The age-old question: Should you prioritize paying off debt or investing?
Or, if you’re ambitiously trying to do both: To what extent should you prioritize each?
The answer isn’t the same for everyone. It’s easy from the outside to say, “Don’t invest until you’re debt-free.” Or, “The market has higher returns than your loan interest, so why would you pay it off?”
However, it comes down to what you feel comfortable with. (I know — lame answer, right?)
But if you’re a numbers person — and because my editor won’t let me end this post right here — let’s dive into some specific figures to help you decide whether to prioritize paying off debt or investing.
Should You Pay Off Debt or Invest?
There are a lot of factors to consider: interest rates, amount of debt, income, expenses, etc.
But to put money toward either, you must have a surplus after your monthly expenses that you can put toward retirement or debt.
The quickest way to do that is to lower your expenses and/or increase your income. But even after that, people will have differing surpluses based on where they live, their life situations, etc.
Someone who has enough surplus to pay off $50,000 in two years should think about investing differently than someone who plans to take 10 years to pay it off.
So let’s look at the fictional examples of Adam and Sharon. Both are 25. Both have $50,000 of debt and are paying an average interest rate of 6.45%.
Adam has a sizable surplus. He plans pay off $50,000 in two years with the help of his wife’s income, side hustling and cutting back expenses.
But Sharon has very little surplus. So she plans to pay off her $50,000 in 10 years.
Why Adam Might Want to Invest While Paying Off Debt…
If Adam sticks with his plan to put his entire surplus toward paying off his debt rather than investing, he’ll make 24 payments of about $2,226 and pay just over $3,400 in interest.
But suppose Adam opts to use part of his surplus to max out his Roth IRA by investing $6,000 a year. He’ll end up making 32 payments of $1,726, rather than 24 payments of $2,226. He’ll pay an extra $1,000 in interest.
But he’ll have an extra two years of Roth IRA contributions — $12,000 — invested.
That $12,000 alone compounded over 35 years in a market seeing 6% return will turn into $92,000 by the time Adam is 62.
Even though he’ll pay an extra $1,000 in interest, because Adam is paying off his loans so fast, taking advantage of some investing while paying off his debt would net him an extra $90,000 in the long run.
… but Sharon Should Focus on Getting Rid of Debt
If Sharon pays back her $50,000 debt over 10 years, she’ll make 120 payments of about $570. She’ll pay a total of around $18,000 in interest.
If she starts maxing out her Roth when she becomes debt-free — in 10 years at age 35 — she’ll have contributed $30,000 by age 40. If she continues contributing $500 per month from age 36 to 60, assuming 6% growth, she’ll have $304,000 at age 60.
If Sharon decides she doesn’t want to wait to invest and puts $50 per month toward her Roth IRA, she’d end up making 137 payments of $520 and paying over $2,700 extra in interest on her debt. She’ll have contributed $6,850 in her Roth over that time. At 6% growth, the balance would be $8,357 by the time she’s debt-free.
That’s a growth of $1,507 in her Roth at the expense of an extra $2,700 in interest paid on debt.
If she then starts contributing $500 per month to her Roth at age 38 through age 60, she’d have $290,000 at that point — $14,000 less than if she’d focused on paying off her debt instead of investing during that time.
Of course, no financial situations will be the same as Adam and Sharon’s are.
The most valuable lesson from these scenarios is that you have to run the numbers for your own situation.
You might not stick with the strategy you begin with. If you’re not investing, you might spend a few months refining your budget and getting used to going out less. Maybe you’ll then find that you have extra money to invest or that you can pay off your debt much quicker than you anticipated.
Alternatively, you might invest for a while and then encounter something that cuts your income. So it might make sense to take a break from investing in the short term.
As a rule of thumb, if you can max out an IRA and still be debt-free in four years or less, it may be worth paying a little extra in interest to start investing.
If your budget is too tight, or your interest rates are hovering at or above the average rate of return we use to calculate retirement savings — 6%-8% — then don’t stress about your IRA.
But remember: As long as you’re doing wise things like saving, paying off debt and investing, you’re already on the right track.
