Social Security Break-Even Calculator

How Social Security Is Calculated

Three steps stand between a lifetime of pay stubs and a monthly check, and only the last one is a choice. First, every year you ever paid Social Security tax on is restated in the wage terms of the year you turn 60 — $20,000 earned in 1990 is worth about $66,400 in 2024 wage terms, which is why an old salary is not the embarrassment it looks like. Second, the best 35 of those restated years are summed and divided by 420 months to give the Average Indexed Monthly Earnings. Third, that AIME runs through a formula and a claim-age factor.

The divisor is the cruel part. It is always 420, whether or not you actually worked 35 years, so a 30-year career has five genuine zeros averaged into it. Someone who retires at 45 after 23 years of work carries twelve empty slots. In this tool that penalty is priced directly: the FIRE preset shows how one more year of earnings, replacing the weakest year in the top 35, is worth about $107 a month for the rest of a life. Nobody with gaps should decide when to claim before seeing that number.

The 2026 Social Security bend points

The formula pays back a shrinking share of each additional dollar. Ninety cents of the first $1,286 of AIME, thirty-two cents of everything up to $7,749, and fifteen cents beyond that. On an AIME of $5,000 the three bands contribute $1,157.40, $1,188.48 and nothing, for a primary insurance amount of $2,345.80 — the figure used in every worked example on this page.

Those two numbers are derived, not decreed. Each year SSA takes the 1979 bases of $180 and $1,085 and scales them by wage growth, so the 2026 pair is those bases times the 2024 average wage index of $69,846.57 over the 1977 index of $9,779.44. The consequence worth knowing: the bend points that apply to you are locked by the year you turn 62 and never change afterwards. Turn 62 in 2026 and you keep $1,286 and $7,749 even if you file in 2034.

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

Waiting buys a bigger check and gives up years of smaller ones. The break-even is where the arithmetic turns over. Take the $2,345.80 PIA above, with a full retirement age of 67. Claiming at 62 pays $1,642 a month, at 67 pays $2,345, at 70 pays $2,908. Run the totals forward and the 62 line stays ahead until 80 years 5 months, when the 70 line passes it for good. Against full retirement age the crossing is earlier, at 78 years 8 months; between 67 and 70 it is later, at 82 years 6 months.

Reaching 90 turns a decision worth $146,208 on one date. Dying at 80 makes claiming at 62 the better call by $5,712 over the 70 strategy. Since nobody knows which they will do, a single break-even age is the wrong thing to optimise — it answers “what if I die on exactly this birthday” when the real question is what happens across every age you might reach.

That is what the survival-weighted view in the tool does instead. Each month's benefit is multiplied by the probability of being alive to receive it, using a mortality curve that differs by sex and self-reported health, and the 97 candidate months are ranked by the resulting expected value. The answer comes back as a specific month — 68 years 1 month, say — and it moves earlier for someone in poor health and later for someone healthy. Inflation, incidentally, barely enters into it: a cost-of-living adjustment lifts the early and late checks by the same percentage, so it shifts the crossing by only a month or two.

Full Retirement Age by Birth Year

The shorthand “62, 67 or 70” is wrong for anyone born between 1955 and 1959, whose full retirement age climbs in two-month steps. It changes the reduction, and therefore the check. The table prices each cohort on the same $2,345.80 PIA.

One more wrinkle catches people out. SSA treats you as reaching an age the day before your birthday, so a person born on 1 January 1960 is handled as a December 1959 birth and lands in the 66-and-10-months cohort rather than the 67 one. The same rule decides your first payable month: you must be 62 for a whole calendar month to be paid for it, which only births on the 1st or 2nd manage in their birthday month.

What Each Claiming Age Actually Pays

Reduction and credit run on different clocks. Before full retirement age you lose 5/9 of 1% a month for the first 36 months and 5/12 of 1% for every month beyond, which compounds into a 30% cut at 62 for an FRA of 67. After FRA you gain 2/3 of 1% a month — a flat 8% a year — and the meter stops on your 70th birthday. Filing later than 70 adds nothing, and SSA backdates an application by at most six months, so waiting past 70 is simply forfeited money.

Whole birthdays are a convention, not a rule. Every month in between is claimable, and the dial in this tool moves one month at a time because the right answer is rarely a round number. For context on the scale involved: the most anyone reaching full retirement age in 2026 can receive is $4,152 a month, while the average retired worker gets $2,071.

