The decision of whether to delay Social Security benefits is a trade-off: give up benefits now, in exchange for higher payments in the future. If the higher payments are received for enough years – dubbed the “breakeven period” – the retiree can more than recover the foregone benefits early on, even after adjusting for inflation and the time value of money.
With couples, however, the decision to delay is more complex. Earning 8%/year delayed retirement credits can not only boost an individual’s own retirement benefit, but increases the potential survivor benefit as well… which means the breakeven can be reached as long as either member of the couple remains alive long enough! In turn, this makes delaying benefits even more appealing, as the odds of at least one member of a couple remaining alive is better than the single life expectancy of either member in particular.
