Claiming age is a break-even problem, not a slogan. Compare the checks and the cumulative dollars.

The short answer

Claiming age is a bet on how long you'll live.

Social Security pays the same lifetime present value at every claiming age if you live an average lifespan — the system is roughly actuarially fair. The decision is really about risk: claiming at 62 gives you smaller checks for more years; waiting to 70 gives you the largest possible check, fully inflation-protected, for as long as you live. With the default $2,400 full retirement age (FRA) benefit, this tool shows about $1,680/mo at 62, $2,400/mo at FRA, and $2,976/mo at 70, with the cumulative-dollar break-even near age 80.

How it works

Early reduction, then delayed credits.

Your primary insurance amount (PIA) is the benefit you get at FRA — for anyone born in 1960 or later, FRA is 67. Claim early and the benefit is reduced for life; claim late and you earn delayed retirement credits worth 8% per year up to age 70.

The model applies your annual COLA to keep both the early and delayed streams in roughly comparable dollars, then compares cumulative checks through your life-expectancy input to find the break-even age.

The math

The formula behind each number.

B62 = PIA × 0.70  |  BFRA = PIA  |  B70 = PIA × 1.24
Break-even ≈ 70 + (B62 × 12 × 8) / (B70 × 12 − B62 × 12)
  • PIA — estimated monthly benefit at full retirement age
  • B62 — reduced benefit if claimed at 62
  • B70 — increased benefit if claimed at 70
  • 8 — the 8-year head start (ages 62–70) that early claiming banks before the delayed claimer starts
A worked example

$2,400 at FRA, born 1964, 2.4% COLA, life expectancy 86.

Walk it by hand
1. Benefit at 62: $2,400 × 0.70 = $1,680/mo
2. Benefit at FRA: $2,400/mo (100% of PIA)
3. Benefit at 70: $2,400 × 1.24 = $2,976/mo
4. Extra monthly dollars from waiting: $2,976 − $1,680 = $1,296/mo
5. Dollars banked by the early claimer over the 8-year head start: $1,680 × 12 × 8 = $161,280
6. Break-even ≈ 70 + 161,280 / (35,712 − 20,160) = 70 + 10.4
Break-even ≈ age 80 — past 80, the age-70 strategy collects more total dollars

Live to your input of 86 and waiting to 70 wins comfortably. Expect a shorter lifespan, need the income sooner, or want to retire fully at 62, and claiming early can still be the rational choice.

Methodology & sources

Where these numbers come from.

Methodology
  • Early/delayed factors approximate SSA reduction and delayed-credit rules for an FRA of 67 (SSA Retirement Benefits).
  • Delayed retirement credits of 8% per year to age 70 per SSA.gov benefit rules.
  • COLA, earnings test, taxation, and spousal/survivor rules summarized from official SSA publications; verify your exact PIA on your my Social Security statement.

Glossary

Social Security terms, decoded.

PIA (Primary Insurance Amount)
The benefit you receive at full retirement age, computed from your highest 35 years of inflation-indexed earnings.
FRA (Full Retirement Age)
The age you get 100% of your PIA — 66 for those born 1943–1954, rising to 67 for anyone born 1960 or later.
Delayed retirement credit
An 8% per year increase for delaying benefits between FRA and 70. Nothing accrues after 70.
Earnings test
A temporary withholding ($1 per $2 over the limit) if you claim before FRA and keep working; recalculated upward at FRA.
COLA
The annual cost-of-living adjustment tied to the CPI-W that keeps benefits roughly inflation-protected.
Break-even age
The age at which the larger delayed checks have made up for the years of checks skipped by waiting.
Spousal benefit
Up to 50% of the higher earner's PIA, payable to a spouse; does not earn delayed credits.
Survivor benefit
Up to 100% of what the deceased worker was actually receiving, including any delayed credits earned.

FAQ

Social Security questions, answered.

Claiming at 62 cuts a benefit born in 1960 or later by about 30% for life; waiting past FRA adds 8% per year up to age 70, roughly a 24% boost over an FRA of 67. If you expect to live past the break-even age (usually around 80), waiting wins on cumulative dollars. If you have a short life expectancy, need the cash, or want to stop working early, claiming early can be the right call.

You earn delayed retirement credits of 2/3 of 1% per month, or 8% per year, for every year you delay between FRA and 70. There is no credit for waiting past 70, so 70 is the last age worth delaying. A $2,400 FRA benefit grows to about $2,976 at 70 in this model.

It is the age at which the larger delayed checks have paid back the years of checks you skipped by waiting. With a $2,400 FRA benefit, the early-vs-delayed break-even lands around age 80. Live past it and waiting paid off; die before it and claiming early collected more total dollars.

If you claim before FRA and keep working, SSA temporarily withholds $1 of benefits for every $2 earned above an annual limit ($23,400 in 2025), or $1 for every $3 in the year you reach FRA. The withheld amount is not lost: SSA recalculates and raises your benefit once you hit FRA. After FRA there is no earnings test at all.

A spouse can receive up to 50% of the higher earner's PIA at the spouse's full retirement age, reduced if claimed earlier. Spousal benefits do not grow with delayed retirement credits, so the higher earner delaying past FRA does not increase the spousal portion.

A surviving spouse can receive up to 100% of what the deceased worker was actually receiving, including any delayed retirement credits the worker earned. This is why the higher earner delaying to 70 is often valuable: it permanently raises the survivor benefit for whichever spouse lives longer.

Possibly. Based on combined income (adjusted gross income + nontaxable interest + half of benefits), up to 50% of benefits become taxable above $25,000 single / $32,000 joint, and up to 85% above $34,000 single / $44,000 joint. These thresholds are not indexed for inflation, so more retirees owe tax over time.

COLA is the annual inflation increase SSA applies to benefits, tied to the CPI-W. It has averaged roughly 2 to 3% over recent decades but varies year to year (8.7% for 2023, 2.5% for 2025). The calculator uses your COLA input to keep purchasing power roughly steady across both claiming ages.

Yes. The early-claiming reduction is permanent except for the later COLA adjustments and any earnings-test recalculation at FRA. A benefit claimed at 62 stays at roughly 70% of the FRA amount for life, which also lowers the survivor benefit a spouse may later receive.

FRA is the age you receive 100% of your primary insurance amount. It is 66 for people born 1943-1954, rises in two-month steps for 1955-1959, and is 67 for anyone born 1960 or later. Claiming before FRA reduces the benefit; claiming after earns delayed credits to age 70.
