Claiming Strategy for Social Security

Delaying your claim past your FRA to age 70 is mathematically equivalent to buying a single-premium immediate annuity from the federal government. The cost of this annuity is the cash flow you forego between age 67 and 70. However, unlike commercial annuities that carry insurance-company credit risk, high fees, and flat nominal payments, the Social Security version is backed by the U.S. Treasury, has zero overhead, and adjusts annually for inflation. Delaying is the cheapest, cleanest longevity insurance you can buy.

Claiming Strategy for Married Couples For married couples, the claiming strategy is even clearer:

• The higher-earning spouse delays claiming until age 70. This maximizes the monthly benefit and, critically, locks in the largest possible survivor benefit for the remaining lifetime of whichever spouse lives longer.
• The lower-earning spouse claims their own retirement benefit at FRA (or earlier if cash flow dictates).
• When the higher earner finally claims at 70, the lower earner can switch to a spousal benefit if half of the higher earner’s PIA is larger than their own benefit.
• If the higher earner dies first, the surviving spouse drops their own lower benefit and steps into the deceased’s maximized benefit.

Two variables govern the claiming decision: which spouse earned the larger benefit, and which is likely to live longer. Where those are different people — the common case, since the higher-earning spouse is frequently also the one with the shorter expectancy — the higher earner delaying to 70 is close to unconditionally right, because the delay is funded out of the shorter life and collected over the longer one. If your full FRA benefit is $1,000/month, claiming early at 64 cuts your payout to $800, and your survivor inherits $800 for the rest of their life. Delaying to 70 pushes it to $1,240 and locks that elevated figure in for whichever of you lives longer.
