How is first-serve percentage calculated?

First-serve percentage is first serves in divided by total first-serve attempts, which equals total service points. If you played 62 service points and landed 38 first serves, that is 38 divided by 62, or about 61 percent.

What counts as a good first-serve percentage?

On tour, a first-serve percentage in the low-to-mid 60s is strong. Going much higher can mean a server is being too cautious, while a number under 55 percent usually forces too many vulnerable second serves.

How is the double-fault rate derived?

Every first-serve fault leads to a second serve, and every second serve that misses is a double fault. Double faults equal second-serve attempts minus second serves in, divided by total service points to get the rate.

Why is second-serve percentage usually much higher?

Players take pace off the second serve to avoid double faults, so it lands in far more often. Top servers keep second serves in above 90 percent while still applying enough spin and placement to stay safe.

What is hold percentage and is it required?

Hold percentage is service games won divided by service games played. It is optional here because it depends on rally outcomes, not just landing the serve. Leave those fields blank to skip it.

The serve is the only shot in tennis a player fully controls, so its numbers reveal a lot about a match. This calculator turns three counts, total service points and first and second serves in, into the full set of standard serve statistics.

How it works

Total service points equal first-serve attempts. Every missed first serve becomes a second-serve attempt, and every missed second serve is a double fault. From that chain the tool derives every statistic:

first-serve %      = first serves in / total service points
second-serve in %  = second serves in / (first-serve faults)
double faults      = first-serve faults - second serves in
double-fault rate  = double faults / total service points

First-serve faults equal total service points minus first serves in, which is also the number of second-serve points played.

Benchmarks and example

Suppose you serve 62 points, land 38 first serves and 18 second serves. That gives a 61 percent first-serve rate, 24 second-serve attempts of which 18 landed for 75 percent, and 6 double faults, a roughly 10 percent double-fault rate that signals a shaky second serve. Tour benchmarks: elite first-serve percentage runs about 62 to 68 percent, strong second-serve landing exceeds 90 percent, and the best servers keep double faults under about 4 percent of points. Hold percentage is optional and reflects games won, since winning a service game depends on more than just landing the serve.
