Many new traders believe they must win most of their trades to make money. That is a myth. Professional traders often lose half their trades, or more, and still finish the year in profit. The reason is the risk-reward ratio. It compares how much you stand to lose on a trade with how much you hope to gain. When the numbers are in your favor, you can be wrong often and still come out ahead.

This guide explains how the risk-reward ratio works, how to calculate it, and how to use it with real trades.
What Is the Risk-Reward Ratio?
The risk-reward ratio measures the potential profit of a trade against its potential loss. It is usually written as 1:2, 1:3, and so on. The first number is your risk. The second number is your reward.
A 1:2 ratio means you risk $1 to try to make $2. A 1:3 ratio means you risk $1 to try to make $3. The higher the second number, the more each winning trade pays compared with each loss.
Your risk is the distance from your entry to your stop-loss. Your reward is the distance from your entry to your profit target. That is all there is to it.
How to Calculate the Risk-Reward Ratio
The formula is simple:
Risk-Reward Ratio = Potential Reward ÷ Potential Risk
Here is a forex example. You buy EUR/USD at 1.0850. You place your stop-loss at 1.0820, which is 30 pips of risk. You set your target at 1.0910, which is 60 pips of reward. Divide 60 by 30 and you get 2. Your risk-reward ratio is 1:2.
Here is a stock example. You buy at $40 with a stop at $38 and a target at $46. Your risk is $2 per share. Your reward is $6 per share. The ratio is 1:3.

Why the Risk-Reward Ratio Matters More Than Win Rate
Here is where the risk-reward ratio becomes powerful. It tells you the win rate you need just to break even. The formula is:
Break-Even Win Rate = 1 ÷ (1 + Reward-to-Risk)
Look at how the numbers change:
| Risk-Reward Ratio | Break-Even Win Rate |
|---|---|
| 1:1 | 50% |
| 1:2 | 33% |
| 1:3 | 25% |
| 1:4 | 20% |
At a 1:2 ratio, you can lose two out of every three trades and still break even. If you win 40% of the time, you are profitable. This is why a solid risk-reward ratio takes so much pressure off your win rate.
Expectancy: Putting Win Rate and Ratio Together
Expectancy tells you what you can expect to earn, on average, per trade. The formula is:
Expectancy = (Win Rate × Average Win) − (Loss Rate × Average Loss)
Suppose you win 40% of your trades with a 1:2 risk-reward ratio. Measured in units of risk (R), your average win is 2R and your average loss is 1R.
Expectancy = (0.40 × 2) − (0.60 × 1) = 0.80 − 0.60 = +0.20R per trade
That means that for every $100 you risk, you earn about $20 on average over many trades. It is not huge, but it is positive. Over hundreds of trades, that edge adds up. The idea comes from the statistical concept of expected value.
How to Set Profit Targets That Make Sense
A ratio only helps if the target is realistic. You cannot pick a 1:5 target just because it looks good on paper. The market has to be able to reach it.
Use Key Price Levels
Place your target just before a clear support or resistance level. If a resistance zone sits only 20 pips above your entry, a 60-pip target is unlikely to work.
Measure Recent Swings
Look at how far price has typically moved in recent swings on your time frame. A target that matches those normal moves is more believable than one that assumes a giant breakout.
Use the Risk-Reward Ratio as a Filter
Some setups look good but offer a poor ratio. If the nearest realistic target only gives you 1:0.8, skip the trade. Being selective is part of the edge.
The Risk-Reward Ratio and Position Sizing
The two ideas work as a pair. Your risk-reward ratio decides how much you can win relative to your loss. Position sizing decides how large that loss is in dollars. If you risk 1% of a $10,000 account, that is $100. With a 1:2 ratio, your target profit is $200.
Set both before you enter. Then you know your best case and worst case before a single dollar is on the line.
Don’t Forget Costs
A ratio on paper is not always the ratio you get. Trading costs eat into it. The forex spread, commissions, and slippage all make your real risk a little larger and your real reward a little smaller.
Here is an example. Say your target is 20 pips and your stop is 20 pips. That looks like 1:1. But if the spread is 2 pips, you are really risking 22 pips to make 18. Your true ratio is worse than 1:1. Tight targets are hit hardest by costs.
Common Risk-Reward Ratio Mistakes
- Chasing huge ratios. A 1:10 target rarely gets hit. A ratio is only useful if price can realistically reach the target.
- Moving the stop-loss after entry. If you widen the stop, your ratio silently gets worse. Your real ratio is the one you actually trade.
- Ignoring win rate. A great ratio with a 10% win rate can still lose money. Test both numbers together.
- Cutting winners early. Taking profit at the first sign of pullback turns a 1:2 plan into a 1:0.5 result.
- Skipping the plan. Deciding your ratio on the fly leads to emotional decisions. Write your minimum ratio into your trading plan.
Emotions play a big role in the last two points. Our article on trading psychology explains why cutting winners short and letting losers run are such common habits.
What Is a Good Risk-Reward Ratio?
There is no single perfect number. Many traders aim for at least 1:2. Scalpers, who trade very short moves, often accept lower ratios with higher win rates. Trend followers often accept lower win rates with much higher ratios.
What matters is that your ratio and your win rate work together. Track your results in a journal. After 50 to 100 trades, you will know your true numbers instead of guessing.
FAQ: Risk-Reward Ratio
Is a 1:2 risk-reward ratio good? Yes, it is a widely used minimum. You only need to win about one trade in three to break even, before costs.
Can I be profitable with a 1:1 ratio? Yes, but you need a win rate above 50% once costs are included. That is harder to sustain for most beginners.
Should the ratio be the same on every trade? Not necessarily. Set a minimum, such as 1:2, and skip trades that do not meet it. Some trades will offer more.
How does the risk-reward ratio work in crypto or stocks? The math is identical. Only the units change. Measure risk and reward in price distance, then convert to dollars.
Final Thoughts
The risk-reward ratio changes how you think about trading. Instead of asking “Will this trade win?” you ask “Is the payoff worth the risk?” That shift is what separates gambling from a repeatable process. Before your next trade, measure your stop, measure your target, and check the ratio. If it does not pay enough, walk away.
