Risk-Reward Ratio: How It Works With Win Rate
Risk-reward ratio compares the distance to your stop with the distance to your target. Risking 50 points to make 100 is a 1:2 ratio, usually written as 2R.
The ratio on its own says nothing about whether a strategy makes money. What determines profitability is the ratio combined with how often you win, and those two variables move in opposite directions.
Breakeven win rates
For any risk-reward ratio there is a win rate at which you break even. Below it you lose money, above it you make money.
The relationship is simple arithmetic: breakeven win rate = 1 ÷ (1 + R). At 1R you need to win more than half your trades; at 3R you only need to win a quarter of them.
- 1R target — breakeven at 50% win rate
- 2R target — breakeven at 33%
- 3R target — breakeven at 25%
- 5R target — breakeven at 17%
The trade-off nobody mentions
Higher targets are further away, and further targets are hit less often. Moving from a 2R target to a 5R target on the same setup does not multiply your profit — it cuts your win rate, often by more than the extra reward compensates for.
A strategy winning 50% at 2R makes money comfortably. The same setup stretched to 5R might win 15%, which is below its breakeven. The correct target is the one price actually reaches with reasonable frequency, which is a question about the market and not about the ratio.
Expectancy
Expectancy is the number that actually matters: (win rate × average win) − (loss rate × average loss). It tells you what you make per trade on average.
A 40% win rate at 2R has an expectancy of (0.4 × 2) − (0.6 × 1) = +0.2R per trade. Over 100 trades that is +20R. Optimising a strategy means maximising expectancy, not maximising either the ratio or the win rate in isolation.
Psychology under a drawdown rule
High-R strategies have long losing streaks by design. Winning 25% of the time means five or six consecutive losses happen regularly, and you must keep taking the setup through them or the winners never arrive.
On an evaluation with a total drawdown limit, that streak has to fit inside the account. If you risk 1% per trade at 25% win rate, a six-loss streak costs 6% — most of an 8% allowance. Either reduce risk per trade or choose a target with a higher hit rate. Both are valid; ignoring the interaction is not.
Frequently asked questions
What is a good risk-reward ratio?
There is no universally good ratio. What matters is whether your win rate exceeds the breakeven rate for the ratio you use. A 1.5R strategy at 55% win rate is more profitable than a 5R strategy at 15%.
Is a higher risk-reward always better?
No. More distant targets are reached less often, so raising the target lowers the win rate. Past a point the win rate falls faster than the reward rises and total profitability decreases.
How do I calculate expectancy?
Expectancy = (win rate × average win in R) − (loss rate × average loss in R). A positive result means the strategy makes money over a large sample; a negative result means no amount of discipline will save it.
