Q. Why do some physicians seem to be so much more financially adept than others? What are the keys to success?

A. There is an old adage that states, “Personal finance is both personal and finance.” That is to say, there are two components to success: behavior and math. Most experts agree that 80 percent of success in personal finance is due to optimizing your behavior and only 20 percent is due to learning the rules of the game.
When trying to eliminate or reduce debt, the mathematically correct thing to do is to pay the minimum on all the debts in order to avoid additional fees and penalties, then use any extra income to pay down the debt with the highest interest rate. Despite that fact, financial coaches have advocated a different approach for years, putting the additional income toward the smallest debt regardless of interest rate. What these “soldiers in the trenches” have learned, which was recently confirmed by a Harvard study, is that people are more likely to get out of debt faster when they feel they are making progress. Behaviorally, it feels like you are making more progress when you have fewer debts and are writing fewer checks each month, even if the total debt is slightly larger. This is often called a “debt snowball” because as the number of debts decrease, borrowers feel they are gaining momentum and are more likely to complete the task simply because they stick with the task longer and put more money toward the debt rather than spending it.
Many physicians appropriately struggle with the decision of whether to direct additional income toward investments or debt reduction. This becomes particularly problematic when the debt is at a very low interest rate, such as some student loans and many mortgages. It seems mathematically obvious that, even with some additional risk, the investor is likely to outperform the guaranteed 1–3 percent return from paying off low-interest-rate debt. However, what often happens is money that would have gone toward the debt is spent rather than invested. After a while, you’re “borrowing at 2 percent” to pay for your Caribbean vacation, that ski trip, and the Tesla in the driveway. This “I can make the payments” mentality actually slows the accumulation of wealth despite being, theoretically, mathematically superior. The best way to combat this natural behavioral tendency is to have a written plan for debt elimination, such as paying off student loans within three years or your mortgage within 10 years. Paying off even low-interest-rate debt early is a good idea, but you don’t want to be foolish about it. For example, it would be silly to send extra money to the mortgage lender when you are not contributing enough to your 401(k) to get the entire employer match.
