Risk reward calculator
Free risk/reward ratio calculator. See your R multiple, the break-even win rate you need and your expectancy per trade.
Long trade: you risk €100.00 to make €300.00. You need to win more than 25% of trades like this to be profitable.
How the risk reward calculator works
The reward-to-risk ratio compares what a trade can make at its target with what it loses at its stop. A 2 R trade makes twice what it risks.
Break-even win rate = 1 ÷ (1 + R). At 2 R you only need to win 33.4% of trades to break even. Expectancy = win rate × R − loss rate, in R per trade; above zero, the strategy makes money over many trades.
Know your numbers after the trade, too
Lumivar is a trading journal that turns every trade into a P&L calendar, win rate, average R and the patterns behind your results. There's a free plan.
