Risk-Reward Ratio (R:R)

The Risk-Reward Ratio (R:R) is one of the most important concepts in trading risk management. It compares the amount of money a trader is willing to risk on a trade with the potential profit they aim to make.

A favorable risk-reward ratio helps traders structure trades where the potential reward is meaningfully greater than the amount being risked. However, a high R:R alone does not make a trading strategy profitable.

Risk-Reward Ratio Formula

Risk-Reward Ratio = Potential Loss ÷ Potential Profit

The ratio is usually expressed as 1:2, 1:3, 1:4, and so on.

• Risk = Entry Price − Stop-Loss Price
• Reward = Target Price − Entry Price

For short trades, the same principle applies, but the price calculations are reversed.

Example: 1:3 Risk-Reward Ratio

Suppose a trader buys a stock at ₹100 with:

• Entry Price: ₹100
• Stop-Loss: ₹95
• Take-Profit Target: ₹115

The potential risk is:

₹100 − ₹95 = ₹5

The potential reward is:

₹115 − ₹100 = ₹15

Therefore:

Risk-Reward Ratio = ₹5 : ₹15 = 1:3

This means the trader is risking ₹1 to potentially make ₹3.

Common Risk-Reward Ratios

Many traders prefer setups offering at least 1:2 or 1:3, but the appropriate ratio depends on the trading strategy, market conditions, entry quality, and probability of reaching the target.

Why Risk-Reward Ratio Matters

Risk-reward ratio is important because profitability depends on more than simply having a high win rate.

For example, with a 1:3 R:R, a trader can theoretically break even with a 25% win rate, assuming:

• every winning trade earns 3R,
• every losing trade loses 1R,
• all trades are executed exactly as planned,
• and trading costs are ignored.

Example over 100 trades:

• 25 winning trades × 3R = +75R
• 75 losing trades × 1R = −75R
• Net result = 0R

In real trading, commissions, spreads, slippage, swaps, and execution differences mean the required win rate will generally be higher than 25% to achieve a true break-even result.

Risk-Reward Examples

R:R and Position Sizing

Risk-reward ratio should not be confused with position size.

For example, if a trader has a ₹100,000 account and decides to risk 1% per trade, the maximum planned loss is:

₹100,000 × 1% = ₹1,000

If the trade has a 1:3 R:R, the planned potential reward is:

₹1,000 × 3 = ₹3,000

The position size should be calculated from the maximum acceptable loss and stop-loss distance, rather than simply choosing a position size first.

Risk-Reward Ratio Is Not a Guarantee

A high R:R does not automatically mean a trade is good.

A setup offering 1:5 R:R may still be poor if the probability of reaching the target is extremely low. Conversely, a strategy with a lower R:R can be profitable if it has a sufficiently high win rate and strong execution.

Professional traders therefore evaluate R:R together with:

• Market structure
• Trend and momentum
• Support and resistance
• Liquidity
• Entry quality
• Stop-loss placement
• Target location
• Win rate
• Trading costs
• Position sizing
• Overall market conditions

Key Takeaway

The Risk-Reward Ratio helps traders determine whether the potential reward of a trade justifies the amount of risk being taken.

A disciplined trader should define the entry, stop-loss, target, and maximum risk before entering the position.

Remember: A favorable R:R improves the mathematical structure of a trading strategy, but risk management, probability, strategy quality, and disciplined execution ultimately determine whether the system has a positive expectancy.
