Monthly Benefit at Age 67 (Delayed)

$3,012/mo

Claiming before your full retirement age (67) locks in a permanently reduced benefit for life; waiting past it — up to 70 — permanently increases it by about 8% per year. There's no single right age: it depends on health, other income, and whether you need the cash sooner rather than maximizing the monthly amount.

How Social Security Calculator Works

PIA = 90% x AIME(up to $1,286) + 32% x AIME($1,286-$7,749) + 15% x AIME(above $7,749)

The Primary Insurance Amount (PIA) is calculated from your Average Indexed Monthly Earnings (AIME) using a progressive formula with three bend points. Benefits are then adjusted up or down based on the age you claim relative to your Full Retirement Age (FRA). All calculations use decimal.js for precision with the SSA bend point formula.

PIA
Primary Insurance Amount — The monthly benefit you would receive if you claimed exactly at your Full Retirement Age. All adjustments for early or delayed claiming are based on this number.
AIME
Average Indexed Monthly Earnings — The SSA takes your highest 35 years of indexed earnings (wage-adjusted for inflation), sums them, and divides by 420 months. If you worked fewer than 35 years, zero years are included, reducing your AIME.
FRA
Full Retirement Age — For those born 1943-1954: Age 66. For those born 1960+: Age 67. For years in between, FRA increases in 2-month increments per birth year.
+8%/yr
Delayed Retirement Credits — For every year you delay claiming past your FRA (up to age 70), your benefit increases 8% per year (0.667% per month). This is risk-free and guaranteed — the highest return available to most retirees.
Bend Points
PIA Bend Points — Bend points are the dollar thresholds in the PIA formula that determine the weighting of your AIME. For 2026, the first bend point is $1,286 (90% replacement) and the second is $7,749 (32% replacement up to this, 15% above). These are adjusted annually for average wage growth.

Source: Social Security Administration PIA formula (https://www.ssa.gov/oact/cola/piaformula.html). Bend points are for workers turning 62 in 2026: $1,286 and $7,749. The 90%-32%-15% replacement tiers are set by law. Delayed retirement credits are 8% per year (0.667% per month) for those born 1943+, applied from FRA to age 70.

Social Security replaces a higher percentage of lower earnings — the progressive bend point formula is the key to understanding your benefit

Worked Examples

Maria, born in 1965, earned $85,000/year throughout her career. How much will she receive at FRA vs. age 62 vs. age 70?

birthYear = 1965 · annualIncome = 85000 · maritalStatus = single · retirementAge = 67

At 67 (FRA): $3,012/mo. At 62: $2,108/mo (70% of FRA). At 70: $3,735/mo (124% of FRA).

Delaying from 62 to 70 increases Maria's benefit by about 77%: $2,108 vs $3,735/month. But she would give up 8 years of payments at the lower rate (8 × 12 × $2,108 ≈ $202,000 if she had claimed at 62 instead). The break-even age — the point where total lifetime benefits from delaying surpass early claiming — is about 79 for claiming at 67 instead of 62 and about 80 for claiming at 70. If Maria expects to live past that, waiting pays off. (Her AIME is $85,000 / 12 = $7,083; PIA = 0.9 × $1,286 + 0.32 × ($7,083 − $1,286) = $3,012.50.)

James, born in 1970, earns $45,000/year. What strategy maximizes his Social Security?

birthYear = 1970 · annualIncome = 45000 · maritalStatus = single · retirementAge = 62

At 62: $1,362/mo. At FRA (67): $1,945/mo. At 70: $2,412/mo.

For James, the 90% replacement tier covers most of his AIME, giving him a proportionally larger benefit relative to his income. At about a 52% replacement rate (PIA $1,945.80 ÷ monthly income $3,750), Social Security will be a major income source. Low-income workers benefit most from delaying because the 8%/year delayed credits apply to the full PIA.

A married couple, both born 1960, has one spouse earning $120,000 and the other $30,000. What claiming strategy maximizes their household income?

birthYear = 1960 · annualIncome = 120000 · maritalStatus = married · retirementAge = 70 · spouseIncome = 30000

Higher earner at 70: $4,418/mo. Lower earner's own (at FRA): $1,545/mo. Spousal benefit: up to $1,781/mo.

The lower-earning spouse receives their own benefit ($1,545/mo) plus a spousal top-up of about $236 that brings the total to 50% of the higher earner's PIA ($3,563.20), about $1,781/mo. The common strategy: higher earner delays to 70 to maximize the survivor benefit, while the lower earner claims earlier or uses spousal benefits, depending on health and financial needs.

