What is Breakeven Win Rate?
The minimum win rate needed for a strategy to break even given its risk/reward ratio — below this, the strategy loses money long-term.
The breakeven win rate is the win percentage at which a strategy neither makes nor loses money over a large number of trades, given its specific risk/reward ratio.
Formula:
Breakeven Win Rate = 1 / (1 + R:R)
Where R:R is expressed as reward ÷ risk.
Breakeven win rates by R:R:
| R:R Ratio | Breakeven Win Rate |
|---|---|
| 1:0.5 | 67% |
| 1:1 | 50% |
| 1:1.5 | 40% |
| 1:2 | 33% |
| 1:3 | 25% |
| 1:4 | 20% |
| 1:5 | 17% |
How to use this:
Before deploying a strategy live, calculate its breakeven win rate. Then ask: "Is my expected win rate realistically above this level?"
If you're targeting a 1:2 R:R, your strategy needs to win more than 33% of trades to be profitable. If backtesting shows a 45% win rate with 1:2 R:R — you have significant positive expected value.
The implication for tight targets:
Strategies with very tight take-profits (1:0.5 or 1:1) require win rates of 50–67% just to break even. These are difficult to achieve consistently and are very sensitive to fee drag, especially at higher frequencies.
Use the risk/reward calculator to find the breakeven win rate for any setup.
