Ssa Benefits Calculator
Your Social Security check is not a flat amount and it is not a guess: it is your average indexed monthly earnings run through a fixed formula with 2026 bend points, then adjusted for the age you claim. This Social Security benefits calculator computes your Primary Insurance Amount from your AIME and shows your monthly benefit at 62, at full retirement age, and at 70.
Quick Answer
With average indexed monthly earnings of $5,000 and a full retirement age of 67, the 2026 bend-point formula gives a Primary Insurance Amount of $2,345.80. Claiming at 62 cuts it to $1,642 a month (30% reduction); waiting until 70 raises it to $2,908 a month (24% in delayed credits). The same earnings history is worth $1,266 more per month at 70 than at 62.
- Bend points make the formula progressive. The first $1,286 of AIME is replaced at 90%, the next band at 32%, and anything above $7,749 at 15%.
- Claiming age is the biggest lever you control. 62 versus 70 moves the check by 77% on the same earnings record.
- Bend points lock at 62. The thresholds from the year you turn 62 apply even if you claim at 70.
- 35 years is the denominator. Fewer than 35 years of earnings means zeros drag the average down.
How the SSA turns your earnings into a check
The calculation runs in three stages. First, the SSA takes your 35 highest-earning years, indexes older earnings for national wage growth, and divides the total by 420 months (35 years times 12). That is your average indexed monthly earnings, or AIME. If you worked fewer than 35 years, the missing years count as zeros, which is why a late-career high earner can still have a modest AIME. Second, the AIME runs through the bend-point formula to produce the Primary Insurance Amount, the benefit payable at full retirement age. Third, the PIA is adjusted for your claiming age. The SSA’s 2026 determinations publish the exact thresholds, and the federal regulations (20 CFR Part 404) codify the computation.
Bend points: the 2026 formula
For workers first eligible in 2026, the bend points are $1,286 and $7,749. The formula replaces 90% of the first $1,286 of AIME, 32% of AIME between $1,286 and $7,749, and 15% of AIME above $7,749, then rounds down to the next dime. The percentages are fixed by law in 42 U.S.C. 415; only the dollar thresholds move with average wages each year.
| AIME slice (2026) | Replacement rate | On the $5,000 example |
|---|---|---|
| First $1,286 | 90% | $1,157.40 |
| $1,286 to $7,749 | 32% | $1,188.48 (on $3,714) |
| Above $7,749 | 15% | $0.00 |
| PIA (rounded down to dime) | $2,345.80 |
The progressivity is deliberate: a lower earner has most of their AIME in the 90% slice, so Social Security replaces a large share of their working income, while a maximum earner’s top dollars are replaced at just 15%. The Congressional Research Service primer walks through the same formula with full worked examples.
The claiming-age lever
Once the PIA is set, timing decides the check. Claim before full retirement age and the benefit is reduced by five-ninths of 1% for each of the first 36 months early, plus five-twelfths of 1% for each additional month: at 62 with an FRA of 67, that is a permanent 30% cut. Delay past FRA and delayed retirement credits add 8% per year up to age 70, for 124% of PIA. The spread on the $5,000 example is $1,642 at 62 versus $2,908 at 70. Once you have your three numbers, test them against your budget: our mortgage payment calculator prices the housing side, and our debt-to-income ratio calculator shows how fixed debt payments fit against each benefit level.
Those maximums go to workers who earned the taxable maximum every year: the 2026 taxable maximum is $184,500. Break-even math favors waiting if you live past about 80: the larger check eventually overtakes the years of forgone payments. For married couples, the higher earner’s claiming age also sets the survivor benefit, which makes delaying the higher earner’s claim one of the highest-value moves in retirement planning.
What most Social Security estimators get wrong
Most online estimators ask for your current salary and project it forward, which silently assumes 35 full years of steady earnings and ignores the bend-point structure entirely. Some apply a flat percentage of income, which misses the progressivity that defines the program. This calculator uses the actual 2026 bend-point formula on your AIME, the same computation the SSA publishes, so the PIA is real math rather than a rule of thumb. It also shows all three claiming ages side by side with lifetime totals, because the decision is always a trade between a smaller check sooner and a larger check later. If you are considering borrowing to bridge the gap years while the higher earner’s claim is delayed, our basic loan calculator prices that bridge debt so both sides of the trade carry real numbers. For the earnings-test limits that apply if you work while claiming early, the 2026 Social Security numbers reference keeps every figure in one place.
Frequently Asked Questions
About $2,345.80 a month at full retirement age under the 2026 formula: 90% of the first $1,286 ($1,157.40) plus 32% of the remaining $3,714 ($1,188.48). Claiming at 62 reduces it to $1,642; waiting until 70 raises it to $2,908.
The two dollar thresholds in the benefit formula that split your AIME into three replacement-rate bands. For 2026 they are $1,286 and $7,749. The 90%/32%/15% rates are fixed by law; the dollar amounts adjust yearly with national average wages.
It depends on birth year: 66 for those born 1943-1954, graduating by months for 1955-1959, and 67 for anyone born in 1960 or later. Your PIA is the benefit payable exactly at that age.
With a full retirement age of 67, claiming at 62 means a 30% permanent reduction: five-ninths of 1% per month for the first 36 months early, plus five-twelfths of 1% for the remaining 24 months. With an FRA of 66, the reduction at 62 is 25%.
8% per year past full retirement age, up to age 70. From an FRA of 67, waiting until 70 gives 124% of your PIA. No credits accrue after 70, so there is never a reason to delay past then.
You need 40 credits (about 10 years of work) to qualify, but the AIME divides your top 35 years of indexed earnings by 420 months. Fewer than 35 years means zeros in the average, which pulls it down. In 2026, $1,890 of earnings buys one credit, up to four per year.
Possibly. Up to 85% of benefits can be subject to federal income tax depending on your combined income, under rules the IRS explains in its Topic 423. About a dozen states also tax benefits to some degree.
$4,152 a month at full retirement age for a worker who earned the taxable maximum in every year, about $2,969 claiming at 62, and about $5,181 at 70. Very few workers hit the maximum; the average retired-worker check is far lower.
