Crypto Futures Calculators
Six pure-math tools for perpetual-futures pricing: liquidation price, PnL after fees, position size, margin, funding cost and break-even. Per-exchange maintenance and fee rates included.
Liquidation Price
Where the position closes out. Enter entry, leverage and direction; we apply the right Binance / Bybit / OKX maintenance-margin tier.
Open →Futures PnL
Net profit after open / close fees on a perpetual round-trip. Maker vs taker, exchange-specific rates.
Open →Position Size
Risk-based sizing — given a max loss in USD and a stop-loss distance, get the position notional that respects that risk.
Open →Futures Margin
Initial margin required to open a perpetual position, plus the entry fee. Per-exchange tier rates.
Open →Funding Cost
Estimate funding paid or received over a holding window. Pre-fills the live 8h rate from BTC, ETH, SOL and other major perps.
Open →Break-even
Price you need to cover open / close fees and a holding window's funding. The honest minimum target.
