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 eithermember 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.

However, if you’re a lower-earning spouse anticipating a future survivor benefit, it’s actually lessvaluable to delay at all. After all, if the lower-earning spouse’s benefit will eventually be “overwritten” by a survivor benefit anyway, there’s not much benefit to trying to increase it for just a limited number of years!

Which means ultimately, the ideal strategy for most couples is for the higher-earning spouse to delay as long as possible (which benefits them as long as either remains alive) and start the lower-earning spouse’s benefits as early as possible to gain the additional years of benefits. If both spouses delayed benefits, they would both need to live into their 90’s in order to recoup the lost years of benefits the lower earner would have captured starting early.

The Breakeven Period For Delaying Social Security Retirement Benefits

For those who don’t yet want or need their Social Security retirement benefits at full retirement age, the Social Security system allows individuals to delay their benefits and earn an 8%/year “delayed retirement credit” instead. This is often described as an “8% guaranteed return” for delaying Social Security benefits, although in reality the benefit of delaying is not quite that significant – for the simple reason that while benefits may increase by 8% for every year the retiree waits, that also means the retiree doesn’t receive any money for that year!

Accordingly, the proper way to evaluate the benefit of delaying Social Security benefits is to view it as a trade-off, where the retiree gives up known dollars today, in exchange for receiving higher payments for life beginning at some point in the future. For instance, choosing to wait on retirement benefits from full retirement age (currently age 66 for those born between 1943 and 1954) until the maximum age 70 results in a 4 years x 8%/year = 32% increase in benefits, in exchange for the fact that no benefits will be received for those 4 years.

Example 1. Larry is eligible for a $2,000/month Social Security benefit at his full retirement age, but chooses to delay his benefits by 4 years, boosting his benefits by 32% to $2,640/month (plus cost-of-living adjustments). However, the decision to wait 4 years and get an “extra” $640/month will have a “cost” to Larry, in the form of $2,000/month (plus cost-of-living adjustments) he will not receive for the next 4 years.

This trade-off can be evaluated on the basis of a “breakeven period” – for how many years must Larry receive an extra $640/month to recover the four years of (lower) benefits he didn’t receive while waiting.

For instance, assuming 3% inflation and a 6% growth rate,  Larry must live 21 years, until age 87, to begin to come out ahead by delaying. Though notably, if Larry lives beyond the breakeven period, the compounding now begins to work in his favor, and Larry can end up significantly further ahead in the long run, especially if inflation is higher than expected or portfolio returns are worse than anticipated.

How A Widow’s Eligibility For A Survivor Benefit Changes The Breakeven For Delaying

In the case of a married couple, the likely impact of delaying Social Security benefits can be even more favorable. The reason is that with a married couple, when one person passes away, the survivor is eligible for a widow(er) benefit equal to 100% of the deceased spouse’s retirement payments. That means the decision to begin retirement benefits early or delay them late impacts not only the size of the retiree’s own benefit, but the size of the survivor benefit that will be payable to a spouse as well.

Thus, the benefit of delaying retirement benefits as the member of a married couple is that the higher benefit will be payable for the life of the retiree, and the lifetime of the survivor if the retiree passes away first. In other words, as long as either member of the couple lives long enough to see the breakeven period, it pays to have delayed – either in the form of a higher (delayed) retirement benefit, or a higher survivor benefit based on that delayed retirement benefit! Which means the odds of reaching the breakeven period for a couple increase significantly, as it’s no longer based on the life expectancy of the retiree, but instead on the joint life expectancy of the couple.

Of course, the caveat to delaying in order to earn a higher survivor benefit is that ultimately a survivor only receives the greater of the survivor benefit or his/her own retirement benefit. As a result, if both members had substantial income in the working years and will have similar retirement benefits, the higher survivor benefit is of little or no value.

Example 2. Larry is eligible for a $2,000/month benefit at full retirement age, and his wife Lisa is eligible for an even higher benefit – in fact, Lisa is eligible for the maximum individual benefit in 2015 of $2,685/month based on her work history. As a result, if Larry passes away, Lisa will not get any survivor benefit, because her own benefit is already higher than the potential survivor benefit! Even if Larry delays until age 70 – pushing his benefits $640/month higher thanks to the 32% increase from delayed retirement credits – the delay will only boost his benefit (to $2,640/month) but still will not generate any additional survivor benefit for Lisa if he passes away first, because Lisa is already eligible for more than this survivor benefit herself!

