About the Social Security Claiming-Age Optimizer
Almost every free Social Security calculator does one of two things: it asks for a benefit amount you were supposed to already know, or it is a lead-generation form for an advisor. This one does the actual arithmetic. It wage-indexes your earnings year by year, takes the highest 35, averages them into your AIME, and runs the three-tier bend-point formula that produces your primary insurance amount — the same sequence the Social Security Administration performs.
From there it answers the only question that really matters: 62, full retirement age, or 70? Claiming early permanently reduces the benefit by five ninths of one percent for each of the first 36 early months and five twelfths of one percent beyond that; delaying past full retirement age adds eight percent a year until 70. The tool applies those exactly, shows the monthly figure at every age from 62 to 70, and computes the break-even age for each pair — the age at which waiting finally overtakes claiming early in cumulative dollars.
Every constant is bundled directly from SSA publications and dated: the full 1951–2024 average wage index series, the contribution and benefit base back to 1972, the 2026 bend points of $1,286 and $7,749, and the current earnings-test thresholds. Figures are expressed in today's dollars, the same convention SSA uses. Nothing you type leaves your browser — the entire calculation runs locally. This is education, not personalised financial advice; confirm your own record and decision with SSA or a qualified advisor.
All figures in today’s dollars. Lifetime totals assume you live to the age set above and exclude interest and taxes.
The age at which the later claim has paid out more in total than the earlier one. Live past it and waiting wins; die before it and claiming early wins.
Discounting values a dollar received at 62 above one received at 70. A higher assumed real return shifts the answer toward claiming earlier, because you could have been investing the money.
How to Use the Claiming-Age Optimizer
The single most valuable thing you can do is paste your real earnings record. Sign in to your account at ssa.gov, open your Social Security Statement, and copy the earnings table — the tool accepts it in almost any format and parses year-and-amount pairs. Everything runs in your browser; nothing is transmitted. Then set the age you want to plan to live to, because that single assumption determines which claiming age “wins” more than anything else in the model.
The Formula Nobody Explains
Your benefit is not a percentage of your final salary. It is built in four steps:
- Cap and index. Each year’s earnings are capped at that year’s taxable maximum — $184,500 in 2026, but only $25,900 in 1980 — then multiplied by the ratio of the national average wage index in the year you turn 60 to the index in the year you earned it. This converts a 1985 salary into what it represents in modern wage terms.
- Take the top 35. The highest 35 indexed years are summed and divided by 420 months. This is your AIME, the average indexed monthly earnings.
- Apply the bend points. For 2026 eligibility the formula pays 90% of the first $1,286 of AIME, 32% of the portion between $1,286 and $7,749, and 15% of anything above. The result is your primary insurance amount — the benefit you would get at exactly full retirement age.
- Adjust for when you claim. Early claiming cuts the PIA; delaying past full retirement age raises it.
Two consequences of step three are worth internalising. First, the formula is steeply progressive: the first $1,286 of monthly average earnings is replaced at 90 cents on the dollar, the last at 15. High earners get a much larger benefit in absolute terms but a much smaller replacement rate. Second, your bend points are locked at the year you turn 62 and never re-indexed, even if you claim at 70.
Why the Zeros Hurt So Much
The divisor in step two is always 35 years, whether or not you worked that long. Someone with 28 years of earnings is not averaging 28 years — they are averaging 28 real years and seven zeros, and those zeros drag the AIME down hard. This produces a counter-intuitive result that matters enormously for people who took career breaks: an extra working year is often worth far more than a raise. Replacing a zero with even a modest year of earnings adds that whole amount divided by 420 to the AIME. Once you have 35 solid years, an additional year only helps to the extent it exceeds the lowest indexed year it displaces, and the marginal value drops sharply.
Early, Full, or Late: The Actual Trade
For anyone born in 1960 or later, full retirement age is 67. Claiming at the earliest possible age of 62 applies a reduction of five ninths of one percent for each of the first 36 early months and five twelfths of one percent for each additional month — a permanent 30% cut. Waiting past 67 earns delayed retirement credits of 8% per year up to age 70, a permanent 24% increase. So the spread between the earliest and latest claim is roughly 77% more monthly income for waiting eight years.
