Understanding How Social Security Credits Determine Retirement Benefit Eligibility
Verified against SSA POMS as of July 20, 2026
The short answer
Social Security credits are essential for determining eligibility for retirement benefits. A person earns credits by working in a job covered by Social Security. Starting in 1978, you needed $250 in earnings to earn a credit. This amount has increased each year and is $1,890 in 2026. Annually, a maximum of four credits can be earned. To qualify for retirement benefits, 40 credits are required.
Earning Credits Before 1978
To earn Social Security credits before 1978, a person needed to earn at least $50 in wages for any calendar quarter, beginning January 1, April 1, July 1, or October 1. Alternatively, for agricultural labor, at least $100 in annual wages after 1954 and before 1978, or $50 in any calendar quarter in 1951 through 1954 was required. Additionally, self-employment earnings needed to be at least $400 annually in taxable years from 1951 through 1977. (See SSA Handbook 0212.2)
