Retiring at 62 and living off a 401(k) until 70 keeps a couple in the 12% tax bracket, with an effective federal rate near 8% on roughly $133,000 in annual withdrawals. Delaying Social Security to 70 grows each spouse's benefit by 8% per year, producing roughly $6,200 combined monthly in guaranteed, inflation-adjusted income plus a maximized survivor benefit.
