How it works
A methodology for ranking ATP careers across different eras.
The problem with official rankings
The ATP ranking system has changed multiple times since 1968 — point values, tournament categories, and scoring rules have all shifted. Summing raw ATP points across eras produces misleading comparisons: a title in 2005 is worth a different number of points than the same title in 1995. There is no clean public tool for all-time cumulative career rankings in tennis. TennisRank fills that gap.
The formula
Every result in every tournament since 1990 contributes to a player's career score. Two independent factors determine how much each result is worth: the prestige of the tournament and the quality of the draw.
Prestige Points
Fixed point values assigned to each tournament tier and round — independent of the ATP's official point system and stable across eras.
| Level | Win | Final | SF | QF | R16 |
|---|---|---|---|---|---|
| Grand Slam | 2,000 | 1,200 | 720 | 360 | 180 |
| Masters 1000 | 1,000 | 600 | 360 | 180 | 90 |
| ATP 500 | 500 | 300 | 180 | 90 | — |
| ATP 250 | 250 | 150 | 90 | 45 | — |
SPS Multiplier — draw quality
The Seed Presence Score (SPS) measures how many of the world's top 8 players (by ATP ranking at tournament start) were still alive at a checkpoint round. Winning a weak draw counts less than winning a stacked one.
Checkpoint: R16 for Slams and Masters 1000 · QF for ATP 500 · SF for ATP 250
| Top-8 alive at checkpoint | Multiplier |
|---|---|
| 7–8 players | 1.00 |
| 5–6 players | 0.85 |
| 4 players | 0.70 |
| 2–3 players | 0.55 |
| 0–1 players | 0.35 |
Scope & limitations
- · Coverage starts in 1990 (better data availability, structural equivalence to modern tour)
- · Team events (Davis Cup, Laver Cup, United Cup) are excluded
- · SPS is calculated from real data from 2000 onward; pre-2000 tournaments default to 0.80
- · Surface scores reflect only tournaments played on that surface — not a separate formula
- · Data updates weekly via automated pipeline
