How to use this calculator

Every prop firm sets two hard limits: a daily loss limit and a maximum (total) drawdown. Breach either and the account is gone. This calculator turns those percentages into real dollar caps, then shows how many full-risk losing trades you can take before you hit each wall, so you can size positions that survive a losing streak. Prop firm rules change often; always confirm the current parameters on your firm's official website.

FAQ

What is a prop firm drawdown limit?

It is the maximum your account is allowed to lose. Firms usually set two: a daily loss limit that resets each trading day, and a maximum (total) drawdown for the whole account. Hitting either one ends the challenge or closes the funded account.

How much should I risk per trade?

Most professional prop traders risk 0.5% to 1% of the account per trade. At 0.5% on a 100k account that is $500, so you could take ten full-risk losses before a 5% daily limit. Lower risk survives longer losing streaks.

How is the lot size calculated?

Lot size = your dollar risk per trade divided by (stop loss in pips multiplied by the pip value). This tool assumes a major FX pair at about $10 per pip per standard lot. Confirm the pip value for your specific instrument.
