Mathematically, consumers are best off eliminating the debt on the card with the highest interest rate first. But researchers found that many of us tend to pay off the card with the smallest balance first, even if it carries the lowest interest rate. By not tackling the most expensive debt first, we end up paying more in the long run.
"There is an emotional benefit to closing out an account," says Scott Rick, assistant professor of marketing and co-author of the University of Michigan study.
Sure, it feels good to eliminate a card debt. And some financial advisers advise consumers to wipe out the smallest debt first. But these days, when so many of us struggle to pay bills, we have to be smart about how we use every dollar. And in this case, that means paying off the highest-rate credit card first.
Of course, paying off the smallest balance first isn't a mistake if that card has the highest rate.
"We show that people do it even when it is a mistake," Rick says.
He calls this tendency of ours "debt account aversion." In other words, if we have several debts, we fixate on reducing their number — not the total amount of indebtedness.
Rick noticed this idiosyncrasy when, as a doctoral student, he received a $600 government rebate. He had two credit cards with balances, and he used most of the money to pay off a low-rate card with a low balance, instead of the bigger debt with a higher rate. Only later did he think about why he made the wrong financial choice.
"There's a lot of research on how they use credit cards to accumulate" debt, Rick says. "We know very little on how people manage their debt."
Rick says consumers often aren't aware of their cards' interest rates or the compounding effect.
The CARD Act of 2009 required card issuers to show consumers on statements how long it would take to pay off the balance by making minimum payments. And the Consumer Financial Protection Bureau now is looking at ways to simplify card agreements so consumers better understand the terms.
But Rick says credit card statements should display the interest rate as prominently as the amount owed. Now, he says, the interest rate is buried on the second page.
"The rate should be in as big a font as the balance," he says.
Some financial advisers recommend paying off the smallest balance first, regardless of the interest rate. This gives consumers a sense of achievement, they say, and provides the momentum to tackle the card with the next-lowest balance, and so on, until all the debt is gone.
Rockville financial planner Christopher Brown says a sense of achievement is important, but there are ways to get it and reduce expensive debt.
He says consumers should focus on reducing the debt on the highest-rate card by a certain amount. If the card balance is $10,000, aim to get that down to $5,000. Once that target is reached, they can celebrate by giving themselves a small reward, he says.
Some advisers suggest going with any approach that motivates people to pay off plastic.
"People naturally want to spend," says Derrick Kinney, a financial adviser in Arlington, Texas. "They don't naturally want to pay off debt."
Kinney suggests consumers tally their card balances this new year and set a goal to pay off a set amount in the next 90 days.
"Whether you make payments on the smallest card or largest card, it really doesn't matter," he says. "The key is to set a goal for 90 days. Pay it off aggressively."
And like Brown, Kinney says consumers should give themselves a small reward for meeting that goal.
That can be taking a half-day off work as a mini-vacation or blocking out some personal time to read a book, Kinney says.
"Anything you wouldn't want to put on a credit card."
