Win Rate Calculator

A good win rate in sports betting depends on the odds you bet at. For standard -110 bets, you need to win about 52.4% of the time just to break even. A win rate of 55% or higher at these odds is considered very good. Most long-term profitable bettors win between 53% and 58% of their bets.

A tie counts as half a win because you did not lose, but you also did not fully win. Counting it as 0.5 gives a fair middle ground. This method is used in many sports leagues and rating systems like chess Elo ratings. It keeps your win rate accurate when draws are possible.

Win rate is the percentage of total games you win. Win-loss ratio compares your wins directly to your losses. For example, 75 wins and 25 losses gives a 75% win rate but a 3:1 win-loss ratio. Win rate includes all games, while win-loss ratio ignores ties and unfinished games.

Yes. If your reward is much bigger than your risk, you can profit with a low win rate. For example, if you risk $1 to win $5, you only need to win 16.67% of the time to break even. Many successful traders and bettors win less than 50% of the time but still profit because their winners are much larger than their losers.

The more games, the more accurate your win rate. A small sample like 10 or 20 games can be misleading. Most experts suggest at least 100 games or trades before trusting your win rate. The streak analysis section of this calculator shows you confidence ranges so you can see how much your results might vary with smaller samples.

The breakeven win rate is the minimum percentage of bets or trades you must win to not lose money. It depends on your risk-to-reward ratio. If your actual win rate is higher than your breakeven rate, you are profitable. If it is lower, you are losing money over time.

The calculator uses a dynamic programming method based on probability theory. It figures out the chance that a streak of a certain length happens at least once in your set of games. It accounts for all possible spots where a streak could start, not just one specific stretch.

Yes, this is completely normal. A bettor with a 60% win rate playing 100 games has roughly a 1 in 6 chance of losing 5 or more in a row at some point. Losing streaks are a natural part of probability. The streak analysis tool helps you see exactly how likely these rough patches are.

The 68% confidence range means your actual wins will fall within that range about 68 out of 100 times. The 95% confidence range is wider and means your wins will fall within it about 95 out of 100 times. These ranges help you understand how much your results can vary from the expected average.

Yes. If you enter your wins and losses (and ties if turned on), the calculator will automatically add them up to fill in the total games. You can also enter total games and one other field, and the calculator will figure out the missing number for you.

A 1:2 risk-to-reward ratio or better is a common target. This means you risk $1 to potentially win $2, which gives a breakeven win rate of just 33.33%. The higher the reward compared to risk, the fewer wins you need to be profitable. Check the reference table in the trading section to compare different ratios.

Yes. The general win rate calculator works for any activity with wins and losses. This includes esports, video games, board games, card games, and ranked competitive matches. Just enter your wins, losses, and ties to get your stats.

The longest expected streak estimate is based on Schilling's approximation from probability theory. It uses the formula: Longest Streak ≈ log(n × (1 − p)) ÷ (−log(p)), where n is the number of games and p is your win probability. It gives a rough average, not a guarantee.

Win rate only counts how often you win, not how much you win or lose. If you win many small bets but lose a few large ones, you can have a high win rate and still lose money overall. To be profitable, your win rate must be above your breakeven win rate for the odds or risk-to-reward ratio you use.
