Formula used

Monthly interest rate
Monthly Rate = APR ÷ 12 ÷ 100
Updated balance after interest
New Balance = Current Balance + (Current Balance × Monthly Rate)
Monthly payment application
New Balance = Balance After Interest − Minimum Payment − Extra Allocated Payment
Total interest paid
Total Interest = Sum of monthly interest charges across all debts
Total repayment cost
Total Paid = Original Debt + Total Interest

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.

Frequently asked questions

1. What does this calculator estimate?

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.

2. What is the avalanche strategy?

Avalanche sends extra money to the highest APR first. This usually minimizes total interest and often gives the lowest total repayment cost over time.

3. What is the snowball strategy?

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.

4. Why must minimum payment exceed monthly interest?

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.

5. Does the calculator handle zero-interest debts?

Yes. Zero-interest balances are included normally. They receive minimum payments and extra payment only when selected by the chosen repayment strategy.

6. Are taxes, fees, or late charges included?

No. The model uses balance, APR, and payment assumptions only. Penalties, compounding differences, promotional changes, and lender fees are not included unless added manually.

7. Can I use this for loans and credit cards together?

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.

8. How accurate are the results?

Results are good planning estimates. Actual lender calculations may differ because of statement cycles, variable APRs, changing minimum formulas, and irregular payment dates.
