Few retirement decisions are as permanent as when to start Social Security. Claim at 62, and your monthly benefit is reduced for life. Wait until 70, and it is substantially larger — but you collect nothing in the meantime. Friends, advisers and online calculators all have opinions. The right answer depends on the rules, your health, your other income and, if you are married, your spouse.
This memo explains how the numbers work.
Key Takeaways
- For people born in 1960 or later, full retirement age (FRA) is 67.
- Claiming at 62 reduces your benefit to 70% of your full amount — a 30% permanent reduction.
- Waiting past FRA earns delayed retirement credits of 8% per year, up to age 70, for a benefit of 124% of your full amount.
- The “break-even” age when delaying pays off is often around 80 to 83, but health, marriage and other income often matter more.
Benefit rules are set by the Social Security Administration (SSA). Your personal estimates are available through your my Social Security account at ssa.gov.
Full retirement age
Your full retirement age depends on your birth year. For anyone born in 1960 or later, it is 67. For people born earlier, it is between 66 and 67.
At FRA, you receive your primary insurance amount (PIA), calculated from your highest 35 years of indexed earnings.
Early claiming reductions
You can start retirement benefits as early as 62. Benefits are reduced for each month before FRA:
- 5/9 of 1% per month for the first 36 months
- 5/12 of 1% per month for additional months
For someone with an FRA of 67, claiming at 62 means 60 months early. The reduction is:
- 36 months × 5/9% = 20%
- 24 months × 5/12% = 10%
- Total: 30%
So the benefit at 62 is 70% of the PIA.
Delayed retirement credits
If you wait past FRA, your benefit increases by delayed retirement credits: 2/3 of 1% per month, or 8% per year, until age 70. There is no benefit to delaying past 70.
With an FRA of 67, waiting until 70 earns three years of credits — 24% — for a benefit of 124% of PIA.
A worked example
Suppose your PIA is $2,000 a month at 67. Ignoring cost-of-living adjustments:
- At 62: $1,400 a month
- At 67: $2,000 a month
- At 70: $2,480 a month
Comparing 62 with 70: by waiting, you give up eight years of $1,400 payments — $134,400. After 70, you receive $1,080 more each month. It takes about 124 months — just over 10 years — to make up the difference. The break-even age is around 80 to 81.
Cost-of-living adjustments apply to benefits at all claiming ages, and investment returns on money you could have saved change the picture slightly, but break-even ages for many people land roughly in the early 80s.
Factors that matter more than break-even
Health and family longevity. If you have serious health conditions or a family history of shorter lifespans, claiming earlier may make sense. If you expect to live into your late 80s or 90s, delaying can provide significantly more lifetime income.
Marriage and survivor benefits. When one spouse dies, the surviving spouse can generally keep the larger of the two benefits. If the higher earner delays, the survivor benefit is higher too. For married couples, the higher earner’s claiming age often matters more than the lower earner’s.
Other income. If you have savings or a pension to cover expenses until 70, delaying can be easier. If you need income now, claiming earlier may be necessary.
Working. If you claim before FRA while still working, the earnings test may temporarily withhold benefits.
Longevity insurance. A larger, inflation-adjusted Social Security benefit acts as insurance against outliving your savings.
Common claiming patterns
- Claim early when health is poor, income is needed, or the person is single with limited life expectancy.
- Claim at FRA as a middle ground.
- Delay to 70 when health is good, other income covers the gap, or the higher-earning spouse wants to maximise survivor benefits.
Many couples split the decision: the lower earner claims earlier, the higher earner delays.
Steps before deciding
- Check your earnings record at ssa.gov for errors.
- Get your benefit estimates at different ages.
- List income sources for the years before you claim.
- Consider your health and family history honestly.
- If married, model both spouses’ claims together.
Frequently Asked Questions
Can I change my mind after claiming? Within 12 months of claiming, you can withdraw your application once by repaying all benefits received. After FRA, you can also voluntarily suspend benefits to earn delayed credits.
Does Social Security run out of money? The trust fund is projected to face a shortfall in the coming years without changes from Congress. Even then, ongoing payroll taxes would fund most scheduled benefits. Policy changes are possible.
Should I claim early and invest the money? This can work in some cases, but it requires disciplined investing and accepting market risk.
Do I have to claim Social Security to get Medicare? No. You can enroll in Medicare at 65 without claiming Social Security.
The bottom line
The earliest claim gives you the smallest check for life; the latest gives you the largest. Use the break-even age as a reference point, but let health, marriage and your income plan drive the decision.
