Can the math pass — and how many losses blow it?

The Prop-Firm Challenge Calculator is a planning tool that works out the arithmetic of passing a funded-account evaluation like an FTMO-style challenge. It answers three questions: how many winning trades it takes to reach the profit target, how long a losing streak would breach the drawdown limit, and what win rate you'd need just to break even at your reward-to-risk.
Trades to target = profit target ÷ (risk per trade × reward-to-risk). Losses to blowout = maximum drawdown ÷ risk per trade (fixed sizing). Break-even win rate = 1 ÷ (1 + reward-to-risk), i.e. the win rate at which average wins exactly offset average losses. These are deterministic ratios, not simulations.
There is no single number — it depends on your reward-to-risk. This FTMO risk calculator shows the break-even win rate (1 ÷ (1 + R:R)); you need to clear that plus a margin to reach the profit target before the drawdown limit stops you.
Divide the profit target by your expected profit per winning trade (risk × reward-to-risk). Fewer, larger trades reach the target in less time but each carries more drawdown risk.
No. It shows what the rules mathematically require given your settings; it cannot predict whether your trades will actually hit those win-rate and streak conditions.
Keep in mind: These figures assume fixed position sizing and a constant win rate — they show what the challenge rules demand arithmetically, not whether your trading will meet those demands or survive the daily-loss and consistency rules many firms enforce.
