Risk/Reward Ratio Calculator
Enter your entry, stop, and target to see your reward-to-risk ratio — and the exact win rate you'd need just to break even. Updates as you type. Free, no signup.
Works for longs or shorts — the calculator uses the distance from entry to your stop and target, whichever direction you trade.
Your trade
You only need to win 33.3%of the time to break even at this reward:risk. Win more than that and you're +EV — assuming you actually hit your targets and honor your stops.
Planning the ratio is easy. Knowing your realwin rate per setup is the hard part — that's what your trade history tells you.

A reward:risk ratio is meaningless on its own — it only matters relative to how often you win. The link is the breakeven win rate:
At 2:1 you break even winning just 33.3% of the time; at 1:1 you need 50%; at 1:2 (a bad trade) you need to win 66.7%. That's why chasing tiny targets with wide stops quietly destroys accounts — the required win rate becomes impossible.
The number that's hard to get right
Planning a 2:1 trade is trivial. Knowing your actual win rate for that setup — across dozens of trades, after slippage and the times you bailed early — is what tells you whether 2:1 is enough. That answer lives in your trade history. TradeFlow Quantum computes it per setup automatically. Start a free 7-day trial — no card required →
