Claiming-Age Comparison Worksheet — 62 vs 67 vs 70
Side-by-side comparison of monthly benefits, lifetime benefits, and break-even ages for the three most common Social Security claiming choices, with a worked example using a $2,000 PIA.

The Social Security claiming-age decision is the largest single-decision financial swing most retirees will ever make. The range from earliest claim (age 62) to latest claim (age 70) is roughly 77% of monthly benefit for someone with Full Retirement Age of 67 — before any cost-of-living adjustments, before tax interactions, before survivor coordination.
This worksheet compares the three most common claiming ages — 62, FRA, and 70 — with a worked example you can adapt to your own Primary Insurance Amount (PIA).
The setup — find your PIA
Your Primary Insurance Amount is the monthly benefit you'd receive if you claimed exactly at Full Retirement Age. For anyone born in 1960 or later, FRA is 67.
Pull your PIA from your "my Social Security" statement at ssa.gov/myaccount. Look for the line labeled "Your retirement benefit at full retirement age."
For this worksheet we'll use a PIA of $2,000/month as the running example. Substitute your own number and the math scales linearly.
The three numbers — 62, 67, 70
For someone with FRA of 67 (born 1960 or later):
| Claim age | Monthly benefit | vs. PIA | Annual benefit |
|---|---|---|---|
| 62 (earliest) | $1,400 | −30% (permanent reduction) | $16,800 |
| 67 (FRA) | $2,000 | 0% (PIA) | $24,000 |
| 70 (latest) | $2,480 | +24% (Delayed Retirement Credits) | $29,760 |
The range between 62 and 70 is $1,080/month ($12,960/year), or about 77% of the monthly benefit at 62.
This is per individual. For a married couple where both spouses claim, the spread doubles in absolute dollars.
How early-claim reduction works (62 to FRA)
Claiming before FRA reduces your benefit using a specific formula:
- 5/9 of 1% per month for each of the first 36 months before FRA
- 5/12 of 1% per month for each additional month beyond 36
For someone with FRA of 67 claiming at 62 (60 months early):
- First 36 months × 5/9% = 20% reduction
- Next 24 months × 5/12% = 10% reduction
- Total: 30% permanent reduction
A $2,000 PIA becomes $1,400 at 62, for life. The reduction does not "catch up" — there's no point at which the early-claim person starts getting a higher benefit than they would have at FRA.
| Claim age | Months before FRA | Reduction |
|---|---|---|
| 62 | 60 | 30% |
| 63 | 48 | 25% |
| 64 | 36 | 20% |
| 65 | 24 | ~13.3% |
| 66 | 12 | ~6.7% |
| 67 (FRA) | 0 | 0% |
How Delayed Retirement Credits work (FRA to 70)
Delaying past FRA adds Delayed Retirement Credits at 2/3 of 1% per month, which equals 8% per year.
For someone with FRA of 67 delaying to 70:
- 36 months × 2/3% = 24% permanent increase
A $2,000 PIA becomes $2,480 at 70, for life.
| Claim age | Months past FRA | Increase |
|---|---|---|
| 67 (FRA) | 0 | 0% |
| 68 | 12 | 8% |
| 69 | 24 | 16% |
| 70 | 36 | 24% |
After age 70, no further increase applies. This is the cap — there's no benefit to delaying past 70.
Lifetime benefit comparison — break-even math
The naive "break-even" framing asks: at what age does the cumulative benefit from claiming later exceed the cumulative benefit from claiming earlier? Run the cumulative arithmetic, ignoring inflation, taxes, and investment returns:
| Age | Cumulative if claimed at 62 | Cumulative if claimed at 67 | Cumulative if claimed at 70 |
|---|---|---|---|
| 62 | $16,800 | $0 | $0 |
| 65 | $67,200 | $0 | $0 |
| 67 | $100,800 | $24,000 | $0 |
| 70 | $151,200 | $96,000 | $29,760 |
| 75 | $235,200 | $216,000 | $178,560 |
| 80 | $319,200 | $336,000 | $327,360 |
| 82 | $352,800 | $384,000 | $386,880 |
| 85 | $403,200 | $456,000 | $476,160 |
| 90 | $487,200 | $576,000 | $624,960 |
Break-even ages:
- 62 vs. 67 break-even: about age 78–79
- 67 vs. 70 break-even: about age 82–83
- 62 vs. 70 break-even: about age 80–81
If you live to 80, claiming at 67 outperforms claiming at 62. If you live to 83, claiming at 70 outperforms claiming at 67.
