Social Security replaces a bigger share of a small paycheck than a big one, and the claim at 62, 67, or 70 decision rewrites the number permanently. SSA builds your benefit from your highest 35 years of covered earnings, pushes the result through a progressive three-part formula with 2026 bend points of $1,286 and $7,749, then scales it by your claiming age. Enter your average annual earnings in today's dollars, your years of covered work, and the age you plan to file, and this calculator shows your monthly benefit at that age, your full retirement amount, and what each extra year of waiting adds.
Your benefit is the product of an earnings average and a claiming decision. The earnings average, AIME, uses your 35 highest years after indexing, and the shortfall rule bites quietly: work only 30 years and SSA pads the average with five zero years. The claiming decision then scales the result from 70 percent of your full benefit at 62 to 124 percent at 70. SSA data shows why the spread matters: the average retired worker received about $2,071 per month in January 2026 after the 2.8 percent COLA, while the maximum at full retirement age reached $4,152, and the gap between those figures is mostly earnings history and claiming age, in roughly equal measure.
Variables in plain terms. Earnings is your average annual pay in today's dollars, capped at the 2026 taxable wage base of $184,500. Years is your count of covered working years, and anything short of 35 leaves zero years in the average. PIA, the primary insurance amount, is the full retirement benefit before any claiming adjustment. The adjustment factor comes from SSA's actuarial rules for a full retirement age of 67: five-ninths of one percent off per month for the first 36 early months and five-twelfths beyond that, or two-thirds of one percent on for each month of delay up to 70. PIA and the final benefit are rounded down to the dime, exactly as the statute requires.
The default worker earns $60,000 across 35 years, so the AIME is $5,000 a month. The formula pays 90 percent of the first $1,286, which is $1,157.40, plus 32 percent of the remaining $3,714, which is $1,188.48, for a PIA of $2,345.80 per month at 67. Claiming at 62 cuts that to $1,642.00, a permanent 30 percent haircut, while waiting to 70 lifts it to $2,908.70. The annual difference between the earliest and latest claim is over $15,000 every year, and each of those amounts carries a COLA for life.
The same worker at 30 years of earnings sees the zero-year effect directly: the AIME drops to $4,285.71 and the PIA to $2,117.30, a loss of $228.50 per month from five missing years. Filling those years back in, even at modest pay, is worth more than most raises, because each new year replaces a zero at 100 percent of its average rather than the 32 or 15 percent marginal rate the formula charges high brackets.
| Claiming age | Share of PIA | Monthly benefit | vs. age 62 |
|---|---|---|---|
| 62 | 70.0% | $1,642.00 | — |
| 63 | 75.0% | $1,759.30 | +$117.30 |
| 64 | 80.0% | $1,876.60 | +$234.60 |
| 65 | 86.7% | $2,033.00 | +$391.00 |
| 66 | 93.3% | $2,189.40 | +$547.40 |
| 67 (FRA) | 100.0% | $2,345.80 | +$703.80 |
| 68 | 108.0% | $2,533.40 | +$891.40 |
| 69 | 116.0% | $2,721.10 | +$1,079.10 |
| 70 | 124.0% | $2,908.70 | +$1,266.70 |
The table holds the default earnings profile fixed and moves only the claiming age. Notice the asymmetry: the step from 62 to 63 is worth $117.30 a month, the largest single-year jump in the early range, because the early reduction factors apply month by month rather than in flat yearly blocks. After full retirement age the increase runs at a steady 8 percent per year, so 67 to 70 adds exactly 24 percent.
Cumulative benefits make the trade concrete. Claiming at 62 on the default profile pays $1,642.00 every month starting immediately; waiting to 67 pays $2,345.80 but starts five years later. The two paths deliver equal lifetime totals at 200 months past age 62, which is age 78.7. Against a 70 claim the tie comes at about age 80.4. SSA's period life tables put a 65-year-old man's life expectancy near 85, so a retiree with average health who lives past the break-even comes out ahead by waiting, and the excess compounds for every year beyond it.
Break-even math ignores two things that tilt further toward delay. Future COLAs apply to a larger base when you claim higher, so the dollar gap widens each year. And a higher benefit follows the survivor: when the higher earner dies, the surviving spouse steps up to the deceased's amount, so delaying is partly a life-insurance purchase for the household. Claiming early wins when health is clearly poor, when you need the income to stop working, or when the money lets investments recover in a downturn instead of selling low.
