What Is a Good Win Rate in Trading?

There is no single 'good' win rate — a 40% win rate can quietly outperform a 70% one, because win rate only tells you how often you are right, never how much you make when you are. This page explains why win rate alone is a vanity metric, how R-multiples and expectancy actually decide profitability, and how to size targets and stops with the free risk/reward calculator. Research and education only — not financial advice.

The honest answer to 'what is a good win rate' is that there isn't one — not as a standalone number. A win rate is only half of a two-part equation, and on its own it cannot tell you whether a system makes or loses money. A 40% win rate paired with big winners and small losers can beat a 70% win rate paired with small winners and big losers, because the number that matters is not how often you win; it is how much you make when you win versus how much you lose when you are wrong.

Why win rate alone is a vanity metric

Win rate is seductive because it feels like a report card — 'I'm right 65% of the time' sounds like skill. But it is silent on the only thing that pays your account: the size of the wins relative to the losses. You can be right 9 times out of 10 and still go broke if the tenth trade gives back everything the other nine made. This is exactly how a trader who 'never takes a loss' — holding losers until they turn — posts a gorgeous win rate right up until one position ends the account.

Traders who quote a win rate without a reward-to-risk figure are handing you a headline with the story torn out. It is the trading equivalent of saying a business is great because it makes lots of sales, while refusing to mention the price of each sale or the cost of goods.

The number that actually decides it: R-multiples

Professionals measure trades in R, where 1R is the amount you risk — the distance from your entry to your stop. A win that makes twice your risk is +2R; a loss at your stop is −1R. Once every trade is expressed in R, win rate stops being a verdict and becomes one input into the number that grades the whole system: expectancy. If R is new to you, the deeper walkthrough lives in the risk/reward ratio explainer.

Expectancy = (win rate × average win in R) − (loss rate × average loss in R). Positive expectancy means the system earns on average over many trades; negative means it bleeds, no matter how pretty a single week looks. Win rate is one term in this equation — never the equation itself.

Because R sets the math, it also sets your breakeven win rate — the share of trades you must win just to avoid losing money, before costs. The formula is 1 ÷ (1 + your reward multiple):

Reward : risk	Winner size	Breakeven win rate
1 : 2	0.5R	67%
1 : 1	1R	50%
2 : 1	2R	33%
3 : 1	3R	25%

Read that table twice. A system with 2R winners only needs to be right about a third of the time to break even. A system with 0.5R winners needs to be right two-thirds of the time. The 'good' win rate for a trade is entirely defined by the reward you are playing for — which is why the question has no answer until you name your R.

Worked example: 40% beats 70%

Take two hypothetical systems over 100 trades each. All numbers below are illustrative, not a performance claim.

System A — the 'low' win rate. Wins 40% of the time, winners run to +2R, losers are cut at −1R. Math: (40 × 2R) − (60 × 1R) = 80R − 60R = +20R. Expectancy: +0.20R per trade.
System B — the 'high' win rate. Wins 70% of the time, but winners are only +0.5R and losers run to −2R. Math: (70 × 0.5R) − (30 × 2R) = 35R − 60R = −25R. Expectancy: −0.25R per trade.

System A wins less than half its trades and grows the account. System B wins more than two-thirds of its trades and drains it. If you had judged these two on win rate alone, you would have picked the loser. That is the entire case against win rate as a headline number — and the entire case for building trades around a stop and a target you set on purpose. You can run these scenarios with your own strike, entry, and stop in the risk/reward calculator.

An honest number from our own record

Consider a cautionary figure from our published, hypothetical backtest: the raw scanner traded blind produced 161 simulated trades at a 46.6% simulated win rate — nearly a coin flip — yet a simulated profit factor of just 0.82 and an expectancy of roughly −2% per simulated trade. A near-50% win rate, and still a losing engine, because the realized winners never cleared the realized losers. The hit rate looked respectable; the R was upside-down. You can inspect that record, losers included and posted before the move, on the public record.

Red flag: any service that markets a high win rate as its headline credential — or worse, quotes a future win rate — is selling you the vanity metric. Nobody can promise a forward win rate, and a high past one tells you nothing about reward-to-risk. Ask for expectancy and profit factor over a long, timestamped sample instead.

So what should you actually aim for?

Reframe the question. Instead of 'what win rate is good,' ask: does my honest win rate clear the breakeven line for the reward-to-risk I actually trade, with margin? If you play for 2R and win 45% of the time, you have a genuine edge. If you play for 0.5R and win 60%, you are underwater. The 'good' number is always relative to your R.

Fix your R before you enter. Decide the stop and target first; that locks in the reward multiple and the breakeven win rate you must beat.
Track expectancy, not just wins. Record every trade in R and compute (win rate × avg win) − (loss rate × avg loss); the sign of that number, not the win rate, tells you if the process works.
Size so one loss is survivable. A great win rate cannot save an oversized position — get the risk per trade right first with position sizing and the position size calculator.
Judge the process over a sample. A losing streak inside a positive-expectancy system is noise; a high win rate inside a negative-expectancy one is a slow-motion blow-up.

Every card on our model desk is written this way — a trigger, TP1 and TP2 targets, a stop, and a time-stop — so the reward-to-risk is stated before the outcome is known and the win rate is never asked to carry the argument alone. Get the R right and the win rate becomes a description of your system, not a promise about it.

Common questions

What is a good win rate for a day trader?

There is no universal figure, because a 'good' win rate depends entirely on your reward-to-risk. A day trader playing for 2R only needs to win above about 33% of the time to break even; one playing for 0.5R needs above 67%. Judge your win rate against the breakeven line for the R you actually trade, not against a fixed benchmark, and always pair it with expectancy.

Can you be profitable with a 40% win rate?

Yes — that is the whole point. In a hypothetical illustration, a 40% win rate with +2R winners and −1R losers produces expectancy of (0.40 × 2R) − (0.60 × 1R) = +0.20R per trade, a winning system. Meanwhile a 70% win rate with small +0.5R winners and large −2R losers loses money. Win rate combined with average R decides profitability; win rate alone does not.

Why is win rate called a vanity metric?

Because it measures how often you are right but says nothing about how much you make when right versus lose when wrong. You can win 9 of 10 trades and still be net negative if the tenth gives back everything. A trader who quotes a win rate without a reward-to-risk figure is showing you a headline with the story removed.

What number should I track instead of win rate?

Track expectancy — (win rate × average win in R) − (loss rate × average loss in R) — and profit factor (gross wins ÷ gross losses). These fold win rate and reward-to-risk into one figure that tells you whether the system earns over many trades. Our own hypothetical backtest showed a 46.6% simulated win rate can still pair with a losing 0.82 profit factor.
