Calculators
Do the math before the order.
Four calculators for perpetual futures. Each one shows its formula and a worked example, and runs in your browser — nothing you type leaves the page.
- 01 Position size calculator Size a crypto futures position from your account balance, risk per trade and stop-loss, with taker fees on entry and exit included.
- 02 Liquidation price calculator Estimate the isolated-margin liquidation price of a perpetual futures position with the published Binance, Bybit and Hyperliquid formulas.
- 03 Funding cost calculator Work out how much funding a perpetual futures position pays or receives over a holding period, with the simple APR of the rate.
- 04 PnL and ROE calculator Calculate the profit or loss and return on equity (ROE) of a crypto futures trade from entry, exit, size, leverage and fees.
Results are estimates for planning. Exchanges apply their own fees, funding and tier rules; check the order preview on your venue before you trade.
Trade every venue from one tab.
Binance, OKX, Bybit, and Hyperliquid with news, charts, and one-command orders. Included with Ninja Squad Pro membership.
