Dear Liz: My wife and I aggressively paid down our mortgage and now have it paid off, but we don’t have much saved for retirement. I make about $90,000 a year and will receive a teacher’s pension that will replace between 30% and 60% of that (depending on what option we choose) when I retire in about 10 years. It probably won’t be enough to live on. We will receive no Social Security benefits. We have no other debts, and we would like to make up for lost time as best we can on retirement preparation. What is your best advice for people like us who have diligently paid off their mortgage but have not diligently put money away for retirement?

Answer: The older you get, the harder it is to make up for lost time with retirement savings. You probably can’t do it if retirement is just a few years away.

This is not to make you feel bad, but to serve as a warning for others tempted to prioritize paying off a mortgage over saving for retirement.

If you’re in your 50s, you’d typically need to save nearly half your income to equal what you could have accumulated had you put aside just 10% of your pay starting in your 20s. The miracle of compounding means even small contributions have decades to grow into considerable sums. Without the benefit of time, your contributions can’t grow as much so you have to put aside more.

But you can certainly save aggressively and consider a few alternatives for your later years.

Once you hit 50, you can benefit from the ability to make “catch up” contributions. For example, if you have a workplace retirement plan such as a 403(b), you can contribute as much as $26,000 — the $19,500 regular limit plus a $6,500 additional contribution for those 50 and older.

You and your spouse also can contribute as much as $7,000 each to an IRA; whether those contributions are deductible depends on your income and whether you’re covered by a workplace plan. If you’re covered, your ability to deduct your contribution phases out with a modified adjusted gross income of $105,000 to $125,000 for married couples filing jointly. If your spouse isn’t covered by a workplace plan but you are, her ability to deduct her contribution phases out with a modified adjusted gross income of $198,000 to $208,000. (All figures are for 2021.)

If you can’t deduct the contribution, consider putting the money into a Roth IRA instead because withdrawals from a Roth are tax free in retirement. The ability to contribute to a Roth IRA phases out with modified adjusted gross incomes between $198,000 and $208,000 for married couples filing jointly.

If possible, a part-time job in retirement could be extremely helpful in making ends meet. So could downsizing or tapping your home equity with a reverse mortgage. A fee-only financial planner could help you sort through your options, as well as help you figure out the best way to take your pension when the time comes.
