What is Risk to Reward Ratio? Why 1:2 Isn't Always Better
TL;DR: Risk to reward ratio compares how much you stand to lose on a trade versus how much you aim to gain. A higher ratio like 1:3 sounds better on paper, but without accounting for your actual win rate, it can quietly drain your account. The two numbers only make sense together.**
What Is Risk to Reward Ratio?
Risk to reward ratio, often written as R:R, is the relationship between the maximum loss you accept on a trade and the profit you are targeting.
If you place a stop loss 20 pips away from your entry and set a take profit 40 pips away, your R:R is 1:2. You are risking one unit to potentially gain two.
The formula is straightforward:
R:R = Distance to stop loss / Distance to take profit
Or, in dollar terms:
R:R = Amount risked / Amount targeted
A 1:1 ratio means you risk the same as you hope to gain. A 1:2 means your target is twice your risk. A 1:0.5 means you are targeting less than you risk, which is where a lot of retail traders quietly leak money without realising it.
That is the definition. The problems start when traders treat a high R:R as a shortcut to profitability without thinking about what win rate the ratio actually demands.
How Win Rate and R:R Work Together: Expected Value
Expected value is the concept that ties win rate and R:R together. Without it, R:R is a number without context.
The formula:
Expected Value (EV) = (Win Rate x Average Win) - (Loss Rate x Average Loss)
Let's put real numbers in. Assume you risk $100 per trade.
Example A: 1:2 R:R, 40% win rate
- Average win: $200
- Average loss: $100
- EV = (0.40 x $200) - (0.60 x $100)
- EV = $80 - $60 = +$20 per trade
That is a profitable strategy. You lose more trades than you win, but you still come out ahead.
Example B: 1:3 R:R, 25% win rate
- Average win: $300
- Average loss: $100
- EV = (0.25 x $300) - (0.75 x $100)
- EV = $75 - $75 = $0 per trade
Before commissions and spread, this strategy breaks even. After trading costs, it is a losing strategy, despite using the "impressive" 1:3 ratio.
Example C: 1:1 R:R, 60% win rate
- Average win: $100
- Average loss: $100
- EV = (0.60 x $100) - (0.40 x $100)
- EV = $60 - $40 = +$20 per trade
Same expected value as Example A. Different ratio, different win rate, same result.
This is the core point: R:R and win rate are linked. Push one up and the other typically has to move to compensate.

Why Higher R:R Ratios Demand Lower Win Rates
When you set a take profit that is three or four times your stop loss, you are asking price to travel a much longer distance without triggering your stop. Statistically, that is harder to achieve. Markets reverse, consolidate, and react to news. The further your target sits from entry, the more things can go wrong before price gets there.
This does not mean wide targets are bad. It means they require a strategy built around high-probability entry signals that can withstand those distances, or trade management that locks in partial profits along the way.
The minimum win rate needed to break even at various R:R ratios (before costs):
- 1:1 ratio requires at least 50% win rate
- 1:2 ratio requires at least 33% win rate
- 1:3 ratio requires at least 25% win rate
- 1:4 ratio requires at least 20% win rate
Lower break-even thresholds look appealing. But in live trading, consistently achieving those targets is the challenge. A system that theoretically needs only a 25% win rate to break even still needs accurate setups, disciplined execution, and a market environment that suits the strategy.
Is There an Ideal Risk to Reward Ratio?
This is one of the most common questions traders ask, and the honest answer is: it depends on your strategy.
Scalpers who hold trades for a few minutes and exploit tight ranges often work with 1:1 or even slightly below, compensated by win rates of 60% or higher. Swing traders holding positions for days might naturally achieve 1:3 or 1:4 because price has time and space to move. Trend followers may hold for weeks with asymmetric reward profiles.
There is no universal number that works across all approaches. What matters is that your actual historical win rate, measured over a meaningful sample of trades, produces a positive expected value at whatever R:R your strategy generates.

