When can I retire? Ages 55, 60, 62, 65 and 67 compared

When can I retire? People expect one age as the answer, and there is not one — there are five. American retirement is not a single gate but a row of doors that unlock at 55, 59½, 62, 65, 67 and 70, and each one opens something different: penalty-free access to your own savings, the first Social Security check, Medicare, your full benefit, your maximum benefit. You can walk through some early and others late. Here is what unlocks at what age — and then the separate question that decides most real retirements: whether the money holds up if you go through the early doors.

The ages, one by one

The milestone ages of US retirement, from IRS, Social Security Administration and Medicare rules. None of these ages is a legal requirement to retire — they are the ages at which the system changes its prices.

Read that table once more and notice what it never says. Nothing in it makes you retire at any age, and nothing forbids retiring at 58 or 71. What age can you retire at, legally? Any age at all. The real question the ages answer is narrower: at what age do you retire without paying penalties, discounts and gaps for the privilege? Each early door has a price tag, and the prices are knowable in advance.

The money test: what leaving at 60 costs a saver

Run a simple saver through it. Someone saving $500 a month from age 30, at an assumed 7% annual return compounded monthly, reaches about $609,986 by 60 — and about $1,048,272 by 67. Retiring at 60 does not just remove seven years of contributions; it surrenders roughly $438,287 of growth on money already saved, and then asks the smaller pile to fund seven extra years of spending. Early retirement is a double hit: fewer years in, more years out. That arithmetic — not any rule — is why the answer to “when can you retire” is so often later than people hope.

Then there is the bridge. Retire at 60 and, on spending of $64,000 a year, the two years before the first possible Social Security check require about $128,000 straight out of savings — before the reduced check even becomes available at 62. And from 62 to 65 you hold a reduced check but not yet Medicare, which brings me to the cost almost every early-retirement plan under-prices:

So — what age do you retire at?

My honest framework is three checks, in this order. First, access: which doors are open — can you reach your savings without the 10% penalty, via the rule of 55 or by being past 59½? Second, income: which checks exist yet — Social Security from 62, Medicare from 65 — and what fills the space before them? Third, endurance: does the projection, run honestly with inflation switched on, still hold at age 90 and beyond? When all three checks pass at an age, that age is a real answer. Our retirement calculator is built for the third check: set the retirement age to 60, then 65, then 67, and watch the projected balance and monthly income move — the “When can I retire?” section reads the result against exactly these milestones.

Retiring in stages: the part-time bridge

There is a fourth answer between retiring at 60 and working full-time to 67, and for many households it is the one that actually happens: downshift instead of stopping. Part-time earnings from 60 to 65 change all three of my checks at once. For access, earnings that cover most of your spending let the retirement accounts stay shut until the penalties are gone. For income, part-time work is what makes delaying Social Security practical — every year you can postpone the claim moves it up the published adjustment table, from 70% of full benefit at 62 toward 100% at 67 and beyond. For endurance, five years of half-withdrawals instead of full ones is a far gentler demand on the portfolio than five years of full spending.

Two cautions belong in this plan. If you claim Social Security before full retirement age while still earning above the SSA’s annual limit, part of the benefit is withheld — it is credited back after full retirement age rather than lost, but it surprises people. And once you enroll in Medicare at 65, you can no longer contribute to a health savings account, so HSA contributions belong in the years before enrollment, not after. Neither caution kills the staged retirement; both are cheaper to know at 58 than to discover at 63.
