Tennis Match Stats Calculator

About this calculator

Total-points-won percentage counts every point played across a tennis match — service and return points combined — and divides points won by total points played, a stat that correlates more strongly with match outcome than the final score alone, since a tight three-set match can hide a lopsided points battle and a routine-looking scoreline can hide a match that was much closer than it appeared.

Coaches and analysts use total-points-won percentage (alongside serve-points-won and return-points-won splits) because it’s one of the most reliable single predictors of who actually played the better match, independent of how the scoring system happened to bunch points into games and sets — a player can win a match while winning barely half the total points, which is a signal worth flagging for future tactics.

This calculator takes the points you won and lost across a match and returns your total-points-won percentage.
