Practice Management

Changes can substantially reduce the value of delaying widow(er) benefits for surviving spouses.

Under the original rules for Social Security, workers became eligible for a benefit upon reaching their full retirement age of 65, with a slight increase in benefits if the worker delayed until as late as age 70.

However, the full-retirement age itself has always been a moving target. It was pushed from 65 to 67 in 1983, and Congress frequently raises the specter of pushing it out even later—which, if acted on, could diminish the utility of a retiree delaying his/her Social Security disbursal. What follows is a look into how to navigate the knowns and unknowns of Social Security payouts.

A Moving Target

Under the original Social Security Act of 1935, workers had to reach age 65 to receive a full retirement benefit. This full retirement age, though commonly attributed to a similar “old age social insurance” program designed by Otto von Bismarck in Germany in 1889, was actually rooted in the fact that many state pension systems—and also the then-recent Railroad Retirement Benefit system—used age 65, and the Committee on Economic Security, which designed the U.S. Social Security system, decided to adopt what was already common practice.

The full retirement age remained at age 65 until 1983, when the Social Security Trust was about to run out of money, which would have caused an immediate partial cut to benefits. The subsequent National Commission on Social Security Reform, also known as the Greenspan Commission after its chairman Alan Greenspan, recommended a series of adjustments to the system to extend its stability for another 50 years.

The end result was the Social Security Amendments Act of 1983, signed into law on April 20 of that year—just a few months before the Social Security Trust Fund would have run dry—which made a wide range of changes to the system, including the increase of full retirement age from 65 to 67.

To soften the impact of the increase, the Greenspan Commission recommended a phased approach over time. Everyone who was already within 20 years of full retirement age—approximately age 45 or older at the time the law was passed—would get to keep the original full retirement age of 65. Those who were age 44 or younger—born in 1938 or later—would have to accept a higher full retirement age, but the phase-in would occur gradually over a 22-year period, with an 11-year hiatus in the middle.

The end result was that only those aged 22 or younger in early 1983—born in 1960 or later—would actually be subject to the new full retirement age of 67.

Given these birth years, every prospective retiree since 2005, upon turning age 62 and becoming eligible for early retirement benefits, has had a full retirement age of 66—as someone who turned 62 in 2005 was born in 1943. However, the 11-year hiatus of full retirement age adjustments has now come to an end, as anyone turning 62 in 2017 was born in 1955, which means their full retirement age is no longer age 66. Instead, it is—wait for it—age 66 and two months.

Difference Between Women and Men

The significance of the full retirement age is not merely that it’s the age at which retirement benefits become payable.

Since 1956, women have been able to start benefits as early as age 62—implemented at the time because wives on average were three years younger than their husbands and wanted to retire and start benefits at the same time—and the rule was expanded to allow men to retire early in 1961. However, to remain actuarially fair, Social Security stipulated that taking early retirement at age 62 would reduce benefits by 20%, which equates to 6.66% per year, or five-ninths of 1% for each month early.

With the increase in full retirement age, though, it suddenly becomes possible to retire more than three years early. Accordingly, the rules were adjusted to provide that any further early benefits beyond the first three years would be reduced at an additional 5% per year, or five-twelfths of 1% for each additional month. Consequently, in recent years when the full retirement age was 66, the total early benefits reduction was 6.66% per year for the first three years early, and another 5% for the fourth year early, for a total reduction of 25%.

Delayed Retirement Credits

Similar to the downwards adjustment for starting retirement benefits early, there’s also an increase for delaying retirement past full retirement age. Originally, these delayed retirement credits were minuscule, at just 1% per year for waiting, but 1977 Social Security amendments increased delayed retirement credits to 3% per year, and the 1983 Greenspan Commission amendments ultimately phased delayed retirement credits all the way up to 8% per year, or two-thirds of 1% per month, for delaying past full retirement age.

As a result, with a full retirement age of 66, the maximum delay to age 70 would result in delayed retirement credits of 8% per year x 4 years = a 32% increase. Notably, the 8% per year delayed retirement credits are simply cumulative, not compounded.


The significance of the increase in full retirement age from 66 to 66 and two months is that trying to take benefits at 66 is actually an early benefits election, resulting in a 1.1% reduction for starting payments two months before full retirement age.

For those who want to start as early as possible, at age 62, doing so is no longer a decision to take benefits four years early. Instead, it’s four years and two months early, which means the age-62 benefits reduction is now 25.83% instead of just 25%. Similarly, delaying to the maximum age 70 would not earn four years’ worth of delayed retirement credits (DRCs), but instead only three years and 10 months of DRCs, for a total increase of 30.67% instead of the full 32%.

The end result is that benefits can never quite be as high as they were before at the maximum, and at any given age Social Security benefits take a slight haircut.

Notably, the impact of a rising full retirement age will continue from here for several more years as well. As noted earlier, the full retirement age is scheduled to go all the way to age 67 over the next five years, such that those born in 1960 or later—i.e., those who start turning 62 in 2022—will find when making their Social Security decisions that an age-62 start date is a full 30% reduction, while delaying to age 70 is only a 24% increase.