Important caveats: these break-even ages ignore COLA (which slightly shifts the math toward later claiming), ignore taxes (later claiming may result in higher Social Security taxability if other income stays constant), ignore investment returns on the early-claimed dollars (which shifts back toward earlier claiming), and ignore survivor benefits (which are the single biggest reason higher earners delay).
Why break-even isn't the whole story
The break-even framing is useful as a starting point, but several interactions can flip the decision:
1. Survivor benefits. When the higher earner of a married couple dies, the surviving spouse's benefit becomes the larger of their own benefit or the deceased spouse's benefit. So the higher earner's claiming age locks in the surviving spouse's lifetime income.
If the higher earner has a $2,500 PIA and claims at 62 (gets $1,750), the survivor floor is $1,750. If they delay to 70 (gets $3,100), the survivor floor is $3,100. That's $1,350/month in additional survivor income, for the rest of the lower-earning spouse's life.
For most married couples with significant earnings disparity, this single factor pushes the higher earner toward delaying — often well past the naive break-even age.
2. Tax interactions. The taxable portion of your Social Security benefit depends on a "combined income" formula. Up to 85% of benefits can be taxable depending on other income. Higher Social Security benefits combined with significant other taxable income can push more of the benefit into the taxable portion.
This makes "delay to 70" slightly less valuable on an after-tax basis than on a pre-tax basis. The effect is typically small but worth modeling for high-income retirees.
3. Withdrawal sequencing. If you delay Social Security, you're likely withdrawing more from pretax accounts in the gap years. That's actually useful from a Roth-conversion-window perspective — but it accelerates the depletion of your pretax balance.
A coordinated plan models claiming age jointly with withdrawal sequencing and Roth conversion sizing, not as three independent decisions.
4. Longevity uncertainty. The break-even math assumes a known lifespan. For someone with strong family longevity history (parents lived into their 90s) or strong personal health, the case for delaying is stronger than for someone with health uncertainty.
The honest framing: delay-to-70 is longevity insurance. You're paying for it (via foregone early benefits) and the payoff is higher benefits when you need them most — the late-life period when other portfolio assets may be depleted.
When claiming at 62 makes sense
Claiming at 62 isn't always wrong. It can be the right call when:
- Cash-flow need is acute. You don't have the bridge income to delay, and pulling more from portfolio assets in the gap years would damage the plan more than the lower benefit hurts.
- Longevity expectation is short. You have known health conditions that meaningfully shorten your expected lifespan; the higher cumulative benefit at 62 wins.
- You're a much-lower-earning spouse. The higher earner's claiming age drives the survivor benefit; the lower earner's claiming age has less joint-life impact, so claiming early to access cash isn't a strategic loss.
- You have a strong pension or other guaranteed income. Social Security is a smaller piece of your retirement income, so the longevity insurance case is weaker.
- You plan to invest the early benefits. If you genuinely have a low near-term need for the income and a strong investment thesis, the invested-benefit math can compete with delayed claiming. (This is rare in practice; most early-claim "I'll invest it" plans don't materialize.)
The honest decision checklist
For the higher earner of a married couple:
- Confirm your PIA from ssa.gov/myaccount.
- Calculate your 62, 67, and 70 monthly benefits using the formulas above (or the table — they're linear in your PIA).
- Project your spouse's longevity. The higher earner's claiming age protects the surviving spouse for life.
- If you're considering claiming before FRA: confirm you have a documented need, not just a preference for "money in hand."
- If you're considering delaying past FRA: confirm you have a bridge-income source for the gap years (pretax withdrawals are fine; having to sell taxable assets at a loss is not).
- Coordinate with your withdrawal-sequencing and Roth-conversion plan for the gap years — they should be modeled jointly.
For the lower earner of a married couple:
- Different math applies. Your claiming age has less leverage over joint-life income (the higher earner's claiming age dominates the survivor benefit). Optimize for cash-flow simplicity in the gap years.
For a single retiree with no spouse:
- Survivor coordination doesn't apply, but longevity insurance does. Delay-to-70 is more attractive the longer your expected lifespan.
