Dear Penny: How Do I Save for Retirement With 3 Kids on a Teacher’s Salary?

Dear B.,

You still have 20 years to build your nest egg if all goes as planned. Sure, you’ve missed out on the extra years of compounding you’d have gotten had you accumulated substantial savings in your 20s and 30s. But that’s not uncommon. I’ve gotten plenty of letters from people in their 50s or 60s with nothing saved who are asking how they can retire next year.

I like that you’re already planning to work longer to make up for a late start. But here’s my nagging concern: What if you can’t work into your 70s?

The unfortunate reality is that a lot of workers are forced to retire early for a host of reasons. They lose their jobs, or they have to stop for health reasons or to care for a family member. So it’s essential to have a Plan B should you need to leave the workforce earlier than you’d hoped.

Retirement planning naturally comes with a ton of uncertainty. But since I don’t know what you earn, whether you have debt or how much you have saved, I’m going to have to respond to your question about how much to save with the vague and unsatisfying answer of: “As much as you can.”

Perhaps I can be more helpful if we work backward here. Instead of talking about how much you need to save, let’s talk about how much you need to retire. You can set savings goals from there.

The standard advice is that you need to replace about 70% to 80% of your pre-retirement income. Of course, if you can retire without a mortgage or any other debt, you could err on the lower side — perhaps even less.

For the average worker, Social Security benefits will replace about 40% of income. If you’re able to work for another two decades and get your maximum benefit at age 70, you can probably count on your benefit replacing substantially more. Your benefit will be up to 76% higher if you can delay until you’re 70 instead of claiming as early as possible at 62. That can make an enormous difference when you’re lacking in savings.

But since a Plan B is essential here, let’s only assume that your Social Security benefits will provide 40%. So you need at least enough savings to cover 30%.

If you have a retirement plan through your job with an employer match, getting that full contribution is your No. 1 goal. Once you’ve done that, try to max out your Roth IRA contribution. Since you’re over 50, you can contribute $7,000 in 2021, but for people younger than 50, the limit is $6,000.

If you maxed out your contributions under the current limits by investing $583 a month and earn 7% returns, you’d have $185,000 after 15 years. Do that for 20 years and you’d have a little more than $300,000. The benefit to saving in a Roth IRA is that the money will be tax-free when you retire.

The traditional rule of thumb is that you want to limit your retirement withdrawals to 4% each year to avoid outliving your savings. But that rule assumes you’ll be retired for 30 years. Of course, the longer you work and avoid tapping into your savings, the more you can withdraw later on.

Choosing what to invest in doesn’t need to be complicated. If you open an IRA through a major brokerage, they can use algorithms to automatically invest your money based on your age and when you want to retire.

By now you’re probably asking: How am I supposed to do all that as a single mom with a teacher’s salary? It pains me to say this, but yours may be a situation where even the most extreme budgeting isn’t enough to make your paycheck stretch as far as it needs to go. You may need to look at ways to earn additional income. Could you use the summertime or at least one weekend day each week to make extra money? Some teachers earn extra money by doing online tutoring or teaching English as a second language virtually, for example.

I hate even suggesting that. Anyone who teaches middle school truly deserves their time off. But unfortunately, I can’t change the fact that we underpay teachers. I want a solution for you that doesn’t involve working forever. That may mean you have to work more now.
