How it works

What this calculator does

It computes the profit or loss on a crypto trade — long or short — including position size, leverage and trading fees, then expresses the result as return on equity (ROE) so leveraged outcomes are comparable.

The formulas

gross PnL = (exit − entry) × quantity × direction

where direction is +1 for a long and −1 for a short. After subtracting fees:

ROE = net PnL / (notional / leverage)

The term notional / leverage is the margin you actually posted.

Worked example

You long 1 BTC at $60,000 and exit at $66,000 — gross PnL is (66,000 − 60,000) × 1 = $6,000, a 10% move on the asset. With 10× leverage your margin was 60,000 / 10 = $6,000, so ROE is 6,000 / 6,000 = 100%. Leverage multiplies the percentage return — and the loss if price moves the other way.

What it deliberately does not do

It uses the prices and fees you enter, not live market data, and it ignores funding payments and liquidation mechanics. Leverage cuts both ways: the same 10× that turned 10% into 100% turns a 10% adverse move into a wipeout. This is an estimate for education, not investment advice.

Frequently asked questions

How do I calculate crypto profit and loss?
Multiply the price change by your quantity and direction: (exit − entry) × qty for a long, the reverse for a short, then subtract fees. This tool also converts it to a percentage return.
What is ROE in leveraged crypto trading?
Return on equity is profit measured against the margin you posted, not the full position value: net PnL / (notional / leverage). At 10× leverage a 5% price move is roughly a 50% ROE.
How does leverage change my profit and loss?
Leverage multiplies both. 10× turns a 10% favorable move into about 100% on your margin — and a 10% adverse move into a near-total loss. Higher leverage means a much smaller move can wipe out your position.
How do I calculate profit on a short position?
You profit when price falls: (entry − exit) × qty, minus fees. Enter the trade as a short and the calculator flips the sign automatically.
Does this account for funding fees and liquidation?
No. It covers trading fees but not perpetual funding or forced liquidation. For the price where a leveraged position gets liquidated, use the liquidation price calculator. Results are estimates, not investment advice.
