The part of your pay you never see
Ask how much income you need to retire at 55 and the obvious answer is your monthly spending. Add up the bills, call that the number. At 50, 55, or 60, that number comes up short.
Part of what your employer pays you never shows up on your pay stub. On a family health plan, the company covers about three quarters of the premium. KFF surveys these plans every year, and the average family premium is $26,933. Workers pay $6,850 of it. The employer covers the other $20,000.
Stop working early and that whole bill is yours until Medicare. And it's only one of two costs that move with the age you stop. The second is bigger, and it decides whether your savings are even allowed to pay you yet.
One couple, three ages
To keep the numbers comparable, I'll use one household. A couple, both the same age, with bills of $7,000 a month including taxes. That's everything except health coverage, because the job handles that today. Every figure is at current prices.
A plan you buy on your own is priced by age. Under federal rules, a 64-year-old can be charged up to three times what a 21-year-old pays for the exact same plan. KFF puts the average standard silver plan for a 60-year-old at $15,914 this year with no subsidy. For a couple, that's about $2,650 a month. At 55, the same plan runs about $2,180 for the two of them. At 50, around $1,750. It rises every birthday until Medicare at 65.
Stop at 60 and you pay your own premium for about five years: roughly $168,000. Stop at 55 and it's 10 years: $310,000. Stop at 50 and 15 years of premiums runs about $425,000. Those are for two people. If you're single, cut them in half; the rest works the same. And that's the premium only. Deductibles and co-pays come on top.
So the couple's monthly number is $7,000 plus the health plan: about $8,750 if they stop at 50, $9,180 at 55, and $9,650 at 60. The youngest age starts lowest because the plan is cheaper then. It just runs longer, and by 64 it reaches the same $9,930 a month.
Which money is allowed to pay you
The bigger difference between these ages has nothing to do with spending. It's about access. If most of your savings sit in a 401(k) or an IRA, there's a date stamped on them. Take money out before 59½ and the IRS adds a 10% penalty on top of the income tax you already owe. Stop at 60 and you're past that date. Every dollar you saved can pay you.
Stop at 55 and there are four and a half years to get across. For this couple, that's about $500,000 of spending before the accounts open. There is a rule that helps: leave your job in the year you turn 55 or later, and you can take money from that employer's 401(k) without the penalty. The calendar year is what counts: leave in January, turn 55 in December, and it still applies. But it only covers the plan at the job you're leaving. Not an IRA, and not an old 401(k) from a past employer.
Stop at 50 and it's a different situation. Nine and a half years to get across, about $1 million of spending. The age 55 rule is no help: leave at 50 and it never applies to that 401(k), even after you turn 55. Another IRS exemption lets you take fixed payments on a set schedule with no penalty. The catch is the lock-in. Start them at 50 and you can't change them until 59½. Change early and the penalty comes back on every payment you already took, plus interest.
Roth IRA contributions can come out any time with no tax and no penalty. The growth has to wait; the money you put in doesn't. After that, what's left is money outside retirement accounts: a regular brokerage account, cash in the bank, and anything you own that pays you an income on its own.
This part I know firsthand. I left the Air Force at 33, more than 26 years before any retirement account would pay me without a penalty. I didn't need one. I had rentals covering my bills, and rental income has no age rule. Income from something you own outside a retirement account pays at any age, whether it's a rental house, a private mortgage note, or dividends in a brokerage account. I'm a real estate investor, not a financial advisor, and I'm not telling you to buy rentals.
Where the money sits matters more than how much
Stopping at 60 is the easiest of the three. It also means 10 more years of work. Stopping at 50 can work too, but nearly all of those first nine and a half years have to be paid by money sitting outside retirement accounts.
So at 60, the question is how much you've saved. At 50, it's where it sits. Picture two couples with $1.5 million each at 50. One has all of it in 401(k)s. The other has $1 million outside, in a brokerage account and property that pays rent. The first couple can't touch theirs before 59½ without the penalty or the payment lock. The second can reach two thirds of theirs the day they stop working.
How long the income has to last
Plan out to 95. Stopping at 60 means 35 years of income, 55 means 40, and 50 means 45. Prices went up 3.4% in the 12 months through August, by the official numbers. I'll use 3% to keep it simple. At 3%, $7,000 a month of bills grows to about $19,700 a month over 35 years, and $26,500 over 45. Turn that around: a $7,000 check that never goes up buys, after 45 years, what about $1,850 buys today. None of that shows up in the first-year number.
Here's how I handle it with my own money. My bills are covered by income that shows up every month without me selling anything. I keep a cash buffer so one late payment doesn't touch the bills. Everything else sits in growth investments that I leave alone. None of it gets sold for groceries, so it has all those years to keep up with prices. Twenty years in, the same $7,000 in bills costs about $12,600 a month. The income side pays today's bills; the growth side covers the difference as it opens up. The younger you stop, the more work the growth side has to do, and the more it matters that you never have to sell it in a bad year.
Using the years you have left
If you're still working toward one of these ages, the remaining years can be set up for it. Aiming for 60, your 401(k) can do most of the lifting, since those accounts open before you stop. The main jobs left are five years of health premiums and keeping part of the money growing. Aiming for 55, it matters which 401(k) holds the money. The age 55 rule reaches the plan at the job you leave from, so that's the account to build while you're there. Aiming for 50, your next dollars have to go somewhere you can reach at 50: Roth IRA contributions if your income allows them, a regular brokerage account, or something that pays income outside a retirement account.
A big balance can still be the wrong shape for the age you picked. At 50, a dollar in a brokerage account can pay you. A dollar in a 401(k) mostly just has to wait.
