Risk/Reward Ratio Explained: Why It Matters More Than Win Rate
The Number That Actually Determines Whether You Make Money
Most traders obsess over win rate. They want to be right 70%, 80%, even 90% of the time. It feels good to win. It validates their analysis. But here is the uncomfortable truth: win rate, on its own, tells you almost nothing about whether a trading strategy is profitable.
A trader who wins 40% of the time can make more money than a trader who wins 70% of the time. The difference comes down to one number: the risk/reward ratio.
This guide explains what risk/reward ratio is, why it matters more than win rate, how to calculate it before every trade, and the specific combinations of win rate and R:R that separate profitable traders from those who slowly bleed their accounts dry.
What Is Risk/Reward Ratio?
The risk/reward ratio (R:R) compares how much you stand to lose on a trade versus how much you stand to gain.
If you risk $100 to potentially make $200, your risk/reward ratio is 1:2. You are risking one unit to make two.
If you risk $100 to make $50, your ratio is 1:0.5. You are risking twice as much as you stand to gain.
The formula is:
R:R = (Entry Price - Stop Loss) / (Take Profit - Entry Price)
For a long trade where you buy at $100, set a stop loss at $95, and a take profit at $115:
R:R = ($100 - $95) / ($115 - $100) = $5 / $15 = 1:3
You are risking $5 to make $15. For every dollar at risk, you stand to gain three.
Why R:R Matters More Than Win Rate
This is where most traders get it wrong. They chase high win rates without considering how much they win versus how much they lose. Let us look at two traders to illustrate why this is a problem.
Trader A: 50% Win Rate, 1:2 R:R
Over 10 trades, risking $100 each:
- 5 losing trades: 5 x $100 = -$500
- 5 winning trades: 5 x $200 = +$1,000
- Net result: +$500
Trader A is wrong half the time and still makes money. The 1:2 R:R means every win covers two losses. That mathematical advantage compounds over time.
Trader B: 70% Win Rate, 1:0.5 R:R
Over 10 trades, risking $100 each:
- 3 losing trades: 3 x $100 = -$300
- 7 winning trades: 7 x $50 = +$350
- Net result: +$50
Trader B wins 70% of the time and barely breaks even after commissions and spreads. The low R:R means wins are tiny relative to losses. One extra loss can turn a winning month into a losing one.
The lesson is clear: a mediocre win rate with a strong R:R beats a high win rate with a poor R:R almost every time.
Win Rate and R:R Combinations: What Is Actually Profitable?
Not every combination of win rate and R:R is profitable. The table below shows which combinations make money and which do not, assuming $100 risk per trade over 100 trades.
| Win Rate | R:R 1:0.5 | R:R 1:1 | R:R 1:1.5 | R:R 1:2 | R:R 1:3 |
|---|---|---|---|---|---|
| 30% | -$5,500 | -$4,000 | -$2,500 | -$1,000 | +$2,000 |
| 40% | -$4,000 | -$2,000 | $0 | +$2,000 | +$6,000 |
| 50% | -$2,500 | $0 | +$2,500 | +$5,000 | +$10,000 |
| 60% | -$1,000 | +$2,000 | +$5,000 | +$8,000 | +$14,000 |
| 70% | +$500 | +$4,000 | +$7,500 | +$11,000 | +$18,000 |
Some important observations from this table:
- With a 1:3 R:R, you only need a 30% win rate to be profitable. You can be wrong 7 out of 10 times and still make money.
- With a 1:1 R:R, you need above 50% win rate just to break even. After commissions and slippage, you probably need 55%+ to actually profit.
- A 1:0.5 R:R is brutal. You need to win over 70% of your trades to make anything, and even then the profit is thin.
This is why professional traders focus on finding setups with favorable R:R rather than trying to be right on every trade.
How to Calculate R:R Before Every Trade
Calculating risk/reward before entering a trade is non-negotiable. If you do not know your R:R before you click the button, you are gambling.
Step 1: Identify Your Entry Price
This is where you plan to enter the trade. Whether it is a limit order at a support level or a market order on a breakout, you need a specific price.
Step 2: Set Your Stop Loss
Your stop loss should be placed at a level where your trade idea is invalidated. Not at a random distance, but at a price where the setup is no longer valid.
For a long trade, that might be below a support level, below a swing low, or below a key moving average. The stop has to make technical sense.
Step 3: Determine Your Take Profit
Your take profit should also be at a logical level. The next resistance zone, a measured move target, a Fibonacci extension, or a prior swing high.
Step 4: Calculate the Ratio
R:R = Distance to Stop Loss / Distance to Take Profit
If the distance to your stop is 40 pips and the distance to your take profit is 80 pips, your R:R is 1:2.
