America Has a $4 Trillion Retirement Savings Gap. At 63, His Social Security Estimate May Still Be Counting Salary He Will Never Earn

A 63-year-old software project manager earning $90,000 decides his most recent paycheck was his last. He plans to wait until 67 to claim Social Security, and his online account shows a benefit estimate for that date. He treats the number as money already earned. Buried in that figure is an assumption he never made: that he will keep collecting a paycheck at his current salary for four more years.

Similar scenarios appear routinely in retirement forums. Someone in their early sixties stops work, opens Social Security’s estimator, changes expected future earnings to zero, and watches the benefit estimate drop by a couple hundred dollars a month. The calculator had been forecasting income they no longer plan to earn.

The stakes are real. TIAA has described roughly a $4 trillion gap between what Americans need for retirement and what they have saved. The U.S. personal saving rate stood at 3% in July 2026, down from 6.4% in January 2024, leaving less cushion for surprises.

Why the Estimate Assumes You Are Still Working

Social Security knows only what has been posted to your earnings record. When it shows a projected benefit at 67 or 70, it guesses what happens between now and then. Its assumption: you keep earning what you have been earning. That works for a 63-year-old staying at the same job. It overstates the check for one who has already left.

The benefit is calculated from your highest 35 years of indexed earnings. Missing years count as zeros. If you have 35 solid years, four more years of six-figure income might replace weaker years from early in your career. Remove those projected years and the low years stay in the average. Someone with gaps or thin early years can see a meaningful drop.

Stopping Work and Claiming Are Two Different Decisions

He can stop working at 63 and delay claiming until 67 or 70. Delayed retirement credits accrue after full retirement age (FRA), worth 8% per year up to 70. They apply to the benefit his actual record supports, not projected future salary. The age-70 number will be higher than age-67, but both may sit lower than the account first showed.

Example: if the current estimate at 67 is $2,800 a month and zeroing out expected future income drops it to $2,600, that is $200 a month or $2,400 a year for life. Over a 25-year retirement, that is roughly $60,000 before cost-of-living adjustments. The 2027 COLA is currently tracking near the mid-3% range, which compounds the gap further.

Run the Estimate Twice, Then Look Backward

The following exercise takes about 10 minutes inside the my Social Security account and you will likely find it useful:

1. Open the Plan for Retirement tool and record the estimate at 67 and 70 using the income Social Security currently assumes.
2. Change expected future annual income to zero and record both figures again.
3. Run a third version with realistic part-time earnings, then compare all three.

Then scroll to the earnings history and look year by year. A missing or understated past year can drag the benefit down independently of any future-income assumption. One more working year is most valuable when it replaces a zero or weak year in the top 35.

What to Do With the Lower Number

If the revised estimate changes the plan, there is still room to respond at 63. Part-time work for a year or two can add a covered year and often replaces a weaker one. Delaying the claim to 70 still adds roughly 8% per year to whatever the record supports. Adjusting withdrawals from a 401(k) or IRA in the gap years can smooth taxes before Social Security and required minimum distributions (RMDs) arrive.
