When to Claim Social Security: Age 62, 67, or 70

The single largest financial decision most Americans make in retirement is when to claim Social Security. The right answer for the median worker is almost never age 62 — but more than half of all retirees still claim early. The arithmetic of waiting is more compelling than most people realize.

The three reference ages

• Age 62 — early retirement age. The earliest age you can claim. Permanent reduction of roughly 25%–30% from your Primary Insurance Amount (PIA), depending on your full retirement age.
• Full retirement age (FRA) — 66 to 67. The age at which you receive 100% of your PIA. For anyone born 1960 or later, FRA is 67.
• Age 70 — maximum claim age. Every year of delay past FRA adds 8% via delayed retirement credits, capped at age 70. For an FRA of 67, claiming at 70 produces 124% of PIA.

The percentage adjustments, precisely (FRA = 67)

The breakeven analysis

The simple cumulative-dollars breakeven between claiming at 62 vs. claiming at 70 is around age 80–82 (depending on COLA and discount-rate assumptions). For a single individual who expects to die before 80, claiming early produces more total dollars. For one who expects to live past 80, claiming late produces more — and the upside grows substantially for every year of life past 85.

Life expectancy at age 65 in the U.S. is about 84 for males and 86 for females (CDC, 2023 period life tables). For couples, the relevant statistic is joint life expectancy — at least one of two 65-year-olds is expected to live to about 92. The breakeven framing suggests waiting wins for the median household.

The survivor benefit, the underweighted factor

When the higher-earning spouse dies, the surviving spouse "steps up" to the deceased spouse's benefit (under §202(e) of the Social Security Act). Claiming early permanently reduces the survivor benefit your spouse will collect for the rest of their life. For a couple where one spouse expects to outlive the other by a decade, the higher earner's claim age should be optimized for the survivor, not the claimant.

Worked example: two-earner couple

Husband age 67 (FRA), PIA $3,000/month; wife age 65 (FRA 67), PIA $1,500/month. Husband expects to die around 82; wife expects to live to 92.

• Both claim at 62: husband $2,100, wife $1,050. After husband's death at 82, wife steps up to $2,100 for 10 more years.
• Husband delays to 70, wife claims at 62: husband $3,720 from age 70 to 82, wife $1,050 from 62 to 92. After husband's death, wife steps up to $3,720 for 10 more years.

The husband's 8-year delay adds about $250,000 of survivor-benefit value over the wife's 10-year widowhood, at a cost of roughly $200,000 in his own foregone benefits between 62 and 70. Net: the late claim wins by about $50,000 for this couple, before COLA — and far more if the wife lives past 92.

The earnings test (a separate article in this library)

Claim early and still work? Benefits collected before FRA are reduced by $1 for every $2 of earnings above $23,400 (2025). In the year you reach FRA, the reduction is $1 for every $3 above $62,160. Above FRA, no reduction. See our Earnings Test article for the full mechanic.

Common mistakes

• Claiming at 62 to "get the money before it runs out." Social Security is a contractually defined benefit. Even in the most pessimistic CBO trust-fund projection, the post-2033 benefit is roughly 79% of full — meaningful, not "gone."
• Treating spouses' claims independently. Optimization is joint, not separate. The higher earner's claim drives the survivor benefit.
• Forgetting about Medicare timing. Medicare enrollment is independent of Social Security claiming — sign up at 65 regardless of when you claim Social Security, or face permanent late-enrollment penalties.
• Skipping the Restricted Application opportunity (where eligible). Born before January 2, 1954? A few claim strategies preserved under the grandfather provisions of the 2015 Bipartisan Budget Act still apply. Most are now closed.
