Many people do not effectively manage their debt but juggle multiple debts with different terms and interest rates.
The most effective way to pay off debt is to focus on the loans with the highest interest rates first. However, research shows that consumers who manage multiple debts prefer to reduce the total number of debts rather than reducing the total of their associated costs, even if they will pay more in the long run.

How we intuitively manage debt

<ul>
<li>The Prospect Theory suggests individuals are more sensitive to a loss than a gain of an equal amount. The urge to get in the black is so strong that people are motivated to pay off small debs without considering their interest rates.</li>
<li>The Goal-Gradient Theory supposes that consumers are more willing to make an effort towards small debt just to finish paying them off.</li>
<li>People do not take into account how interest compounds over time.</li>
</ul>

Psychological processes behind debt account aversion

<ul>
<li>We can set up automatic payments to the debt with the highest interest without regarding how much is owed on it.</li>
<li>We can consolidate multiple debts into a single loan. If you have five different loans with different interest rates, your loan servicer can consolidate each debt into one payment.</li>

A financially optimal player would allocate all of the money to the debt with the highest interest rate. Yet, even though participants experienced how interest compounded their debt from one round to the next, only 3% (5 of 162) allocated money in ways that were close to optimal. Instead, an overwhelming majority of participants elected to pay off the smaller debts first.The sheer number of people using this strategy (including MBA students who took finance classes) suggest that paying off the smaller debts first is not just a mistake, but a planned strategy rooted in our psychology. The research shows that individuals are “debt account adverse,” which means that consumers with multiple debts are motivated to reduce the total number of debts rather than reducing the total of their associated costs.There are multiple psychological processes that underlie debt account aversion. The first of which is prospect theory, which suggests individuals are much more sensitive to a loss than they are to a gain of an equal amount. For example, if you make a bet with someone and lose, you are more willing to enter a second bet at double-or-nothing than if you had won the first bet. What these kinds of results show is that the urge to get back to being in the black is so strong that people are more motivated to pay off small debts and close out accounts without considering how their interest rates differ.In addition to being disproportionately averse to losses, individuals are also largely motivated by a salient goal. This phenomenon is called <a href="http://journals.ama.org/doi/abs/10.1509/jmkr.43.1.39" dir="ltr">Goal-Gradient Theory</a>. For example, when customers are given a loyalty punch-card offering a free coffee after a certain number of purchases, they feel more motivated to buy more coffee as they get closer to the free one.&nbsp; Goal-Gradient Theory suggests that consumers are likely to be much more willing to put out effort (or allocate their scarce resources) towards debts that are smaller just to finish paying them off, even if the interest rate – and thus the total long-term cost – is less than other, larger debts.There is also a growing body of evidence suggesting that people do not effectively take into account the way interest compounds and grows over time. For example, when making the decision about how much to invest in their retirement, <a href="http://www.nber.org/papers/w21482" dir="ltr">research demonstrates</a> that people discount how much their contributions are worth in the future. In terms of debt, this means that people who choose to utilize their credit cards and to carry a balance are doing so without a full understanding of total cost of that debt in the future.<figcaption>Advertisement</figcaption>If we can’t trust our intuitions, how can we reduce our debt?There are a number of strategies and interventions that potentially could help minimize the cost of our natural tendency to behave in ways that cost us more in the long run. For example, setting up automatic payments to the debt with the highest interest, regardless of how much you owe on it, eliminates the monthly tension between rationality and intuition. Another strategy would be to structure the environment to ensure consumers allocate money optimally. For example, imagine if a consumer could just tell their bank or credit union (or an application) how much total money they can put toward debt that month and the bank or credit union would, in turn, optimally allocate the money across the multiple debts according to interest rates and possible tax benefits.However, often one of the most straightforward ways to minimize the cost of debt-account aversion is to consolidate multiple debts into a single loan. For example, if you have five different student loans with varying interest rates, your loan servicer can consolidate each debt into a single payment. Yet, even though refinancing or consolidating debt can save money, many consumers do not choose to do so. Refinancing or consolidating debt requires time and effort to navigate a complex financial system. Refinancing in particular is a complex decision – we must choose which lender we should refinance with, what interest rate should we aim for, how many lenders we should ask before we have too many inquiries on our credit report. Research shows that complex decisions such as this lead to decision paralysis. That means we become unable to make a decision for fear of making the wrong one.
