Calculate a tennis match, set, or game win percentage, or reverse-solve wins or total played from the selected record type.
Tennis Match Win Percentage Formula or Method
Win percentage is wins divided by wins plus losses, with matches, sets, and games treated as separate record scopes.
How the Calculation Works
The selected relationship is rearranged for the requested result. The requested output field is hidden, disabled, cleared, and made non-required so only the source inputs remain visible.
How to Use This Calculator
- Select the result you want in the Solve for menu.
- Enter only the visible source values from one consistent sample.
- Select Calculate and review the answer and substituted steps.
- Use Reset before starting a different sample.
Worked Example
Winning 18 sets and losing 6 gives 18 ÷ (18 + 6) × 100 = 75.00%.

Common Questions
Why did an input disappear when I changed Solve for?
