Win rate measures the percentage of trades you close profitably. While it is the most commonly cited trading statistic, it is also the most misunderstood — a high win rate does not guarantee profitability, and a low win rate does not mean failure. The calculator above computes your win rate alongside break-even thresholds and per-trade expectancy so you can see the full picture.
How to Use
| Input | What to Enter | Example |
|---|---|---|
| Winning Trades | Number of trades closed at a profit | 45 |
| Losing Trades | Number of trades closed at a loss | 55 |
| Average Win | Mean profit per winning trade | $620 |
| Average Loss | Mean loss per losing trade | $300 |
Enter your winning and losing trade counts to see your raw win rate. Adding your average win and loss amounts unlocks the break-even win rate and expectancy calculations, which reveal whether your win rate is actually sufficient to be profitable.
Formula Explained
Win Rate = (Winning Trades / Total Trades) × 100
Winning Trades is the count of closed positions that ended in profit. Only count trades that are fully closed — open positions should not be included because their outcome is uncertain. Most traders accumulate 50-200 trades before their win rate stabilizes into a reliable metric.
Total Trades is the sum of winning and losing trades. Some traders exclude break-even trades from both columns; others count them as losses. The key is consistency — pick one method and stick with it across all your tracking.
The formula itself is simple division, but the insight comes from pairing it with your risk-reward ratio. A trader with a 40% win rate and 3:1 average reward-to-risk is far more profitable than a trader with a 70% win rate and 0.5:1 reward-to-risk. This is why the calculator also computes break-even win rate using the formula: Break-Even Win Rate = Average Loss / (Average Win + Average Loss).
Example Calculations
Scenario 1: Swing Trader with 45% Win Rate
- Winning Trades: 45
- Losing Trades: 55
- Average Win: $620
- Average Loss: $300
- Win Rate: 45%
- Break-Even Win Rate: $300 / ($620 + $300) = 32.6%
- Expectancy: (0.45 × $620) - (0.55 × $300) = $279 - $166 = +$113 per trade
Despite winning fewer than half the time, this trader is comfortably profitable because their average winner is more than double their average loser. Their win rate exceeds the 32.6% break-even threshold by over 12 percentage points.
Scenario 2: Scalper with 78% Win Rate
- Winning Trades: 78
- Losing Trades: 22
- Average Win: $85
- Average Loss: $280
- Win Rate: 78%
- Break-Even Win Rate: $280 / ($85 + $280) = 76.7%
- Expectancy: (0.78 × $85) - (0.22 × $280) = $66.30 - $61.60 = +$4.70 per trade
This high win rate is deceptive. The trader barely clears the 76.7% break-even threshold, leaving almost no margin for error. A short losing streak could push this strategy into negative expectancy. This is common in scalping strategies where winners are small and losses are several multiples larger.
Scenario 3: Trend Follower with 30% Win Rate
- Winning Trades: 30
- Losing Trades: 70
- Average Win: $1,400
- Average Loss: $350
- Win Rate: 30%
- Break-Even Win Rate: $350 / ($1,400 + $350) = 20%
- Expectancy: (0.30 × $1,400) - (0.70 × $350) = $420 - $245 = +$175 per trade
Losing on 70% of trades looks alarming in isolation. But with a 4:1 reward-to-risk ratio, this trader only needs to win 20% of the time to break even. Their actual 30% win rate delivers strong positive expectancy — this is how many successful trend-following systems operate.
When to Use Win Rate Calculator
- After a sample of 50+ trades to get a statistically meaningful win rate rather than relying on a handful of results
- When evaluating a new strategy to determine if its win rate and R:R combination produces positive expectancy before committing real capital
- During monthly performance reviews to track whether your win rate is stable, improving, or degrading over time
- When comparing setup types — calculate win rate separately for each pattern or strategy in your journal to identify your highest-probability setups
- Before adjusting your approach to understand whether poor results stem from low win rate (entry timing) or poor risk-reward (exit management)
Tracking win rate by setup type is one of the most valuable exercises in a trading journal. A blended 50% win rate might hide the fact that your breakout trades win 65% of the time while your reversal trades win only 30%. This breakdown helps you allocate more capital to your strongest setups.

Frequently Asked Questions
What is a good win rate for trading?
There is no universally good win rate. A 30% win rate is profitable if average winners are 3-4 times larger than average losers. A 70% win rate can still lose money if losses dwarf gains. Focus on the combination of win rate and risk-reward ratio, not win rate alone.
How do you calculate win rate in trading?
Divide the number of winning trades by the total number of closed trades, then multiply by 100. For example, 40 wins out of 100 trades equals a 40% win rate. Only count fully closed positions — exclude open trades.
What win rate do you need to break even?
The break-even win rate depends on your risk-reward ratio. At 1:1 R:R you need 50%, at 1:2 R:R you need 33.3%, and at 1:3 R:R you need only 25%. The formula is Break-Even Win Rate = 1 / (1 + Reward/Risk).
Why is win rate misleading for traders?
Win rate only measures how often you win, not how much you win or lose. A trader winning 80% of trades can still blow up if a few large losses wipe out many small gains. Expectancy, which combines win rate with average win and loss size, is the true measure of edge.
How can I improve my trading win rate?
Filter setups more strictly, trade only at high-probability levels, and use a trading journal to identify which setup types have the highest win rates. Track win rate by strategy and timeframe to focus on what works best, and review your drawdown patterns to spot when your win rate drops.
