What Is Risk Reward Ratio in Trading?
The risk reward ratio compares:
How much you are willing to lose
vs
How much you expect to gain
It is calculated as:
Reward ÷ Risk
For example:
- If you risk ₹5 per share
- And target ₹10 per share
Your risk reward ratio is:
1 : 2
This means you are risking 1 unit to potentially gain 2 units.
What Is a Good Risk Reward Ratio?
There is no “perfect” ratio, but generally:
- 1:1 → You must win 50% of trades to break even
- 1:2 → You only need ~33% win rate
- 1:3 → You only need ~25% win rate
Professional traders usually aim for at least 1:2 or better.
The higher your reward compared to risk, the lower win rate you need to remain profitable.
What Is the 1% Risk Rule?
The 1% rule means:
Never risk more than 1% of your total capital on a single trade.
If your capital is ₹1,00,000:
1% risk = ₹1,000 maximum loss per trade.
This rule protects traders from large drawdowns and emotional trading.
Our calculator automatically uses your risk percentage to determine correct position size.
How to Calculate Position Size in Stock Market
Position size is one of the most important parts of risk management.
Formula:
Risk Amount ÷ Risk per Share = Quantity
Example:
- Capital = ₹1,00,000
- Risk % = 1%
- Risk per share = ₹5
Risk amount = ₹1,000
Position size = 1,000 ÷ 5 = 200 shares
This ensures you never exceed your predefined risk.
Why Risk Management Is Important for Stock Traders
Stock markets can be volatile, especially in:
- Intraday trading
- Small-cap stocks
- Options trading
- High leverage trades
Without proper risk management:
- A few bad trades can wipe out months of gains
- Overtrading increases losses
- Emotional decisions replace strategy
A proper risk reward ratio calculator helps enforce discipline before entering a trade.
Required Win Rate Explained
Your required win rate depends on your risk reward ratio.
Formula:
1 ÷ (1 + Risk Reward Ratio)
Examples:
- RR 1:1 → 50% win rate needed
- RR 1:2 → 33% win rate needed
- RR 1:3 → 25% win rate needed
This shows why aiming for higher reward-to-risk setups improves long-term profitability.
