Getting Out of Debt
Paying off debt is one of the most impactful financial moves you can make. High-interest debt, particularly credit card debt, can cost thousands of dollars in interest over time if you only make minimum payments. The key to accelerating debt payoff is directing as much money as possible toward the principal balance, which reduces the amount of interest that accrues each month.
Avalanche vs. Snowball
Two popular debt repayment strategies are the avalanche and snowball methods. The avalanche method targets the highest interest rate first, minimizing total interest paid. The snowball method targets the smallest balance first, providing quick psychological wins. Both methods are effective — the best one is the one you will stick with. Many financial experts recommend the avalanche for math optimization and the snowball for behavioral motivation.
The Minimum Payment Trap
Credit card minimum payments are typically 1-3% of your balance or a fixed dollar amount, whichever is greater. At these levels, it can take decades to pay off a moderate balance while paying more in interest than the original amount borrowed. Even small additional payments make a dramatic difference. Use this calculator to see exactly how much time and money you can save by paying more than the minimum each month.
Frequently Asked Questions
What is the debt avalanche method?
The debt avalanche method prioritizes paying off debts with the highest interest rate first while making minimum payments on all other debts. This approach minimizes the total interest you pay over time. Once the highest-rate debt is paid off, you redirect that payment to the next highest rate, creating an accelerating payoff effect.
What is the debt snowball method?
The debt snowball method prioritizes paying off the smallest balance first, regardless of interest rate. While mathematically less efficient than the avalanche method, the snowball method provides psychological wins that can help maintain motivation. Once a small debt is eliminated, its payment is added to the next smallest balance.
Why are extra payments so powerful?
Extra payments go directly toward reducing your principal balance, which means less interest accrues in future months. Even an extra $50-100 per month can save thousands in interest and shave years off your payoff timeline. The higher your interest rate, the more impactful extra payments become. On a $25,000 debt at 18% APR, an extra $200/month can save over $10,000 in interest.
Why do minimum payments take so long to pay off debt?
Minimum payments are designed to keep your account in good standing, not to pay off debt quickly. On high-interest debt, a large portion of each minimum payment goes toward interest rather than principal. For example, on a $10,000 credit card balance at 20% APR with a $200 minimum payment, about $167 goes to interest in the first month — only $33 reduces your balance.
What is a good debt-to-income ratio?
A debt-to-income (DTI) ratio below 36% is generally considered healthy, with no more than 28% going toward housing. DTI between 36-49% means you should be working to reduce debt. Above 50% indicates serious financial stress. Calculate your DTI by dividing your total monthly debt payments by your gross monthly income.