Social Security Spousal Benefits

The 50% rule is widely misread. A spouse does not receive half the worker's benefit on top of their own — they receive the larger of their own benefit or half the worker's PIA, which in practice means their own plus a top-up for the difference. Half of a $2,400 PIA is $1,200; a spouse with their own $900 gets $900 plus $300. A spouse whose own benefit already exceeds half the worker's PIA gets no top-up at all, and for dual-earner couples that is the usual outcome, which turns the decision back into two separate personal break-evens.

Timing works differently here too. The spousal top-up is reduced by 25/36 of 1% for each of the first 36 months claimed early and 5/12 of 1% beyond, so a spouse claiming at 62 against an FRA of 67 receives 32.5% of the worker's PIA rather than 50%. Critically, delayed retirement credits never apply to a spousal benefit — waiting past your own full retirement age for one gains precisely nothing. The top-up also cannot begin until the worker has actually filed, which is what makes a one-earner couple's two dates interlock.

Two rules close off the old strategies. Deemed filing, which covers everyone born on or after 2 January 1954, means claiming one benefit claims both — the restricted application that let people take a spousal while their own record kept growing is gone for this generation. File-and-suspend ended in 2016. A divorced spouse keeps more freedom: after a marriage of at least ten years, and while currently unmarried, they can claim on an ex-spouse's record once that person turns 62, without waiting for them to file.

Survivor Benefits: Why the Higher Earner Should Delay

When one spouse dies the household does not keep both checks. It keeps the larger one. That single fact reframes the whole decision for a married couple, because the higher earner is not really choosing their own retirement income — they are setting a floor under the survivor's income for however long that person lives, which for a wife outliving a husband is frequently a decade or more.

A survivor inherits delayed retirement credits. If the higher earner waits to 70, the 124% figure carries over to the widow or widower; if they claim at 62, the survivor is capped. The cap is the RIB-LIM rule: where the deceased had claimed before their own full retirement age, the survivor receives the greater of what the deceased was actually drawing or 82.5% of their PIA. On a $2,345.80 PIA that is the difference between a survivor check of $1,935 and one of $2,908 — $973 a month, for life, decided by a date. This is the cheapest life insurance most couples will ever be offered, and the premium is paid in patience rather than money.

The survivor's own timing has its own schedule, running roughly two years behind the retirement one: 66 for births through 1956, then two-month steps to 67 for 1962 and later. A widow or widower can claim from 60 at 71.5%, rising in a straight line to 100% at that survivor FRA. Because survivor and retirement benefits are separate claims, a survivor can take one early and switch to the other later — the one genuine sequencing strategy left standing after deemed filing. If the survivor's income gap is what worries you, our life insurance coverage calculator sizes the rest of it.

The 2026 Earnings Test

Claim before full retirement age while still working and SSA withholds $1 of benefit for every $2 earned above $24,480 a year, or $2,040 a month. In the calendar year you actually reach FRA the limit rises to $65,160 and the rate softens to $1 per $3, counting only what you earn in the months before your birthday. From the month you reach full retirement age the test disappears entirely, however much you earn. Someone earning $40,000 at 62 therefore has $7,760 withheld for that year.

Nearly everyone calls this a penalty. It is not one. At full retirement age SSA performs an adjustment of the reduction factor, recomputing the benefit as though you had claimed however many months were withheld later than you did. Someone who loses 25 months of benefit between 62 and 67 has their check recalculated on a claim date two years and a month later, lifting it from $1,642 to $1,889 a month permanently. The money comes back — though as a stream rather than a lump, taking roughly thirteen years of the higher payment to recover in nominal terms, which is why the test still argues for delaying if you plan to keep working anyway.

One exception helps mid-year retirees. In your first year of retirement a monthly test can apply instead of the annual one, so a month in which you earn under $2,040 and perform no substantial services in self-employment is paid in full regardless of what you earned earlier that year. Someone who leaves a $200,000 job in June and claims in July is not automatically zeroed out for the rest of the year.

Is Social Security Taxable?

Partly, for most retirees, and the mechanism has its own income measure. Provisional income is your other income, plus tax-exempt interest, plus half your Social Security. Below $25,000 for a single filer or $32,000 filing jointly, none of the benefit is taxed. Between there and $34,000 or $44,000, up to half becomes taxable. Above the upper threshold, up to 85% does — and 85% is a hard ceiling that no amount of additional income can push past.

