This win rate calculator gives you your win percentage, and above all the threshold it has to beat for your series to make money. Enter your winning trades, your losing trades, your average win and your average loss: free, instant, no sign-up. Some traders write it winrate calculator, in one word, and it is the same tool.
Amounts are in your account currency. Your average win and average loss are shown in your journal statistics.
Win rate = winning trades ÷ total closed trades, as a percentage. Only closed positions count: an open position is neither a winner nor a loser. The win rate calculator does the division for you.
Divide your average win by your average loss. That ratio, and nothing else, tells you which win percentage is enough. A 2-to-1 ratio makes a 40% win rate comfortable; a 0.5 ratio makes it ruinous.
Breakeven = 1 ÷ (1 + reward-to-risk ratio). Above it your series wins, below it your series loses. That is the only honest way to read a win percentage, and it is what this winrate calculator shows next to the raw number.
The full formula: win rate = winning trades ÷ total trades. And the threshold that matters: breakeven win rate = 1 ÷ (1 + average win ÷ average loss). A win rate you never compare with that threshold means nothing at all.
Want to understand why a high win rate can hide a losing account?
Read the win rate vs profit factor guide →A win rate calculator runs one division: winning trades over closed trades. It is simple to the point of being misleading, because the number means nothing until you know what a winner earns and what a loser costs. A trader who wins 70% of the time can lose money every month, and a trader who wins 25% of the time can make a lot of it.
That is why this win rate calculator returns three numbers instead of one. The win percentage first, the one everybody quotes. The breakeven win rate next, which is the only honest yardstick: the exact rate below which your series loses money at a constant reward-to-risk ratio. And expectancy per trade last, which turns all of it back into money.
One detail that changes the numbers: only closed positions count. An open position is neither a winner nor a loser, and including it means booking a result that does not exist yet. If your journal shows a win rate that moves while you have closed nothing, it is counting open positions.
The breakeven threshold is 1 ÷ (1 + reward-to-risk ratio). Here is what it gives for the most common ratios. The right-hand column is the win percentage you have to beat just to avoid losing money, before fees and spread.
| Reward / risk ratio | Breakeven win rate | What it means |
|---|---|---|
| 0.5 : 1 | 66.7% | You have to win two out of three just to stay flat |
| 1 : 1 | 50.0% | One in two, the textbook case |
| 1.5 : 1 | 40.0% | Four winners out of ten are enough |
| 2 : 1 | 33.3% | One in three, the most widely taught ratio |
| 3 : 1 | 25.0% | One in four, typical of swing trading |
| 4 : 1 | 20.0% | One in five, and it takes nerve to hold |
| 5 : 1 | 16.7% | One in six, for long-tail strategies only |
Read the middle column as a pass mark. Above it your series makes money; below it your series loses, whatever impression your statement leaves. And keep the first line in mind: at a 0.5-to-1 ratio, meaning losses twice the size of your wins, you need 66.7% accuracy simply to break even.
Three traders who each closed a hundred trades, with very different win percentages. The winrate calculator separates them in a single line, and the ranking is not the one you would expect.
| Profile | Win rate | Reward / risk | Breakeven | Result |
|---|---|---|---|---|
| Scalper | 70% | 0.4 : 1 | 71.4% | Losing |
| Intraday | 50% | 1.2 : 1 | 45.5% | Winning |
| Swing | 30% | 4 : 1 | 20.0% | Winning |
The scalper wins seven times out of ten and loses money. The swing trader is wrong seven times out of ten and makes money. It is the shortest demonstration of why a win percentage is never read on its own, and of why a high win rate can hide a losing account.
Four classic ways to manufacture a pretty win percentage that earns nothing. The first three are counting mistakes, the fourth is a method mistake.
Not necessarily, and it runs against instinct. Widening your targets mechanically lowers the win percentage, since a further target is hit less often. But it raises the reward-to-risk ratio, so it lowers the breakeven threshold. Of those two moves, the second is the one that counts.
So the number to watch is not the win percentage, it is expectancy per trade, which this calculator shows right next to it. It answers the only question that matters: how much each of my trades earns on average. A rate falling from 45% to 38% while expectancy goes from 12 to 31 is progress, not a step back.
And if you want a third angle on the same series, the profit factor compares the sum of your wins with the sum of your losses. It says what expectancy says, as a ratio rather than in money. For sizing, the position size calculator takes over.
Win rate = number of winning trades ÷ total closed trades × 100. With 42 winners out of 100 trades, your win rate is 42%. This win rate calculator runs that division and adds the breakeven threshold, which is the part that actually matters.
There is no good win rate in the absolute, and that is the first reading mistake. A 35% rate is plenty with a 3-to-1 reward-to-risk ratio, while a 65% rate loses money if the losses are twice the size of the wins. Always compare your rate with your breakeven threshold.
It is the exact win percentage below which your series loses money, at a constant reward-to-risk ratio. It is computed as 1 ÷ (1 + average win ÷ average loss). With an average win twice the average loss it equals 33.3%: above it you make money, below it you lose.
Not necessarily. Widening your targets usually lowers the win percentage and raises expectancy, which is progress. The number to watch is expectancy per trade, which this calculator also shows: it is what each of your trades earns on average.
Yes, fully free and no sign-up. Some people search for a winrate calculator in one word, and it is the same tool. The Tradoshi app goes further by computing your win rate automatically from your imported trades, broken down by instrument, by session and by day of the week.
