What Is Risk-Reward Ratio in Trading?
A short definition of risk-reward ratio, the formula for calculating it from a planned stop and target, a worked example, and how it differs from R-multiple and expectancy, which measure a trade after it closes rather than before entry.

In short. The risk-reward ratio compares how much you stand to gain on a trade to how much you stand to lose, set before you enter. A trade with a $30 planned stop and a $90 planned target has a 1:3 risk-reward ratio: you are risking one dollar to make three. It is a planning number, based on where you place your stop and target, not a report on how the trade actually turned out.
What risk-reward ratio means
Risk-reward ratio, sometimes written reward-to-risk, measures the potential profit of a trade against the potential loss, both estimated before the position is opened. According to Babypips Forexpedia, it is a core risk management concept that helps traders judge whether a setup is worth taking given the level of risk involved.
The ratio itself needs two prices you decide in advance: a stop-loss, which sets your planned loss, and a target, which sets your planned gain. Neither has happened yet. That is the key difference from a metric like R-multiple, which measures what a trade actually returned once it closed.
How to calculate risk-reward ratio
The formula is straightforward:
Risk-reward ratio = Potential profit / Potential loss
Say you plan to buy at $100, place a stop-loss at $97, and set a target at $109. Your potential loss is $3 per share, and your potential profit is $9 per share. Divide $9 by $3 and the ratio is 3, usually written 1:3 or 3R planned. You are planning to risk one dollar to make three.
| Ratio | What it means | Example |
|---|---|---|
| 1:1 | Planned gain equals planned loss | $5 stop, $5 target |
| 1:2 | Planned gain is twice the planned loss | $5 stop, $10 target |
| 1:3 | Planned gain is three times the planned loss | $5 stop, $15 target |
| 2:1 | Planned loss is twice the planned gain (unfavorable) | $10 stop, $5 target |
Important. A favorable risk-reward ratio does not by itself mean a trade is profitable over time. A 1:3 setup that only hits its target 20% of the time can still lose money overall, while a 1:1 setup that wins 60% of the time can be solidly profitable. Ratio has to be read together with win rate, not on its own, a distinction covered in why your win rate lies without R-multiple.
Risk-reward ratio vs R-multiple vs expectancy
These three terms get mixed together often because they all involve a ratio to risk, but each answers a different question at a different point in the trade.
| Term | When you calculate it | What it measures |
|---|---|---|
| Risk-reward ratio | Before entering, from your planned stop and target | The setup's planned payoff, not what actually happened |
| R-multiple | After the trade closes | The actual result relative to the risk you took, see what is an R-multiple |
| Expectancy | Across many closed trades | The average R a strategy produces once win rate and average result are combined, see what is expectancy |
A trade planned at 1:3 risk-reward that gets closed early at half its target only realizes about +1.5R, not the +3R the setup implied. The planned ratio and the realized R-multiple are related but rarely identical, which is exactly why logging the actual exit matters as much as the plan.
Setting a minimum ratio before you trade
Most traders set a floor, such as never taking a setup below 1:1.5 or 1:2, so that a losing streak does not require an unrealistic win rate to recover from. That threshold should match the strategy's real win rate rather than being picked arbitrarily: a mean-reversion approach with a high win rate can work with a smaller ratio, while a trend-following approach with fewer, larger wins usually needs a higher one to stay profitable overall. Reviewing planned ratio against the strategy's performance metrics, including win rate and profit factor, over a meaningful sample of trades shows whether the minimum you picked actually holds up in practice, or whether targets are consistently missed before price reaches them.
