Social Security: The Most Important Retirement Decision
For most Americans, Social Security will be their largest guaranteed lifetime income source in retirement. The average retired worker receives approximately $22,000 per year in Social Security benefits — and for one-third of retirees, Social Security provides 90% or more of their income. The decision of when to claim benefits — which you can make at any point from age 62 to 70 — is one of the most consequential financial decisions you'll ever make. A suboptimal claiming strategy can cost tens or hundreds of thousands of dollars in lifetime benefits.
Age 62: Earliest claiming age. Benefit permanently reduced by 25–30% from FRA benefit. Age 67 (for those born 1960+): Full Retirement Age — 100% of your earned benefit. Age 70: Maximum benefit age. Benefits increase 8% per year from FRA to 70, yielding a benefit 24–32% higher than FRA amount. After age 70, there is no additional increase.
How Social Security Benefits Are Calculated
The Social Security benefit formula is progressive — it replaces a higher percentage of income for lower earners. Someone earning the minimum wage receives approximately 57% income replacement; someone at the maximum taxable earnings ($168,600 in 2024) receives approximately 28% replacement. This is why Social Security is especially critical for middle and lower-income retirees.
- 1Claim at 62: Benefit = $2,000 × 70% = $1,400/month (30% reduction)
- 2Claim at 67 (FRA): Benefit = $2,000/month
- 3Claim at 70: Benefit = $2,000 × 124% = $2,480/month (24% increase)
- 4Total lifetime benefits to age 85 (at 62): $1,400 × 12 × 23 years ≈ $386,400
- 5Total lifetime benefits to age 85 (at 67): $2,000 × 12 × 18 years ≈ $432,000
- 6Total lifetime benefits to age 85 (at 70): $2,480 × 12 × 15 years ≈ $446,400
- 7Break-even: Claiming at 70 vs. 62 breaks even around age 80
Benefit Reduction and Increase Rates
| Claiming Age | FRA = 67 (Born 1960+) | FRA = 66 (Born 1943–1954) |
|---|---|---|
| 62 | 70% of FRA (−30%) | 75% of FRA (−25%) |
| 63 | 75% of FRA (−25%) | 80% of FRA (−20%) |
| 64 | 80% of FRA (−20%) | 86.67% of FRA (−13.33%) |
| 65 | 86.67% of FRA (−13.33%) | 93.33% of FRA (−6.67%) |
| 66 | 93.33% of FRA (−6.67%) | 100% of FRA |
| 67 | 100% of FRA | 108% of FRA (+8%) |
| 68 | 108% of FRA (+8%) | 116% of FRA (+16%) |
| 69 | 116% of FRA (+16%) | 124% of FRA (+24%) |
| 70 | 124% of FRA (+24%) | 132% of FRA (+32%) |
Spousal and Survivor Benefits
Social Security provides important benefits for married couples, divorced spouses, and surviving spouses that significantly affect the optimal claiming strategy. Spousal benefit: a lower-earning spouse can claim up to 50% of the higher earner's FRA benefit. Survivor benefit: a surviving spouse receives up to 100% of the deceased spouse's benefit (including any delayed retirement credits). This makes it particularly valuable for the higher earner to delay claiming to age 70 — not just for their own benefit, but to maximize the survivor benefit that will continue for a potentially much longer period.
Social Security Claiming Strategies
Factors to Consider When Claiming
If you claim Social Security before your Full Retirement Age and continue working, the Retirement Earnings Test applies. In 2026, SSA temporarily withholds $1 of benefits for every $2 earned above $22,320/year (before FRA). These withheld benefits are credited back to you at FRA, slightly increasing your monthly benefit. If you plan to work significantly before FRA, waiting to claim may be more advantageous.
