There are 1,046 registered MLB players for the 2025 season, and the players' union has released average salary data.

In recent years, the average salary of MLB players has repeatedly set new records, reaching $4.721393 million in the 2025 season, though the players' union highlights a gradual decline in the rate of salary increases overall.

According to the Associated Press, the MLB Players Association (MLBPA) statistics indicate that the average salary for the 2025 season is $4.721393 million, marking a 1.4% rise from the prior year. Despite the total salary reaching an all-time high, the pace of growth has clearly slowed compared to 2.4% in 2024 and 7.2% in 2023.

This data, as of August 31 last year, covers a total of 1,046 players on both the official registered roster and the injured list, including salaries, incentive bonuses, and signing bonuses. However, the report mentions that the players' union's method of calculation differs from that of the league's official figures.

The league's average salary was significantly impacted by the COVID-19 pandemic, dropping sharply in 2021. Following labor agreement negotiations, the average annual salary increase has been maintained at 7.1% since 2022. The current labor agreement is expected to expire on December 1 of this year.
