Question 1

What is the break-even win rate?

Accepted Answer

The break-even win rate is the minimum percentage of trades that must be profitable for a strategy to neither gain nor lose money over time. Formula: Break-Even Win Rate = 1 ÷ (1 + R:R Ratio). At 1:2 R:R, you need to win 33.3% of trades to break even.

Question 2

If my win rate is above breakeven, does that mean I will be profitable?

Accepted Answer

No. Commissions, spreads, and slippage reduce your effective R:R in live trading. Also, expectancy requires a statistically significant sample — a 60% win rate over 10 trades may just be luck. Track results across 100+ trades.

Question 3

How do I use this calculator to evaluate a strategy?

Accepted Answer

Identify the R:R ratio your strategy typically achieves, calculate the break-even win rate, then compare to your historical win rate from backtesting or live trading. If your win rate comfortably exceeds the break-even threshold, the strategy has a mathematical edge.

Question 4

Does a higher R:R always require a lower win rate?

Accepted Answer

Yes — mathematically, a higher R:R ratio lowers the required win rate. But in practice, high R:R trades (e.g. 1:5) require price to travel further without hitting your stop, so real-world win rates on high R:R setups may be lower than expected.
