Short Answer
Claim Social Security early if you expect a shorter life or need the income now; delay to 70 if you expect a long life or want the largest possible guaranteed check. The deciding number is the break-even age: the age at which the larger delayed checks catch up to the smaller early ones. Live past it and waiting pays more; fall short and claiming early pays more. For someone born in 1960 (full retirement age 67) with a $2,000 benefit at FRA, claiming at 62 pays $1,400 a month while waiting to 70 pays $2,480 a month. The break-even age is about 80.4, so living to 90 makes delaying worth about $124,800 more over a lifetime.
Key Takeaways
- One number decides it: the break-even age. Live past it → delaying wins; fall short → claiming early wins.
- Claiming at 62 cuts the benefit up to 30%; waiting to 70 raises it 24% (when FRA is 67) - an age-70 check about 77% larger than an age-62 check.
- The early reduction is 5/9 of 1% per month for the first 36 months and 5/12 of 1% beyond; the delayed credit is 8% per year to age 70.
- Living longer favors delaying; a short life expectancy favors claiming early.
- Delaying is longevity insurance, most valuable for the higher earner in a couple because the larger benefit can continue as a survivor benefit.
- A discount rate pushes the break-even later; COLAs apply to every option and roughly cancel out of the comparison.
- This is a pre-tax timing test; taxes on benefits, the earnings test, and spousal benefits still matter.
How the Comparison Works
The tool puts each claiming age on the same footing - total benefits collected by a given age - so you can see exactly where waiting overtakes claiming early. For the full decision framework, see the Social Security Claiming Age Guide.
Step 1: Find Your Full Retirement Age SSA
Your full retirement age (FRA) comes from your year of birth. It is 66 for people born 1943-1954, rises in two-month steps to 66 and 10 months for 1955-1959, and is 67 for anyone born in 1960 or later. FRA is the age at which you receive 100% of your primary insurance amount.
Step 2: Reduce for Claiming Early SSA
Each month you claim before FRA reduces the benefit by 5/9 of 1% for the first 36 months and 5/12 of 1% for any additional months. With an FRA of 67, claiming at 62 is 60 months early, which produces the maximum 30% reduction (36 × 5/9% + 24 × 5/12%).
Step 3: Add Delayed Retirement Credits SSA
Each month you wait past FRA adds a delayed-retirement credit of two-thirds of 1% (8% per year) up to age 70. With an FRA of 67, waiting until 70 is 36 months of credit, a 24% increase. Credits stop at 70, so there is no reason to wait longer.
Step 4: Add Up Each Path and Find the Break-Even Confirmed
The tool multiplies each monthly benefit by the number of months you would collect it to your life expectancy, then finds the break-even age where the delayed path's cumulative total overtakes the early path's. An optional discount rate values future checks in today's dollars and pushes the break-even age later.

LMN Tax Inc. - Planning Notes
The break-even age does most of the work in our claiming conversations, but it is not the whole story. When a client is single and in poor health, a break-even in the low 80s is a strong argument to claim at 62 and enjoy the money while they can. When a client is a healthy married person who is the higher earner, we lean hard toward delaying to 70, because that larger benefit becomes the survivor benefit, and the odds that one spouse reaches the late 80s or 90s are simply too high to ignore.
People consistently underestimate their own longevity, and they underestimate it most as a couple. The break-even age the calculator shows is a hurdle, and we compare it against real mortality data rather than a gut feeling. For a 65-year-old couple, there is roughly a one-in-two chance at least one spouse lives past 90, which is well beyond the typical 80-to-82 break-even and pushes the math toward delaying the larger check.
We also separate the timing decision from the cash-flow decision. Some clients have the assets to delay but feel anxious spending down savings while they wait. We show them that delaying is not a gamble, it is buying a bigger inflation-adjusted, government-guaranteed annuity at a price no insurer can match. For a worker who is still earning before full retirement age, we add the retirement earnings test to the picture, because claiming early while working can temporarily withhold benefits that this calculator does not model.
Finally, we run the taxation of benefits alongside the timing. A larger age-70 check means more of it may be taxable once other retirement income, required minimum distributions, and provisional-income thresholds come into play. The timing decision and the tax decision are linked, and we never advise on one without checking the other.
When This Calculator Does Not Cover Your Situation
- Spousal and survivor benefits. This tool values your own retirement benefit only. A spouse's benefit (up to 50% of the worker's FRA amount) and a survivor benefit (up to 100% of the deceased's benefit) can change the optimal claiming ages for a couple.
- The retirement earnings test. If you claim before FRA and keep working, Social Security temporarily withholds $1 of benefits for every $2 (or $3 near FRA) earned above an annual limit. The withheld amount is later restored, but the timing is not modeled here.
