The calculator simulates repayment month by month. Minimum payments apply first. Any extra payment is then assigned using either avalanche or snowball logic until every debt reaches zero.
It estimates payoff time, total interest, total amount paid, monthly balance decline, and debt-by-debt payoff timing based on your balances, APRs, minimums, and extra payment amount.
Avalanche sends extra money to the highest APR first. This usually minimizes total interest and often gives the lowest total repayment cost over time.
Snowball sends extra money to the smallest balance first. It can create faster psychological wins because individual accounts close earlier, even if interest costs stay slightly higher.
If minimum payment does not exceed monthly interest, the balance may never shrink. The calculator flags that condition because payoff would be unrealistic or impossible.
Yes. Zero-interest balances are included normally. They receive minimum payments and extra payment only when selected by the chosen repayment strategy.
No. The model uses balance, APR, and payment assumptions only. Penalties, compounding differences, promotional changes, and lender fees are not included unless added manually.
Yes. You can mix installment loans, store cards, medical balances, and revolving credit accounts, as long as each entry has a current balance and payment details.
Results are good planning estimates. Actual lender calculations may differ because of statement cycles, variable APRs, changing minimum formulas, and irregular payment dates.
