• Claiming Social Security at 62 vs. 70 reduces monthly check by ~30%, costing $1,869/month or $22,433/year for life with compounding adjustments.
• Delaying Social Security to 70 is a valuable decision if you have savings, offering a permanent, inflation-adjusted higher check that protects your spouse.

Picture a 62-year-old who just retired from a job they were ready to leave. The Social Security statement says they can start collecting now, the mortgage is paid, and a check showing up next month sounds awfully nice. So they file. According to recent data, only 9% of new retirees wait until age 70 or later to claim, which means roughly 91% are leaving money on the table. The gap between claiming at 62 and claiming at 70 can run to $22,433 per year for the rest of a retiree’s life.

The instinct to grab benefits early is understandable. One retiree recently posted online asking whether there was “any meaningful reason” for his wife to delay past 62, since the money was right there and the future felt uncertain. Thousands of people ask that question every year, and the answer almost always comes down to one number.

Why the Claiming Age Decision Dwarfs Everything Else

Social Security gives you a permanent raise for every year you wait between 62 and 70. Claiming at 62 cuts your monthly check by roughly 30% from what you would get at full retirement age. Wait past full retirement age, and the check grows by about 8% per year up to age 70. After 70, the increases stop.

Here is the math in plain dollars. The average new retiree claiming at 62 receives about $1,292 per month. The average new retiree claiming at 70 receives about $3,162 per month. That is a difference of roughly $1,869 every month, or $22,433 a year, for life. Over a 20-year retirement, the cumulative gap runs into the hundreds of thousands of dollars.

The larger check also compounds. Social Security applies every annual cost-of-living adjustment to your starting benefit, so a bigger base means bigger raises forever. With the Consumer Price Index sitting at 335.123 in May 2026 versus 308.417 in January 2024, COLA increases have been meaningful, and they hit the age-70 starting figure much harder in dollar terms than the age-62 figure.

How This Fits With the Rest of Your Retirement

Delaying Social Security only works if you have a way to pay the bills in the meantime. That usually means drawing down savings, working part-time, or both. The trade is straightforward: spend some of your IRA in your 60s in exchange for a much larger guaranteed, inflation-adjusted check from the federal government starting at 70.

That trade looks even better when you consider how stretched household budgets already are. The average household spent $78,535 in 2024, and the personal savings rate has fallen to about 4% in early 2026, down from 6% two years earlier. A bigger Social Security check is one of the few sources of guaranteed lifetime income that keeps up with inflation, which makes it the right asset to maximize and the wrong asset to shrink for the sake of convenience.

For married couples, the stakes get higher. When the higher-earning spouse delays, the survivor benefit also grows, protecting the spouse who lives longer.

What to Think Through Before You File

Two things worth sitting with before claiming:

1. The decision is essentially permanent. Once you claim, your monthly benefit locks in for life, adjusting only for inflation. There is no rewind button at 75 when you realize the check is too small.
2. Delaying is a longevity hedge. Most people who claim early run out of other savings in their 80s. Social Security designed the age-70 check to land exactly when you need it most.

Health, marital status, and other income sources all change the calculation, so the right age for your neighbor may not be the right age for you. Run your own numbers through the Social Security Administration’s calculators, and if the situation is complicated, pay an hour of a fee-only planner’s time before you file. A bad claiming decision costs you decades, not months.
