Most retirement advice talks about Social Security in terms of 62, 67, and 70. But if you were born between 1943 and 1954, your full retirement age (FRA) is 66, not 67. For this cohort, the people old enough to be claiming Social Security today, the comparison that actually matters is 62 vs 66.
The permanent reduction you lock in by claiming at 62, the break-even age, and the scenarios where each choice makes sense are all below. The numbers use the same SSA reduction rules as our break-even calculator, so you can check any figure here against your own benefit amount.
What full retirement age means for the 62 vs 66 decision
Full retirement age is the age at which you receive 100% of your Primary Insurance Amount (PIA), the benefit your work record is actually worth. Claim before FRA and the reduction is permanent. Claim after it and you accrue delayed retirement credits. For anyone born from 1943 through 1954, FRA is exactly 66.
| Born | Full retirement age | Most relevant comparison |
|---|---|---|
| 1943–1954 | 66 | 62 vs 66, 66 vs 70 |
| 1955 | 66 and 2 months | 62 vs 66 |
| 1956 | 66 and 4 months | 62 vs 66 |
| 1957 | 66 and 6 months | 62 vs 66 |
| 1958 | 66 and 8 months | 62 vs 66 |
| 1959 | 66 and 10 months | 62 vs 66 |
| 1960 or later | 67 | 62 vs 67 |
Because the FRA-66 group is the one eligible to claim today, most people searching "62 vs 66" fall in this cohort. The math below uses FRA 66. If your FRA is 67 (born 1960 or later), see our 62 vs 67 break-even guide.
The permanent reduction at 62 (FRA 66)
Claiming at 62 when your FRA is 66 means claiming 48 months early. SSA reduces your benefit by:
- 5/9 of 1% for each of the first 36 months early, then
- 5/12 of 1% for each additional month.
For 48 months that works out to a 25% reduction. With a $2,000/mo benefit at FRA 66, claiming at 62 pays $1,500/mo instead. That $500 difference is locked in for life; it does not grow back at FRA. (For an FRA of 67, the 62 reduction is ~30%, so the year of birth matters more than many people realize.)
The 62 vs 66 break-even age
Break-even math answers one question: how old do I have to be before waiting to 66 recoups the money I gave up by claiming at 62?
With a $2,000/mo FRA benefit, you collect $1,500/mo starting at 62 instead of $2,000/mo starting at 66. The four extra years of $1,500 checks total a $72,000 head start. The $500/mo higher benefit at 66 closes that gap at roughly age 78, the break-even age.
| Scenario (PIA $2,000 at FRA 66) | Claim at 62 | Claim at 66 | Break-even age |
|---|---|---|---|
| Monthly benefit | $1,500 | $2,000 | — |
| Head start at 66 | $72,000 | $0 | — |
| Cumulative crossover | Equal total around age 78 | 78y 0m | |
In plain terms: if you expect to live past ~78, waiting to 66 wins on cumulative dollars; if you don't, claiming at 62 pays more overall. Your own break-even age shifts with your actual benefit amounts, which is exactly what the calculator computes from your PIA and birth date.
Life expectancy is the swing factor
Break-even analysis is sensitive to one number you don't control: how long you live. The SSA 2023 period table puts life expectancy at age 62 at roughly 82 for men and 85 for women, comfortably past the ~78 break-even. That is why the actuarial math so often favors waiting when health and family history are average or better.
But averages hide real differences. If you have a serious health condition, a family history that suggests a shorter lifespan, or you simply need the income now, claiming at 62 can be the rational choice; the break-even model is a comparison, not a recommendation. Run both scenarios with your own assumptions in the calculator and treat the crossover as one input to the decision, alongside spousal and survivor implications and your other income.
When claiming at 62 makes sense
- You have a health condition or family history pointing to a shorter life expectancy.
- You need the cash flow now and have no other source of guaranteed income.
- The money replaces higher-interest debt or lets you delay drawing down tax-advantaged savings.
When waiting to 66 makes sense
- You expect average or better longevity and can cover your spending another four years.
- You're the higher earner in a couple; the larger benefit also produces a larger survivor benefit.
- You want the highest guaranteed, inflation-adjusted income you can buy with a claiming decision.

The 62 vs 66 decision is one of several claiming pairs. If waiting to 66 looks attractive, the natural next question is whether to keep going: 66 vs 70, where delayed retirement credits add about 8% per year. For the younger FRA-67 cohort, see 62 vs 67.
