Risk/Reward Ratio in Trading: What It Actually Means for Your Edge
Learn what risk/reward ratio means, how to calculate it, and why a high win rate without a good R:R ratio still loses money over time.
Most traders focus on win rate. The smarter question is: what is your risk/reward ratio? A trader who wins 40% of their trades can be consistently profitable. A trader who wins 70% of their trades can consistently lose money. The difference is the R:R ratio.
What Is Risk/Reward Ratio?
The risk/reward ratio measures how much you stand to gain versus how much you stand to lose on a given trade.
R:R Ratio = Potential Profit ÷ Potential Loss
If you risk $100 to make $300, your R:R ratio is 1:3 (or simply "3R").
Use our Risk/Reward Calculator to calculate your exact R:R, break-even win rate, and expected value before entering any trade.
How to Calculate Risk/Reward
You need three prices:
- Entry price — where you enter the trade
- Stop loss price — where you exit if wrong
- Take profit price — where you exit if right
Risk = |Entry − Stop Loss|
Reward = |Take Profit − Entry|
R:R = Reward ÷ Risk
Example: Bitcoin long
- Entry: $65,000
- Stop loss: $63,700 (risk = $1,300)
- Take profit: $69,500 (reward = $4,500)
- R:R = $4,500 ÷ $1,300 = 3.46R
Break-Even Win Rate
Every R:R ratio has a minimum win rate required to be profitable. Below that, the strategy loses money over time regardless of how good it feels.
Break-Even Win Rate = 1 ÷ (1 + R:R Ratio)
| R:R Ratio | Break-Even Win Rate | |-----------|---------------------| | 1:1 | 50% | | 1:2 | 33% | | 1:3 | 25% | | 1:4 | 20% | | 1:5 | 17% |
At 1:3 R:R, you only need to win 1 in 4 trades to break even. This is the power of asymmetric risk.
Why High Win Rate Alone Is Meaningless
Consider two traders over 100 trades:
Trader A: 70% win rate, 1:0.5 R:R (risking $200 to make $100)
- 70 wins × $100 = $7,000
- 30 losses × $200 = −$6,000
- Net: +$1,000
Trader B: 40% win rate, 1:3 R:R (risking $100 to make $300)
- 40 wins × $300 = $12,000
- 60 losses × $100 = −$6,000
- Net: +$6,000
Trader B wins less than half their trades and makes 6x more money. Win rate is not the goal. Expected value is the goal.
Expected Value: The Real Metric
Expected value (EV) tells you the average profit or loss per trade over time.
EV = (Win Rate × Avg Win) − (Loss Rate × Avg Loss)
A positive EV means the strategy is profitable over a large sample. A negative EV means it will eventually lose everything, regardless of short-term results.
Example:
- Win rate: 45%
- Average win: $300 (3R on $100 risk)
- Average loss: $100
EV = (0.45 × $300) − (0.55 × $100) = $135 − $55 = +$80 per trade
Over 200 trades, this strategy generates $16,000 in expectation.
Minimum R:R Standards
| Trading Style | Minimum R:R | Rationale | |--------------|-------------|-----------| | Scalping | 1:1.5 | High frequency, fees eat into margins | | Day trading | 1:2 | Standard for directional setups | | Swing trading | 1:2.5 | Wider stops need higher reward | | Position trading | 1:3+ | Multi-week holds justify larger targets |
Never take a trade with R:R below 1:1.5. Below that threshold, fees and slippage make profitability nearly impossible.
How to Improve Your R:R
1. Move your stop loss closer If your entry is precise, a tighter stop improves R:R without changing your target. However, a stop that is too tight will be hit by normal price noise — find the structural level, not an arbitrary distance.
2. Extend your take profit Let winning trades run further. Most traders cut profits too early. Use trailing stops or scale out at multiple targets rather than closing the entire position at the first target.
3. Be selective with entries Wait for setups that naturally offer 1:2+ R:R. If the setup doesn't offer at least 2R, skip it. Not every price movement is tradeable.
4. Factor in fees Fees reduce your effective reward. A 1:2 R:R trade with 0.1% round-trip fees on a small position is closer to 1:1.9. On high-leverage trades, fees matter even more.
R:R and Position Sizing Work Together
R:R tells you whether to take the trade. Position sizing tells you how much to risk. You need both.
A 1:3 R:R trade with 5% account risk is reckless. A 1:3 R:R trade with 1% account risk is professional. The R:R ratio is only meaningful when paired with disciplined position sizing.

Summary
- R:R ratio = potential reward ÷ potential risk
- High win rate without good R:R loses money over time
- At 1:3 R:R, you only need a 25% win rate to break even
- Always calculate expected value before trading a strategy
- Minimum viable R:R: 1:1.5 for scalping, 1:2+ for swing trading
- R:R and position sizing must be calculated together
