Tennis Match Stats Calculator

How it is calculated

The tool adds up the points you won and lost and shows the share you won. total points = won + lost and win % = won / total × 100. Both inputs are whole counts of points across the whole match, with service and return points together, and the percentage is shown to two decimals. If both are 0 there is no result, because nothing was played. A player with 0 won points scores 0.00%, and a negative count returns no result. The tool works on point totals only, not on games or sets, so it cannot tell who won the match. It also does not split points into serve and return.

Common mistakes

• Entering games or sets instead of points. A 6-4 set is not 10 points. The fields are for the points counted in the stats sheet or the live scoring app.
• Entering the points of one set when you meant the whole match. A single-set figure can differ greatly from the match total.
• Counting points on serve only. The tool is for all points, so adding only serve points gives a figure that does not match the stat reported by the broadcasts.
• Counting tennis scores as 15, 30 and 40. Each point won counts as 1, not as 15.
• Assuming a figure above 50% means you won the match. Because points are grouped into games and sets, a player can win a match with fewer than half of the total points.
