TopStep Margin Calculator
Calculate the required margin for any position on TopStep. Enter your instrument, lot size, leverage, and price to see margin requirements, free margin remaining, and max lots available. TopStep uses trailing eod (floor moves up at end of day) with a 2% daily loss limit and 3% max drawdown. This calculator is based on the rule set reviewed on 2026-03-21.
TopStep provides leverage on funded accounts, but using too much leverage relative to your account size is a fast path to breaching drawdown limits. This calculator shows how much margin a position requires and how many lots you can safely open at your leverage level.
Who should use this calculator
Best for leveraged traders who need to know whether a position is even feasible before the order is placed.
Where this tool can mislead you
Enough free margin does not mean the trade is rule-safe. Margin availability and drawdown safety are different constraints.

How is margin calculated in forex?
Margin = (Lots x Contract Size x Price) / Leverage. For example, 1 lot of EUR/USD at 1.0800 with 1:30 leverage requires (1 x 100,000 x 1.0800) / 30 = $3,600 margin. Higher leverage means less margin required but more risk exposure.
