the exit to see the net reward, then your stop to see the net loss. Their ratio is your real, after-fee reward-to-risk.
