Calculate the risk-to-reward ratio of any trade setup before you take it. The R:R ratio tells you how much you stand to gain for every dollar at risk — a critical filter for profitable trading.
Why Risk-Reward Matters More Than Win Rate
A common misconception is that you need a high win rate to be profitable. In reality, your risk-to-reward ratio matters far more. Consider:
- With a 1:3 R:R, you only need a 26% win rate to break even
- With a 1:2 R:R, you need a 34% win rate
- With a 1:1 R:R, you need a 50% win rate
- With a 1:0.5 R:R, you need a 67% win rate
This is why professional traders focus on finding asymmetric setups where the reward significantly outweighs the risk, rather than chasing high win rates with poor R:R.
Frequently Asked Questions
What is a good risk-reward ratio?
Most professional traders look for at least 1:2 (risk $1 to potentially make $2), with 1:3 or higher being preferred. Setups below 1:1.5 are typically rejected unless the win rate is very high.
How do I calculate risk-reward ratio?
R:R = (Take Profit − Entry) ÷ (Entry − Stop Loss). For a long trade with entry at $100, TP at $110, and SL at $95: R:R = (110-100) ÷ (100-95) = 10/5 = 1:2.
What's the breakeven win rate formula?
Breakeven Win Rate = 1 ÷ (1 + R:R Ratio). For a 1:3 R:R: 1 ÷ (1+3) = 0.25 = 25%. This means you only need to win 25% of trades to break even with a 1:3 R:R.
Should I take trades with R:R below 1:1?
Generally no, unless your win rate is exceptionally high (above 70%). Trades with R:R below 1:1 have an unfavorable risk profile — you lose more on losers than you make on winners, requiring a high success rate to be profitable.
