The maximum Social Security benefit for a single person depends on several factors, including the age at which they retire and their lifetime earnings. Here are the maximum benefit amounts for 2023:

• If you retire at full retirement age (FRA) in 2023, your maximum benefit would be $3,627.
• If you retire at age 62 in 2023, your maximum benefit would be $2,572.
• If you retire at age 70 in 2023, your maximum benefit would be $4,555.

Its important to note that these are the maximum benefit amounts, and most people will receive less than these amounts. To qualify for the maximum benefit, a person must have at least 35 working years during which they made at least the maximum income amount for the year.
