Crypto Profit / Loss Calculator – PnL & ROE with Fees & Leverage
Know the number before you brag about it — or mourn it. Entry, exit, margin, leverage and fees go in; your real net profit or loss comes out, in dollars and as a return on the margin you actually risked.
A 3% price move means very different things at 1× and at 20×. This calculator works the way exchanges settle: quantity = (margin × leverage) ÷ entry; gross PnL = quantity × the price move in your direction; then it subtracts real trading fees charged on both the entry notional and the exit notional at the fee rate you set (0.06% is a typical taker fee — edit it to match your exchange and tier). The headline result is net PnL in dollars plus ROE — the return on your margin — which is the honest percent for a leveraged trade. Set leverage to 1 to use it as a plain spot profit calculator. Funding fees on perpetual contracts are not included.
How to use it
Enter entry and exit prices — where you got in and where you closed (or plan to).
Add margin and leverage — the money you put down and the multiplier; use 1× for spot.
Set the fee — your exchange's per-side fee percent.
Pick long or short — and read net PnL, ROE, quantity and the fee breakdown.
What you get
Net, not gross — fees on both sides are deducted before the headline number.
ROE % — profit or loss as a percent of the margin you risked.
Long & short — shorts profit from falling prices, handled correctly.
Full breakdown — quantity, notional, gross PnL and each fee shown separately.
Frequently asked questions
How is crypto PnL calculated with leverage?
Quantity = (margin × leverage) ÷ entry price. Gross PnL = quantity × (exit − entry) for a long, or × (entry − exit) for a short. Net PnL subtracts entry and exit fees, each charged on that side's notional value.
What is ROE in trading?
Return on equity — here, your net PnL divided by your margin, as a percent. A $15 profit on a $100 margin is +15% ROE even if the coin itself only moved 1.5%, because leverage multiplies the move on your margin.
What fee should I enter?
Your exchange's taker or maker fee per trade. 0.06% is a common taker fee on large futures exchanges; VIP tiers and maker orders are lower. The calculator defaults to 0.06% and you can edit it.
Why is my exchange PnL slightly different?
Funding payments on perpetuals, partial fills at different prices, and fee discounts or rebates all shift the final number a little. This calculator covers price PnL minus trading fees.
