Debt Snowball vs Avalanche Calculator

AI summaries describe the two strategies — but they can't tell you the exact months and dollars for your own stack of cards and loans. Enter your debts and extra payment to see which method gets you debt-free sooner.

The debt & budget cluster

Educational estimate, not financial advice. Both strategies apply your minimum payments to every debt each month and direct the extra payment to the priority debt (smallest balance for snowball, highest APR for avalanche), cascading to the next when one is cleared. Interest accrues monthly at APR ÷ 12. If any minimum is below that debt’s monthly interest, the balance grows and the tool flags it. Results are illustrative; confirm payoff specifics with your lenders.
