Position size calculator
Work out how large a crypto futures position should be for the amount you're prepared to lose. Enter your balance, risk, entry and stop: everything runs in your browser and nothing is sent anywhere.
- Enter an account balance greater than 0.
- Enter a risk greater than 0, as a percentage or in USDT.
- Risk can't be more than 100% or more than your balance.
- Enter an entry price greater than 0.
- Enter a stop price greater than 0.
- For a long, the stop must be below the entry; for a short, above it.
- The target price must be greater than 0, or leave it empty.
- For a long, the target must be above the entry; for a short, below it.
- Leverage must be between 1 and 125.
- The margin required is larger than your balance.

Liquidation price depends on your exchange's maintenance margin tiers, so this calculator doesn't estimate it; read it from the position itself. More on this: How to avoid liquidation in USDⓈ-M futures
How the calculator works
- It takes the amount you're prepared to lose, as a percentage of your balance or a fixed USDT amount, and divides it by the distance between your entry and your stop. The result is the quantity; multiplied by the entry price it gives the notional value, and divided by the leverage, the margin the position needs.
- Example: 1% risk on a 10,000 USDT balance is 100 USDT. A long at 60,000 with a stop at 59,400 has a stop distance of 600, so the size is 0.1667 coins, about 10,000 USDT notional and 2,000 USDT of margin at 5x. With a target at 61,800, the risk-reward is 1 : 3, the PnL at the target about 300 USDT and the ROE 15%.
- Leverage changes the margin and how close liquidation sits, not the loss at your stop. The position sizing guide explains the full method.
