Risk Reward Calculator: Trade Ratio and Win Rate
Find the risk-reward ratio for a trade from entry, stop loss, and target prices.
How to Use the Risk Reward Calculator
Evaluating trade setups prior to order execution prevents poor risk-adjusted entries. Follow these steps to calculate your exact trade metrics:

- Select Currency: Choose your currency unit from the dropdown selector.
- Enter Entry Price: Input your anticipated trade entry execution price.
- Enter Stop Loss Price: Input the technical price level where the setup is invalidated and the position must be closed.
- Enter Target Price: Input your profit-taking price level based on chart resistance or valuation multiples.
- Review Risk-Reward Metrics: Observe your per-share downside risk, upside potential, and the final 1:R risk-reward ratio in real time.
Why Risk-Reward Ratio Is a Pre-Trade Gatekeeper
A disciplined trading system treats the risk-reward ratio as an entry filter rather than a post-trade review. If a trade setup offers an attractive technical setup but requires a wide stop loss that yields only a 1:0.8 ratio, the trade should be rejected. Enforcing a strict minimum ratio (such as 1:2 or higher) ensures that winning trades reliably produce more profit than losing trades take away.
The Mathematical Formulas for Risk-Reward and Breakeven
The calculation engine computes trade asymmetry and required statistical win rates using standard formulas:
Reward per Share = |Target Price - Entry Price|
Risk : Reward Ratio = 1 : (Reward per Share / Risk per Share)
Breakeven Win Rate (%) = [1 / (1 + Reward Multiple)] × 100
The absolute value function ensures seamless functionality for both bullish long trades and bearish short sell trades.
Worked Example: Evaluating a Long Setup
Suppose you identify a stock consolidating at support with a planned buy entry at 100. You place a protective stop loss below support at 95 and target technical resistance at 115:
- Risk per Share: |100 - 95| = 5 per share
- Reward per Share: |115 - 100| = 15 per share
- Risk-to-Reward Ratio: 15 / 5 = 3 (Expressed as 1 : 3.00)
- Breakeven Win Rate: 1 / (1 + 3) = 25.0%
With this 1:3 ratio, you can lose 70% of your trades and still generate positive net expectancy across 100 trades, assuming disciplined trade execution.
Risk-Reward Ratio vs Required Win Rate Table
| Risk : Reward Ratio | Reward Multiple | Breakeven Win Rate | Profitability at 50% Win Rate |
|---|---|---|---|
| 1 : 1.0 | 1.0x | 50.0% | Breakeven (minus fees) |
| 1 : 1.5 | 1.5x | 40.0% | Moderate profit |
| 1 : 2.0 | 2.0x | 33.3% | Strong profit |
| 1 : 3.0 | 3.0x | 25.0% | High profit |
| 1 : 5.0 | 5.0x | 16.7% | Exceptional profit |
Avoiding Common Pitfalls in Ratio Planning
The most common mistake traders make is placing targets at arbitrary price levels solely to display an attractive 1:3 or 1:4 ratio on screen. A target set beyond major overhead supply or resistance has a low probability of being reached, causing winning trades to reverse into full losses. Always establish stops and targets based on genuine market structure and volume profiles first, then check whether the resulting ratio clears your minimum criteria.
Frequently Asked Questions
What is an ideal risk-reward ratio for active trading?
Professional traders commonly seek a minimum risk-reward ratio of 1:2 or 1:3. A 1:2 ratio means risking 1 dollar to potentially capture 2 dollars, enabling long-term profitability even with a win rate under 40%.
How do I calculate my required breakeven win rate?
The mathematical breakeven win rate is calculated as 1 divided by (1 + Reward Multiple). For a 1:3 risk-reward ratio, breakeven is 1 / (1 + 3) = 25%, meaning you only need 1 winner out of every 4 trades to break even.
Does a favorable risk-reward ratio guarantee trading profitability?
No. Risk-reward measures payoff geometry, not outcome probability. A strategy with a 1:5 ratio will still lose money if the win rate drops below 16.7% or if profit targets are placed at unrealistic price levels.
Does this calculator work for both long and short trade setups?
Yes. Because risk and reward are calculated using absolute mathematical distance from entry, the formula computes identical valid ratios whether you are buying long or selling short.
What is the difference between risk-reward ratio and stop loss percentage?
A stop loss percentage measures downside distance from entry in isolation. A risk-reward ratio compares that downside risk against your upside profit potential, providing a complete structural assessment of the trade setup.
Why should stop losses and profit targets be based on technical levels rather than arbitrary ratios?
Placing stops and targets at arbitrary price points just to force an attractive ratio creates invalid setups. Legitimate stops and targets must align with actual market support, resistance, and volatility dynamics.
