The number on your statement is an estimate, not a promise, and it's built on assumptions that may not match your actual plan.
Diane had been with her company for over two decades when she sat down across from Kevin Lum on a Zoom call. She'd pulled up her Social Security statement and circled a number: $3,500. "That's what I'll get if I wait until age 70, right?" she asked.
Kevin's answer surprised her. "Maybe."
That number wasn't a promise. It was an estimate built on a set of assumptions about how the rest of Diane's working life would unfold, and she was about to change two of them without realizing it would move her benefit at all.
Most people treat the figure on their Social Security statement as locked in. It isn't.
In his video Your Social Security Statement is Hiding Something, Kevin walks through the three assumptions built into every statement, and how each one can push a real benefit higher or lower than what's printed on the page. Below is that breakdown.
Why the Number on the Page Isn't the Final Answer
For most retirees, Social Security is the largest source of guaranteed income they'll have. That makes the statement's estimate one of the most heavily relied-upon numbers in a retirement plan. But the Social Security Administration doesn't know what someone's actual career will look like between now and the date they claim. So it fills in the blanks with assumptions, and those assumptions rarely match reality exactly.
There are three of them, and each one can move the number in a different direction.
1. It Assumes Current Earnings Continue Every Year Until Claiming
The statement takes the most recent year of earnings on record and carries that figure forward, as though the same income will continue every year until the benefit is claimed. But the actual benefit isn't based on one year of pay. It's based on the 35 highest-earning years of a career, adjusted for inflation, added together, and averaged.
When someone has a full 35 years of solid earnings already on the books, dropping out of the workforce a year or two early usually doesn't move the number much, since those top years are already locked in. The risk shows up when there are gaps: fewer than 35 years of meaningful earnings, career breaks, or a return to school or entrepreneurship along the way. In those cases, the formula fills empty years with zeros, which pulls the average, and the benefit, down.
The fix is simple: log into ssa.gov and pull an actual earnings record rather than relying on the projected figure. The Social Security Administration's site also includes a basic calculator that allows a lower future income, including zero, to be modeled against the current estimate.
Ask: How many years of my Social Security earnings record are strong, and how many are low or missing?
2. It Assumes Retiring and Claiming Happen on the Same Date
Every age shown on a Social Security statement, 62, full retirement age, and 70, assumes continued work at current pay all the way to that date. That's why the age 70 figure looks so much larger than the age 62 figure. Two things are actually happening at once.
The first is the delay credit. Waiting to claim increases the benefit by roughly 8% for each year past full retirement age, up to about a 24% increase by age 70. Claiming early, at 62, carries a permanent reduction of around 30% compared to the full retirement age amount. That increase applies simply for waiting to claim; it does not require continuing to work.
The second is the extra years of earnings the statement assumes come with waiting. Those additional years only raise the actual benefit if they replace a low or zero-earning year inside the top 35. For someone with a full, strong earnings history, the age 70 estimate tends to hold up as long as claiming is delayed. For someone with earnings gaps, such as time spent building a business, the projected number can be propped up by years of assumed future income that never materializes.
The core misunderstanding is treating the retirement date and the claiming date as one decision. They aren't. Someone can stop working at 62 and still wait until 70 to claim, and the statement doesn't show that distinction anywhere.
Ask: Have I actually separated the question of when I'll stop working from the question of when I'll claim?
3. It Assumes No Income Is Being Earned While Collecting
The statement doesn't show the earnings test, and it catches people off guard when they plan to claim early while still working, even part-time. The rule: for anyone who claims before full retirement age and continues working, Social Security withholds a portion of benefits once earnings pass a set limit. In 2026, that limit is $24,480, and $1 is withheld for every $2 earned above it.
A worker who claims at 64 and earns $50,000 that year is $25,520 over the limit, which triggers withholding of roughly $12,760, money that simply doesn't show up in that year's payments.
Two details tend to get missed. Part-time income counts toward the limit just like full-time pay. And the withholding isn't permanent. Once full retirement age is reached, the earnings test disappears completely, any amount can be earned with no impact, and Social Security recalculates the benefit going forward to gradually credit back what was withheld. Whether all of it comes back, though, depends on how long the benefit is collected afterward.
Ask: If I claim before my full retirement age, do I have a plan for how much I might earn from work, and have I budgeted for the withholding?
What to Do With This
A Social Security statement is a strong starting point. It's rarely wildly wrong. But it's an estimate built on assumptions about a future that hasn't happened yet, not a final answer. Anyone within a few years of claiming can log into ssa.gov and use the built-in calculator to test a lower future income, a different claiming age, or an earlier stop-work date, and see how the number on the page actually moves.

The more of these that apply, the more likely the printed estimate differs from the benefit that will actually arrive.

Frequently Asked Questions About Social Security Estimate Accuracy
How Accurate Is Your Social Security Estimated Benefit?
The estimate on a Social Security statement is built on three assumptions: that current earnings continue unchanged until claiming, that the retirement date and claiming date are the same, and that no income is earned while collecting before full retirement age. For someone with a long, strong earnings history who claims after stopping work, the estimate tends to be close. For someone with earnings gaps, a retirement date earlier than their claiming date, or plans to work part-time after claiming early, the actual benefit can differ meaningfully from what's printed.
Why does my age 70 estimate look so much higher than my age 62 estimate?
Two things are combined in that gap. Waiting to claim adds a delay credit of roughly 8% per year past full retirement age, which applies regardless of continued work. The statement also assumes eight additional years of earnings at the current salary, which only raises the actual benefit if those years replace a low or zero year within the top 35 years used in the calculation.
Do I have to keep working until age 70 to get the higher age 70 benefit?
No. The delay credit that increases a benefit for waiting to claim is earned simply by not claiming yet, not by continuing to work. Someone can stop working at 62 and still wait until 70 to claim the larger amount, as long as they can cover expenses in the meantime from other sources.
What happens if I claim Social Security early and keep working?
If benefits are claimed before full retirement age and work continues, the earnings test applies. In 2026, $1 is withheld for every $2 earned above $24,480. That withholding isn't permanent: once full retirement age is reached, the earnings test ends entirely, and Social Security recalculates the benefit to gradually credit back what was withheld.
How can I check whether my own estimate is accurate?
Log into ssa.gov and review the actual year-by-year earnings record rather than relying on the summary figure alone. The site's built-in calculator also allows a lower future income or an earlier stop-work date to be modeled, showing how the age 62, full retirement age, and age 70 estimates shift based on a more realistic plan.
