How to Calculate Your Social Security Breakeven

The arithmetic behind the claiming decision --- one worked example, and the four adjustments that move the answer

June 6, 2026

Every conversation about when to claim Social Security eventually lands on the same word: breakeven. It gets used constantly and explained rarely. The idea is simple enough --- if you claim early, you collect smaller checks for longer; if you wait, you collect bigger checks starting later; and somewhere out in your late 70s or early 80s there is an age where the two paths cross. Before that age, the early claimer is ahead on total dollars collected. After it, the patient claimer pulls ahead and never looks back. Where exactly that crossover sits --- and whether you should expect to live past it --- is the breakeven question.

Last month I wrote about why the "always wait until 70" default oversimplifies the claiming decision. This piece is the companion to that one. Rather than argue about which claiming age is right, I want to show you the actual arithmetic --- where the numbers come from, how to run the calculation yourself, and which assumptions quietly drive the answer. By the end, you should be able to compute a breakeven on the back of an envelope and, more importantly, know what the number does and does not tell you.

A word on why this matters. Nearly 71 million Americans receive Social Security benefits, and the 2026 cost-of-living adjustment of 2.8 percent took effect with January's payments. ¹ For most retirees this is the largest piece of guaranteed lifetime income they will ever own, and the claiming election is one of the few levers that permanently changes its size. By the late 80s, the gap between the earliest and latest claiming paths in the example I walk through below runs well into six figures of cumulative benefits. That is real money, and the breakeven calculation is the first tool for thinking about it clearly.

Social Security began paying monthly retirement benefits in 1940, and for the first several decades the rules around claiming age were comparatively static. ² The architecture we plan around today --- a full retirement age of 67, early claiming from 62, delayed credits through 70 --- is largely the product of one law: the Social Security Amendments of 1983. ³ Facing a near-term financing crisis, Congress adopted a package built on the recommendations of the Greenspan Commission, and two provisions of that package matter enormously for the claiming decision. First, the amendments scheduled a gradual increase in the full retirement age from 65 to 67, phased in between 2000 and 2027 --- a forty-four-year runway from enactment to full effect. Anyone born in 1960 or later has a full retirement age of 67. ⁴ Second, the amendments raised the delayed retirement credit from 3 percent per year to 8 percent, phased in beginning in 1990, with the full 8 percent credit applying to everyone born in 1943 or later. ³

Those two changes redrew the claiming math. As the full retirement age moved from 65 to 67, the reduction for claiming at 62 deepened from 20 percent to 30 percent. ^{3 4} And the richer delayed credit made waiting meaningfully more valuable than it had been for earlier generations --- 8 percent per year is a different proposition than 3 percent. SSA's own policy research describes the modern 8 percent credit as roughly actuarially fair for a worker of average longevity, which is precisely why the breakeven framing exists at all: the system was rebuilt so that, on average, no claiming age is a free lunch. ³ The dollars are meant to come out roughly even for the average person. The planning opportunity comes from the ways your household is not average.

Everything starts from the primary insurance amount, or PIA --- the monthly benefit you would receive by claiming exactly at full retirement age. Claim earlier and a formula reduces it: 5/9 of one percent for each of the first 36 months before FRA, and 5/12 of one percent for each month beyond 36. ^{4 5} For a worker with an FRA of 67 who claims at 62 --- 60 months early --- that works out to exactly 30 percent: you receive 70 percent of your PIA, permanently. Claim later and the delayed retirement credit adds roughly two-thirds of one percent per month, 8 percent per year, with the credit fully accrued at age 70. ⁶ Delaying from 67 to 70 produces a benefit of 124 percent of PIA --- and there is no benefit to waiting past 70, because that is where the meter stops. ⁶

Figure 1 lays out the full schedule for an FRA-67 worker at each claiming age from 62 to 70, both as a percentage of PIA and in dollars for a worker with a $3,000 PIA --- the example I will carry through the rest of this piece. The range is wide: $2,100 per month at 62, $3,000 at 67, $3,720 at 70. The age-70 check is 77 percent larger than the age-62 check, for the identical earnings record.

For scale, here is what the 2026 numbers look like at the top of the system. A worker who earned at or above the taxable maximum every year of a full career and retires at full retirement age in 2026 receives $4,152 per month. The same career record claimed at age 62 in 2026 pays $2,969; claimed at age 70 it pays $5,181. ⁷ And benefits, once claimed, are adjusted for inflation each year --- the 2026 cost-of-living adjustment was 2.8 percent, following 2.5 percent in 2025. ¹ That indexing matters for how we set up the breakeven calculation, and I will come back to it.