Spousal and Survivor Benefits

In addition to changes the consequences of taking early or late retirement benefits, the change in full retirement age also affects spousal and survivor benefits as well.

In the case of spousal benefits, the standard rules stipulate that spousal benefits will be reduced by 8.33% per year—calculated as 25/36ths of 1% per month—for the first three years, and 5% per year for each additional year.

Thus, it was originally the case that taking spousal benefits at age 62 was just a 25% reduction—at 8.33% per year for three years—when the full retirement age was 65, but starting at age 62, there has been a 30% reduction for the past decade, when the full retirement age was 66, and beginning in 2017 the age-62 spousal reduction will be 30.83%, climbing to a maximum reduction of 35% in 2022 for those born in 1960 or later.

When it comes to survivor benefits, though, the rules are slightly different. Survivor benefits can be claimed as early as age 60, and the maximum reduction for starting survivor benefits that early is always a flat 28.5% reduction, applied pro-rata from the maximum retirement age back to age 60.

Thus, in the original system when the full retirement age was 65, starting at age 60 was five years early, and the reduction was 28.5%/5 years = 5.7% per year, or 0.475% per month. At full retirement age of 66, starting at age 60 is six years early, so the reduction is 28.5%/6 years = 4.75%/year, or 0.396% per month. And when full retirement age ultimately goes to 67, the reduction will be 28.5%/7 years = 4.07% per year, or 0.339% per month.

Notably, the end result of these rules is that for survivor benefits, it’s not any worse to claim benefits at the earliest age 60 as the full retirement age increases—unlike for retirement and spousal benefits. In fact, by stretching out the same reduction over a longer period, it actually lessens the monthly impact of starting early—even as it increases the number of months that must be delayed to reach the full survivor benefit.

On the other hand, it’s also important to recognize that full retirement age for survivor benefits is increasing on a different schedule than full retirement age for retirement and spousal benefits. For those who were born in 1955, whereby the full retirement age is rising to 66 and two months, the full retirement age for survivor benefits remains age 66, and only rises to 66 and two months for those born in 1957.

In turn, the full retirement age for survivor benefits isn’t only age 67 for those born in 1962 or later—as contrasted with retirement benefits, where full retirement age is 67 for everyone born in 1960 or later. As a result, for the next several years, prospective Social Security claimants will actually have to deal with two different full retirement ages: one for retirement and spousal benefits, and a slightly earlier and more favorable full retirement age for survivor benefits.

Planning Implications

Ultimately for most retirees, there’s nothing to be done about the changes in the full retirement age. They’re a function of a law that was passed over three decades ago, which simply took until now to finish their slowly phased implementation, based on the retiree’s birth year. And obviously, there’s no way to change your birth year; for better or worse, you get what you get from here.

In addition, it’s important to recognize that while the increase in full retirement age makes the adverse consequences of starting at age 62 a little more severe for retirement and spousal benefits, and the upside of waiting until age 70 less advantageous for retirement benefits, it doesn’t materially change the relative value of waiting, and the breakeven period.

For instance, an individual with a $1,000 per month retirement benefit at full retirement age of 66 could have enjoyed $750 per month at age 62, representing a 25% reduction, or $1,320 per month at age 70, a 32% increase. In the future, if that individual’s full retirement age goes to 67, it will be $700 per month at age 62, representing a 30% reduction for five years early, and $1,240 per month at age 70, a 24% increase for waiting three years.

However, in both cases, it’s still an increase of about 76% to wait from age 62 to age 70, and the breakeven period is still about the same 20-year time period. Again, the primary impact of the changing full retirement age is not actually to alter the value of waiting; it’s just to slightly reduce overall benefits.

On the other hand, when it comes to survivor benefits, the changes to full retirement age—as it begins phasing in, in another two years—lessens the reduction for starting benefits early, which actually does make it less valuable to delay. In essence, if it takes another year of waiting to undo the full 28.5% early reduction, then it takes even longer to reach the breakeven period where the higher benefits outweigh the cost of waiting.

Of course, it’s notable that when survivors have their own lesser retirement benefit, it may be advantageous to wait on survivor benefits until full retirement age, and claim individual benefits in the meantime, which can drastically reduce the breakeven period.

Nonetheless, at least on a standalone basis and when the earnings test won’t apply, later full retirement ages reduce the value of delaying survivor benefits, quite substantially.

In most situations, though, the key is simply to recognize the change that is underway, and that after more than a decade of the standard age 66, this is no longer the case, nor is it standard that starting at age 62 reduces benefits by 25%, nor that waiting until age 70 increase benefits by 32%.

Instead, for those turning 62 this year, the shift is on, with full retirement age of 66 and two months, a 25.8% haircut for starting early, and a 30.7% increase for delaying. And the transition will continue until 2022, when all retirees born 1960 or later have a full retirement age of 67, a 30% maximum reduction for starting early, and only a potential of 24% in delayed retirement credits for waiting until age 70. And in the case of survivor benefits, the transition will continue even longer, as full retirement age becomes disjointed until 2024.
