Break-Even Win Rate
The win rate a strategy needs, at a given risk/reward, just to avoid losing money.
Also called: breakeven win rate · minimum win rate
In plain language
For any risk/reward ratio there is a win rate below which the strategy loses money and above which it makes money. That threshold is the break-even win rate.
At 1:1 you need better than 50%. At 1:2, about 33%. At 1:3, about 25%. At 1:0.5, you need 67% just to stand still.
This is why traders with modest accuracy can be highly profitable, and why traders who are right most of the time can still lose.
The formula
Break-Even Win Rate
1 ÷ (1 + Risk/Reward Ratio) × 100
- Risk/Reward Ratio
- Reward per share ÷ risk per share

Break even at a 25% win rate
At 1 : 3 you only need to be right 25% of the time to break even. Spread and commissions push that threshold a little higher.

It converts a chart setup into a testable claim: to take this trade profitably, I need to be right at least this often. Costs push the real threshold higher.
Common mistakes
- Forgetting that spread and commissions raise the true break-even.
- Assuming a high theoretical ratio is achievable when targets are rarely reached.
