Risk/Reward Ratio
How much you stand to gain compared with how much you stand to lose on a trade.
Also called: rr · r:r · r/r · reward to risk · risk to reward
In plain language
The ratio compares the distance from entry to target against the distance from entry to stop. Risk $2 to make $6 and the ratio is 1:3.
It is a property of the trade’s geometry alone. Account size and position size do not change it — only where you place the entry, the stop and the target.
Paired with your win rate, it tells you whether a strategy makes money. At 1:3 you only need to be right about 25% of the time to break even before costs. At 1:1 you need better than 50%.
The formula
Risk/Reward Ratio
Reward Per Share ÷ Risk Per Share
- Reward Per Share
- Distance from entry to take profit
- Risk Per Share
- Distance from entry to stop loss
- Break-even Win Rate
- 1 ÷ (1 + Ratio) × 100

This is the concept as a working tool. Edit any field and watch what moves — that relationship is the thing worth remembering.
- Risk Per Share
- $2
- Reward Per Share
- $6
- Risk / Reward
- 1 : 3
Break even at a 25% win rate
At 1 : 3 you only need to be right 25% of the time to break even. Spread and commissions push that threshold a little higher.

Why it matters
It converts a vague sense that a trade "looks good" into a number you can test against your actual win rate. Most losing strategies fail here, not at the entry.
Common mistakes
- Moving the target further out to manufacture a better ratio on paper.
- Chasing high ratios with targets price realistically never reaches.
- Judging the ratio without accounting for spread and commissions, which hit the small side hardest.
