The math behind early vs delayed claiming
Every month you claim before FRA permanently reduces your benefit. Every month you delay past FRA (up to 70) permanently increases it. The SSA uses two rates: for the first 36 months before FRA, benefits are reduced by 5/9% per month (6.67%/yr). For months beyond that, the reduction is 5/12% per month (5%/yr). Past FRA, the credit is a flat 8%/yr — one of the best risk-free returns in finance.
FRA by birth year
| Birth Year | Full Retirement Age |
|---|---|
| 1954 and earlier | 66 |
| 1955 | 66 + 2 months |
| 1956 | 66 + 4 months |
| 1957 | 66 + 6 months |
| 1958 | 66 + 8 months |
| 1959 | 66 + 10 months |
| 1960 and later | 67 |
When to claim: a framework
- Claim early (62–64) if you have a serious health condition, need income to retire, or a spouse with a significantly lower benefit who will receive the spousal bump
- Claim at FRA (66–67) if you are unsure of longevity or want a clean default — no reduction, no special calculation needed
- Delay to 70 if you are in good health, have other income sources, and want to maximize the survivor benefit for a spouse
- Coordinate spouses: The lower earner claims early for household income; the higher earner delays to 70 to maximize the survivor benefit
Frequently asked questions
Should I claim Social Security at 62 or wait until 67?+
It depends on your health and break-even math. Claiming at 62 versus FRA (67 for those born 1960+) reduces your monthly benefit by about 30%. The break-even age — where total lifetime benefits equalize — typically falls around age 78–80. If you expect to live past 80, waiting usually wins on cumulative dollars. If your health is poor or you need income now, claiming early can make sense.
What is the Social Security break-even age?+
The break-even age is when the cumulative benefits from delaying surpass what you would have collected by claiming earlier. For claiming 62 vs 67, break-even is typically around age 78–79. For 67 vs 70, it is around age 82–83. Use the cumulative chart in this calculator to see exactly where the lines cross for your benefit amount.
How much does Social Security increase for each year you delay past 62?+
From FRA to 70, benefits grow at 8% per year (delayed retirement credits). Before FRA, each month of early claiming reduces benefits by 5/9% per month for the first 36 months and 5/12% per month beyond that. The total swing from claiming at 62 vs 70 is roughly 76–77% more monthly benefit for waiting — a dramatic difference if you live into your 80s.
What is Full Retirement Age (FRA) and how is it determined?+
FRA is the age at which you receive 100% of your calculated benefit — no reduction for early claiming, no credit for late claiming. It is determined by birth year: born 1954 or earlier = FRA 66; born 1955 = 66 + 2 months; born 1960+ = 67. This calculator uses SSA's exact schedule.
Are Social Security benefits taxable?+
Up to 85% of your Social Security benefit can be taxable at the federal level if your combined income (AGI + non-taxable interest + half of SS benefit) exceeds $34,000 (single) or $44,000 (married filing jointly). Eleven states also tax SS benefits. This calculator shows gross benefit amounts; run the post-tax income through a tax calculator to get net figures.
How do spousal Social Security benefits work?+
A spouse can claim up to 50% of the higher earner's FRA benefit — even if the spouse never worked. This "spousal benefit" has its own early-claiming reduction if taken before the spouse's FRA. Survivor benefits are up to 100% of the deceased spouse's benefit. Toggle "Include spousal +50%" in this calculator to model combined household benefits.
