Social Security Claiming Age Calculator: 62 Vs. FRA Vs. 70

When Should I Claim Social Security?

Social Security Claiming Age: At a Glance

Know your FRA

Full retirement age (FRA) is 66–67 depending on your birth year. Everyone born in 1960 or later has an FRA of 67.

Claiming early costs you

Claiming at 62, the earliest possible age, locks in a permanent reduction of about 30% versus your FRA benefit.

Waiting adds up

Waiting past FRA adds 8% a year in delayed retirement credits, up to age 70. There is no reason to wait past 70.

It’s not just math

The better choice depends on your health, other income, and whether a spouse will one day rely on your benefit — not just the math.

How Your Benefit Changes by Claiming Age

Every Social Security retirement benefit starts from the same number: your Primary Insurance Amount (PIA) — what you would receive if you claimed exactly at full retirement age. Claim earlier and it is reduced. Claim later and it is increased. The formula itself is fixed by federal rule, not an estimate:

Before FRA: your benefit is reduced by 5/9 of 1% for each of the first 36 months you claim early, then by 5/12 of 1% for each additional month beyond that.
After FRA: your benefit increases by 2/3 of 1% for every month you delay, up to age 70 — equivalent to 8% for every full year.

For anyone with a full retirement age of 67 (birth year 1960 or later, now the majority of people using this calculator), that formula works out to a fixed percentage of your FRA benefit at every claiming age:

Claiming Age	% of Your FRA Benefit
62	70.0%
63	75.0%
64	80.0%
65	86.7%
66	93.3%
67 (FRA)	100%
68	108%
69	116%
70	124%

If your FRA is 66 or 66-and-some-months instead of 67 (birth years 1943–1959), the same two formulas still apply — the percentages just shift slightly since you are counting the months from a different starting point. Check your own FRA on the Social Security Administration’s full retirement age page before relying on the table above.

A Worked Example

Say your benefit at full retirement age would be $2,400 a month — somewhat above the SSA’s estimated average retired-worker benefit of $2,071 for January 2026. Here is what three different claiming ages actually put in your pocket.

Claiming Age	Monthly Benefit	Annual Benefit
62	$1,680	$20,160
67 (FRA)	$2,400	$28,800
70	$2,976	$35,712

Run those same numbers out over a full retirement and the ranking can flip. Assuming benefits are simply paid out to age 85, with no cost-of-living increases factored in to keep the math clean:

Claim at 62: roughly $463,680 received in total by 85.
Claim at 67: roughly $518,400 received in total by 85.
Claim at 70: roughly $535,680 received in total by 85 — the highest of the three.

The crossover points matter more than the endpoints. Comparing 62 to 70 directly, the breakeven age — where total dollars received catches up — lands around age 80. Comparing FRA to 70, it lands closer to age 82–83. Live past that age and delaying wins in raw dollars; die before it and claiming earlier would have paid out more. That trade-off, reduced to one sentence, is the entire actuarial bet behind this decision.

This example leaves out taxes, any investment return on benefits received earlier, and annual COLA increases, all of which shift the exact breakeven age a few years in either direction. Use it to understand the shape of the trade-off, not as a projection of your own numbers.

What Actually Decides This, Beyond the Math

The breakeven calculation gets all the attention because it is easy to compute. In practice, these five factors usually matter more:

Health and family longevity

If you have a genuine reason to expect a shorter-than-average retirement, the math tilts toward claiming earlier — even though the textbook breakeven age says otherwise. Family history and your own health picture are legitimate inputs here, not just the actuarial tables.

Other guaranteed income

If a pension, rental income, or savings can comfortably cover your expenses without Social Security, delaying to 70 functions as a guaranteed, inflation-adjusted 8%-a-year increase with zero market risk — a return that is difficult to replicate anywhere else in a retirement portfolio.

Marriage and survivor benefits

The higher earner’s claiming age sets the ceiling on what a surviving spouse can eventually receive. Delaying the higher earner’s claim — even if the lower earner claims earlier for cash flow — can meaningfully raise the eventual survivor benefit. This is one of the most consistently overlooked factors in claiming-age decisions for married couples.

Still working before full retirement age

Claim before FRA while still working, and the earnings test temporarily withholds benefits above an annual threshold. The withheld amount is not lost for good — it is repaid later as a higher benefit once you reach FRA — but it changes the short-term cash flow math.

Cash flow you need now

Sometimes the right answer is simply the age at which the household actually needs the income, independent of which age optimizes the total. A plan that is not followed because it left no room for near-term expenses is not really the optimal plan.

