Evaluate any trade setup before you take it — see your R:R ratio and breakeven win rate.
Enter your trade direction, entry price, stop loss, and one or more targets.

| Breakeven Win Rate | — |
| Expected Value (per 100 trades at 50% WR) | — |
| Risk % of Entry | — |
| Reward % of Entry | — |
The risk-reward ratio (R:R) compares how much you stand to lose on a trade versus how much you stand to gain. It is one of the most important metrics in trading because it tells you whether a trade setup is worth taking — before you risk any money.
A ratio of 1:2 means for every ₹1 you risk, you expect to make ₹2. A ratio of 1:3 means ₹1 risk for ₹3 potential reward. The higher the reward relative to the risk, the fewer winning trades you need to be profitable overall.
The calculator takes three price levels from your trade plan — entry, stop loss, and target — and computes the risk (distance to stop loss) and reward (distance to target). From these, it derives the R:R ratio, breakeven win rate, and expected value.
Risk = |Entry Price − Stop Loss Price|
Reward = |Target Price − Entry Price|
Risk-Reward Ratio = 1 : (Reward ÷ Risk)
Breakeven Win Rate = 1 ÷ (1 + R:R) × 100
The breakeven win rate tells you the minimum percentage of trades you must win just to break even (before costs). The lower this number, the more forgiving the setup is — you can afford to be wrong more often and still stay profitable.
Trade Direction: Long (Buy)
Entry Price: ₹250
Stop Loss: ₹240
Target Price: ₹280
Step 1 — Risk = ₹250 − ₹240 = ₹10 per share
Step 2 — Reward = ₹280 − ₹250 = ₹30 per share
Step 3 — R:R Ratio = 1 : (30 ÷ 10) = 1 : 3
Step 4 — Breakeven Win Rate = 1 ÷ (1 + 3) × 100 = 25%
This means you only need to win 1 out of every 4 trades to break even. If your actual win rate is 40–50%, you will be consistently profitable with this R:R.
Trade Direction: Short (Sell)
Entry Price: ₹500
Stop Loss: ₹515
Target Price: ₹470
Step 1 — Risk = ₹515 − ₹500 = ₹15 per share
Step 2 — Reward = ₹500 − ₹470 = ₹30 per share
Step 3 — R:R Ratio = 1 : (30 ÷ 15) = 1 : 2
Step 4 — Breakeven Win Rate = 1 ÷ (1 + 2) × 100 = 33.3%
With a 1:2 R:R, you need to win just 1 in 3 trades to break even. This is a solid short setup where even a modest win rate generates profit.
There is no single "correct" R:R — it depends on your trading style and win rate. Here is a general guideline:
The key insight: a higher R:R compensates for a lower win rate. You do not need to be right on every trade — you need your winning trades to be significantly larger than your losing trades.
Expected value (EV) tells you how much you can expect to gain or lose per trade on average, given a specific win rate. The calculator shows EV assuming a 50% win rate over 100 trades.
EV = (Win Rate × Reward) − (Loss Rate × Risk)
If your R:R is 1:2 and your win rate is 50%:
EV = (0.50 × 30) − (0.50 × 15) = 15 − 7.5 = +7.5 points per trade
A positive EV means the setup is statistically profitable over many trades. A negative EV means you will lose money over time, even if you win some trades.
Before every trade, ask yourself: "Is the potential reward worth the risk I'm taking?" If the answer is no — if the R:R is below 1:1.5 or the target isn't at a logical level — skip the trade. There will always be another setup. The best traders are not the ones who take the most trades; they are the ones who only take trades where the math is in their favour.