A worked case: a single filer with $30,000 of other income and $28,140 of benefits has provisional income of $44,070, which makes $13,059.50 taxable — about 46% of the benefit. Municipal bond interest is the detail that surprises people most. It is genuinely free of income tax, and it still counts here, so a portfolio built around munis to stay in a low bracket can quietly drag more of the Social Security into the taxable band.

Two things are worth knowing about the thresholds. They have not been indexed since 1993, so inflation pulls more retirees over them every year with no legislative action at all. And the OBBBA senior deduction of $6,000 a head for those 65 and over, which phases out at 6% of modified AGI above $75,000 single or $150,000 joint, only runs through tax year 2028 — it lowers the tax on a benefit without changing the 85% rule underneath, and it is scheduled to vanish. Because withdrawals from a traditional 401(k) feed straight into provisional income while Roth withdrawals do not, the Roth versus traditional 401(k) calculator is the natural companion here.

What Happens in 2032

The 2026 Trustees Report, published on 9 June 2026, projects the retirement trust fund's reserves being exhausted in the fourth quarter of 2032, at which point continuing payroll tax revenue would cover 78% of scheduled benefits. Counting the disability fund alongside it moves the date to the third quarter of 2034 and the payable share to 83%. Both figures moved against retirees compared with the 2025 report, which had projected 2033 and 77% for the retirement fund alone.

This is a projection of what happens if Congress does nothing, not a scheduled cut, and every previous approach to a similar deadline produced legislation. But it belongs in the claiming decision because a cut does not fall evenly across strategies. Applying the 78% haircut to the $2,345.80 example pushes the 62-versus-70 break-even from 80 years 5 months out to 82 years 8 months — nearly two and a half years later, because the delayed strategy is the one leaning on checks that arrive after the cut date.

What it does not do is make claiming at 62 obviously right. A 22% reduction applies to everyone's benefit whenever they claimed, so it shrinks both sides of the comparison; it moves the break-even without inverting it. Anyone healthy and married still has the survivor argument intact. The honest use of the scenario toggle is to check whether your plan survives the bad case, not to let the bad case pick the plan.

How the Report Card Grades Your Plan

Six measures, weighted, turned into letters and averaged. Claim-age optimality carries the most weight because it is the decision the tool exists to inform, and it is scored against your own survival curve rather than a generic one.

The pairing of the first two dimensions is deliberate. Optimality never marks down early claiming that is genuinely right for someone in poor health — that person scores an A at 62. The second dimension then shows separately how that same choice performs if they turn out to be long-lived, which is the risk the first grade cannot see. Read together they give an honest answer rather than a flattering one. Coverage drops out entirely and its weight is redistributed if you leave essential spending blank, rather than failing you for a question you did not answer. Press E for the summary deck.

Methodology and Sources

Everything runs in your browser, and nothing you type is sent anywhere. A pasted earnings record is excluded from shareable links by design, so a link you send reproduces the result without carrying your income history.

2026 constants come from the SSA Federal Register notice Cost-of-Living Increase and Other Determinations for 2026 and the SSA 2026 fact sheet: a 2.8% COLA, a $184,500 taxable maximum, bend points of $1,286 and $7,749, earnings-test limits of $24,480 and $65,160, and $1,890 for a quarter of coverage. The wage-indexing series is SSA's national average wage index through 2024 at $69,846.57; the 2025 figure publishes around October 2026 and will be appended then. Medicare Part B is the CMS 2026 standard premium of $202.90 with a $283 deductible. Trust-fund figures are the 2026 Trustees Report of 9 June 2026. Taxation follows IRC section 86, with 2026 brackets and the $16,100 and $32,200 standard deductions from IRS Rev. Proc. 2025-32 and the OBBBA senior deduction as enacted for 2025 through 2028.

Survival weighting uses a Gompertz–Makeham mortality curve fitted to published SSA period life expectancies by sex at ages 62, 65, 70, 75, 80, 85 and 90, reproducing each of those anchors to within a fraction of a year. It is a smooth approximation of SSA's table rather than the table itself, and the health setting applies a labelled multiplier on top of it — useful for seeing which way your answer moves, not a medical projection.

Out of scope, and deliberately so: child and disability benefits, state income tax on benefits, and Medicare IRMAA surcharges, which are flagged where relevant but not modelled. The Windfall Elimination Provision and Government Pension Offset no longer apply — the Social Security Fairness Act repealed both, signed on 5 January 2025 and effective for benefits payable after December 2023. These are estimates, not SSA's official computation; confirm your own figures at ssa.gov/myaccount before you file, and note that an application can be withdrawn within twelve months using Form SSA-521 if you change your mind.
