Free Debt Avalanche Spreadsheet Calculator
The Debt Avalanche method is the mathematically optimal debt repayment strategy. By ordering your debts from highest interest rate to lowest interest rate, you eliminate the most expensive loans first. This minimizes the compounding interest charges that keep borrowers trapped in high-interest consumer debt, resulting in thousands of dollars in interest savings and a faster debt-free date.

Frequently Asked Questions
How much money does the debt avalanche save compared to the snowball?
Depending on the spread between your highest interest rate (such as a 26% APR credit card) and lowest rate (such as a 5% student loan), the avalanche can save hundreds to thousands of dollars in lifetime interest charges.
Is my credit score affected by choosing avalanche over snowball?
Both strategies improve your credit score over time by lowering your credit utilization ratio. The avalanche also reduces the total amount of interest capitalizing into your balances.