First, the marginal rates are steeply progressive. Earnings inside the first bracket, up to $15,432 a year at the 2026 bend point, earn a 90 percent replacement; inside the second bracket each extra $1,000 of annual earnings adds about $26.67 to the monthly benefit; above $92,988 the marginal rate drops to 15 percent. This is why two workers with $60,000 and $90,000 salaries, 35 years each, land at $2,345.80 and $3,145.80: the extra $30,000 only bought $800 a month.
Second, the taxable maximum caps the input. Earnings above $184,500 in 2026 contribute nothing to Social Security, so the calculator's wage-base cap is doing real work, not decoration. A $250,000 salary and a $184,500 salary produce the identical $4,369.40 PIA in this model, and SSA's official maximum of $4,152 sits slightly below that because SSA indexes each historical year against wage growth, which caps past years at lower real amounts than a flat today's-dollars history does. The difference is the main reason high earners should treat this estimate as a ceiling.
The benefit estimate is one leg of a retirement plan. The retirement withdrawal calculator shows how much your portfolio can support once benefits start, and the 401k match calculator covers the accumulation side while you are still working. Because the claiming decision interacts with account sequencing, the Roth vs Traditional IRA calculator helps decide which dollars to spend first so that a delayed claim, and its larger monthly check, stays affordable in the meantime.
It applies the same statutory formula SSA uses, the 2026 bend points of $1,286 and $7,749 with the 90, 32, and 15 percent factors, and the official claiming-age adjustments for a full retirement age of 67. The simplification is the earnings history: the calculator treats your average earnings as constant in today's dollars across 35 years, while SSA indexes your actual yearly earnings to wage growth, so high earners will see slightly generous numbers here. For an estimate built on your real earnings record, use your my Social Security account at ssa.gov, which reports the exact figures SSA will pay.
AIME, average indexed monthly earnings, is your lifetime earnings boiled down to one monthly number: your highest 35 years of covered wages, each capped at the taxable maximum of $184,500 in 2026, divided by 420 months. PIA, primary insurance amount, is the monthly benefit that AIME produces through the progressive bend-point formula, and it is the amount you receive if you claim exactly at full retirement age. In the default example, a $60,000 salary gives an AIME of $5,000 and a PIA of $2,345.80, which is why a 32 percent flat replacement rate would produce a very different answer.
The break-even for this profile is about age 78.7 between claiming at 62 and 67, and about age 80.4 between 62 and 70. SSA's period life tables put the life expectancy of a 65-year-old man around age 85, so a typical retiree who lives to or beyond the break-even comes out ahead by waiting. Two factors push the decision beyond the math: delaying protects against longevity risk and produces a larger survivor benefit for a spouse, while claiming early makes sense when health is poor or you need the income to leave a job you cannot keep.
Yes, but the retirement earnings test applies before full retirement age. In 2026 the limit is $24,480 per year, and SSA withholds $1 of benefits for every $2 you earn above it. In the year you reach full retirement age the limit rises to $65,160, counted at $1 withheld per $3, and the test disappears entirely from your full retirement age month onward. Withheld benefits are not lost forever: at full retirement age SSA recomputes your payment upward to credit the withheld months, so the test works like a forced deferral rather than a permanent penalty.
Possibly, and the thresholds have never been indexed. If your combined income, which is adjusted gross income plus nontaxable interest plus half your Social Security benefit, stays under $25,000 single or $32,000 married filing jointly, none of the benefit is taxable. Between those floors and $34,000 or $44,000, up to half is taxable, and above them up to 85 percent is taxable. Because those cutoffs were set in 1993 and never adjusted, each year more retirees cross them. The take-home-pay calculator on this site handles the ordinary paycheck side, and this tax layer applies on top of it in retirement.
Every missing year counts as zero earnings in the 35-year average, which drags the AIME down hard. The default profile earning $60,000 for 34 years instead of 35 has a PIA of $2,300.10 rather than $2,345.80, so that one extra year of work adds $45.70 per month, about $548 a year, for life with a COLA attached. The reverse also holds: retiring two years early at 63 with 33 years of work costs two zero years. This is why the years-worked input moves the estimate as much as the salary input does for anyone with gaps in their record.
