Crypto position size calculator

Turn a planned USDT loss and stop distance into base units, notional and estimated initial margin for a simple linear crypto position. PropGo’s current trailing-daily and static-overall rule room stays beside the calculation.

Scope and limitations

This is educational arithmetic for a simple linear instrument. It does not model fees, spread, slippage, funding, liquidation, mark-price triggers, gaps, contract step/minimums, maintenance margin, other open positions, or later equity changes. Round down to supported precision, verify inside Bybit Demo, and leave your own buffer. PropGo’s monitored snapshots and locked challenge rules remain authoritative.

The risk-first inputs follow the general position-sizing sequence explained by CME Group Education: choose a stop and decide the amount you are willing to risk before sizing. Nothing here is financial or trading advice.
