Should You Pay Off Your Debt Before Investing?

By Larry Swedroe, on April 1, 2009

In this Ask the Expert with Larry Swedroe article, Lynnae from Being Frugal wants to know if people that are in debt should be thinking about investing, or is it best to focus on getting out of debt first. Here’s the question from Lynnae:

Is it best to get out of debt before you start investing?

Answer From Larry Swedroe

The issue is actually fairly complex, though some parts of the question are easy to answer.

You should pay off your debt before investing

First, if you have any credit card debt you should not be investing. Pay that off first as the cost almost certainly exceeds any reasonable expectation of return on prudent investments. So pay off all of your credit card debt every month before you invest.

Second, if you have any fixed income investments (e.g., bonds, CDs), you should likely sell them and pay off your debt as the return on those investments is likely to be less than the cost of the debt (unless you have a subsidized student loan).

And I would also pay off any debt before investing in stocks and the reason is that you will not be receiving the full risk premium for taking the risk of owning equities. So you are taking stock risk but not getting stock returns (net of the cost of the debt).

Let me explain…

Understanding risk premium and why you should pay off debt before investing

The cost of the debt you have is almost certainly higher than the risk-free rate of return (the return on one-month Treasury bills). Other investments like stocks have higher expected (but not guaranteed) returns. The higher expected return is called a risk premium. And it is called a risk premium for a reason; you are taking risk. How large a premium is a reflection of the degree of risk.

• So longer term Treasury bonds have provided a risk premium of about 2% a year above the return on one-month T-bills. That is a premium for taking what is called term risk (related mostly to inflation).
• Stocks have earned about 7% a year above the return on T-bills.
• And riskier small and value stocks have earned further risk premiums.

Thus, the market has historically priced stocks to provide that size and value risk premium.

Let’s take an example. Say treasury bills are at 4% and we expect stocks to return 10%. That is a risk premium of 6%. But if your debt costs you 8% then your risk premium is only 2%. You are taking risk that the market prices at 6% and earning just 2%. That does not make sense to me.

Now it is a bit more complex since you should look at after tax returns. So you should adjust the cost of the debt to reflect the true after tax cost (assuming the interest is tax deductible) and adjust the equity return to reflect the lower capital gains rates (assuming it is in taxable account).

Mortgage is a debt just like any other

Another important issue relates to mortgage debt. Many people make the mistake of not thinking of the mortgage on their home as debt when it comes to their asset allocation. Mortgage debt should be treated the same way as any other debt in terms of analyzing the costs versus the expected return on any investment.

Paying down your mortgage versus investing

And finally, there is the issue of the need to take risk. If your financial plan requires you to earn a high rate of return then you may need to carry a home mortgage and take the risk of investing in stocks (instead of paying down the mortgage). But you then should be sure you also have the ability and willingness to take that risk as well. My book, The Only Guide to a Winning Investment Strategy You’ll Ever Need, has a chapter on how to build a portfolio, specifically addressing the issues of ability, willingness and need to take risk. I provide specific tables that are easy to use to help you figure out the right asset allocation for you.

I would add one last point. While stocks have historically earned about 10% a year, providing that large risk premium, most financial economists believe that going forward the return to stocks will be somewhat lower, more in the range of 7-8 percent per annum.

Best wishes,

Larry
