Common Myths About Paying Off Debt (And What the Evidence Actually Shows)

This myth likely stems from a misunderstanding of how credit utilization works. Your score benefits from using credit — not from paying interest on it. Credit scoring models reward low utilization (generally below 30% of your available limit) and on-time payments. Carrying a balance month to month means you're paying interest for no credit-building benefit. Paying in full, on time, achieves the same utilization signal without the added cost.

The urgency of repaying any debt is largely a function of its interest rate relative to what you could otherwise do with that money. High-interest consumer debt — particularly credit cards, which often carry rates well above 20% APR — erodes wealth quickly and generally warrants prioritization. Lower-rate debts, such as certain mortgages or subsidized student loans, may not need to be paid off aggressively at the expense of building savings or an emergency fund. Treating all debt as equally harmful can lead to poor trade-offs, like paying down a 4% mortgage while carrying no emergency reserve and no retirement contributions.

The logic of "eliminate debt first" is understandable — every dollar toward savings seems to cost you in interest. But this ignores a critical practical risk: without any savings buffer, a car repair or medical bill often forces people back onto credit cards, undoing progress. Financial educators widely recommend maintaining a small liquid emergency reserve — even while aggressively paying down debt — to prevent this cycle. The optimal balance depends on your interest rates, income stability, and existing obligations.

Credit scoring models consider the ratio of your balances to your total available credit (utilization) and the average age of your accounts. Closing an old card reduces your available credit limit, which can push your utilization ratio higher even if your balances haven't changed. It may also shorten your average account age. Unless a card carries an annual fee you can't justify, keeping an old account open — even if unused — is often less disruptive to your score than closing it.

Consolidating multiple debts into a single loan or balance transfer can lower your interest rate and streamline payments — but the outcome depends heavily on the terms, fees, and your repayment behavior afterward. Extending the repayment term to lower monthly payments, for example, often results in paying more interest overall, not less. Some consolidation products also carry origination fees or introductory rates that reset higher later.

Credit card minimum payments are typically calculated as a small percentage of the outstanding balance or a low flat dollar amount. Because such a large portion of each payment goes toward interest rather than principal, the balance decreases very slowly. On a substantial credit card balance at a high APR, paying only the minimum can mean years — sometimes a decade or more — of repayment and significantly more paid in interest than the original borrowed amount. Increasing your monthly payment even modestly above the minimum accelerates payoff considerably.
