The ATP rankings operate on a rolling 52-week cycle, where a player's position is determined by the total points earned from their 19 best tournament results (or 20 if they qualify for the year-end ATP Finals).
Points are awarded based on the tournament level and the round reached, with higher-tier events offering significantly more points.
Key mechanics include:
Point Accumulation and Expiration: Points remain on a player's record for exactly 52 weeks. When a tournament is played again the following year, the points from the previous year's result drop off and are replaced by the new result's points.
Tournament Hierarchy: Grand Slams offer the most points (2,000 for a winner), followed by ATP Masters 1000 (1,000), ATP 500 (500), and ATP 250 (250) events.
Mandatory vs. Optional: The ranking structure typically includes the four Grand Slams, eight mandatory ATP Masters 1000 events, and six "best other" results from various tours.
Updates: Rankings are officially updated every Monday based on the results from the previous week.
Live Rankings: During tournaments, "live" rankings provide real-time calculations of point changes as matches conclude, though these are unofficial until the weekly update.
This system ensures that rankings reflect a player's recent form over the past year rather than their lifetime achievements, requiring consistent performance to maintain or improve a standing.
