A player can win a tournament and still fall in the rankings the following week. That isn’t a mistake: tennis rankings reward results over a moving window, and last year’s points eventually expire. Understanding that rolling calculation makes ranking swings—and the pressure to “defend” points—much easier to follow.
The basic idea: points earned over 52 weeks
The ATP and WTA each maintain separate rankings for singles and doubles. In singles, a player earns ranking points by reaching rounds at eligible tournaments. Those points count for roughly 52 weeks, then drop away when that tournament’s next edition replaces the previous one in the ranking cycle.
A player’s ranking is based on the total from a set of counting results, subject to each tour’s rules about mandatory tournaments and which results qualify. It is not simply a record of wins, titles or matches played. A runner-up finish at a major can be worth more than a title at a smaller event, while a deep run at a top tournament may matter more than several early-round wins elsewhere.
The details of the counting rules can change, and some requirements depend on a player’s status or the event. But the core principle is consistent: points from recent results are added, older points expire, and players are ordered by their current eligible total.
How many results count?
For leading players, the calculation is shaped by the Grand Slams and major tour events, alongside a limited number of other results. The ATP and WTA have different rules, and mandatory-event requirements can affect which results are included. Some events may count automatically, while other places in a player’s total are filled by their best eligible performances.
This is why playing more tournaments does not always raise a player’s ranking. If a result is outside the player’s counting set, it may not add anything. And if a player misses an event they were required to enter, a zero-point result can sometimes affect the calculation. Exemptions and other event-specific rules apply, so a player’s points breakdown is more informative than simply counting tournaments played.
Rankings are updated regularly, generally each week. The exact points total and ranking position can be checked on the ATP or WTA website, where results are listed in the player’s ranking breakdown.
How tournaments award points
Points depend on a tournament’s category and how far a player advances. At a Grand Slam, the singles champion receives 2,000 ranking points. The runner-up earns 1,300. At an ATP Masters 1000 or WTA 1000 event, the champion earns up to 1,000 points; ATP 500 and ATP 250 winners earn 500 and 250 respectively.
Players also collect points for earlier rounds, with the amount generally increasing as they progress. The precise allocation depends on the tournament and its draw. A walkover or qualifying result may also be treated under specific rules, so not every match outcome translates into points in quite the same way.
| Tournament category | Winner’s points | What the figure means |
|---|---|---|
| Grand Slam | 2,000 | A title can provide a major boost, but points are also awarded for reaching earlier rounds. |
| Masters 1000 / WTA 1000 | Up to 1,000 | These events offer substantial points and are important parts of the tour calendar. |
| ATP 500 | 500 | A title is valuable, though worth less than a major or top-tier 1000 event. |
| ATP 250 | 250 | A smaller-category title still contributes to a player’s eligible total. |
The table shows the winner’s maximum award, not what every entrant receives. A player who loses in the first round earns far fewer points than the champion, and a tournament’s draw size affects the rounds on the way to the final.
What “defending points” means
Players do not literally defend points on court. The phrase describes what happens when last year’s result is about to expire. Suppose a player won an ATP 500 event and earned 500 points. When the next edition comes around, those points leave the player’s total. If the player wins again, the new 500 replace the old 500, so the event itself produces no net gain in the total. If the player loses early, the new result may be worth much less, and the ranking can drop.
Here is a simplified example. A player has 6,000 points, including 500 from last year’s tournament. This year, the old 500 expire. If the player earns 250 points at the new edition, the updated total is 5,750, assuming nothing else changes. The player has added points this week, but still lost 250 overall because the previous result was larger.
That is why a ranking can fall even after a respectable performance. It is also why players and commentators look at a player’s upcoming “points to defend.” On the other hand, a player who had an early loss last year has fewer points due to expire and may rise with a modest improvement.
Rankings and the Race are different
The ATP and WTA also track a calendar-year points competition, commonly called the Race. Unlike the rolling ranking, the Race starts fresh at the beginning of each season and adds points earned during that calendar year. It is especially useful for following the players competing to qualify for the season-ending championships.
That means a player can be high in the Race but lower in the main ranking, or the other way around. The main ranking includes results from the previous 52-week cycle; the Race reflects only the current season. When fans ask who is “world No. 1,” they generally mean the player at the top of the rolling singles ranking, not the Race standings.
Why rankings matter beyond bragging rights
Rankings influence entry into tournaments and seeding. A strong ranking helps a player gain direct entry into larger draws and can keep the highest-ranked players apart in the early rounds. That can make a significant difference over a long season: a seeded player may avoid another leading contender until later in a tournament, though upsets can quickly change the draw.
A ranking is not a prediction of who will win a particular match. It measures results across a period, not current form alone, head-to-head history or performance on a specific surface. A player ranked outside the top 10 might be especially dangerous on clay, while a higher-ranked opponent may be returning from injury or struggling for confidence.
Protected rankings are another source of confusion. When a player misses time with a qualifying injury or other approved reason, a protected ranking may help with tournament entry after a return. It is an entry mechanism, not a way to keep earning points during an absence or to freeze the player’s actual ranking total.
Frequently Asked Questions
Do Grand Slam points count more than tour-event points?
Yes. A Grand Slam champion earns 2,000 points, compared with up to 1,000 at a Masters 1000 or WTA 1000 event. Players also receive points for reaching later rounds, so a deep major run can be valuable even without a title.
Why can a player lose ranking points after winning matches?
Points from the corresponding event a year earlier may expire at the same time. If the new result is worth fewer points than the old one, the player’s overall total can fall despite winning matches.
Are the ATP and WTA rankings calculated the same way?
They share the broad principle of awarding points for tournament results over a rolling period, but their counting rules and event requirements are not identical. Check the relevant tour’s points breakdown for a specific player.
Does the Race determine the world No. 1?
No. The Race tracks points earned during the current calendar year, while the main ranking uses the rolling 52-week cycle. The Race helps show who is in contention for the season-ending championships.
Final Thoughts
Tennis rankings are best understood as a moving points total, not a simple count of titles or recent wins. Tournament category determines the value of a result, the counting rules shape which results are included, and last year’s points eventually fall away. Once you know what a player has to replace, a surprising rise or drop often makes perfect sense.
