Risk / Reward Calculator
Compute the R-multiple of any trade plan and find the win rate you'd need for positive expectancy. The fastest way to filter out asymmetric trades that don't pay you enough for your risk.
Enter entry, SL and TP
The calculator computes R-multiple, pip distances, direction and break-even win rate.
The formula
reward = |take_profit − entry|
R = reward / risk
break_even_win_rate = 1 / (1 + R) × 100
Frequently asked questions
What is a good risk-to-reward ratio?⌄
Most professional traders look for at least 1:2 (risk 1 unit to make 2). At 1:2 R, you only need to win 33% of the time to be profitable before costs. 1:3 R is considered excellent. Below 1:1 is generally hard to make work because the required win rate rises above 50%, leaving no margin for slippage and commissions.
How is the break-even win rate calculated?⌄
Break-even win rate = 1 / (1 + R) × 100, where R is the R-multiple. At 1:1 R you need to win 50% to break even. At 1:2 you need 33.3%. At 1:3 you need 25%. At 1:0.5 you need 67% — usually unrealistic.
Does this account for fees or slippage?⌄
No — it's a pure R-multiple analysis based on the entry/SL/TP you enter. Real-world fills face slippage and broker commissions, which effectively widen risk and narrow reward. For trades very close to your break-even win rate, factor in 0.5 – 1 pip of slippage on each side before deciding.
What does 'Excellent / Good / Acceptable / Poor' mean?⌄
Excellent = R ≥ 3.0 (need < 25% win rate). Good = R ≥ 2.0 (< 33%). Acceptable = R ≥ 1.0 (< 50%). Poor = R < 1.0 (> 50% required, very hard). These tiers are TradeVisor's house defaults — many sophisticated strategies trade Poor R with high win rates, but most retail setups should aim for Good or better.
