Every trading strategy's results come down to two numbers: how often it wins and how much it wins compared with how much it loses. The win rate is the percentage of trades that make money. The payoff ratio, also called the reward to risk ratio of results, is the average winning trade divided by the average losing trade. Neither number means much alone. A strategy that wins 90% of the time can lose money, and one that wins only 30% of the time can be very profitable.

## Definitions

```
Win rate = Number of winning trades / Total trades
Payoff ratio = Average winning trade / Average losing trade (as a positive number)
```

## How they combine: expectancy

```
Expectancy per trade = (Win rate × Average win) - (Loss rate × Average loss)
```

**Example: A low win rate that pays**
A trend strategy wins 40% of its trades. The average win is $300 and the average loss is $150, a payoff ratio of 2. Expectancy is 0.40 times $300 minus 0.60 times $150, which is $120 minus $90, or $30 per trade. Over 200 trades, that is about $6,000 before costs. A scalping strategy that wins 75% of trades with an average win of $50 and an average loss of $200 (payoff ratio 0.25) has expectancy of 0.75 times $50 minus 0.25 times $200, which is $37.50 minus $50, or minus $12.50 per trade, despite winning three times out of four.

## The breakeven win rate

For a given payoff ratio, the win rate needed to break even (before costs) is:

```
Breakeven win rate = 1 / (1 + Payoff ratio)
```

| Payoff ratio | Breakeven win rate |
|---|---|
| 0.5 | 66.7% |
| 1.0 | 50.0% |
| 1.5 | 40.0% |
| 2.0 | 33.3% |
| 3.0 | 25.0% |

A strategy is profitable only if its actual win rate is above the breakeven rate for its payoff ratio, by enough to cover costs. See [Expectancy](https://learn.tradelabsai.com/risk/expectancy/).

## Typical profiles

| Style | Win rate | Payoff ratio | Character |
|---|---|---|---|
| Trend following | Low (30% to 45%) | High (2 or more) | Many small losses, few big wins. See [Trend Following](https://learn.tradelabsai.com/strategies/trend-following/) |
| Mean reversion | High (55% to 70%) | Below 1 to around 1 | Frequent small wins, occasional larger losses. See [Mean Reversion](https://learn.tradelabsai.com/strategies/mean-reversion/) |
| Option selling | Very high | Low | Many small gains, rare large losses. See [Theta Harvesting](https://learn.tradelabsai.com/options/theta-harvesting/) |
| Breakout trading | Lowish | Moderate to high | Many false breakouts. See [Breakout Trading](https://learn.tradelabsai.com/strategies/breakout-trading/) |

## The psychology of win rate

Low win rate strategies are hard to stick with: losing streaks are long and frequent. With a 35% win rate, the chance of 10 losses in a row somewhere in 200 trades is high. High win rate strategies feel comfortable until a large loss erases weeks of gains. Knowing your profile in advance helps you stay disciplined. See [Losing and Winning Streaks](https://learn.tradelabsai.com/risk/losing-and-winning-streaks/) and [Discipline](https://learn.tradelabsai.com/psychology/discipline/).

## Pitfalls

1. **Chasing win rate** by taking profits early and letting losers run, which shrinks the payoff ratio. See [Disposition Effect](https://learn.tradelabsai.com/psychology/disposition-effect/).
2. **Small samples:** win rates over 20 trades are very noisy. See [Sampling and Standard Error](https://learn.tradelabsai.com/math/sampling-and-standard-error/).
3. **Ignoring costs,** which reduce every win and enlarge every loss. See [Transaction Costs](https://learn.tradelabsai.com/orders/transaction-costs/).
4. **Averages hiding outliers:** one huge loss can dominate. Check the largest losses too. See [MAE and MFE](https://learn.tradelabsai.com/risk/mae-and-mfe/).

## Improving the combination

There are two ways to improve results: raise the win rate without shrinking the payoff ratio, or raise the payoff ratio without cutting the win rate too much. Better entries, such as waiting for confirmation, usually help the win rate. Better exits, such as trailing stops that let winners run, usually help the payoff ratio. Track both numbers separately in your journal so you can see which change helped.

## Frequently asked questions

### What is a good win rate in trading?

It depends on the payoff ratio. A 35% win rate can be excellent with a payoff ratio of 3; a 70% win rate can lose money with a payoff ratio of 0.3.

### How do I calculate the payoff ratio?

Divide the average winning trade by the average losing trade, using the absolute value of losses.

### What win rate do I need to break even?

One divided by one plus the payoff ratio, before costs; for a payoff ratio of 2, that is about 33%.
