The Unfortunate Truth About Claiming Social Security at Your Full Retirement Age

Your decision about when to claim Social Security is one of the most consequential financial choices you will make in retirement. You have an eight-year window to start benefits, but claiming at 62 (the earliest option) produces a very different outcome than claiming at 70 (the age at which delayed credits stop accruing). The gap between those two choices can amount to hundreds of dollars a month for the rest of your life, and it compounds further with each annual cost-of-living adjustment.

For many people, full retirement age feels like the natural default. Full retirement age, or FRA, is the point at which you become eligible for your standard benefit, also called your primary insurance amount. Claiming at FRA requires no complicated math, no sacrifice of early checks, and no waiting beyond what already feels like a long career. So why not simply file then?

A closer look at the numbers reveals that claiming at FRA is often the least-optimized choice available. Here is why.

When is your full retirement age for Social Security?

Your FRA depends entirely on when you were born. Here is the schedule based on your birth year:

For anyone born in 1960 or later, FRA is 67. That is two full years later than the age-65 threshold that applied to earlier generations, and it is the permanent FRA under current Social Security law. The 1983 Social Security Amendments set this phase-in in motion, raising FRA in two-month increments by birth year until it reached 67 for the 1960 birth cohort. By 2026, that 42-year phase-in is fully complete. Reaching FRA, however, does not mean you are receiving the largest benefit available to you.

Why claiming Social Security at full retirement age may not be the right move

The case against claiming at full retirement age rests on one straightforward fact: benefits keep growing after FRA. Each month you delay past your FRA, your monthly check rises by 2/3 of 1%, and that accumulation continues until you turn 70, at which point no further delay earns additional credits.

That monthly rate translates to an 8% annual increase. Consider a retiree whose FRA benefit is $2,000 per month. Waiting three full years to claim at 70 produces a 24% boost, lifting that payment to $2,480 and delivering $5,760 more per year. That higher base persists for life. The concrete stakes appear in the SSA’s published 2026 maximums: a worker with a full earnings history could receive $4,152 per month at FRA, $5,181 at 70, and only $2,969 at 62. Choosing FRA over 70 in that scenario means forgoing roughly $1,000 per month, every month, for the rest of one’s life.

Inflation protection adds yet another layer to the advantage of delaying. Social Security cost-of-living adjustments are applied as a percentage of your full benefit amount, so a larger base produces larger dollar gains each year. The 2026 COLA came in at 2.8%, lifting the average retired worker’s monthly payment by $56, from $2,015 to $2,071. The 2027 COLA, announced by the SSA on October 14, 2026, will be 3.6%, the largest adjustment since 2023, pushing the average monthly benefit to roughly $2,170 starting in January. Because each year’s percentage is applied to the full benefit, the dollar gap between someone who delayed and someone who claimed early widens a little more with every annual adjustment.

Should you wait to claim your Social Security?

The core question is whether a delay will maximize the total benefits you collect over your lifetime. An extra $480 per month only pays off if you live long enough to recoup the checks you skipped. A working paper from the National Bureau of Economic Research found that more than 90% of Americans between the ages of 45 and 62 would optimize lifetime income by waiting until 70 to claim.

The reason delaying benefits so many people traces back to the original design of the delayed retirement credit system. Actuaries calibrated it when life expectancies were shorter, intending to equalize total lifetime payouts regardless of when a person claimed. Rising lifespans have tilted the math firmly in favor of those who wait, because they now collect the higher benefit for more years than the original designers anticipated.

The program’s long-term finances add yet another dimension to this decision. According to the Social Security Board of Trustees’ 2026 annual report, released June 9, 2026, the OASI retirement trust fund is projected to be depleted in the fourth quarter of 2032, at which point ongoing payroll tax revenue would cover only 78% of scheduled retirement benefits. The combined retirement and disability fund (OASDI) faces depletion in the third quarter of 2034, when 83% of benefits would remain payable. The Trustees also reported that the program’s 75-year actuarial deficit grew to 4.42% of taxable payroll, up from 3.82% in the prior year’s report, a 16% deterioration driven in part by tax provisions in the 2025 legislation commonly known as the “One Big Beautiful Bill.” Congress has addressed past shortfalls and could act again, but the deteriorating trajectory adds real weight to the timing decision for anyone still years from claiming.

To figure out the right timing for your own situation, calculate your break-even age: the point at which the higher monthly benefit from delaying overtakes the cumulative checks you gave up while waiting.

The math works like this:

• Calculate how much income you gave up by waiting: If your FRA benefit is $2,000 and you wait until 70, you forgo three years of $2,000 monthly checks, totaling $72,000.
• Calculate how much higher your delayed benefit is: A $2,000 FRA benefit grows to $2,480 at 70, generating $480 more per month.
• Find the break-even point: Divide $72,000 by $480 per month and you get 150 months, or 12.5 years beyond your claiming age of 70.

Someone who claims at 70 breaks even at roughly age 82 to 83. Given that many retirees reach that milestone, waiting beyond FRA tends to be the stronger financial move. Health, personal finances, and other individual circumstances still matter in every case, and a financial advisor can help you build a personalized analysis around your specific situation.

Editor’s note: The inflation section was updated to include the SSA’s 2027 COLA of 3.6%, announced October 14, 2026, which will raise the average monthly benefit to roughly $2,170 in January 2027, the largest adjustment since 2023.
