What Is Risk-Reward Ratio? Why Every Trade Needs a Target
Before placing any trade, ask yourself two questions: how much can I lose if this goes wrong, and how much can I make if it goes right? The risk-reward ratio is the comparison between those two numbers.
If your stop-loss would cost you $100 and your profit target would earn you $200, your risk-reward ratio is 1:2. You are risking $1 to potentially make $2.
It sounds simple. But consistently choosing trades with favourable ratios is one of the most important habits that separates traders who last from those who blow up.
How to Calculate It
Risk-Reward Ratio = Potential Loss : Potential Gain
Potential Loss = Entry Price − Stop-Loss Price (for longs) Potential Gain = Take-Profit Price − Entry Price (for longs)
Example — Long BTC:
- Entry: $60,000
- Stop-loss: $58,800 (risk = $1,200)
- Take-profit: $63,600 (reward = $3,600)
- Risk-reward ratio: $1,200 : $3,600 = 1:3
For every $1 you risk on this trade, you stand to make $3.
Why Win Rate Alone Means Nothing
Most beginners focus on how often they win. Professional traders focus on how much they win when right vs how much they lose when wrong.
Here is the math:
| Win Rate | Risk:Reward | Result Over 100 Trades (risking $100 each) |
|---|---|---|
| 60% | 1:1 | +$2,000 (60 wins × $100 − 40 losses × $100) |
| 40% | 1:3 | +$8,000 (40 wins × $300 − 60 losses × $100) |
| 30% | 1:4 | +$8,000 (30 wins × $400 − 70 losses × $100) |
| 50% | 1:1 | $0 (break even before fees) |
A trader winning only 30% of trades but targeting 1:4 risk-reward makes the same as a trader winning 40% at 1:3. Win rate and risk-reward are two sides of the same coin — expected value.
Minimum Win Rate to Break Even
At different risk-reward ratios, here is the minimum win rate needed to not lose money (before fees):
| Risk:Reward | Minimum Win Rate to Break Even |
|---|---|
| 1:1 | 50% |
| 1:1.5 | 40% |
| 1:2 | 33.3% |
| 1:3 | 25% |
| 1:4 | 20% |
At 1:2, you can lose two out of every three trades and still not lose money. This is why traders who use 1:2+ ratios consistently have a much wider margin for error.
How to Apply It Before Every Trade
Before entering, identify three things:
- Entry price — where you are getting in
- Stop-loss price — where you are wrong (see stop-loss guide)
- Take-profit price — where you are taking the win (see take-profit guide)
If the ratio is below 1:1.5, seriously consider skipping the trade. Markets offer better setups if you are patient.
The mistake most traders make: They set a tight stop-loss (small risk) and a modest take-profit (small reward) — ending up with a 1:1 or even worse ratio — and wonder why they need to win most trades just to stay flat.
Risk-Reward and Position Sizing Work Together
Risk-reward tells you whether a trade is worth taking. Position sizing tells you how much to risk on it.
A trade with a 1:3 ratio does not mean you should risk 10% of your account just because the upside is high. You still apply the 1-2% risk rule, then size the position accordingly. The ratio affects expected value, not the absolute dollar amount you risk.
