Your full retirement age determines your standard benefit amount — claiming before or after it permanently changes how much you receive every month.
Full retirement age (FRA) is the age at which you're entitled to your full, unreduced Social Security benefit — the Primary Insurance Amount calculated from your earnings history. It's not the same for everyone; it depends on your birth year, and it's not the same as the earliest age you can claim (62) or the latest age it makes sense to wait (70).
| Birth Year | Full Retirement Age |
|---|---|
| 1943-1954 | 66 |
| 1955 | 66 and 2 months |
| 1956 | 66 and 4 months |
| 1957 | 66 and 6 months |
| 1958 | 66 and 8 months |
| 1959 | 66 and 10 months |
| 1960 and later | 67 |
You can start claiming as early as 62, but your benefit is permanently reduced — not just temporarily lowered. The earlier you claim relative to your FRA, the larger the reduction, and this reduced amount (with cost-of-living adjustments) is what you'll receive for the rest of your life, even after you technically reach your FRA.
For someone with an FRA of 67, claiming at exactly 62 — a full 5 years early — results in a reduction of roughly 30% off the full benefit amount, permanently. Claiming just one year early, at 66, results in a much smaller reduction, since the reduction scales with how many months early the claim happens relative to FRA, not as a flat penalty for claiming "early" in general.
For each year you delay claiming past your FRA, up to age 70, your benefit increases through delayed retirement credits — commonly around 8% per year of delay. There's no additional benefit to delaying past 70 — waiting beyond that age doesn't increase your monthly amount any further.
Claim early (62-FRA): Smaller monthly checks, but more total checks over time — can make sense if you need the income sooner or have health/longevity concerns.
Delay (FRA-70): Larger monthly checks for life, but fewer total checks if you don't live long enough to "break even" — can make sense if you expect a long retirement or have other income to bridge the gap.
The break-even age is the point at which the total cumulative amount received from delaying claiming catches up to, and then surpasses, the total that would have been received by claiming earlier. Someone who claims at 62 receives smaller checks starting sooner, and for a number of years, their cumulative total actually stays ahead of someone who waited until 67 or 70 — since the early claimant has simply been collecting longer. Eventually, the larger monthly amount from delayed claiming catches up and overtakes it, typically somewhere in the late 70s to early 80s depending on the specific ages compared. Living past that break-even age means delaying paid off in total dollars received; not living that long means claiming early would have provided more lifetime income. Since nobody knows their own lifespan in advance, this is fundamentally a decision made under uncertainty, not one with a single objectively correct answer.
Family longevity history, current health, and whether other income sources (savings, a pension, continued part-time work) can cover expenses in the years before claiming all factor into this decision alongside the pure break-even math. Someone with a strong family history of longevity and other income to bridge the gap may lean toward delaying, capturing the larger permanent benefit. Someone who needs the income immediately, or has health concerns that make a shorter retirement more likely, may reasonably prioritize claiming earlier despite the permanent reduction — since a larger monthly check that arrives too late to matter provides no actual benefit.
Key Takeaway: Full retirement age is the reference point every claiming decision is measured against — claiming earlier permanently reduces your benefit, and delaying (up to 70) permanently increases it through delayed retirement credits. The break-even age shows when delaying starts paying off in total lifetime dollars, but health, family longevity, and other income sources matter just as much as the raw math in deciding what's right for a given situation.
For anyone born in 1960 or later, full retirement age is 67 — this applies regardless of how much later than 1960 you were born.
It can be, particularly if you need the income immediately, have health concerns affecting life expectancy, or aren't working and have no other income source to bridge the years until FRA.
No — delayed retirement credits stop at age 70, so there's no financial benefit to waiting any longer than that to claim.
It's the age at which delaying benefits results in more total lifetime income than claiming earlier — useful as a reference point, though it can't account for how long any individual will actually live.
Yes — since the break-even math depends heavily on how long benefits are collected, personal and family longevity history is one of the most relevant factors alongside the raw numbers.
