Guidelines for accelerated loan payoffs

If you've been frustrated with the faltering markets lately, as have most Americans, you've probably been discouraged from investing your disposable income into the stock market. That could very well be the correct choice for you and your family, depending on your financial plans and tolerance for risk. But if you're not investing in the stock market, what are you doing with all that money? Are you putting it in a savings account? Or a CD? Or are you paying down debt?

My personal financial plan calls on paying down my debt during the economic downturn. The markets have been unpredictable (and by unpredictable, I mean they're going straight down) and the amount of debt that my wife and I have will take a relatively short amount of time to pay off. We're hoping that when we're out of debt in a couple of years (excepting our mortgage), the market will be trending upward and we'll have a larger portion of our income to regularly invest, given the fact that we'll have no regular payments for our auto or student loans.

If you're going to start paying down debt in lieu of investing, consider the following three guidelines to help you prioritize where your money is being sent:

1. Pay off the loans with the highest interest rate first (as long as they're not tax advantaged)
Dave Ramsey will tell you to pay off your loan with the smallest amount first instead of the one with the highest interest rate. This adds a layer of subjectivity to your personal finance that, while making you "feel good" about paying down your debt, will cost you money. In a recent post, I discuss the financial disadvantages his plan.

Non-tax-advantaged loans that fall into this category include credit card debt, personal loans, and auto loans. Look for your highest interest rate, and start sending whatever extra money that you can to pay it off.

2. Pay off loans incrementally -- don't save your money and pay it off in one fell swoop
I'll give a personal example here. Though I still have a couple of years' worth of payments remaining on my auto loan, I'm hoping to have it paid off by January. While maintaining my "emergency fund" in my checking account, and have been placing my monthly disposable income into an "auto loan payoff fund" that lives in a savings account. Last I checked, I had a few thousand dollars in there.

I had originally planned to keep making my regular monthly payments and continue saving money in the payoff account until I had enough money to pay off the car. But then I crunched a few numbers and found the flaw in my plan. Here's how it goes:

Whenever you make a regular monthly payment on a loan, a portion of that payment goes toward the principal balance and another portion goes toward interest. Those percentages are determined by a couple of different factors:
1) the time left on the loan (the less time left, the higher the percent that goes toward principal) and
2) the amount of remaining principal balance (the lower the balance, the higher the percent that goes toward principal).

So if my monthly payment is $500, maybe $400 of that goes toward principal and the other $100 goes toward interest. Next month, after the principal balance has been slightly reduced, the payment distribution may be $405/95, and so on. But if I have a few thousand dollars in a savings account that's just waiting to be used to pay off the loan, I am better off sending that money as a principal-only payment immediately. If I reduce my principal by, let's say, $5,000, a much higher percentage of my regular monthly payment will go toward principal. If you're paying off a loan on an accelerated schedule, sending the extra money as soon as you have it instead of saving it and sending one big fat check at the end may save you several hundred dollars over the life of the loan.

3) After non-tax-advantaged loans are repaid, evaluate the tax benefits of other loans before repaying them.
Once your credit cards, personal loans, and auto loans are paid off, hopefully all you'll have left is a mortgage and maybe a student loan. At this time, before deciding to accelerate the payoff on these loans, you should reevaluate the stock market. Has it picked up yet? If you're still not feeling warm and fuzzy, do some math and figure out how much your tax-advantaged debt is really costing you.

If your mortgage has a 5% interest rate, remember that depending on your tax bracket, you'll get maybe 25 or 28 percent of that interest back in your tax refund. So think of the effective cost of the debt to be 3.75% (5%, minus 25% of the 5). Your mortgage is a very long-term loan, and you won't see the benefits of paying it down early for a very long time. Paying it off early won't reduce your monthly payments. Sure, it will be paid off sooner, but even if you double your monthly mortgage payment every month until it is paid off, it will take almost 10 years to pay off a 30-year mortgage. If the effective interest rate on your mortgage (the interest rate less the tax benefit) is only slightly higher than the amount you could earn in a CD or a savings account, I would rather see you hold onto that money just in case you need it.

With all loans, especially those that are tax-advantaged, the lower the interest rate, the less sense it makes to accelerate your payoff. My friend Quang's student loan has a 3% interest rate. I wouldn't pay that off early for the world. But the rate on one of my wife's student loans is 7.9%. I can promise you that as soon as my car is paid off, the next thing to go will be that sucker.

Non-tax advantaged debt is nobody's friend. If you're not satisfied with the performance of your investment portfolio, it could be a wise decision to pay it off early in lieu of investing. But if your only debts are mortgages or student loans, think twice before you start sending extra cash toward the principal. True, you're saving yourself money in the long run, but remember that you're also reducing your tax writeoff and parting with that money for a long, long time. And keep in mind: even if you're using the standard deduction (not itemizing), your student loan interest is still tax deductible!
