Position Size Calculator

Enter your entry, stop loss, and risk — either as a dollar amount or as a % of your account. Get position size, fee-adjusted R:R targets, and the margin you'd lock at the leverage you pick on a USDT perp. Three modes: USDT Perp, Spot USDT, and Spot BTC for BTC-quoted crosses like ETHBTC.

Targets are recomputed to net exactly 1R / 2R / 3R after fees — not the naive math most calculators show.
