Social Security Claiming Age Calculator: 62, 67 or 70, after tax

Your situation

Quick start

These give you a full answer. The rest uses typical assumptions; open the sections below to fine-tune.

Your benefit at full retirement age /mo, from your statement

The "full retirement age" amount on your my Social Security statement at ssa.gov (your PIA), in today's dollars.

Your birth year and month

Age you plan to claim 62 to 70; 66.5 = 66 and 6 months

yrs

Age you plan to live to blank = life-table average

yrs

I'm married

Spouse's benefit at full retirement age /mo, 0 if none

Spouse's birth year

Age your spouse plans to live to blank = average

yrs

Other taxable income in retirement /yr

Pensions, traditional IRA and 401(k) withdrawals, interest. It decides how much of your benefit is taxed. Roth withdrawals don't count.

Return on savings, after inflation /yr

What your savings earn while you wait to claim. A dollar of benefit at 62 could earn this until 70, so a higher return favors claiming earlier.

Your spouse's claim

Age your spouse plans to claim 62 to 70

yrs

Spouse's birth month

Life expectancy

Used only when an age to live to is left blank. The averages come from Social Security's period life table, which doesn't allow for future gains in longevity, so they run a little short.

Life table for you

Life table for your spouse

Taxes

Filing status

Married couples are taxed as filing jointly; a survivor files as single from the year after the death.

Tax-exempt interest /yr, municipal bonds

Not taxed itself, but it counts toward the income that decides how much of your benefit is taxed.

State tax on Social Security 0 in most states

Applied to the federally taxable part. Most states don't tax benefits; a few do, often with their own exemptions.

Inflation /yr

The income levels at which benefits become taxable are fixed in dollars and never rise with inflation, so each year more of your benefit is taxed.

Still working

Your pay while working /yr, 0 if retired

Working until age

yrs

Benefit growth and the trust fund

Benefit growth above inflation /yr, 0 = keeps pace

Trust-fund scenario: benefit cut used in one scenario only

…starting in

The 2026 Trustees Report projects the combined trust funds run out in 2034, after which taxes would cover about 83% of scheduled benefits (the retirement fund alone: late 2032, 78%). Congress has always acted before; this is a scenario, not a prediction.

Running total of benefits after tax, by your age

Year-by-year benefits, tax and running total for your planned claiming ages
Year	Your age	You	Spouse	Taxable part	Tax on benefits	After tax	Running total

Every claiming age, side by side

Monthly benefit, lifetime value at three life spans and break-even for each claiming age
Claim at	Your check	Live to 80	Your plan	Live to 95	Break-even

What could change the answer

Highest-value claiming age and lifetime value under each scenario
Scenario	Highest-value age	Lifetime value there	At your plan	Claiming at 62

Lifetime value: benefits after tax, in today's dollars, valued at your age 62 using your savings return. It compares ages; it isn't a forecast of what you'll receive.