Figure 1: Monthly benefit by claiming age for a worker with full retirement age 67, as a percentage of the primary insurance amount and in dollars for a $3,000 PIA. Reduction is 5/9 of 1 percent per month for the first 36 months before FRA and 5/12 of 1 percent per month beyond; the delayed retirement credit adds 8 percent per year through age 70.

The breakeven question compares two claiming ages and asks: at what age does the cumulative total collected under the later claim catch up to the cumulative total collected under the earlier claim? The calculation takes four steps, and none of them requires anything beyond division.

Let's look at the 62-versus-67 decision for our $3,000-PIA worker. Step one: compute the early claimer's head start. Claiming at 62 instead of 67 means collecting 60 monthly checks of $2,100 before the age-67 claimer receives anything --- a head start of $126,000. Step two: compute the monthly gap once both are collecting. From 67 onward, the later claimer's check is $3,000 against $2,100, a gap of $900 per month. Step three: divide the head start by the gap. $126,000 divided by $900 is 140 months --- eleven years and eight months. Step four: add that to the later claiming age. Sixty-seven plus eleven years and eight months puts the breakeven at age 78 and 8 months. Live meaningfully past 78, and waiting until 67 wins on raw dollars. Pass away before it, and claiming at 62 collected more.

Run the same arithmetic on the other two comparisons and the pattern emerges. Comparing 62 against 70: the head start is 96 checks of $2,100, or $201,600; the monthly gap is $1,620; and the crossover lands a little past age 80. Comparing 67 against 70: a $108,000 head start against a $720 monthly gap puts the breakeven at 82 and a half. Figure 2 shows all three paths and their crossover points. A useful and underappreciated property of this math: the breakeven ages do not depend on the size of your benefit. Double the PIA and you double both the head start and the monthly gap --- the months required to catch up are unchanged. The crossover is set entirely by the claiming ages being compared and the reduction and credit schedule, which is why the ages in Figure 2 apply to a $1,500-PIA household just as well as to a $4,000 one.

A breakeven calculation is a footrace between a slow runner with a head start and a faster runner who starts late. The question is never whether the faster runner closes the gap --- given enough track, she always does. The question is where on the course it happens, and whether the race lasts that long. Everything else in the claiming conversation is, one way or another, an argument about the length of the track.

One housekeeping note before we adjust the simple math: I ran the whole example in today's dollars and ignored cost-of-living adjustments. That is not as sloppy as it sounds. COLAs apply proportionally to both paths --- the early claimer's $2,100 and the later claimer's $3,000 receive the same percentage adjustment each year --- so inflation indexing largely washes out of the comparison. The simple version is a fair first cut. What does not wash out is the time value of money, which is the first of the four adjustments below.

Figure 2: Cumulative benefits collected by claiming age for an illustrative worker with a $3,000 PIA and FRA 67, in today's dollars with no COLA, taxes, or investment of benefits. Crossovers: 62 vs. 67 at age 78y 8m; 62 vs. 70 a little past 80; 67 vs. 70 at 82y 6m. Breakeven ages are independent of the PIA level.

Time value: a dollar at 63 is not a dollar at 85

The simple breakeven treats every dollar equally whenever it arrives. But the early claimer's dollars show up sooner, and dollars that arrive sooner can be invested --- or, just as meaningfully, can spare your portfolio from withdrawals it would otherwise have to fund. The honest way to handle this is to discount both benefit streams at a real, after-inflation rate and find where the present values cross. The effect runs in one direction only: every assumption of positive real return pushes the breakeven later. Using our same example and comparing 62 against 70, the crossover sits a little past 80 with no time-value assumption, moves to roughly 81 and a half at a 1 percent real rate, to nearly 83 at 2 percent, and past 84 at 3 percent. Figure 3 shows the full sensitivity for all three claiming comparisons. The takeaway: each percentage point of real return you genuinely expect to earn on early benefits pushes the breakeven out by roughly a year to a year and a half. If the alternative to claiming is spending down a conservatively invested reserve, the appropriate rate is low and the standard breakeven is close to right. If early benefits would genuinely reduce withdrawals from a long-horizon portfolio, the case for early claiming strengthens at the margin.

