What Is Average Win/Loss Ratio in Trading?
Average win/loss ratio, also called payoff ratio, compares the average size of your winning trades to the average size of your losing trades after the fact. A worked example, a breakeven win rate table, and a clear comparison against risk-reward ratio and R-multiple, two metrics it often gets confused with.

In short. The average win/loss ratio, also called the payoff ratio, divides your average profit per winning trade by your average loss per losing trade. A trader who averages $450 on winners and $200 on losers has a ratio of 2.25: winners pay more than twice what losers cost. Unlike risk-reward ratio, which is set before a trade from a planned stop and target, this number is calculated after the fact, from a series of closed trades.
What the average win/loss ratio measures
The average win/loss ratio, also known as the payoff ratio, compares the average dollar profit of your winning trades to the average dollar loss of your losing trades. According to Babypips Forexpedia, it measures the average profit per winning trade compared to the average loss per losing trade, and a higher ratio means each win earns more than each loss costs.
Because it is built from closed trades, the ratio only exists once a trader has a track record. It answers a backward-looking question: when trades work out, how much bigger are the wins than the losses that do not.
How to calculate it
Average win/loss ratio = Average profit per winning trade / Average loss per losing trade
Say 40 trades closed last month: 16 winners averaging $450 and 24 losers averaging $200. Divide $450 by $200 and the ratio is 2.25, meaning winners average 2.25 times the size of losers. Babypips uses a similar illustration: a $400 average winner against a $200 average loser produces a ratio of 2.
Important. A ratio above 1 sounds favorable, but it says nothing about how often a strategy wins. A strategy with a 2.25 payoff ratio and a 25% win rate can still lose money over time, because three losses at $200 each ($600) outweigh one win at $450. The ratio has to be read next to win rate, not instead of it, the same trade-off covered in why your win rate lies without R-multiple.
Average win/loss ratio vs risk-reward ratio vs R-multiple
| Metric | When it is calculated | What it measures |
|---|---|---|
| Risk-reward ratio | Before entry, from the planned stop and target | The planned payoff of a single setup, see what is risk-reward ratio |
| R-multiple | After a single trade closes | The actual result of one trade relative to the risk taken, see what is an R-multiple |
| Average win/loss ratio | After a series of closed trades | The aggregate size of wins versus losses across a track record, not one setup |
The three are related but answer different questions at different scopes. Risk-reward ratio is a plan for one trade. R-multiple is the realized outcome of one trade against what was planned. Average win/loss ratio steps back further, averaging the dollar size of every win and every loss across many trades, regardless of what any single trade was originally planned to do. A strategy can show disciplined, consistent risk-reward ratios on paper and still produce a messy average win/loss ratio in the journal, if winners get cut short or stops get widened after entry.
What win rate a given ratio needs to break even
Breakeven win rate = 1 / (1 + payoff ratio)
| Payoff ratio | Breakeven win rate | What it means |
|---|---|---|
| 1.0 | 50% | Wins and losses are the same size, so half of all trades need to win |
| 1.5 | 40% | Every winner is 1.5 times a loser, so a bit under half need to win |
| 2.0 | 33% | Winners are twice the size of losers, so one in three trades needs to win |
| 3.0 | 25% | Winners are three times the size of losers, so one in four trades needs to win |
These are breakeven points before costs such as spread, commission, and slippage, so the win rate actually needed to turn a profit sits a little higher in practice. The fuller picture, weighting win rate against average result in one number, is what expectancy measures directly.
Reading it from a trading journal
Calculate the ratio over a meaningful sample, at minimum around 30 closed trades, before drawing conclusions from it. A handful of trades can be skewed by one outsized winner or loser. Split the ratio by setup tag rather than looking at only one account-wide number, since one setup can carry a noticeably better payoff ratio than another under the same account. Track the trend across a rolling window instead of a single month, because a couple of unusually large wins or losses can swing a 20 to 30 trade sample considerably. Reviewing average win/loss ratio next to win rate at the same time, rather than on separate days, is exactly the pairing recommended in the monthly trading review checklist.

What Is Sortino Ratio and How Is It Different From Sharpe?
The Sortino ratio divides return above a target by downside deviation, so large winning periods are not counted as risk. This article walks through the formula on six months of journal data, shows how the most common calculation mistake nearly triples the result, and compares three strategies with the same average return that Sharpe and Sortino rank differently.
How to Calculate Sharpe Ratio for Your Trading Results
The Sharpe ratio measures return per unit of risk, but calculating it correctly requires periodic returns, the right risk-free rate, and proper annualizing. This article walks through the formula, a worked example from a trading journal, and what the ratio misses.
What Is Maximum Consecutive Losses and Why Track It?
Maximum consecutive losses counts the longest unbroken run of losing trades, not the money lost. FTMO Academy simulations and CME Group's risk management course, both fetched directly, show how likely long streaks really are and how position sizing decides whether one is survivable.