Common Claiming-Age Mistakes

Treating the breakeven age as the whole decision and ignoring what it means for a surviving spouse.
Claiming at 62 while still working full-time, then being caught off guard by earnings-test withholding.
Assuming benefits stop growing after full retirement age — delayed credits continue accruing up to 70.
Not checking your own FRA — for almost everyone retiring now, it is 67, not 65 or 66.
Overlooking that Social Security benefits themselves can be partially taxable depending on your other income.

Frequently Asked Questions About Claiming Social Security

What is full retirement age (FRA), and why does it matter?

FRA is the age at which you receive 100% of your Primary Insurance Amount — no reduction, no bonus. Everyone born in 1960 or later has an FRA of 67; earlier birth years have an FRA between 66 and 66-and-10-months. It is the reference point every other claiming age is measured against.

How much less will I get if I claim at 62?

About 30% less than your FRA benefit, for anyone with an FRA of 67. That reduction is permanent — it does not correct itself once you reach FRA.

How much more will I get if I wait until 70?

About 24% more than your FRA benefit, for anyone with an FRA of 67 — the result of 8% a year in delayed retirement credits for three years past FRA.

Is there any benefit to waiting past 70?

No. Delayed retirement credits stop accruing at 70. Filing later than 70 does not increase your monthly benefit any further, so there is no upside to delaying past that age.

What is the breakeven age, and should I rely on it?

It is the age at which total lifetime benefits from a later claiming age catch up to and overtake an earlier one. It is a useful way to see the shape of the trade-off, but it assumes a fixed lifespan you cannot actually know in advance — treat it as one input, not the decision itself.

Can I change my mind after I start claiming?

Within 12 months of first claiming, you can withdraw your application, repay the benefits already received, and re-file later at a higher rate. After 12 months, that option is gone, though you can still voluntarily suspend benefits between FRA and 70 to earn delayed credits on what remains.

Does my claiming age affect my spouse’s benefit?

Yes, in two ways. A spousal benefit while you are both alive is based on your PIA, not on delayed credits, so waiting past FRA does not increase what your spouse can claim on your record. A survivor benefit is different — it is based on what you were actually receiving, so delaying your own claim can directly raise what a surviving spouse receives later.

What is a spousal benefit, and when can my spouse claim on my record?

A spouse who has a smaller benefit on their own work record can claim up to 50% of your PIA instead, generally once they reach their own FRA (or reduced if claimed earlier). This is separate from their own retirement benefit and does not reduce what you receive.

If I keep working before FRA, will my benefit be reduced by the earnings test?

Temporarily, yes, if your earnings exceed the annual exempt amount. Benefits above the threshold are withheld, not forfeited — SSA recalculates your benefit upward once you reach FRA to account for the months withheld.

Does the earnings test permanently reduce my benefit?

No. It is a timing adjustment, not a penalty. The withheld amount comes back to you as a higher monthly benefit starting at full retirement age.

Are Social Security benefits taxable?

They can be. Depending on your combined income from all sources, up to 85% of your benefit may be subject to federal income tax. Your claiming age does not change this rule, but the size of your benefit — and your other income in a given year — does.

Does my claiming age affect Medicare premiums?

Not directly. Medicare Part B and Part D premiums are based on income (via IRMAA surcharges at higher income levels), not on your Social Security claiming age itself. A larger benefit can contribute to that income figure, though.

What if I’m divorced — can I claim on an ex-spouse’s record?

Potentially, if the marriage lasted at least 10 years, you are currently unmarried, and you are 62 or older. This does not reduce your ex-spouse’s own benefit or require their involvement in your claim.

Does the age I claim affect benefits for my dependent children?

It can. Certain dependent children may qualify for benefits on your record once you start collecting, generally up to a family maximum. Claiming earlier starts that eligibility window sooner, at a lower base benefit amount.

I have a shorter life expectancy than average — does that change the math?

It generally shortens the case for delaying. The breakeven calculations in this guide assume an average lifespan; a well-founded reason to expect less time in retirement is a legitimate reason to weight the decision toward claiming earlier.

Can I estimate my actual benefit amount, not just the percentages?

Yes — the calculator above this section uses your own inputs. For your official, wage-history-based PIA, create or log in to a my Social Security account at ssa.gov.

Is this calculator a substitute for professional advice?

No. It is an educational planning tool built on current federal rules to help you compare claiming ages. Your actual decision may also depend on marital status, other income, health, and other circumstances this tool does not capture — for an important claiming decision, verify your numbers with the Social Security Administration or a qualified financial professional.
