Tournament
Following the cancellation of the 2020 WTA Finals, the tournament was originally scheduled to take place at the Shenzhen Bay Sports Center in Shenzhen, China but due to travel restrictions owing to the COVID-19 pandemic in mainland China, it was announced on September 13, 2021 that the tournament would move to Guadalajara for the year. This is the first time Mexico will host the WTA Finals. The tournament will be the 50th edition of the singles event and the 45th of the doubles competition. It will be contested by eight singles players and eight doubles teams.

Qualifying
In the singles, point totals are calculated by combining point totals from sixteen tournaments (excluding ITF and WTA 125 tournaments). Of these sixteen tournaments, a player's results from the four Grand Slam events, the four WTA 1000 tournaments with 1,000 points for the winner, and (for the players who played the main draw least 2 such tournaments) the best results from two WTA 1000 tournaments with 900 points maximum must be included. In the doubles, point totals are calculated by any combination of eleven tournaments throughout the year. Unlike in the singles, this combination does not need to include results from the Grand-Slam or Premier-level tournaments.

Format
Both the singles and doubles event features eight players/teams in a round robin event, split into two groups of four. Over the first four days of competition, each player/team meets the other three players/teams in her group, with the top two in each group advancing to the semifinals. The first-placed player/team in one group meets the second-placed player/team in the other group, and vice versa. The winners of each semifinal meet in the championship match.

Round robin tie-breaking methods
The final standings are made using these methods:


 * 1) Greatest number of [match] wins.
 * 2) Greatest number of matches played.
 * 3) Head-to-head results if only two players are tied, or if three players are tied then:


 * a. If three players each have the same number of wins, a player having played less than all three matches is automatically eliminated and the player advancing to the single elimination competition is the winner of the match-up of the two remaining tied players.
 * b. Highest percentage of sets won.
 * c. Highest percentage of games won.

Prize money and points
The total prize money for the 2021 WTA Finals is US$5,000,000. The tables below are based on the updated draw sheet information. * 2 Prize money for doubles is per team.