The break-even between claiming at 62 and at 70 typically lands somewhere in the late seventies to around 80, depending on the exact numbers. That is the crux: if you expect to live meaningfully past the break-even, delaying produces more total money and, more importantly, more money in the years when you are least able to earn. If you have a shortened life expectancy, or you need the income now to avoid drawing down assets at a bad time, claiming early is entirely rational. There is no universally correct answer, which is why the break-even ages here matter more than any single recommendation.
The Married-Couple Consideration That Changes Everything
For married couples, the higher earner’s claiming decision is not really about their own lifetime — it is about the survivor benefit. When one spouse dies, the survivor keeps the larger of the two benefits, not both. A higher earner who delays to 70 is effectively buying inflation-adjusted longevity insurance for whichever spouse lives longer, and that benefit persists for as long as either of them is alive. The practical rule most planners reach for is that the higher earner delays as long as feasible while the lower earner claims earlier to provide household cash flow. A spousal benefit, meanwhile, tops the lower earner up to 50% of the higher earner’s PIA at full retirement age — and, importantly, spousal benefits earn no delayed retirement credits, so there is no reason to delay a spousal-only claim past full retirement age.
Working While Claiming, and the Myth of the Lost Money
If you claim before full retirement age and keep working, the retirement earnings test withholds $1 of benefits for every $2 earned above $24,480 in 2026. In the year you reach full retirement age, the threshold jumps to $65,160 and the withholding rate falls to $1 for every $3, and from the month you hit full retirement age it disappears entirely. The widespread belief that withheld money is confiscated is false: at full retirement age your benefit is recalculated upward to credit the months that were withheld. Over a normal lifespan much of it comes back. The earnings test is better understood as a forced deferral than a penalty — though it can still be a strong argument for simply not claiming while you are earning a full salary.
Pair this with the Retirement Savings Calculator to see how the claiming decision interacts with portfolio withdrawals, or the Inflation Calculator to understand what an inflation-adjusted benefit is really worth over thirty years.

Frequently Asked Questions
How is my Social Security benefit actually calculated?
Your annual earnings are indexed to national wage growth, the highest 35 indexed years are averaged into a monthly figure called the AIME, and a three-tier formula converts that into the primary insurance amount. For 2026 eligibility that formula pays 90 percent of the first 1,286 dollars of AIME, 32 percent of the amount between 1,286 and 7,749, and 15 percent above that. Those thresholds are called bend points and they are fixed for life at the year you turn 62.
Is it better to claim at 62 or wait until 70?
Claiming at 62 with a full retirement age of 67 permanently reduces the benefit by 30 percent; waiting until 70 raises it by 24 percent through delayed retirement credits. The break-even against claiming at 62 typically falls in the late seventies to around age 80. Beyond longevity, delaying is worth more if you are married and the higher earner, because your benefit sets the survivor benefit. This is education, not personalised advice.
Does working after 62 increase my benefit?
It can, in two ways. A year of earnings higher than the lowest of your current top 35 indexed years replaces it and raises your AIME. Separately, if you claim before full retirement age and keep working, the earnings test withholds benefits above an annual limit, but those withheld amounts are not lost. Your benefit is recomputed upward at full retirement age to account for them.
What happens if I have fewer than 35 years of earnings?
The formula always divides by 35 years regardless. Missing years enter the average as zeros, which pulls the AIME down sharply. Someone with 28 working years has seven zeros dragging their average, so additional working years often add more to the benefit than a raise would. You need 40 credits, roughly ten years of work, to qualify at all.
Are the numbers here in today's dollars or future dollars?
Today's dollars. Earnings are wage-indexed to the most recent published index year and the current bend points are applied, which is the same convention the Social Security Administration uses for its own estimates. Actual future payments will be higher in nominal terms because of cost-of-living adjustments, but the purchasing power is what the figures here represent.
