Full answer
Carrying high-interest debt, especially credit card debt at 20–29% APR, is one of the most financially damaging situations a household can be in — the interest compounds faster than most people can pay it down with minimum payments alone. A structured payoff strategy dramatically reduces total interest paid and time to freedom.
The debt avalanche method: list all debts by interest rate, highest to lowest. Pay minimums on all but the highest-rate debt, and put every extra dollar toward that one. Once it's paid off, redirect all those payments to the next highest-rate debt. This approach minimizes total interest paid and is mathematically optimal.
The debt snowball method, popularized by Dave Ramsey: list debts by balance, smallest to largest. Pay minimums everywhere, attack the smallest balance first. When it's gone, roll that payment into the next. The psychological benefit of clearing accounts quickly keeps many people more motivated — research by Harvard Business Review found people following the snowball method were more likely to complete their debt payoff than those using the avalanche.
Either strategy requires finding extra money to put toward debt. Common sources: canceling subscriptions, a temporary spending freeze on discretionary categories, selling items, picking up extra work, or refinancing high-interest debt to a lower rate via a personal loan or balance transfer card (many offer 0% for 12–21 months, which can be powerful if you can pay off within the promotional window).
This is general information — consult a financial advisor for personalized debt management advice. If you're overwhelmed by debt, a nonprofit credit counseling agency (NFCC member agencies) can provide free or low-cost guidance and may negotiate lower rates through a debt management plan.
