Claim Social Security at 62, 67, or 70?
Here's the Actual Math

When to claim Social Security is arguably the most consequential financial decision most Americans will ever make. Get it wrong and you could leave $100,000–$200,000 on the table over a lifetime. Get it right and you could boost your guaranteed monthly income by 30–76% compared to the earliest option. Here's the complete breakdown.

First: understand what Social Security actually pays

Your Social Security benefit is based on your 35 highest-earning years (adjusted for inflation). The Social Security Administration calculates your Average Indexed Monthly Earnings (AIME) and then applies a formula called the Primary Insurance Amount (PIA) — the benefit you'd receive if you claimed exactly at your Full Retirement Age (FRA).

The 2025 PIA bend points are:

The maximum Social Security benefit at FRA in 2025 is $4,018/month ($48,216/year). The average is closer to $1,800–$2,200/month.

What is Full Retirement Age (FRA)?

FRA is the age at which you receive 100% of your PIA benefit. For anyone born in 1960 or later, FRA is 67. For those born in 1943–1954, it's 66. Between those cohorts, it scales up by 2 months per birth year.

Birth YearFull Retirement Age
1943–195466
195566 + 2 months
195666 + 4 months
195766 + 6 months
195866 + 8 months
195966 + 10 months
1960 or later67

The three claiming ages — compared

Claim at 62 — Earliest possible

You get money sooner, but your benefit is permanently reduced. If your FRA is 67, claiming at 62 cuts your benefit by 30% — forever. On a $2,200/month FRA benefit, that's $1,540/month instead. The reduction is 5/9 of 1% per month for the first 36 months early, and 5/12 of 1% per month beyond that.

Claim at FRA (67 for most people) — Your baseline

You receive 100% of your calculated benefit. No reduction, no bonus — just your full entitlement. For most people born 1960+, this is age 67.

Claim at 70 — Maximum benefit

For every year you delay beyond FRA (up to age 70), your benefit increases by 8% per year — guaranteed, risk-free. Waiting from 67 to 70 (3 years) boosts your monthly check by 24%. On a $2,200/month FRA benefit, that's $2,728/month. This is the highest return on any "investment" most Americans can access.

The concrete numbers — a real example

Let's say your FRA benefit (PIA) is $2,500/month. Here's what each claiming age delivers:

Claim AgeMonthly BenefitAnnual BenefitChange vs FRA
62$1,750/mo$21,000/yr−30%
63$1,875/mo$22,500/yr−25%
64$2,000/mo$24,000/yr−20%
65$2,083/mo$25,000/yr−16.7%
66$2,167/mo$26,000/yr−13.3%
67 (FRA)$2,500/mo$30,000/yrBaseline
68$2,700/mo$32,400/yr+8%
69$2,900/mo$34,800/yr+16%
70$3,100/mo$37,200/yr+24%

The difference between claiming at 62 vs 70 is $1,350/month — for life. On a 20-year retirement, that's $324,000 in additional lifetime income (not counting COLA adjustments).

The break-even age: when does waiting pay off?

Here's the core tradeoff: claim early and get payments for more years, but each payment is smaller. Wait and get fewer but larger payments. At some age, the cumulative total crosses over — that's your break-even age.

For claiming at 70 vs 67 (with a $2,500 FRA benefit):

If you expect to live past 82–83, waiting to 70 wins in total lifetime dollars. The average American man lives to 76; the average woman to 81. But these are averages — if you make it to 65, your life expectancy is already 84 (men) and 87 (women).

Key insight: Break-even ages are typically 12–15 years after the later claiming age. Most healthy Americans who reach 65 will live past that break-even. Waiting usually wins — but your health, cash needs, and other income sources matter enormously.

Factors that favor claiming EARLY (62–64)

Factors that favor waiting (67–70)

The married-couple strategy: The #1 Social Security optimization for married couples is for the higher earner to delay to 70 while the lower earner claims at 62 or FRA. Why? The higher earner's benefit becomes the survivor benefit — the amount the surviving spouse receives for the rest of their life. Maximizing it protects the surviving spouse from poverty in old age.

The COLA factor — often forgotten

Social Security benefits are adjusted annually for inflation via the Cost-of-Living Adjustment (COLA). In 2025, the COLA was 2.5%. This COLA applies to your current benefit amount — so a higher starting benefit means bigger dollar increases every year. Over 20 years at 2.5% COLA, the gap between early and late claiming widens further in favor of waiting.

What about the "earnings test" before FRA?

If you claim SS before your FRA and continue working, the SSA temporarily reduces your benefit: in 2025, they withhold $1 of benefit for every $2 you earn above $22,320/year. (The year you reach FRA, the threshold increases and only $1 is withheld per $3 earned above $59,520.)

Important: The withheld amounts are recredited to your benefit at FRA — it's not permanently lost. But the earnings test is a strong argument for waiting to claim if you're still working.

Spousal and survivor benefits

A spouse (including divorced spouse married 10+ years) can claim up to 50% of the higher earner's FRA benefit, regardless of their own work history. This makes the higher earner's claiming decision even more critical.

When one spouse dies, the survivor can claim the deceased spouse's full benefit (if it's higher than their own). This "survivor benefit" is permanently boosted if the higher earner delayed to 70 — it's one of the strongest reasons for the higher earner to wait.

The bottom line: what should YOU do?

There is no universal right answer. But here's a useful framework:

  1. If you're in poor health: Claim early. The math favors it when life expectancy is shortened.
  2. If you're healthy, single, and have savings: Strong case for waiting to 70. The guaranteed 8%/year return is hard to beat.
  3. If you're married and the higher earner: Very strong case for delaying to 70 to maximize the survivor benefit.
  4. If you need income now: Claim when you need it. A smaller check now beats no check.
