The short answer
For someone born in 1970 earning $75,000/year over 25 working years, the estimated full-retirement-age (67) benefit is $2,109.49/month. Claiming at 62 drops that to $1,476.64/month; waiting until 70 raises it to $2,615.77/month. The break-even age between claiming at 62 versus 70 is about 80.4 — live past that, and delaying pays more in lifetime total.
Key takeaways
- Every month you claim before full retirement age (FRA) permanently reduces your benefit; every month you delay past FRA (up to 70) permanently increases it.
- The reduction and increase rates are not symmetric: early reduction is roughly 6.67%/year for the first 3 years before FRA, then 5%/year beyond that, while delayed credits are a flat 8%/year up to age 70.
- The break-even age (about 80.4 in this example) is the point where cumulative benefits from delaying to 70 catch up to and pass cumulative benefits from claiming at 62.
- This calculator's benefit estimate is simplified — it uses your current earnings and years worked rather than your full 35-year indexed earnings history, so treat it as a planning estimate, not an official figure.
Benefit by claiming age, in full
| Claiming Age | Monthly Benefit |
|---|---|
| 62 (earliest) | $1,476.64 |
| 65 | $1,828.23 |
| 67 (full retirement age) | $2,109.49 |
| 70 (maximum) | $2,615.77 |
The spread between the earliest and latest claiming age is substantial — $2,615.77 at 70 is 77% more than the $1,476.64 available at 62, on identical underlying earnings. That difference compounds every single month for the rest of your life, which is why claiming age is often called the single biggest lever most people have over their own retirement income.
The break-even age, and why it's not the whole story
8 years of head-start checks at $1,476.64/month ≈ $141,757 collected by age 70
Monthly gap (70 vs 62) = $2,615.77 − $1,476.64 = $1,139.13
Break-even ≈ age 80.4
Claiming at 62 gives an 8-year head start of checks the age-70 claimant never gets, but those checks are smaller. The higher monthly amount from delaying eventually makes up the difference — in this example, around age 80.4. Assuming a life expectancy of 85, lifetime totals favor delaying further still: $407,553.79 collected from claiming at 62, versus $455,650.20 at FRA (67) and $470,838.45 at 70. Life expectancy, health, other income sources, and whether you need the money sooner all matter more than the break-even age alone — it's a useful reference point, not the whole decision.
