How do Social Security credits work?
Credits are earned with earnings, not time worked. Every $1,970 of covered earnings in 2027 buys one credit, to a maximum of four a year — so $1,970 × 4 earned in January counts the same as a full year's pay. The dollar amount rises each year with national wages. (SSA: quarter of coverage)
| Year | Earnings for one credit | For all four |
|---|---|---|
| 2022 | $1,510 | 4 credits per year max |
| 2023 | $1,640 | 4 credits per year max |
| 2024 | $1,730 | 4 credits per year max |
| 2025 | $1,810 | 4 credits per year max |
| 2026 | $1,890 | 4 credits per year max |
| 2027 | $1,970 | 4 credits per year max |
Your Social Security statement lists your credits; the calculator above projects the rest.
40 Credits for Social Security: How Fast You Can Finish
Forty credits is ten years of work at the minimum — four credits a year. A part-time job is enough: in 2027, earning four times $1,970 at any point in the year adds the full four credits, even if you work only a few months. (SSA: Social Security credits)
What the number unlocks:
- 40 credits: your own retirement benefit and premium-free Medicare Part A.
- 30–39 credits: no retirement benefit, but Part A costs $311 a month in 2026 instead of $565 (CMS 2026 premiums).
- No credits: a spouse's record can still pay spousal benefits and free Part A.
Our take: the last few credits are the best-paid work you'll ever do
If you're in your 60s with 32 to 39 credits, a year or two of part-time work unlocks a monthly benefit for life and can make Part A free. Few jobs pay that well.
