Updated July 31, 2026. Quick answer: your financial life has about ten statutory birthdays — and most people know them only as round numbers, which is how mistakes happen: 59½ is an exact date, the rule of 55 runs on a calendar YEAR, the Medicare window opens three months before 65 (a month earlier if you were born on the 1st), and your RMD age depends on your birth year under a statute Congress mis-drafted for people born in 1959. Enter your birthdate and get your actual dates:

The three dates people get wrong
The rule of 55 is a year, not a birthday — separate from your employer any time in the calendar year you turn 55 and the 401(k) exception can apply; and the universal “roll it to an IRA” advice permanently destroys it. The Medicare window forgives nothing — miss the 7-month Initial Enrollment window without qualifying coverage and the Part B penalty is lifelong. And 1959 is a special case — SECURE 2.0’s text accidentally assigned that birth year BOTH RMD ages; the 2024 proposed regulations resolved it to 73, and the RMD basics guide covers what starting actually looks like.
The decisions behind the dates: when to actually claim Social Security · which account to draw first · giving from an IRA after 70½. The full chart in one glance: every retirement age, 50 to 75.
The dates are automatic. The decisions at each one are not.
Every date above opens a choice – claim or wait, roll or keep, convert or hold. The matching service below introduces you to advisers who pay to meet you.
Before you start, what actually happens. The form is run by Kapitalwise, our advisor-matching partner. It asks about nine questions — age, investable assets, location — then your name, email and phone number, and verifies the phone by text.
Kapitalwise sends your details to advisers who pay for the introduction, so expect calls and texts. Clear Money Guide is paid when you submit the form, whether or not you ever hire anyone. Nothing loads and nothing reaches Kapitalwise until you press the button.

The number that surprises people who bought a long time ago
Downsizing is the one home sale where the gain is usually large and the exclusion usually still covers it. A couple who bought in 1994 for $180,000 and sell at $760,000 with $46,000 of selling costs have a realized gain of about $534,000 before improvements. That is above the $500,000 joint cap — but decades of capital improvements are exactly what brings it back under, and most sellers have never added them up.
Improvements are the lever, and the records are the constraint
A new roof, an addition, a replaced HVAC system, new windows, a finished basement: these add to basis. Repainting and repairs do not. Thirty years of improvements on a family home routinely total six figures, and every dollar of it reduces the gain dollar for dollar. The practical problem is documentary, not legal — the seller who kept receipts pays less than the identical seller who did not.
Why downsizers should check the net investment income tax separately
A retiree with modest ordinary income can still be pushed over the 3.8 percent NIIT threshold by the sale itself, because taxable gain is net investment income. The thresholds are $250,000 on a joint return and $200,000 otherwise, written into Section 1411(b) as fixed figures with no indexing. A sale that produces $120,000 of taxable gain on top of $180,000 of other income crosses the joint threshold and picks up 3.8 percent on the part above it.
The move itself may change the tax
Downsizing usually means moving, and sometimes across a state line. Some states tax the gain the federal exclusion just removed. If the sale and the move are in the same year, the order of the two matters, and it is worth checking the destination state before signing.

Methodology
- Exclusion caps, the 2-of-5 test, the nonqualified-use allocation, the reduced-exclusion fraction and the depreciation carve-out are taken from the text of 26 U.S.C. 121. The 3.8 percent rate and its thresholds are from 26 U.S.C. 1411. Both were read on 2026-07-30.
- Section 121 caps and Section 1411 thresholds are written in the statute as fixed dollar amounts with no indexing mechanism, so they are built in. Long-term capital gain brackets ARE indexed annually, so your rate is an input rather than a lookup.
- Figures were computed by two independently written engines that agree to the cent, and the calculator on this page reproduces both exactly.
- Federal only. State treatment varies and some states do not follow the federal exclusion.
