How to Use This Calculator
Add your debts
Enter each debt you're currently carrying — credit cards, car loans, student loans, personal loans, medical debt, or anything else with a balance and interest rate. For each one, you'll need the current balance, the APR (annual percentage rate), and the minimum monthly payment. You can find all of this on your most recent statement or by logging into your account online.
Choose your payoff method
The avalanche method targets the debt with the highest interest rate first, which saves you the most money mathematically. The snowball method targets the smallest balance first, which gives you faster wins and can help with motivation. Both methods work — research from Harvard Business Review found that people using the snowball method were more likely to stick with their plan and eliminate all their debt, even though the avalanche method is technically cheaper.
Set your extra monthly payment
This is the additional amount you can put toward debt each month beyond your minimum payments. Even an extra $50 or $100 per month can shave months or years off your payoff timeline. The calculator applies this extra payment to your target debt (highest rate or lowest balance, depending on your chosen method) after all minimum payments are made.
Understanding Your Results
Debt-free date
This tells you exactly when you'll be completely debt-free if you follow the plan. Try adjusting the extra payment slider to see how much faster you can get there. You might be surprised — adding just $100 extra per month to a $20,000 debt load can cut years off the timeline.
Total interest paid
This is the total amount of interest you'll pay across all your debts from today until they're fully paid off. Compare this number between the avalanche and snowball methods to see the difference. On large debt loads with high-interest credit cards, the avalanche method can save hundreds or even thousands of dollars in interest.
Total amount paid
This is everything you'll pay — principal plus interest — to eliminate all your debts. The difference between this number and your total current balances is the cost of carrying debt. It's a useful number to keep in mind when deciding whether to take on new debt in the future.
