Risk-Reward Calculator

Understanding Risk to Reward Ratios in Trading

The risk-to-reward ratio (R:R) measures how much money you are willing to risk on a trade relative to the expected monetary reward. Traders use this calculator when analyzing trade setups to determine if a potential trade offers enough upside to justify the downside risk.

A favorable R:R ratio allows a strategy to remain profitable overall even if less than 50% of trades end in profit. For example, maintaining a 1:2 or 1:3 risk-to-reward ratio means winning trades generate enough profit to cover multiple losing trades.

Risk Reward Formula Breakdown

Risk and reward distances are calculated from entry price to technical levels:

Risk Distance = | Entry Price - Stop Loss Price |

Reward Distance = | Take Profit Price - Entry Price |

R:R Ratio = Reward Distance / Risk Distance

• Entry Price: Price level where your position is filled.
• Stop Loss Price: Level where your trade closes automatically to cap loss.
• Take Profit Price: Target price level where your trade closes to capture gains.

Step-by-Step Worked Example

Suppose you plan a long EUR/USD position with an entry price of 1.0800, a stop loss at 1.0750, and a take profit target at 1.0950.

1. Calculate Risk Distance: | 1.0800 - 1.0750 | = 0.0050 (50 pips).
2. Calculate Reward Distance: | 1.0950 - 1.0800 | = 0.0150 (150 pips).
3. Calculate R:R Ratio: 0.0150 / 0.0050 = 3.00 (1 : 3.0 Risk-to-Reward).

This means for every $1 risked, you stand to gain $3. A 1:3 ratio requires only a 25% win rate to reach breakeven.

Common Mistakes Traders Make

• Setting unrealistic target prices just to inflate R:R: Placing take-profit levels beyond key technical support/resistance levels makes the target unlikely to hit, causing profitable trades to reverse into losses.
• Tightening stop losses artificially: Squeezing stop losses close to entry price improves calculated R:R on paper, but leads to premature stop-outs from normal market noise.
• Ignoring win rate relationship: High R:R targets (like 1:5 or 1:10) naturally experience lower win rates and longer drawdown streaks.

Frequently Asked Questions

What is a good risk-to-reward ratio for day trading?
Most professional traders aim for minimum R:R ratios between 1:1.5 and 1:3. Ratios lower than 1:1 require high win rates (above 60%) to remain profitable long-term.

Does a higher R:R ratio guarantee overall profit?
No. Profitability depends on the combination of win rate and R:R ratio (expectancy). A 1:4 R:R strategy will still lose money if win rate falls below 20%.

Should I move my target price during a live trade?
Moving target prices during live trades without technical reasons distorts your planned R:R statistics and introduces emotional bias.
