Debt payoff calculator

Compare snowball (smallest balance first) vs avalanche (highest APR first) with the same extra payment. Monthly interest is estimated as balance × APR ÷ 12. Not financial advice—lender methods differ.

Example:
Card A, 1200, 22.99, 35
Card B, 3400, 19.99, 75
Loan, 5000, 10.99, 150

Result

Run a comparison to see estimated months and interest.