Longevity: the only variable that decides the race

Breakeven ages mean nothing without a view on how long the race runs. The Social Security Administration's own planning tools put average remaining life expectancy for a man reaching 65 in 2025 at about age 84.3, and for a woman at about 86.9. ⁸ Set those against the crossovers above and the textbook conclusion follows: for a single person in average health, most of the breakevens fall before average life expectancy, which is why delay so often wins on paper. But averages conceal exactly the information that matters. Family history, current health, occupation --- these shift individual longevity by years in either direction, and the breakeven framework is only as good as the longevity assumption you feed it. This is the first conversation I have with clients weighing the decision, and it has nothing to do with spreadsheets.

The survivor benefit: married couples are running a different race

For married couples, the most important adjustment is that the higher earner's claiming decision is not measured against his or her own life expectancy at all. When the first spouse dies, the survivor --- at his or her own full retirement age --- steps up to 100 percent of the deceased spouse's benefit, including every delayed retirement credit the deceased earned. ⁹ The higher earner's larger check survives the first death and keeps paying for as long as either spouse is alive. That means the higher earner's breakeven should be measured against the second-to-die life expectancy of the couple, which runs past either spouse's individual expectancy. Delay on the higher earner's record is longevity insurance on two lives, purchased at one price. The lower earner's record, by contrast, stops mattering at the first death --- which is why the asymmetric strategy I described last month, delaying the higher earner while claiming the lower earner earlier, so often beats applying one rule to both spouses.

Working, taxes, and the windows around the claim

Two practical rules change the math for anyone claiming before full retirement age while still working. The earnings test withholds $1 of benefits for every $2 earned above $24,480 in 2026 for a claimant who is under FRA all year; in the calendar year you reach full retirement age the threshold rises to $65,160, and the test no longer applies once you are past FRA. ⁷ For a client still drawing meaningful wages at 62, early claiming often accomplishes far less than the simple breakeven suggests. Taxes cut in the same direction. Depending on your other income, a portion of Social Security benefits becomes taxable, and starting benefits early raises taxable income in exactly the years that are otherwise the cheapest for Roth conversions and low-bracket capital-gains harvesting. The breakeven arithmetic prices none of this --- it compares gross benefit dollars, not after-tax outcomes inside a real financial plan. For households with large pre-tax retirement balances, the value of keeping the 62-to-70 window clear for conversions is frequently larger than the actuarial difference between claiming ages.

One structural note belongs here as well. The 2025 Trustees Report projects that the Old-Age and Survivors Insurance trust fund's reserves deplete in 2033, after which continuing program income would cover 77 percent of scheduled benefits; the combined retirement and disability funds reach that point in 2034, at 81 percent. ¹⁰ I am not predicting a benefit cut --- Congress legislated its way out of the very same corner in 1983, which is where this piece began. But a client who weighs a sure check today against a larger scheduled check eight years out is not being irrational. The right response is to treat the depletion dates as one input among several, rather than either ignoring them or panicking over them.

Figure 3: Breakeven age for each claiming comparison as a function of the assumed real (after-inflation) discount rate, computed on the same $3,000-PIA example. Dotted lines mark SSA average life expectancy at 65 (84.3 men, 86.9 women). Higher assumed real returns push every breakeven later.

The breakeven calculation is the right place to start and the wrong place to stop. It is an input, not an answer. The number tells you where the paths cross under a set of assumptions --- it cannot tell you your health, your spouse's claiming interaction, your tax picture in the bridge years, or what your portfolio needs to look like to fund a delay comfortably. We treat the claiming election the way we treat every long-horizon planning lever: multi-year, household-specific, tax-aware rather than tax-driven, and coordinated with the rest of the balance sheet.

If you are within a few years of 62, the productive exercise is to run this arithmetic with your real numbers --- your PIA and your spouse's, straight from your Social Security statements --- and then stress the assumptions honestly. What real return would the early dollars actually earn? Whose life expectancy actually governs each record? What does the claim do to the conversion window? That conversation belongs with us, your CPA, and, where estate questions intersect, your attorney. This piece is the framework; the decision is fact-specific.

Social Security claiming is one of the few retirement decisions that is both largely irreversible and entirely within your control. The breakeven calculation will not make the decision for you, but it converts a vague argument about patience into a concrete one about ages, dollars, and assumptions --- and decisions improve when the assumptions are on the table. Our team will continue monitoring the annual Trustees Report, the COLA cycle, and any legislative response to the 2033 depletion projection, and we will update this framework if the rules underneath it move.

All my best,
