Week 25 Day 5: Social Security: Your Government-Backed Annuity

You can start Social Security at 62 (reduced benefit), 67 (full benefit for most), or 70 (maximum benefit). At 62, you get about $1,800/month. At 67: $2,550/month. At 70: $3,165/month. That extra $1,365/month (62 vs. 70) adds up to $16,380/year for the rest of your life, adjusted for inflation. If you live past 80, delaying was a massive win.

The math of delaying Social Security is compelling: each year you delay past 62 (up to 70) increases your lifetime benefit by roughly 6-8% per year. From 62 to 70, the total increase is approximately 77%. This is equivalent to buying an inflation-adjusted annuity with a guaranteed 6-8% annual return -- a return that no other risk-free investment can match. Break-even analysis: if you wait until 70 and receive $3,165/month instead of starting at 62 at $1,800/month, the higher payments offset the lost 8 years of payments at approximately age 80. If you live past 80 (the average American at 65 has a life expectancy of 84-87), delaying to 70 produces more total lifetime income. Strategy: if you can afford to live off savings from 62-70 (using your portfolio for bridge income), delay Social Security to 70. This effectively converts 8 years of portfolio withdrawals into a permanent 77% increase in your guaranteed income floor. Couples have additional strategies: the higher earner should almost always delay to 70 (maximizes the survivor benefit). The lower earner may start earlier.

The actuarial analysis of Social Security's delayed retirement credits (DRCs) is remarkably favorable compared to commercial annuities. Each year of delay past full retirement age (67 for most current workers) earns an 8% permanent increase in the benefit -- a return guaranteed by the U.S. government and indexed to CPI. Meyer and Reichenstein (2010) showed that the 'money's worth ratio' (MVR) of Social Security DRCs exceeds 1.0 for anyone with average or above-average life expectancy, meaning the present value of additional future benefits exceeds the present value of benefits forgone during the delay. For comparison, commercial inflation-adjusted annuities (from insurance companies) currently offer payout rates approximately 20-30% lower than Social Security for the same premium -- because insurance companies have profit margins and reserve requirements that Social Security does not. Shoven and Slavov (2014) demonstrated that for married couples, the optimal claiming strategy (delay the higher earner to 70, claim the lower earner's benefit earlier) can increase net present value of lifetime benefits by $50,000-100,000 compared to both claiming at 62. The SECURE 2.0 Act and ongoing Social Security reform discussions create uncertainty about future benefit levels (the trust fund is projected to deplete in approximately 2033, at which point benefits may be reduced by approximately 23%). However, even with a 23% cut, delayed benefits still exceed early benefits after age 80 in most scenarios. The political difficulty of cutting benefits for current retirees or near-retirees makes substantial near-term reductions unlikely.
