Because the math rewards it for most people. Each year you delay past Full Retirement Age earns an 8% permanent increase to your benefit: a guaranteed return very few investments match. Combined with COLA on a higher base, delaying to 70 wins on lifetime dollars if you live past about 80-81. The recommendation flips to claiming earlier only when your life expectancy is below the break-even age, or when you have health, financial, or family-history reasons to expect a shorter life.

If you die before the break-even age: typically around 80-81 for age-70 vs age-62: claiming at 62 ends up collecting more total dollars. That said, the break-even calculation ignores a critical factor: survivor benefits. If you're married and earned more than your spouse, your delayed benefit becomes their survivor benefit for the rest of their life. That insurance value often justifies delaying even when your own break-even is uncertain.

Almost never beats delaying to 70 at realistic returns. The orange dashed line on the chart simulates this scenario: invest every payment from 62 to 70, then start consuming the age-70 benefit while the portfolio keeps growing. To beat waiting to 70, you typically need sustained returns above 7-8% net of fees and taxes, which is aggressive for someone in their 60s. You also give up the longevity insurance that Social Security uniquely provides: an investment portfolio can run out; Social Security cannot.

COLA compounds in your favor when you delay. The annual cost-of-living adjustment is applied as a percentage of your current benefit, so a higher base benefit from delaying produces a bigger dollar increase every single year: for life. At a historical 2.5% average COLA, the dollar gap between age-62 and age-70 benefits widens by hundreds of dollars per year as time passes. The break-even age would be later without COLA, not earlier.

Two rules drive couple strategy. First, the spousal floor: a lower-earning spouse can claim up to 50% of the higher earner's Full Retirement Age benefit, regardless of their own work record. Second, the survivor benefit: when one spouse dies, the survivor receives 100% of the higher earner's benefit (whichever spouse's benefit is larger, the survivor keeps). The optimal split is usually for the higher earner to delay to 70 (maximizing the survivor benefit) and the lower earner to claim at or near FRA. Toggle "Include spouse" to model your specific situation.

For anyone born in 1960 or later, FRA is 67. If you were born between 1955 and 1959, your FRA is between 66 and 2 months and 66 and 10 months: close enough to 67 that the calculator's recommendations stay directionally correct, but your exact benefit amounts will differ slightly. The SSA's official benefit estimator at my.ssa.gov uses your exact birth year and earnings history.

Several real-world factors that can shift the optimal claiming age: federal and state taxation of benefits (up to 85% of SS income is federally taxable), the Social Security earnings test if you claim before FRA and keep working, Medicare Part B and IRMAA premium surcharges (which are tied to your AGI and may rise if you take large IRA withdrawals before claiming), WEP and GPO offsets for those with pensions from non-covered employment, and any future legislative changes to the program. The recommendation is a starting point, not the final answer. Run the numbers, then consult a fee-only advisor or the SSA before locking in a date.