- Taxes on benefits. Up to 85% of Social Security can be taxable depending on your other income. A larger delayed benefit can raise the taxable share; this comparison is pre-tax.
- Cost-of-living adjustments. COLAs raise every claiming option proportionally and roughly cancel out of the break-even, so the default omits them. Over a long retirement they do increase the absolute dollars.
- Medicare premiums. Part B premiums are usually deducted from the benefit and higher income can trigger IRMAA surcharges, neither of which is modeled.
- Disability or other entitlements. If you receive Social Security disability, claim a benefit on an ex-spouse's record, or are subject to special rules, your situation may differ from this standard retirement-benefit comparison.
Frequently Asked Questions
When should I claim Social Security: 62, full retirement age, or 70?
It depends on how long you expect to live relative to your break-even age. Claiming at 62 gives you a smaller check sooner; waiting until 70 gives you a much larger check later. The break-even age is the age at which the larger delayed checks catch up to and overtake the smaller early checks. If you expect to live past your break-even age (typically around 80 to 82 when comparing 62 to 70), delaying pays more over your lifetime. If your health or family history points to a shorter life, claiming earlier usually wins. Married status, a spouse's benefit, other income, and whether you are still working also matter.
What is the Social Security break-even age?
The break-even age is the age at which the total benefits from claiming later equal the total benefits from claiming earlier. Before that age, the early claimer is ahead on cumulative dollars because they started collecting sooner. After that age, the later claimer pulls ahead because each of their checks is larger. Comparing age 62 to age 70 for someone whose full retirement age is 67, the break-even age is roughly 80 to 81 in simple (undiscounted) dollars. If you expect to live past it, waiting wins; if not, claiming early wins.
How much does waiting from 62 to 70 increase my Social Security benefit?
For someone whose full retirement age is 67, claiming at 62 reduces the benefit by 30%, while waiting until 70 increases it by 24% through delayed retirement credits. That means the age-70 monthly benefit is about 77% larger than the age-62 benefit (1.24 divided by 0.70). On a $2,000 full-retirement-age benefit, that is roughly $1,400 a month at 62 versus $2,480 a month at 70. The increase comes from avoiding the early-claiming reduction and earning the 8%-per-year delayed credit between full retirement age and 70.
Does claiming Social Security later always pay more?
No. Delaying produces a larger monthly check, but you collect fewer checks because you start later. Delaying pays more in total only if you live past the break-even age. Someone who claims at 70 but dies at 75 collects far less in total than someone who claimed at 62. Delaying is essentially longevity insurance: it pays off most for people who live a long time, and it is most valuable for the higher earner in a married couple because the larger benefit can continue as a survivor benefit.
How does my full retirement age affect the decision?
Your full retirement age (FRA) is the anchor for both the early-claiming reduction and the delayed-retirement credit. For people born in 1960 or later, FRA is 67; for 1955 through 1959 it phases up from 66 and 2 months to 66 and 10 months; for 1943 through 1954 it is 66. The earlier your FRA, the smaller the maximum reduction at 62 and the more months of delayed credit you can earn before 70, which slightly shifts the monthly amounts but leaves the break-even ages in the same low-80s range.
Should married couples claim Social Security at different ages?
Often yes. A common strategy is for the lower earner to claim earlier to start some income, while the higher earner delays to 70 to maximize the benefit that will continue as a survivor benefit for whichever spouse lives longer. Because the odds that at least one spouse lives well into their late 80s or 90s are high, delaying the larger benefit is frequently worth more to a couple than the single-life break-even math suggests. Spousal and survivor benefits add layers this calculator does not model, so coordinate the two claims together.
Does this calculator account for cost-of-living adjustments and taxes?
The default comparison is in simple, undiscounted dollars and does not add an annual cost-of-living adjustment (COLA), because a COLA raises every claiming option proportionally and roughly cancels out of the break-even. The optional discount rate lets you see how the time value of money pushes the break-even age later. The tool does not model income tax on benefits, the retirement earnings test if you keep working before full retirement age, Medicare premiums, or spousal and survivor benefits. Use it for the timing decision, then check how much of your benefit is taxable separately.
What to Do Next
If You Expect a Long Life or Are the Higher Earner
Lean toward delaying. Read the Social Security Claiming Age Guide for the survivor-benefit strategy and how to bridge income while you wait to 70.
If You Also Have a Pension or IRA
A pension or IRA withdrawal raises the income that makes more of your Social Security taxable. Model the ripple with the Pension & Annuity Tax Calculator and plan withdrawals with the RMD Calculator.
If You Are Weighing a Pension Lump Sum Too
Coordinate the two decisions: compare a pension buyout with the Lump-Sum vs Annuity Calculator, since both choices hinge on longevity and break-even math.
