Break-even win rate = 1 ÷ (1 + reward:risk). Fees come off every winner and add to every loser, so tight stops need a higher win rate than the ratio suggests.

FAQ

How is the risk/reward ratio calculated?
Distance from entry to target divided by the distance from entry to stop. Entry $100, stop $98 and target $106 is $6 of reward for $2 of risk, a 3:1 ratio.
What win rate do I need to break even?
1 ÷ (1 + reward:risk). At 1:1 you need 50%, at 2:1 about 33%, at 3:1 25%. Fees push that number up, which the calculator shows.
Is a higher risk/reward always better?
No. Far targets get hit less often. What matters is expectancy: win rate × average win − loss rate × average loss. A 1.5:1 setup that wins 55% of the time beats a 4:1 setup that wins 15%.
