Prioritize High Interest
Debts are ranked by APR. Your additional monthly payment is directed toward the account charging the highest interest rate.

Repayment strategy
What Is the Debt Avalanche Method?
The debt avalanche method focuses extra payments on the debt with the highest annual percentage rate while maintaining minimum payments on your other accounts.
Keep Paying Minimums
Continue making the required minimum payment on every debt to help avoid missed payments, fees, and account problems.
Roll Payments Forward
Once one debt is cleared, its previous payment amount becomes available for the next highest-interest balance.
Example Avalanche Priority
-
1
Credit Card – 24.99% APR Highest interest debt receives extra payments
-
2
Personal Loan – 14.50% APR Targeted after the credit card is paid
-
3
Auto Loan – 7.25% APR Lower-interest debt remains last

Frequently asked questions
Debt Avalanche Calculator FAQs
Understand how the strategy works and what your estimated results mean.
What does a debt avalanche calculator do?
It organizes debts from the highest APR to the lowest APR, applies minimum payments, directs extra money toward the most expensive debt, and estimates the payoff time and interest cost.
Is the debt avalanche method the fastest strategy?
When payments and balances are equal, targeting the highest APR generally minimizes total interest. The exact payoff time depends on your balances, rates, fees, and monthly payment amount.
What happens if my budget is below the minimum payments?
The calculator will display a warning because an avalanche plan requires enough money to cover all required minimum payments. Contact your lenders early if you cannot meet those obligations.
Should I include debts with a zero percent APR?
Yes. Include them so your complete monthly payment obligation is considered. However, review when the promotional rate expires, because the future APR could change your repayment priority.
What is the difference between avalanche and snowball?
The avalanche method targets the highest interest rate first. The debt snowball method targets the smallest balance first, regardless of its interest rate.
Does the calculator include lender fees?
No. The estimate is based on balances, APRs, minimum payments, and your monthly budget. Late fees, annual fees, variable rates, and lender-specific interest calculations are not automatically included.