If the calculation shows a 1:0.8 ratio, the trade is not worth taking. Your potential reward does not justify the risk. Move on and wait for a better setup.
Minimum R:R Recommendations by Trading Style
Different trading styles call for different minimum R:R thresholds because of how frequently they trade and how much they pay in spreads and commissions.
Day Trading: Minimum 1:1.5
Day traders take many trades, which means transaction costs add up quickly. A 1:1 R:R barely covers costs. Aim for at least 1:1.5 to ensure profitability after spreads, commissions, and slippage.
Since day traders work on smaller timeframes, finding 1:1.5 setups is common if you are patient. The temptation is to take 1:1 or worse setups just to "be in the market." Resist that temptation.
Swing Trading: Minimum 1:2
Swing traders hold positions for days to weeks. They take fewer trades but use wider stops. A minimum 1:2 R:R ensures that each win meaningfully offsets losses and grows the account.
The advantage of swing trading is that larger timeframe moves tend to produce better R:R setups naturally. A pullback to a weekly support level with a stop below the level and a target at the next resistance often gives 1:2 or 1:3 ratios without forcing anything.
Position Trading: Minimum 1:3
Position traders hold for weeks to months. They take very few trades, so each one needs to count. A 1:3 R:R means you can be wrong on two out of three trades and still break even on the third.
Position trading also involves holding through significant drawdowns during the trade, which makes the higher R:R requirement a psychological necessity. Watching a trade pull back 50% of the way to your stop is easier when you know the potential reward is three times the risk.
Common R:R Mistakes
Mistake #1: Moving Your Stop Loss
This is the most common and most destructive mistake. You enter a trade with a 1:2 R:R. The trade moves against you. Instead of accepting the loss, you widen your stop to "give it more room."
Now your R:R is 1:1 or worse. You have turned a well-structured trade into a gamble. Worse, when traders widen their stop once, they tend to do it again and again until the loss is catastrophic.
If your stop loss is hit, take the loss. That is what position sizing is for.
Mistake #2: Taking Profit Too Early
The opposite problem. You enter a trade with a 1:3 R:R. The trade moves in your favor, and you are up 1R (your risk amount). The fear of giving back profits kicks in, and you close the trade early.
You just turned a 1:3 R:R into a 1:1 R:R. Do this consistently, and your win rate needs to be much higher to remain profitable. If your take profit target is logical and well-placed, let the trade run to it.
Partial profit taking (closing half at 1R and letting the rest run) is a reasonable compromise, but be aware that it changes your effective R:R.
Mistake #3: Not Calculating R:R Before Entry
Many traders enter a trade because "it looks good" and then figure out their stop and target afterward. This is backwards. The R:R should be calculated before you enter, and the trade should only be taken if the R:R meets your minimum threshold.
If you calculate the R:R after entering, you will rationalize poor setups. If you calculate it before, you will naturally filter out bad trades.
Mistake #4: Using Arbitrary R:R Targets
Setting a take profit exactly 2x your stop loss distance on every trade, regardless of market structure, is a mistake. Your take profit should be at a level where price is likely to react, not at an arbitrary multiple.
If the next resistance is only 1.2x your stop distance away, do not set your take profit at 2x and hope the market keeps running through resistance. Either accept the 1:1.2 ratio if it meets your threshold, or skip the trade.
R:R in Practice: A Complete Trade Example
You are analyzing EUR/USD on the 4-hour chart. Price has pulled back to the 1.0850 support level, which has held three times in the past month.
- Entry: 1.0855 (limit order just above support)
- Stop Loss: 1.0820 (below the support zone, 35 pips)
- Take Profit: 1.0925 (previous swing high, 70 pips)
- R:R: 35 pips / 70 pips = 1:2
The setup meets your minimum 1:2 threshold. You calculate your position size using the position size calculator based on your account size and 1% risk. You place the trade and walk away.
If the stop is hit, you lose 1%. If the target is hit, you gain 2%. Over many trades, this approach is mathematically sound.

Key Takeaways
- Risk/reward ratio measures how much you stand to gain relative to how much you risk on each trade.
- Win rate alone does not determine profitability. R:R is the other half of the equation, and often the more important half.
- A 40% win rate with a 1:2 R:R is more profitable than a 70% win rate with a 1:0.5 R:R.
- Calculate your R:R before every trade. If it does not meet your minimum threshold, do not take the trade.
- Never move your stop loss to avoid a loss. Never take profit too early out of fear. Both actions destroy your edge.
- Use our risk/reward calculator to evaluate setups objectively before entering.
