Win Rate Calculator
Calculate your win rate from wins and total games, and find how many games in a row you'd need to win to reach a target win percentage.
Win rate is wins divided by total games. The second box shows how many games you'd need to win back-to-back, with no losses, to pull your overall rate up to the target.
How it works
Win rate is wins divided by total games, shown as a percent. Win 57 of 100 and you're sitting at 57%. It's the number ranked ladders and season stats live and die by.
The interesting part is the climb. If you want a higher rate, we solve for how many games you'd have to win consecutively — no losses allowed — to drag your overall percentage up to the target you enter.
The further your goal is above your current rate, the more games it takes, and losses along the way reset the math. A 100% target is impossible once you've dropped even one game, so the tool tells you rather than showing a fantasy number.
Frequently asked questions
How is the games-needed number calculated?
It assumes you win every game from now on and finds the smallest streak that lifts your overall rate to the target. It solves (wins + x) / (total + x) = target for x, then rounds up to a whole game.
Why does it say a target is impossible?
Your all-time win rate can only approach 100% once you've lost a game — it can never actually reach it, no matter how long your win streak. So any target of 100% (or your current rate or lower with room to spare) is flagged instead of faked.
Does a real losing streak change things?
Yes. The streak count assumes flawless play going forward. Every loss you take pushes the target further away, so re-run the numbers with your updated record to see where you actually stand.
