Break Point Conversion Calculator
Calculate your break point conversion % and, optionally, your break point save %
What is a Break Point Conversion Calculator?
A break point is a point that, if the receiver wins it, wins the game on the opponent's serve. Break point conversion is the share of those chances a player actually takes: break points won divided by break points earned, shown as a percentage.
Worked example: a player earns 10 break points in a match and wins 4 of them. Break point conversion = 4 ÷ 10 = 40%. The 6 missed chances are break points that did not turn into a break of serve.
This calculator also lets you add the other side of the same stat: break points faced and saved on your own serve. Break point save % = break points saved ÷ break points faced.

Why Break Point Conversion Matters in Tennis
Breaking serve is how most sets are decided, so break point stats show how well a player takes the moments that matter. A player can win many return points and still lose a set if they convert few of their break chances, and the reverse can also happen.
Break point conversion and save percentages are reported in ATP and WTA match statistics, usually as "break points won" out of "break points" for each player. Looking at both for a match shows who took their chances and who held under pressure.
A single match is a small sample. Percentages from a handful of break points can swing a lot, so they say more over a season or a career than over one set. Opponent quality, surface and serve strength all affect the numbers.
?Frequently Asked Questions
A break point is any point where the receiver is one point from winning the game. That includes 30-40 or 15-40 (and 0-40), and advantage to the receiver after deuce. If the receiver wins the point, the server is broken.
Divide the break points you won by the break points you had, then multiply by 100. For example, converting 3 of 7 break points is 3 ÷ 7 = 42.9%.
There is no single official benchmark. The numbers depend on the opponent, the surface and how strong the server is, and a single match has too few break points to judge from. Compare a player's figure over many matches against the same competition for a fair picture.
It is the share of break points you faced on your own serve that you saved: break points saved ÷ break points faced × 100. It is the defensive counterpart to break point conversion.
Not necessarily. Conversion only covers the points where a break point was available. A player can return well and create many chances, so look at how many break points were earned as well as how many were converted.
