Apa itu Nisbah Risiko/Ganjaran?
Nisbah risiko/ganjaran (R:R) membandingkan potensi kerugian vs. keuntungan.
Professional traders never enter a trade without calculating R:R first. A consistently positive R:R — even with a 40% win rate — produces profits over time.
Formula R:R
Simple formulas for any direction:
Breakeven Win Rate Table
At 1:2, you only need to win 33% of trades to break even. At 1:3, just 25%. This is why R:R matters more than win rate.
| R:R Ratio | Breakeven Win Rate | Verdict |
|---|---|---|
| 1:1 | 50.0% | Marginal — R:R < 2:1 |
| 1:1.5 | 40.0% | Marginal — R:R < 2:1 |
| 1:2 | 33.3% | Good — R:R ≥ 2:1 |
| 1:3 | 25.0% | Excellent — R:R ≥ 3:1 |
| 1:5 | 16.7% | Excellent — R:R ≥ 3:1 |
How to Use This Calculator
Set Direction & Asset
Long if bullish, Short if bearish. Pick your asset.
Enter Entry, SL, TP
Entry price, where you'll cut losses (SL), and where you'll take profits (TP).
Read Your R:R
The calculator shows your ratio, risk/reward in $ and %, and a visual bar. Aim for 1:2 minimum.
Optional: Add Size & Win Rate
Enter position size for dollar amounts. Add your estimated win rate to see Expected Value and Kelly %.
Common R:R Mistakes
Taking 1:1 trades consistently
At 1:1, you need >50% win rate just to break even. After fees, you're likely losing money.
Moving stop-loss to 'give it room'
Widening your stop after entry destroys your R:R. Plan your stop before you enter.
Setting unrealistic take-profit
A 1:10 R:R looks great on paper, but if the target is unrealistic, it's effectively 0%. Be honest about probability.
Kelly Criterion
The Kelly criterion tells you the optimal percentage of your capital to risk per trade. Most traders use half-Kelly (Kelly% ÷ 2) for safety.

What's the minimum R:R I should accept?
Most professionals use 1:2 as the minimum. Below 1:2, you need a high win rate to be profitable, which is hard to sustain.
Does R:R work for crypto?
R:R is universal — it works for crypto, stocks, forex, commodities, and any other market.
Should I always use the same R:R?
No. Different setups have different probabilities. A breakout trade might warrant 1:3, while a scalp might work at 1:1.5 with high win rate.
How does R:R relate to position sizing?
R:R determines if the trade is worth taking. Position sizing determines how much capital to allocate. Use both together: first calculate R:R, then size accordingly.
What is Expected Value?
EV = (Win Rate × Reward) − (Loss Rate × Risk). Positive EV means the trade is profitable over many repetitions.
