How to create a debt payoff plan

1 Add each of your debts with a name, current balance, annual percentage rate (APR), and minimum monthly payment.
2 Click the + Add Another Debt button to include additional debts. You can add as many as needed.
3 Choose your payoff strategy: Avalanche (highest APR first to minimize interest) or Snowball (smallest balance first for quick wins).
4 Enter any extra monthly payment you can make above the total minimums. Even $50 to $100 extra can dramatically shorten your payoff timeline.
5 Click Calculate Payoff to see your total debt-free timeline, total interest paid, and the order in which each debt will be paid off.

The avalanche method prioritizes debts with the highest interest rates first, which mathematically minimizes the total interest you pay over the life of your debts. After making minimum payments on all debts, any extra money goes toward the highest-APR debt until it is paid off. Then that freed-up payment rolls to the next highest-APR debt, creating a cascade effect that accelerates payoff.

The snowball method, popularized by financial advisors, prioritizes the smallest balance first regardless of interest rate. While you may pay slightly more in total interest compared to the avalanche method, the psychological benefit of eliminating individual debts quickly can provide motivation to stick with your payoff plan. Research shows that people using the snowball method are more likely to stay committed to their debt elimination goals.

Extra payments make a dramatic difference. On a $20,000 credit card balance at 20% APR with a $400 minimum payment, adding just $200 extra per month can cut your payoff time from over 9 years to under 3 years and save thousands in interest. The calculator shows exactly how extra payments affect your timeline, making it easy to decide how much extra you can commit each month.
