$100,000 sounds like a lot, unless it’s what you’ve earned in your lifetime.
Some people only earn a minimum of six figures during their careers, which means when it comes time to cash out and retire, they may not get paid as much in Social Security.
GOBankingRates asked some experts to do the math on what the average Social Security check would be for someone who only made $100K in their entire career.
average indexed monthly income
Ben Waterman, CEO Straboexplained that Social Security is based on your highest 35 years of earnings, adjusted for inflation.
“So a person who earned a total of $100,000 over their lifetime would have potentially earned $2,857 (per) year over 35 years, which is $238 (per month) in inflation adjusted income,” Waterman said. “They then apply a formula that replaces a high percentage of the very low income – that’s about 90% of the first layer of earnings. However, because the earning base is so small, the ultimate profit is still very modest.”
Steve Case, a financial and insurance advisor insurance herofurther stated that taking a 35 consecutive year average of what you earned each month is used to create an individual’s average indexed monthly earnings.
“When you divide $100,000 over 420 months over 35 years, you will earn an average of only $238 per month,” Case described.
Real World Translation of Benefits
Waterman applied the formula starting in 2026 and highlighted that lifetime earnings level would translate into a monthly Social Security benefit of about $200 to $250 at retirement age.
“The reason why is that the system is progressive, but it can’t magically generate income that wasn’t there, it’s a function of lifetime earnings,” Waterman explained. “If they were lower, the profits would be lower.”
Case said the Social Security program “will help low-income people but the program’s arithmetic may still be harsh for those who do not have much of a work history or total contributions.”
final answer
According to Waterman, Social Security is designed as a safety net, not a complete retirement plan or complete income replacement.
“This is especially true for people whose lifetime earnings are limited,” Waterman added. “Anyone who remains financially inactive for a long period of time will certainly need supplemental income beyond savings, family support or a needs-based program to make retirement viable.”
