How this calculator works
Formula used
Minimum payments are made on all debts, while extra money goes to the highest APR remaining debt. Freed payments roll into the next target.
Example calculation
If a credit card has 24% APR and a personal loan has 10% APR, the avalanche method targets the credit card first.
