How this calculator works
Prop firms enforce two killer rules: a hard daily drawdown limit and a total max loss limit. Most failures come from breaching the daily DD via oversized positions.
The calculator translates your parameters into concrete dollar budgets, a recommended lot size and a realistic trades-to-target estimate.
Trading example
$100k challenge, 5% daily DD, 0.5% risk per trade → daily budget $5,000, safe risk $500/trade. With 1.5R average wins you need ~11 winning trades to hit 8% target.
