Social Security claim age comparison

About this calculator

Social Security claiming — when to start, how much it costs to wait

The key tradeoff: claim early at a permanently reduced benefit, or wait for a larger monthly check that takes longer to accumulate. The math turns on expected longevity.

The benefit schedule

For people whose Full Retirement Age (FRA) is 67:

62: 70% of FRA benefit (30% reduction, permanent)
65: ~87% of FRA
67 (FRA): 100%
68: 108%
69: 116%
70: 124% (8% delayed retirement credit per year past FRA)

Each year you wait between FRA and 70 adds 8% to your monthly benefit for life. After 70, no further increase.

The crossover years

Claim at 62 vs 67: lifetime benefits equal around age 78-79
Claim at 67 vs 70: lifetime benefits equal around age 82-83

So if you live past 79, claiming at 67 beats 62. If past 83, claiming at 70 beats 67.

Average US life expectancy at age 65: ~84 (men), ~87 (women). The math leans toward delayed claiming for most people, especially women and those with longevity in the family.

When to claim early anyway

Health issues suggesting shorter expected lifespan
No other income + can't physically work to 67/70
Spousal optimization: lower-earning spouse claims early, higher-earning spouse delays to 70 to maximize survivor benefit
Big tax-deferred balances to draw down: claiming SS later lets you spend down 401(k)/IRA in lower brackets

When delayed claiming wins big

Family longevity (parents lived past 85)
Married, primary earner: your benefit becomes the survivor benefit — delaying maximizes your spouse's lifetime income
Continuing to work: you'd have earnings test reductions if you claim at 62 while still working; delaying avoids this

FAQ

What's COLA and why does it matter?

Cost-of-Living Adjustment — annual SSA increase tied to CPI-W. Recent COLAs: 8.7% (2023), 3.2% (2024), 2.5% (2025). It applies once you're claiming, so larger benefit + COLA compounds — another argument for delaying. Historical average is ~2.5%.

Does working past 65 increase my benefit?

Possibly. SSA recalculates your benefit each year you have earnings, using your top 35 earning years. If a higher-earning year replaces a low or zero year, your benefit goes up. Most workers see modest bumps; those who had spotty earlier work history can see meaningful increases.

What about the spousal benefit?

A spouse can claim 50% of the higher earner's FRA benefit (reduced if claimed before their own FRA). Survivor benefit equals 100% of deceased spouse's benefit. Delayed retirement credits transfer to survivor benefit — another reason for the higher earner to delay to 70.

Should I worry about Social Security running out?

The Trust Fund is projected to deplete around 2034 under current law. Even if Congress does nothing, payroll taxes still cover ~77% of scheduled benefits indefinitely. Realistically, Congress will adjust (some mix of higher payroll cap, modest benefit slowdown, slight retirement-age increase). Plan for some haircut, but not a wipeout.
