Social Security retirement and disability benefits for 2025 will start to roll out for millions of Americans as early as Tuesday and throughout January. Why it matters: Benefits increase by 2.5% and about $50 a month but it's the lowest benefit increase in recent years.

The Senate on Saturday passed the Social Security Fairness Act, a bill that would repeal provisions that reduce benefits for some retired federal workers who also get other benefits.

Because of the calendar, Social Security recipients who get Supplemental Security Income benefits get their first 2025 check on Dec. 31, 2024.