Understanding the Result

Social Security is the most complex financial decision most Americans face. Claiming at 62 gives you money immediately but reduces your monthly payment permanently — by 25-30% compared to claiming at FRA. Waiting to 70 gives you 24-32% more than FRA. The math favors delayed claiming for anyone in good health who expects to live past their mid-to-late 70s. However, if you have health concerns, immediate cash needs, or a lower-earning spouse who depends on your benefit, early claiming may make sense.

There is no universally correct answer.

How to Use

  1. Enter your birth year — this determines your Full Retirement Age (FRA).
  2. Enter your current annual earned income. The calculator uses a simplified AIME: your income (up to the $184,500 taxable maximum) is treated as your earnings in every one of your 35 working years, in today's dollars.
  3. Use the retirement age field (62-70) to see how early or late claiming affects your monthly benefit, and review the comparison chart below.

Frequently Asked Questions

Is this an accurate Social Security estimate?
This is a simplified approximation using the SSA's bend point formula. It assumes your current income is representative of your career earnings. For the most accurate estimate, create a free account at ssa.gov/myaccount to see your actual earnings record and official benefit projection.
What is the break-even age for delaying benefits?
If you claim at 62 instead of 67, you receive 5 more years of payments but at a reduced amount. Generally, if you live past your mid-to-late 70s, delaying to FRA or 70 pays off more in total lifetime benefits. The SSA actuarially adjusts benefits so the "average" person breaks even, but individuals who live longer benefit more from waiting.
Can I work while receiving Social Security before FRA?
Yes, but benefits are temporarily reduced if you earn above the earnings limit ($24,480 in 2026 if under FRA). For every $2 earned above that limit, $1 of benefits is withheld. In the year you reach FRA the limit is $65,160 (2026) and $1 is withheld for every $3 above it, counting only earnings before the month you reach FRA. Once you reach FRA, there is no earnings limit. The withheld benefits are credited back to you at FRA through a higher monthly payment.
What about spousal and survivor benefits?
Spouses can claim up to 50% of a higher-earning spouse's FRA benefit as a spousal benefit (if it exceeds their own earned benefit). Survivor benefits allow widows/widowers to claim up to 100% of the deceased spouse's benefit. Divorced spouses married 10+ years are also eligible for spousal benefits.
Are Social Security benefits taxable?
Yes, up to 85% of Social Security benefits may be subject to federal income tax if your combined income (AGI + nontaxable interest + half of SS benefits) exceeds certain thresholds: $25,000 (single), $32,000 (married filing jointly), or $0 (married filing separately). Up to 50% of benefits are taxable between the first and second threshold; up to 85% above the second threshold. A handful of states also tax Social Security benefits.

Common Uses

  • •Estimate your monthly Social Security benefit at different claiming ages from 62 to 70 to optimize your retirement income strategy.
  • •Compare the lifetime benefits of claiming early versus delaying to determine which age maximizes your total Social Security payout.
  • •Understand how your full retirement age and the early claiming reduction or delayed retirement credits affect your monthly payment.

Pro Tips

  • →The 8% per year delayed retirement credit is effectively risk-free and guaranteed by the US government — it is the best "investment return" available to most retirees and exceeds current bond yields by a wide margin.
  • →Create a free "my Social Security" account at ssa.gov to get your actual earnings record and a personalized benefit estimate — this calculator's simplified AIME is no substitute for your official SSA statement.
  • →If married, the higher earner should generally delay to 70 to maximize the survivor benefit (the surviving spouse gets the higher of the two benefits). The lower earner may claim earlier.
  • →Divorced after 10+ years? You can claim spousal benefits based on your ex-spouse's record (same 50% rule) even if they remarry — as long as you remain unmarried.
  • →Check your earnings record at ssa.gov for errors — missing years of reported income reduce your AIME calculation. You have 3 years, 3 months, and 15 days to correct errors.

Limitations to Know

  • •This calculator uses a simplified AIME estimate based on current income — it assumes your current salary is representative of your career average. In reality, the SSA indexes your actual 35 highest-earning years for wage inflation, which can produce different results.
  • •The bend points used ($1,286 and $7,749) are the 2026 values, which apply to people turning 62 in 2026; they rise every year with the national average wage index, so younger workers will have higher bend points, and the estimate is in today's dollars. Estimates are capped at the SSA maximum benefit at full retirement age for 2026 ($4,152/month).
  • •The earnings test (benefit reduction if you work while claiming before FRA) is described in the FAQs but not calculated — the calculator shows what your benefit would be based solely on claiming age.
  • •Future Social Security legislative changes (benefit cuts, FRA increases, COLA formula changes) are not modeled. The 2025 Social Security Trustees Report projects the retirement (OASI) trust fund will be depleted in 2033, after which incoming payroll taxes would cover about 77% of scheduled benefits unless Congress acts.
