Social Security Break-Even Age: 62 vs. 67 vs. 70

The classic question everyone asks before claiming Social Security: at what age does waiting start to pay off? It is a legitimate question, and the arithmetic is not complicated. What makes this decision harder than the math is everything the break-even calculation ignores — health, taxes, a spouse, and sequence risk. Both things are true: you need the numbers, and the numbers alone will mislead you.

Here are the numbers first. Then the four things they miss.

What you gain and lose at each age

For anyone born in 1960 or later, full retirement age (FRA) is 67. That is the baseline the SSA uses to define your "full" benefit. Everything else is measured against it.

Claiming at 62 triggers a permanent 30% reduction. The math: the SSA cuts your benefit by 5/9 of 1% per month for the first 36 months before FRA and by 5/12 of 1% per month for the next 24 months. With FRA at 67, that's 60 months total, producing exactly a 30% cut. On a $2,000/month FRA benefit, you get $1,400/month instead — forever, for as long as you live.

Claiming at 70 earns delayed retirement credits of 8% per year (or 2/3 of 1% per month) for every month you wait past FRA. Three years of credits adds 24%, so the same $2,000 FRA benefit becomes $2,480/month at 70. Credits stop accruing at 70; waiting past that adds nothing.

In 2026 dollars, the SSA's published maximum benefits show this spread in concrete terms:

Claiming age	2026 maximum monthly benefit
62	$2,969
67 (FRA)	$4,207
70	~$5,108

Those are the extremes for workers with 35+ years at the taxable wage maximum ($184,500 in 2026). The average retired worker collects $2,071/month under the 2026 COLA adjustment. Your personal number sits somewhere in between — the SSA's "my Social Security" portal gives your actual estimated benefit at each claiming age.

The three break-even calculations

All three calculations below use nominal dollars with no investment return assumed on benefits received (the zero-discount-rate version). Applying a discount rate of 3–5% pushes each break-even age roughly 2–4 years later.

62 vs. 67: If your FRA benefit is $1,000/month, claiming at 62 gives you $700/month; waiting gives you $1,000. Your five-year head start at 62 accumulates $42,000 (60 months × $700) before the 67 claimer starts. After 67, the $300/month advantage compounds: $42,000 ÷ $300 = 140 months = about 11 years and 8 months past age 67. Break-even: approximately age 78 years, 8 months.

67 vs. 70: Waiting from 67 to 70 trades three years of $1,000/month checks ($36,000 foregone) for an extra $240/month permanently. Recouping: $36,000 ÷ $240 = 150 months = 12 years, 6 months past age 70. Break-even: approximately age 82 years, 6 months.

62 vs. 70: The widest gap — $700/month vs. $1,240/month — requires recovering eight years of $700 payments ($67,200) at the $540/month advantage. $67,200 ÷ $540 ≈ 124 months ≈ 10 years, 4 months past age 70. Break-even: approximately age 80 years, 4 months.

A quick reference:

Comparison	Break-even age (no discount rate)
62 vs. 67	~78 years, 8 months
67 vs. 70	~82 years, 6 months
62 vs. 70	~80 years, 4 months

The Social Security actuaries have done their jobs: the three claiming ages are roughly actuarially equivalent for someone with average life expectancy. If you knew exactly when you would die, this would be a simple optimization. You don't.

Four factors the break-even calculation doesn't touch

1. Your health and family history. The break-even math assumes average mortality. If you have serious health problems or a family history of early death, the 62 column looks better than the table suggests. If your parents and grandparents lived into their late 80s and you are healthy at 62, the math strongly favors waiting. The break-even age for the 62-vs-70 comparison (80 years, 4 months) is below average life expectancy for a healthy 62-year-old today — which means the average healthy person comes out ahead by waiting.

2. Spousal and survivor benefits. This is where the single-person break-even framing fails married couples most completely. A spouse with little or no work history can claim up to 50% of your FRA benefit on your record. If you claim early at a reduced rate, that spousal floor also drops. More importantly, when one spouse dies, the survivor keeps the higher of the two benefits — which means the higher earner's delay is survivor insurance, not just a personal longevity bet. Couples maximizing the survivor benefit almost always want the higher earner to delay to 70.

3. Taxes on benefits. Between $25,000 and $34,000 of "combined income" (AGI + nontaxable interest + half your SS benefits) for single filers, up to 50% of your benefit becomes taxable. Above $34,000, up to 85% is taxable. For married couples, those thresholds are $32,000 and $44,000. If you are still working and claim at 62, there is a real chance you are paying income tax on benefits you don't need — effectively reducing the cash value of early claiming. The pre-FRA earned-income penalty compounds this: in 2026, the SSA withholds $1 of benefits for every $2 you earn above $24,480 if you claim before FRA.

4. How benefits interact with your portfolio. If your alternative to claiming early is drawing from a portfolio in down markets, comparing nominal checks understates the value of delaying. A hypothetical retired couple with $600,000 in savings who faces a 30% market decline in years 1–3 will draw that portfolio down dramatically faster if they are not yet collecting Social Security. Conversely, if your portfolio is large and your spending is lower than the sustainable withdrawal rate, collecting early may let you leave more assets growing — and the break-even math understates the value of early claiming.

Who should claim at each age

There is no universal answer, but the patterns are clear:

Claim at 62 if: you have a serious health condition that shortens life expectancy, you are the lower-earning spouse with no survivor-benefit implications, you cannot afford to wait without drawing down assets at an unsustainable rate, or you have earned-income that stays below $24,480 (otherwise the benefit gets clawed back and you might as well wait).

Claim at 67 (FRA) if: you expect average health and longevity, you are working part-time in your mid-60s and want to avoid the earned-income penalty, or the survivor-benefit analysis for your specific spouse situation points here rather than to 70.

Claim at 70 if: you are the higher-earning spouse in a married couple, you are in good health with a family history of longevity, your portfolio can cover 2–3 more years of spending without undue stress, or you are doing significant Roth conversions in your late 60s and want to minimize taxable income before required minimum distributions hit at 75. The 8% guaranteed annual credit from 67 to 70 is arguably the best guaranteed return available to most retirees — higher than most bond yields with no credit risk.

Running your own numbers

The worked example above uses a $1,000/month FRA benefit for simplicity. Your actual number from the SSA changes the break-even ages modestly (higher benefits move break-even slightly earlier; the percentages are fixed). What matters more than the precise month is the directional decision — and that decision improves considerably once you factor in a spouse, your actual health picture, and what your portfolio looks like in your early 60s.

The Social Security break-even calculator runs the comparison with your specific FRA benefit, your discount rate assumption, and optional spouse inputs. Once you have the SS timing pinned, the retirement income planner models how that claiming decision interacts with your portfolio drawdown and tax exposure across the full retirement timeline.

Granary keeps all of those variables — Social Security timing, portfolio withdrawals, Roth conversions, ACA premiums, and RMDs — in one model rather than optimizing them in isolation, which is where the real decisions are made.
