Why Filing for Social Security at 68 May Cost You More Than You Think

Many people assume that once they reach full retirement age, waiting any longer no longer helps. But that is not quite how Social Security works. Benefits continue to grow until age 70, so filing at 68 means giving up a measurable amount of monthly income compared with waiting two more years.

That does not automatically make 68 the wrong choice. It is a middle option with its own trade-offs, and for many people it can still be a sensible decision. The numbers below use the Social Security Administration’s own rules.

Why age 68 is not a special cutoff

Social Security does not treat 68 as a major milestone the way it treats full retirement age or age 70. There is no built-in bonus or penalty at that age. It is simply a point between full retirement age, when a worker can claim 100% of their primary insurance amount, and age 70, when delayed retirement credits stop increasing benefits.

For people born in 1960 or later, full retirement age is 67, according to the SSA. Delayed retirement credits add roughly 8% a year, or about two-thirds of 1% per month, for each month benefits are delayed beyond full retirement age, up to age 70. That means someone who claims at 68 has already earned about one year’s worth of those credits, but not the full increase available by waiting until 70.

What the SSA numbers show

Take a hypothetical worker born in 1960, whose full retirement age is 67. If that worker’s primary insurance amount is $2,071 a month, that would match the SSA’s estimated average monthly benefit for retired workers starting after the latest cost-of-living adjustment.

Using the SSA’s delayed retirement credit schedule for someone with a full retirement age of 67:

At 67: $2,071 per month, or 100% of the primary insurance amount. At 68, after 12 months of delayed credits: about 108% of the primary insurance amount, or roughly $2,237 per month. At 70 or later, after 36 months of delayed credits: about 124% of the primary insurance amount, or roughly $2,568 per month.

That leaves a difference of about $331 a month between claiming at 68 and waiting until 70. Over a year, that amounts to nearly $4,000 in extra income for the person who waits.

Why the early claimant still has an advantage in hand

There is another part of the calculation that often gets overlooked. A person who claims at 68 does not just receive a smaller monthly check than someone who waits until 70. They also collect 24 additional months of payments that the later filer has not yet received.

In the example above, the 68-year-old would collect about $2,237 a month for two years, or roughly $53,688 total, before the 70-year-old receives the first payment. Once the 70-year-old begins collecting $2,568 a month, it takes time for the larger checks to make up for the earlier head start.

This is known as the break-even point, or the age when cumulative benefits from waiting catch up to and surpass the total from filing earlier. Social Security’s reduction and delayed credit formulas are designed so that, on average, lifetime benefits are similar across claiming ages.

In many cases, the break-even age for waiting from 68 to 70 falls in the early to mid-80s, though the exact point depends on the benefit amounts involved. A financial advisor or the SSA’s benefit calculators can help estimate the result for a specific earnings record.

Immediate income needs can matter more than a larger check later

For many retirement-age adults, this choice is not just about math. If someone has stopped working, used up savings, or depends on Social Security for basic expenses, waiting two more years for a larger benefit may not be practical.

The SSA’s claiming rules are meant to be actuarially neutral over an average lifetime, not to push everyone toward waiting. Filing at 68 because the money is needed now is not necessarily a mistake. It can be a rational response to current financial needs.

Health and life expectancy change the decision

Delayed retirement credits only help if someone lives long enough to benefit from the larger monthly payments. A person in excellent health with a long-lived family may have more reason to wait. Someone with serious health problems, or without a strong family history of longevity, may prefer the certainty of claiming earlier, even if that means filing at 68 rather than 70.

No one knows their lifespan in advance, so this is always a judgment call rather than a guaranteed best answer. The SSA does not factor personal health into its rules, so this decision rests with the individual and, ideally, a financial professional or trusted family members.

Survivor benefits add another consideration

One often missed factor is that delayed retirement credits can affect more than the worker’s own benefit. Under SSA rules, if a worker who earned delayed retirement credits dies, those credits can carry over and increase the surviving spouse’s benefit, since that benefit is based on the worker’s primary insurance amount plus any delayed retirement credits earned.

That means claiming at 68 instead of 70 can also reduce what a surviving spouse may receive later, especially if that spouse had lower lifetime earnings and will depend heavily on survivor benefits.

For married couples, that is a strong reason to evaluate both spouses’ records together rather than looking at one person’s filing age in isolation.

Claiming at 68 can still be the right move

None of this means 68 is a poor age to file. For someone with enough savings outside Social Security, a shorter life expectancy, or an urgent need for income, locking in a benefit that has already grown beyond the full retirement age amount can make sense.

The real lesson is not that claiming at 68 is a mistake. It is that no single claiming age works best for everyone, and the extra increase available by waiting until 70 is a real, measurable trade-off rather than an automatic win.

Bottom line

Filing for Social Security at 68 means giving up the added delayed retirement credits available by waiting until 70, but it also means receiving benefits sooner, which has value of its own. The right age depends on income needs, health, family longevity, and whether a spouse may later depend on a survivor benefit tied to the same decision.

The SSA’s online benefit estimator, available through a my Social Security account, can provide exact figures based on a person’s actual earnings record instead of averages. That is a useful place to start before deciding when to file, along with advice from a financial professional who understands the full retirement-income picture.
