Crypto Futures PnL Calculator
Calculate the profit or loss of a crypto futures position given entry price, exit price, quantity, and leverage.
How to use this tool
- Enter your entry and exit prices.
- Specify the position quantity in units or contracts.
- Select Long or Short and enter your leverage.
- Read PnL in dollars, as a percentage of notional, and as return on your margin (ROE).
Calculate your futures profit or loss before and after closing a position. Not financial advice.
Formula
Price diff = Exit − Entry (negated for short positions)
PnL ($) = Price diff × Quantity
PnL (%) = Price diff ÷ Entry × 100
Return on Equity (%) = PnL (%) × Leverage
How it works
This calculator computes the realised profit or loss of a crypto futures position by multiplying the price movement per unit by the number of contracts or units held. For short positions the sign of the price difference is reversed, so falling prices produce a profit.
Return on Equity amplifies PnL (%) by the leverage factor to show the gain or loss relative to the actual margin deposited. The calculation excludes trading fees and funding rates, so real-world results will be slightly lower.
Worked example
Worked example: long 0.1 BTC from $50,000 to $55,000
- Entry = $50,000; exit = $55,000; quantity = 0.1; direction = long; leverage = 1x.
- Price diff = $55,000 − $50,000 = $5,000.
- PnL ($) = $5,000 × 0.1 = $500.
- PnL (%) = $5,000 ÷ $50,000 × 100 = 10%.
- Return on Equity = 10% × 1 = 10%.
PnL: $500 (10%); Return on Equity: 10%.
Key terms
- PnL
- Profit and Loss — the dollar gain or loss from a trade, calculated as price change × position size.
- Return on Equity (ROE)
- PnL expressed as a percentage of the margin (equity) deposited, magnified by leverage.
- Long position
- A trade that profits when the asset price rises.
- Short position
- A trade that profits when the asset price falls; the calculator flips the sign of the price difference.
- Contracts / units
- The quantity of the asset or derivative held in the position; PnL scales linearly with this number.
Frequently asked questions
- What is the difference between PnL% and ROE%?
- PnL% is the gain as a fraction of the notional position value. ROE (Return on Equity) scales PnL% by leverage, showing the return on the margin you actually put up.
- Are fees included?
- No — this calculator shows gross PnL before trading fees. Subtract exchange fees (typically 0.02–0.1% per side) for net profit.
