Your monthly Social Security benefit comes down to a handful of key factors. The biggest is your earnings history over your working life, since benefits are designed to replace roughly 40% of pre-retirement income. But the age at which you claim is also a major variable, and understanding how it affects both the size of your check and its long-term purchasing power can make a real difference in your retirement planning.
Here is a closer look at average benefits at three key ages, and how your claiming age determines whether your income keeps up with inflation over time.
Average Social Security benefits at 62, 67, and 70
According to the Social Security Administration’s December 2025 data, the average monthly benefits break down as follows:
- $1,424.40 at age 62
- $2,016.48 at age 67
- $2,274.68 at age 70
Average benefits rise with age because the longer you wait to claim, the larger your monthly check becomes. Social Security was designed to allow claims between 62 and 70, with the system built to roughly equalize lifetime benefits for early and late claimers. To achieve that balance, Congress created a structure of early filing penalties and delayed retirement credits.
Claiming before your full retirement age triggers those penalties. They reduce your benefit on a monthly basis, adding up to a 6.7% annual reduction for each of the first three years you claim early, and a 5% annual reduction for each additional year beyond that. For workers born in 1960 or later, whose FRA is 67, claiming at 62 permanently cuts the benefit by 30%.
Waiting past your FRA works in the opposite direction. You earn delayed retirement credits equal to 2/3 of 1% per month, or 8% per year. Holding off until age 70 rather than claiming at 67 adds 24% to your monthly benefit. That increase is permanent and carries forward into every future cost-of-living adjustment.
Whose benefits are keeping pace with inflation?
Social Security benefits are not static. Cost-of-living adjustments are built into the program to protect retirees from inflation eroding the real value of their checks over time. For 2026, the SSA set the COLA at 2.8%, applied as a percentage of each beneficiary’s current benefit.
That percentage-based structure is where claiming age really starts to matter in dollar terms. Consider what the 2.8% COLA looks like at two different benefit levels. A retiree collecting the average $1,424.40 at 62 would see their benefit rise by $39.88. A retiree collecting the average $2,274.68 at 70 would receive a $63.69 boost. The percentage increase is identical, but the dollar gain is nearly $24 more per month for the later claimant. And those dollar gaps compound with every COLA that follows.
The contrast becomes even starker when you factor in fixed costs that hit all retirees equally. Medicare Part B premiums, for example, rose from $185.00 in 2025 to $202.90 in 2026, a $17.90 monthly increase that applies regardless of how large or small a recipient’s Social Security check is. Only higher earners face steeper premiums because of IRMAA. The same principle extends to everyday expenses: if the cost of groceries rises, that price increase does not soften for someone collecting a smaller benefit.
A delayed claim, by producing a higher base benefit, generates larger COLA payments in every subsequent year. Over a long retirement, that compounding effect can represent tens of thousands of dollars in cumulative additional income.
The longer-term picture: trust fund outlook
There is another dimension to the claiming-age question that has become harder to ignore. The SSA’s 2026 Trustees Report, released in June 2026, projects that the Old-Age and Survivors Insurance trust fund will be depleted in the fourth quarter of 2032. At that point, incoming payroll tax revenue would cover only about 78% of scheduled retirement benefits. The combined OASI and Disability Insurance trust funds are projected to reach depletion in 2034 if Congress does not act, at which point 83% of benefits would be payable. These projections underscore why the decision of when to claim, and what your resulting base benefit will be, carries lasting financial weight.
None of this means delaying to 70 is the right choice for every retiree. Health, financial need, spousal benefits, and other personal circumstances all factor in. Still, for those who have the flexibility to wait, a larger base benefit produces larger COLA bumps each year and provides a wider cushion against the fixed costs that tend to rise faster than any benefit check can follow. A financial advisor can help you weigh those trade-offs given your individual situation.
Editor’s note: This update adds the 2026 SSA Trustees Report projection that the OASI trust fund is expected to be depleted in the fourth quarter of 2032, with benefits payable at 78% at that time, and confirms the 2026 Medicare Part B standard monthly premium of $202.90, up $17.90 from 2025.
