The FedEx ATP Rankings is known colloquially by fans as 'the world rankings'. For example, when Novak Djokovic is No. 1 in the FedEx ATP Rankings, he is said to be the No. 1 player in the world. Or a player who is No. 7 in the FedEx ATP Rankings is said to be a 'Top 10 player'.

The FedEx ATP Rankings is the ATP's historical objective merit-based method used for determining entry and seeding in all tournaments for both singles and doubles, except as modified for the Nitto ATP Finals.

The breakdown - for singles and doubles – will include 19 events for all players starting in 2021. *In singles, the Nitto ATP Finals is an extra event (20th) in the ranking breakdown. Top players who compete at all mandatory events will have the following breakdown:

• One (1) Nitto ATP Finals* (additional event in the ranking breakdown)
• Four (4) Grand Slams
• Eight (8) mandatory Masters 1000s
• Seven (7) ‘Best Other’ (ATP Cup, ATP 500, ATP 250, Challenger, ITF)

The top seven players in the FedEx ATP Race To Turin after the Rolex Paris Masters on 8 November qualify for the Nitto ATP Finals. If there is one current-year Grand Slam champion positioned between No. 8 and No. 20 in the Race, he qualifies in eighth place. If there are two current-year Grand Slam champions positioned between No. 8 and No. 20 in the Race, the highest-placed of those players becomes the eighth and final qualifier; the lower-placed Grand Slam champion will serve as the alternate. If there are no current-year Grand Slam champions positioned between No. 8 and No. 20, then the player at No. 8 in the Race will claim the eighth and final berth.

The Race To Turin and the Race To Milan will only count events played in 2021. A player’s year-end Race position may not coincide with his FedEx ATP Ranking.

While the 2021 Year-End FedEx ATP Rankings will continue to potentially include some results from 2020 in a player’s rankings breakdown under the 24-month rankings system due to COVID-19, the 2021 Year-End No. 1 will be based off 2021 results alone (i.e., the FedEx ATP Race To Turin) and will continue until the end of the Nitto ATP Finals. This will ensure that the No. 1 accolade accurately reflects the world’s best performer of the 2021 calendar season.

The breakdown for doubles will include 19 events for all players starting in 2021. Top players who compete at all mandatory events will have the following breakdown:

• One (1) Nitto ATP Finals
• Four (4) Grand Slams
• Eight (8) mandatory Masters 1000s
• Seven (7) ‘Best Other’ (ATP Cup, ATP 500, ATP 250, Challenger, ITF)

The top seven teams in the FedEx ATP Doubles Team Rankings after the Rolex Paris Masters on 8 November qualify for the Nitto ATP Finals. If there is one current-year Grand Slam champion positioned between No. 8 and No. 20 in the Team Rankings, that team qualifies in eighth place. If there is no current-year Grand Slam champion positioned between No. 8 and No. 20, then the team at No. 8 in the Team Rankings will claim the eighth and final berth.

A player may petition the President for an Entry Protection when he is physically injured and does not compete in any tennis event for a minimum period of six months. The written petition must be received within six months of his last tournament.

The Entry Protection shall be a position in the FedEx ATP Rankings, as determined by the player's average FedEx ATP Rankings position during the first three months of his injury. The Entry Protection shall be for entry into the main draw or qualifying competition or for special exempt consideration. The Entry Protection shall not be used for seeding purposes, Lucky Loser consideration or for entry into the Nitto ATP Finals.

The Entry Protection shall be in effect for either the first nine tournaments that the player competes in using the Entry Protection (excluding wild cards and entries as a Direct Acceptance with his current position in the ATP Rankings) or for the period up to nine months beginning with the first tennis event that the player competes in, whichever occurs first.

If a player is physically injured and does not compete in any tennis event for a period of twelve (12) months or longer, the entry protection shall be in effect for the first twelve (12) singles tournaments and the first twelve (12) doubles tournaments that the player competes in using the entry protection (excluding wild cards and entries as a direct acceptance with his current position in the FedEx ATP Rankings) or for the period up to twelve (12) months beginning with the first tennis event, including Special Events – Exhibitions, that the player competes in, whichever occurs first.

Ties. When two or more players have the same total number of points, ties shall be broken as follows:
 
1) The most total points combined from the Grand Slams, ATP Masters 1000 mandatory tournaments and Nitto ATP Finals main draws, and if still tied, then,
2) The fewest events played, counting all missed Grand Slams, ATP Masters 1000 tournaments and Nitto ATP Finals they could have played - as if played, and if still tied, then,
3) The highest number of points from one single tournament, then, if needed, the second highest, and so on.

Prize Money is the onsite prize money awarded to players advancing within the tournament. Total Financial Commitment is the tournament’s investment in the event including ATP Sanction and Marketing Fees, Onsite Prize Money and Bonus Pool Contributions, where applicable.
