Ask workers when they'll retire and they say 65. The people who have actually retired stopped at 62, and 46% of them went earlier than they'd planned. Of those, 76% left for a reason they didn't choose, usually a health problem or a decision someone else made about their job. You can't control that part. You can get ahead of the decisions that come due before it, and retirement planning at 55 is when eight of them are worth knowing.
Plan for a date you may not get to pick
Among those who left early, 41% pointed to a health problem or a disability and 35% to changes at the company. Neither shows up on a calendar you control. So build the plan to work if the last paycheck lands at 62, and treat 63, 64 and 65 as extra years the plan doesn't lean on.
The same goes for the usual backup plan, part-time work. 75% of workers expect paid work to be one of their retirement income sources. Only 27% of retirees actually do part-time work, and three in four stopped working completely. A 58-year-old whose position got reorganized away, planning to pick up part-time work at 63, walks into that job market five years later with the same resume. The event that ends the job usually closes the backup plan too.
So take part-time earnings out of your spreadsheet and see whether the rest still stands. If it does, anything you earn later is a bonus. If it doesn't, you've found the real problem with a decade left to fix it.
Price the health insurance gap before you pick the date
Stop working before 65 and you buy your own health insurance until Medicare starts. That stretch got a lot more expensive at the end of 2025, when the enhanced premium tax credits expired and the old cliff at 400% of the federal poverty line came back. Under the enhanced credits, nobody paid more than 8.5% of their income for a mid-level plan, and the help tapered off gradually. Now there's a line, and a dollar over it the subsidy is gone. For 2026 it sits at about $62,600 for a single person and scales up with household size.
KFF ran the numbers on a 60-year-old earning $65,000 a year, 415% of the poverty line, just barely over. That person pays about $10,400 more a year for the same bronze plan, the cheap one. The premium goes from 2% of his income to 18% because his income landed over the line by a few thousand dollars.
The line is drawn on modified adjusted gross income, which for most purposes is close to what shows on your tax return. That's the part you have some say over: which year you take a capital gain, whether you do a Roth conversion, how much you pull from a traditional account once you can reach it without a penalty. Those levers are open at 55 and much harder to move at 60 with the date already set. Know which side of the line your income falls on.
Two timing rules that close behind you
Leave your employer in or after the calendar year you turn 55 and you can take money from that employer's 401(k) or 403(b) without the 10% early withdrawal penalty. It's called the rule of 55, and it does not apply to an IRA. Roll the 401(k) into an IRA on the way out and the exception is gone on every dollar you moved, locked up until 59½ again. The rule also waives only the penalty. The tax is the same, and a big withdrawal can push that year into a higher bracket. Ask whether your plan allows partial distributions, because plenty make you take the whole balance or nothing.
The second rule involves Medicare. It starts at 65, but it reads your tax return from two years earlier, so the income you report in the year you turn 63 sets your first premium. The standard Part B premium in 2026 is $202.90 a month. Above $109,000 for a single person or $218,000 married filing jointly, a surcharge is added, and these are cliffs too. Go over the first line by a dollar and it costs about $975 for the year, for each spouse on Medicare.
Run it backwards and 62 is the last year your income is invisible to Medicare. Anything big and optional is cheaper before then, like selling a rental, Roth conversions or exercising options. Since the health insurance cliff only bites in years you're buying your own coverage, the cheapest time for these moves is while you're still on an employer's plan. Put them on a calendar that ends at 62, and start it this year by asking how much room is left in your tax bracket.
Bigger contributions, smaller bills
In 2026 an employee can put $24,500 into a 401(k), or $32,500 with the catch-up at 50 and over. For four years only, ages 60 through 63, the total reaches $35,750 a year, then drops back. The bigger catch-up is optional for the plan, so send HR a two-minute email now.
The bill side is where you have the most control. 41% of retirees found their overall expenses were higher than expected, and nearly one in three people still working carry more than $25,000 of debt that isn't a mortgage. Say you carry a $1,200 monthly payment into retirement. To cover it on the usual 4% assumption, where you pull 4% of your portfolio each year, you need about $360,000 sitting there for that one payment. A year of maxing the 401(k) adds about $32,500. Retiring the payment can take $360,000 off what you need to have.
So shrink the bills first, then work out how to cover what's left. Line your payoff dates up against your retirement date and see which ones you can pull forward.
What separates comfortable retirees
Every regret survey lands in the same place. 76% of retirees regret not starting to save earlier, and 71% wish they'd saved more. Gallup asked a different question: do you have enough to live comfortably? 75% of retirees said yes. Then Gallup sorted the retiree answers by where the money comes from. With Social Security as the only real income, 60% are comfortable. Add one more source and it's 78%. With three or more, it's over 80%.
That's self-reported, and households with more sources also tend to have more money, so it describes the two groups and doesn't prove one more source raises comfort on its own. The sources are ordinary. Among retirees, 92% have Social Security, 56% have a pension of some kind, and 33% have real estate or rental property producing income. The other categories are just as ordinary: dividend-paying stocks, CDs, Treasuries, a bond ladder, a rental, or private mortgage notes where you're the lender on someone else's house.
Real estate is where I do this myself. I buy affordable houses in Ohio with private money and sell them to families on payments, so what I own pays me monthly instead of just carrying a price. Of everything listed here, only Social Security, a pension and a Treasury bond held to maturity pay you no matter what.
Building a second and third source takes working years, earnings you can redirect and time for the thing to start paying. At 55 you still have both. At 65 you're largely stuck with whatever you've built by then.
