How to turn your retirement savings into a monthly paycheck
Key takeaways
- Start with what you spend in a month, after taxes. Your old salary is the easier number to grab, and it'll inflate your target well past what you need.
- Once Social Security and a pension are switched on, they arrive on their own schedule. Write down what each one deposits after any Medicare premium and withholding come out, and what day of the month it hits.
- Subtract those deposits from your spending number. What's left over is what your portfolio has to send you every month.
- If that money comes out of a traditional IRA, it's taxable, and if you have tax withheld it comes out before the deposit does. So at a 20% assumption, landing $5,000 in checking means pulling $6,250 out of the account.
- Set the withholding percentage knowing it's a guess in year one, since the year you retire is part working year and part retired year. Check it in the fall, while there's still time to fix it.
For the last thirty or forty years, you might've had "payday" written in your calendar. It came on a set day, and you could count on it without fail.
Once you retire, that goes away. Until you start Social Security, there might be no income at all dropping into your checking account on a regular basis. When you leave your job, what you're most likely left with is this nebulous balance. Yeah, it looks nice, and if you've been a diligent saver and lived within your means it might be over six figures. But the natural question I hear at this point (or even before retiring) is:
How do I turn my nest egg into a monthly paycheck in retirement?
This post is all about how to think about building a system that answers that question.
Start with what you spend
The first step is figuring out what you spend in a month, after taxes.
Your gross salary is a different number, and a bigger one. It had payroll taxes, 401(k) contributions, and health insurance premiums coming off the top before any of it hit your bank account. So if you were earning $200,000 a year and living on $10,000 a month, the $10,000 is what we're working with.
Out of that number, separate the essential from the discretionary spending. When a bad market year shows up you might have to tighten your belt a bit, and that's much easier to follow through on when you've already decided what expenses can be cut, and which can't.
Your spending also won't be the same every month. Property taxes, insurance premiums, a new roof, replacing a car, or the trip you take every year are all things to plan around, but none of them hit on a monthly schedule. You can divide the annual total by twelve and roll it into your monthly number, or you can keep a separate "goals" bucket and fund that more periodically. What doesn't work is letting them land as a surprise.
For the rest of this post, let's say a married couple lands on $10,000 a month.
Subtract what already shows up
Not all of that $10,000 has to come out of your portfolio.
Social Security is usually the biggest piece. It's paid monthly, and for most retired workers the payment day is the second, third, or fourth Wednesday, depending on your birth date. So if you're married, you might end up with two Social Security deposits landing on two different Wednesdays.
What you want to write down is the amount that hits your bank account. If you're on Medicare, those premiums usually come out of the benefit first, and if you elected to have federal tax withheld, that comes out too. When either one applies, your award letter and your bank statement will show two different numbers.
Then do the same for a pension, an annuity that's already paying out, rental income, or part-time work. For each one you want two things: what lands, and what day it lands.
If $3,500 shows up on the third Wednesday but your mortgage clears on the first, your checking account is carrying the household for eighteen days in between. So keep enough of a cushion in checking to ride out the longest of those gaps, and the dates stop mattering.
| Monthly cash flow | Amount |
|---|---|
| After-tax spending target | $10,000 |
| Social Security deposits | ($3,500) |
| Pension deposit | ($1,500) |
| After-tax portfolio gap | $5,000 |
So the portfolio is on the hook for $5,000 a month, or $60,000 a year.
That number tells you how big the monthly transfer has to be. It doesn't tell you whether your portfolio can keep sending it for the next thirty years, which depends on your balance, how long the money has to last, what it's invested in, and how much your spending could flex in a bad year. I walked through how I think about those variables in Do you have enough to retire?.
Add the taxes back on top
This is the part I spend the most time on, and that's probably because of the seat I sit in. I build the plan, and when I also prepare the tax return, I'm the one who reconciles withholding in April.
Everything so far has been in after-tax dollars. The $10,000 is what you spend, and the $5,000 is what has to land in your checking account. But money coming out of a traditional IRA or 401(k) is generally ordinary income, unless part of it is money you already paid tax on. If you have tax withheld, it comes out before any of it reaches your bank, which means asking your custodian for $5,000 doesn't put $5,000 in checking.
