Social Security Timing
Claim at 62, 67, or 70? It's the biggest financial decision most retirees face — and the answer depends entirely on how long you live.
The core tradeoff
Social Security lets you start benefits any time between ages 62 and 70. Your Full Retirement Age (FRA) is 67 if you were born in 1960 or later — that's the baseline. Claim earlier and you get smaller checks for more years. Claim later and you get bigger checks for fewer years. The total money is roughly the same — if you live to the average life expectancy.

How the reduction is calculated
The reduction isn't arbitrary — the IRS designed it to be actuarially equivalent for the average person. For every month you claim before FRA, your benefit is permanently reduced. For every month you delay past FRA (up to 70), it's permanently increased.

Understanding the break-even age
The break-even age is when cumulative lifetime benefits from the later start finally overtake the earlier start. Before the break-even, early claiming has paid out more total money. After it, the higher monthly check from waiting has caught up and taken the lead.
| Comparison | Break-even age | Interpretation |
|---|---|---|
| 62 vs 67 | ~78–79 | Live past ~79 → claiming at 67 wins |
| 67 vs 70 | ~82–83 | Live past ~83 → claiming at 70 wins |
| 62 vs 70 | ~80–81 | Live past ~81 → claiming at 70 wins |
The average US life expectancy at 65 is about 84 for men and 86 for women — past the 67→70 break-even for many people. But personal health, family history, and financial need all matter more than averages.
It's not just about longevity
Break-even analysis assumes a simple world. Real Social Security decisions involve more moving parts:
Spousal & survivor benefits
If you have a spouse, your benefit becomes the survivor benefit when you die. Delaying the higher earner's claim to 70 often maximizes the survivor's lifetime income.
Investment opportunity cost
If you delay to 70, you might draw down other savings earlier. If those savings would have earned more than the 8%/year delayed credit, claiming earlier could be better.
Tax on Social Security
Up to 85% of your benefit is taxable if your income is high enough. Delaying while doing Roth conversions can lower your overall tax burden significantly.
Medicare coordination
Medicare Part B premiums are deducted from SS benefits. If you delay SS to 70 but take Medicare at 65, you'll need to pay Part B premiums directly until SS starts.
RMD interaction
At 73, required minimum distributions from traditional accounts can push you into higher brackets. SS income on top of RMDs can significantly increase your tax bill.
Still working at 62–66?
If you claim SS before FRA while working, the earnings test can temporarily reduce your benefit ($1 withheld per $2 earned above ~$22k). After FRA, no limit.
Quick decision guide
If: Health is poor or family history suggests shorter life
→ Claim early (62–64)
If: Average health, need income now, no other savings
→ Claim at FRA (67)
If: Good health, have other income, married (survivor benefit matters)
→ Delay to 70
If: High earner married to lower earner
→ Higher earner delays to 70; lower earner claims earlier
If: Still working before FRA
→ Wait — earnings test will reduce benefit anyway
