Your Social Security claiming decision, in the open

The largest-dollar decision most retirees ever make, modeled as arithmetic, not advice: what your benefit is at 62, at full retirement age, and at 70, what your spouse keeps if you go first, and the traps that quietly cost money. Free, and your numbers never leave your device.

What this does, and what it will not do

When you claim Social Security is one of the biggest money decisions of your life, and it is nearly impossible to un-make. This page lays out the arithmetic so you can see the trade-offs for your own situation. It shows you the numbers; it does not pick for you. There is no "right age" printed here, because the right age depends on your health, your savings, your spouse, and what you value — and only you can weigh those.

Want to put in your own numbers? Use the free claiming calculator. It runs entirely on your device — nothing you type is sent anywhere.

The three anchor ages

You can start your own retirement benefit any month from 62 to 70. Three ages anchor the range:

62 — the earliest. Starting here permanently reduces each check, because you will receive more of them.
Full retirement age — 66 to 67 depending on your birth year. Here you receive 100% of your primary insurance amount, the figure your statement shows.
70 — the latest worth waiting for. Each month you delay past full retirement age adds a delayed-retirement credit, up to 8% a year, and the credits stop at 70. Waiting past 70 adds nothing.

See the exact amounts for three birth years, and put in your own, on the calculator.

Break-even is a fact, not an argument

People are often told a "break-even age" — the age at which the larger, later checks have added up to the same total as the smaller, earlier ones. It is real arithmetic, and the calculator shows it. But a break-even age is a fact about dollars added up, not a reason to choose either path. It assumes the same cost-of-living adjustments apply to both, and it counts only nominal dollars — not interest, not taxes, and not how long you actually live. Read it as one input among several.

Every benefit also rises each year with a cost-of-living adjustment — 2.8% for 2026 — and that raise applies at whatever age you claim, so it does not tip the choice one way or the other.

The part almost no one hears: the survivor floor

For a married couple, the higher earner's decision is not mainly about their own break-even. Here is the mechanism. When one spouse dies, the household does not keep both benefits — it keeps the higher of the two. So the monthly amount the higher earner locks in becomes the amount whoever outlives the other lives on, for the rest of their life.

Framed as "your break-even is 81," waiting reads like a gamble. Framed as "this is the monthly amount your spouse keeps if you go first," the same delay reads like insurance. It is the same arithmetic — the calculator shows the floor at each claiming age for a real couple. Whether that trade fits your household is yours to decide; we only show you both floors.

The spousal trap: no credit for waiting

A husband or wife can claim a spousal benefit worth up to 50% of the worker's primary insurance amount, reached at the spouse's own full retirement age. Here is the trap: a spousal benefit earns no delayed-retirement credits. It is worth the same 50% whether it starts at full retirement age or years later. People delay both benefits, thinking each grows — and the spousal half simply does not. Delaying a spousal claim past full retirement age is pure loss.

Divorced-spouse benefits — widely unclaimed

If a marriage lasted at least 10 years, a divorced person may be able to claim on their ex-spouse's record, subject to other rules — and it does not affect the ex or their current family. This benefit is badly underused, mostly because people have never heard of it. This is general education, not a decision about whether you personally qualify; the place to confirm eligibility is ssa.gov.

The earnings test: withheld, not forfeited

If you claim before full retirement age and keep working, some benefits are withheld: $1 for every $2 you earn over $24,480 a year, or $1 for every $3 over $65,160 in the year you reach full retirement age. Here is the part that is almost universally misunderstood: withheld benefits are not lost. At full retirement age Social Security recomputes your benefit to credit the months that were withheld. It feels like a penalty; it is really a delay.

Three traps that arrive later

Claiming interacts with taxes and Medicare in ways that surprise people years afterward. Each has a face in the rogues' gallery:

Benefit taxation — whether your benefit is taxed depends on your provisional income. Above $25,000 for a single filer or $32,000 filing jointly, up to 50% of your benefit can become taxable; above $34,000 single or $44,000 joint, up to 85%. These dollar lines are fixed in law and are not adjusted for inflation. Meet the Tax Torpedo.
Medicare IRMAA — a surcharge set by your income from two years earlier. A big income year can raise your Medicare premium two years later. The 2026 income lines were not confirmed when this was written, so we do not print them. Meet the IRMAA Cliff.
The widow's cliff — in the year a spouse dies, one benefit ends and the survivor starts filing single, landing in tighter brackets and lower Medicare thresholds at once. Meet the Widow's Cliff.