People Also Ask: Does a 1:2 Risk Reward Ratio Guarantee Profit?
No. A 1:2 ratio is not a guarantee of anything on its own.
To be profitable at 1:2, you need to win more than one third of your trades after accounting for spread, commission, and slippage. If your actual win rate sits at 30%, you are losing money at 1:2. If it sits at 50%, you are doing well.
The ratio tells you how much you could make relative to how much you risk. It says nothing about how often you will win. Both numbers need to be measured from real trading data, not assumed.
A common mistake is setting a 1:2 target on every trade regardless of setup quality. If the market structure does not support a realistic move to that target, forcing the ratio means you are either cutting stops too tight or setting targets beyond any logical resistance level. Neither improves your edge.
Common Myths About Risk to Reward Ratio
Myth 1: "Always trade at least 1:3"
This gets repeated in forums and trading courses without qualification. A 1:3 ratio is only useful if your strategy can actually reach those targets with enough frequency. Many beginners apply a 1:3 ratio to noisy, range-bound markets and watch their take profits miss repeatedly while stop losses trigger cleanly.
Myth 2: "A high R:R means low risk"
R:R describes the shape of your trade, not the probability of each outcome. High R:R can still mean high risk if the strategy has poor win rate consistency or if you are over-leveraged on each position.
Myth 3: "R:R is the most important metric in trading"
Expected value is a more complete picture. R:R is one input into that calculation. Focusing on R:R alone while ignoring win rate, average trade frequency, and drawdown will give you an incomplete view of how a system actually performs.
Myth 4: "You should never take trades below 1:2"
Some profitable strategies operate profitably at 1:1 or even below 1:1, provided the win rate supports it. Blanket rules about minimum ratios often reflect a misunderstanding of expected value rather than genuine risk management principles.
How to Find an R:R That Matches Your Strategy
Start with your trading journal or backtest results. Look at your actual average winner and average loser over a sample of at least 50 to 100 trades. Calculate your real win rate. Then plug those numbers into the expected value formula.
If your EV is positive and consistent across different market conditions, your R:R is working whether it is 1:1 or 1:4. If EV is flat or negative, raising the ratio by moving your take profit further is not the solution. The problem is usually in setup quality, trade timing, or both.
From there, use your R:R awareness at the planning stage. Before entering a trade, ask whether the distance to your target is realistic given current structure. Is there a major resistance level that price would need to break through to reach your take profit? Is the spread eating significantly into a tight risk? Those questions matter more than hitting a specific ratio number.

FAQ
What is a good risk to reward ratio for beginners? A 1:1.5 or 1:2 ratio is a reasonable starting point for beginners because it keeps the math manageable and still allows for a profitable system with a win rate below 50%. The priority should be recording real results and measuring actual performance rather than optimising the ratio before having enough data.
Can you be profitable with a 1:1 risk reward ratio? Yes, provided your win rate is above 50% after trading costs. A 60% win rate at 1:1 produces the same expected value as a 40% win rate at 1:2. Many scalping strategies operate profitably in this range.
Why does increasing my take profit not always improve my results? Moving a take profit further reduces how often price reaches it, which lowers your win rate. If the win rate drops by more than the improved ratio gains in expected value, the change makes things worse, not better. This is why testing any adjustment across a proper sample of trades matters before committing to it live.
What is expected value in trading and why does it matter? Expected value is the average result per trade across a large number of trades, accounting for both win rate and the size of wins and losses. A strategy with positive EV will be profitable over time even if individual trades lose. Negative EV strategies lose money over time regardless of how good any single trade looks. It is the most honest measure of whether a system actually works.
Does risk reward ratio change when I move my stop loss? Yes. Moving your stop loss closer to entry tightens the ratio in your favour on paper but increases the chance of being stopped out prematurely, which reduces your win rate. Moving it further gives the trade more room but requires a proportionally larger target to maintain the same ratio. Adjusting stops should always be done based on market structure, not to manufacture a more appealing R:R number.
The Bottom Line
Risk to reward ratio is a useful tool for planning trades and comparing outcomes, but it is not a standalone metric. Paired with your actual win rate, it tells you whether a strategy has positive expected value. On its own, it tells you very little.
A 1:2 ratio is not automatically better than 1:1. A 1:3 ratio is not a mark of a more sophisticated trader. What matters is whether your entries, exits, and trade management produce a positive EV over a large enough sample of trades in real market conditions.
Measure your results, calculate your expected value, and let the numbers guide your decisions. That is a more reliable foundation than chasing a ratio because someone on a forum said it was the right one.