The end result – given that Lisa’s own retirement benefits will already be higher, delaying Larry’s benefits will increase only his benefits and not Lisa’s survivor benefits, and the potential for higher survivor benefits should no longer be a factor in Larry’s decision to delay. Instead, the decision of whether or not to delay benefits should be based solely on Larry’s own life expectancy and the likelihood that he will reach his breakeven point on his own.

The Problem With A Lower-Earning Spouse Delaying Retirement Benefits

As the earlier example showed, the benefit of Larry delaying Social Security benefits is limited to his own benefit, as Lisa cannot receive a survivor benefit when her own benefits are already higher. However, the fact that Lisa’s benefits are higher creates an additional complication to the scenario – it actually further reduces the benefit for Larry to delay at all!

The reason is that not only will Larry not be able to leave a survivor benefit for Lisa (because her benefits are already higher), but if Lisa dies first, her survivor benefit payment to Larry will overwrite his own benefit! Which means Larry’s effort to delay his benefits may be a moot point!

Example 3. Larry decides to delay his retirement benefits until age 70 to earn 32% in delayed retirement credits. However, just before his 70th birthday, his wife Lisa passes away, and as a result Larry will begin to receive a $2,685/month survivor benefit from Lisa. And notably, Larry was going to receive a $2,685/month survivor benefit from Lisa regardless of whether he started at full retirement age or delayed until age 70. As a result, his decision to delay four years simply means he gave up four years of benefits that he will never recover, not because he passed away before reaching the breakeven period, but because his wife passed away first.

As the above example illustrates, the caveat to delaying Social Security benefits as the lower-earning spouse is that ultimately the delay only works as long as both members of the couple remain alive – Larry must remain alive long enough to reach the breakeven period, and Lisa must remain alive long enough to allow Larry to reach the breakeven period without overwriting his benefit with her own survivor amount.

Early Claiming Strategies For Spouses Anticipating A Higher-Earner’s Survivor Benefit

Notably, while there is a risk for Larry to delay benefits – given that either his death or Lisa’s death will cause him to fail to reach the breakeven point – there may actually be a benefit for Lisa to delay benefits instead.

After all, in this scenario, Lisa is the higher earning spouse, and her decision to delay benefits until age 70 will boost her benefits by 32% (in this case, from $2,685/month to $3,544/month) and will boost the amount of the survivor benefit that Larry is eligible for. After all, while Lisa won’t benefit from Larry delaying to boost his survivor benefit, Larry does benefit by having Lisa delay to boost her survivor benefit instead! If Lisa delays and then passes away first, Larry’s benefit will be stepped up from his $2,000/month up to Lisa’s $3,544/month instead, enjoying not only a higher benefit but the full additional payments that Lisa gets by delaying.

In fact, given that Lisa’s higher survivor benefit is looming, not only is there benefit for the couple to delay Lisa’s benefits – which will be valuable as long as either of them are alive (in the form of either Lisa’s retirement benefit or her survivor benefit for Larry) – but there is even less value to delay Larry’s benefits at all. Which means Larry would probably not want to delay benefits from full retirement age until 70, and if he had the opportunity, he would probably want to start benefits as early as possible at age 62!

More generally, the key distinction to recognize is that when couples have substantively different benefits and are considering the breakeven periods, delaying the higher earner’s benefit will win as long as either person is alive at the breakeven, but delaying the lower earner’s benefit will only win if both of them are alive at the breakeven point. Notably, for those couples where at least one spouse plans to wait until age 70, but wants to get some benefits in the meantime, special rulescalled “File-and-Suspend” and “Restricted Application” make this possible, but are being phased out in the coming years. If you will turn full retirement age of 66 by the end of April 2016 you should contact your financial planning professional to explore whether it makes sense to engage in this strategy before the deadline has passed.

In summary, the point remains that with a married couple, the decision to delay benefits must be evaluated based on the life expectancy and health of both members of the couple. If both are in poor health, it still won’t pay to delay at all. And if both are in great health – and both can live well beyond the breakeven period – there can still be a value for both to delay. But for those of ‘merely average’ life expectancy, the most common strategy will be to delay the higher earning spouse as long as possible (a strategy that wins as long as either of them are alive into their 80s) but to start the lower earning spouse’s benefits as early as possible (a strategy that only wins in the less likely scenario that both of them remain alive through their 80s and beyond!).