To get to the deposit you want, you work backwards. Divide by one minus whatever tax rate you're assuming. At 20%:
$5,000 ÷ (1 − 0.20) = $6,250
| Monthly IRA distribution | Amount |
|---|---|
| Gross distribution | $6,250 |
| Illustrative tax withholding or reserve | ($1,250) |
| Amount deposited in checking | $5,000 |
Over a year, that's $75,000 coming out of the IRA to fund $60,000 of spending. Tax on that money was always coming. The $15,000 here is just this illustration's version of it, and your number will be different. The question is whether you planned for it in January or found out about it in April.
I picked 20% because it makes the math easy to follow. It isn't a recommended withholding rate and it isn't anybody's actual bracket.
What you'll owe
Your real number depends on which account the money comes from, what else is on the return, your deductions, what state you live in, and plenty of other factors beyond the scope of this post.
Then there's Social Security. How much of your benefit gets taxed depends on how much other income you have. So when you pull one more dollar out of the traditional IRA, you might drag another piece of your Social Security into taxable income right along with it, and that dollar ends up costing you more than your bracket would suggest.
Getting your rate right takes a projection of the whole return.
How taxes get paid
You have a couple of options. You can elect a withholding percentage on the distribution, and the custodian holds that money back, sends it to the IRS, and reports it on the 1099-R you get in January. Most custodians can withhold for your state too, though that depends on the state and the payer. It works the same way your employer's payroll did, except you're the one choosing the percentage.
If you don't make an election, a default rate applies, and there's no reason to expect the default to match what your household owes. And your custodian only sees the distribution it's sending. It has no idea what else is on your return, so if you have other income that needs covering, the percentage you elect has to account for it.
Withholding isn't the only route, though. Federal income tax is pay as you go, and you can meet that with quarterly estimated payments instead, or with a mix of both.
Set up the transfer
Chances are almost nothing in your IRA is sitting in cash. It's funds or stocks, and a transfer can't move an investment into your bank account. So the money makes a few stops on the way:
- Something gets sold, or you turn off automatic reinvestment so dividends and interest land as cash instead.
- That cash sits in a holding account inside your IRA. Depending on the custodian it might be called a settlement fund, a core position, or a money market.
- You take the distribution out of that holding account, and this is where withholding comes out.
- What's left transfers to your bank.
Some custodians will sell automatically to fund a scheduled transfer. Others only send what's already sitting in that holding account, which means the selling has to happen first. Worth finding out which one yours does before the first transfer runs.
From there it's just how often you want it. Once a month is simpler to reconcile, twice a month feels closer to the paycheck you had for thirty years, and either one runs on its own once you've set it up.
Your first year is going to be messy
The withholding percentage you pick in month one is a guess, because the year you retire is part working year and part retired year, and there's usually a final paycheck, a payout of unused time off, maybe a bonus landing after your last day. This is where a year-end tax plan can be helpful.
There also might be a gap in "income" when you quit working. The paycheck stops, but maybe the new system is still getting set up, so the first few months come out of whatever is sitting in checking, and the account is lower than you expected by the time the first transfer runs.
I'd rather see more withholding than necessary in the first year. A refund is your own money coming back late. Being short in April is a check you weren't planning on, possibly with a penalty on top. This is one of the only times I'd ever feel comfortable "leaving the IRS a tip."
Closing thoughts
A few questions come up right after this one, and each of them needs its own post:
- What happens if the market drops early in your retirement, and what you sell when it does.
- Which account you pull from first, when the money could come from a taxable account, a traditional account, or a Roth.
- Whether to handle the tax through withholding or quarterly estimated payments, and how the timing works differently between the two.
- Whether to build the portfolio around dividends and interest, or fund the transfer out of total return instead.
So there's a lot that goes into planning out your retirement paycheck. My reminder to you is that you don't have to get it all 100% right, right away. Just take it one step at a time, and understand that you can make adjustments along the way if something isn't quite right.
