This calculator is based on the rule set reviewed on 2026-03-21.

Who should use this calculator
Best for checking whether your real win rate and risk settings are even compatible with Apex Trader Funding's drawdown budget before you buy or reset.
Where this tool can mislead you
Risk-of-ruin models assume your edge and position sizing stay stable. They become misleading if you revenge trade, increase risk after losses, or trade multiple correlated setups at once.

Frequently Asked Questions
What is Apex Trader Funding's daily loss limit?
Apex Trader Funding's daily loss limit is not enforced as a percentage (check dollar limits per account size). For the $25,000 account, the daily limit is based on the trailing drawdown floor.
What drawdown type does Apex Trader Funding use?
Apex Trader Funding uses trailing intraday (floor moves with every tick). The floor moves up in real-time as your equity reaches new highs during the session.
What win rate do I need to pass Apex Trader Funding?
The minimum win rate depends on your reward-to-risk ratio. With a 1.5:1 R:R, a 45% win rate gives you a positive expectancy. With 1:1 R:R, you need above 55%. For Apex Trader Funding's fixed dollar max drawdown, lower risk per trade (0.5-1%) dramatically reduces your risk of ruin even with modest win rates.
What is a good risk of ruin percentage for prop trading?
A risk of ruin below 5% is considered safe for prop firm trading. Below 1% is excellent. Most failed prop firm traders have risk of ruin above 30% because they risk too much per trade (2%+ of account) or have a negative expectancy strategy.
