Social Security credits are the foundation of your retirement benefits. In 2018, the rules for earning these credits changed, and understanding how they work is crucial for maximizing your future benefits. This guide explains the 2018 Social Security credit calculation, including earnings requirements, how credits accumulate, and how to use our calculator to determine your eligibility.
How Social Security Credits Work
Social Security credits are earned based on your work history and earnings. Each year you work and pay Social Security taxes, you earn credits toward your retirement benefits. The number of credits you accumulate determines your eligibility for benefits and the amount you receive.
In 2018, the maximum number of credits you could earn in a year was 4. This changed from previous years when the maximum was 5 credits. The earnings base also increased to $137,700.
Credit Calculation Basics
To earn credits, you must have earned wages or self-employment income that is subject to Social Security taxes. The base year for calculating credits is the year you reach your Full Retirement Age (FRA). For most people born between 1943 and 1954, the FRA is 66.
The formula for calculating credits is:
Credits = (Earnings / (2018 Earnings Base)) × 4
Where:
- Earnings = Your total wages and self-employment income for the year
- 2018 Earnings Base = $137,700
You can earn up to 4 credits per year, with each credit representing 25 years of coverage. The maximum number of credits you can earn in your lifetime is 40.
2018 Earnings Requirements
In 2018, the earnings base for Social Security credits was $137,700. This means that if you earned $137,700 or more in wages and self-employment income, you earned the maximum of 4 credits for that year.
Earnings Thresholds
The earnings thresholds for 2018 were as follows:
| Earnings Range | Credits Earned |
|---|---|
| $0 - $13,770 | 1 credit |
| $13,771 - $27,540 | 2 credits |
| $27,541 - $41,310 | 3 credits |
| $41,311 - $137,700 | 4 credits |
If you earned less than $13,770, you earned only 1 credit for the year. If you earned more than $137,700, you still earned only 4 credits, as the maximum was capped at 4 in 2018.

Example Calculation
Let's say you earned $30,000 in wages and self-employment income in 2018. Here's how the calculation works:
Credits = ($30,000 / $137,700) × 4 ≈ 0.86 × 4 ≈ 3.44
Since you can't earn a fraction of a credit, you would earn 3 credits for the year.
This means you earned 3 credits in 2018, which contributes to your total Social Security work history.
