Risk / Reward Ratio Calculator + Break-Even Win Rate
Enter entry, stop and target to instantly see your risk-to-reward ratio, the win rate needed to break even, and the expected value of the trade.
You're risking $5.00 to make $15.00 per share.
Win above this and you're profitable long-term.
Profitable at this win rate.
R:R alone is not enough
Everyone obsesses over “at least 1:3 risk-to-reward.” But R:R only matters paired with your win rate. A 1:5 setup with a 10% win rate loses money. A 1:1.2 setup with 60% win rate prints.
The break-even formula
Break-even win rate = 1 ÷ (1 + R:R). A 1:2 trade breaks even at 33% win rate. A 1:1 trade breaks even at 50%. Anything you win above that line is pure profit.
Expected value
EV = (win rate × reward) − ((1 − win rate) × risk). Positive EV = profitable system over time. Negative EV = no matter how hyped the setup, you'll lose money taking it.
