Formula used

Monthly interest = Current balance × (APR ÷ 12).

Updated balance = Current balance + Monthly interest − Payment.

Extra payment = Monthly debt budget − Sum of minimum payments.

Avalanche method sends extra money to the highest APR debt first.

Snowball method sends extra money to the smallest balance first.

Custom method follows your manual priority ranking from lowest number upward.

Total interest is the sum of all monthly interest charges across the full schedule.

FAQs

1) What is a multi-debt payoff planner?

It is a planner that combines all debts into one monthly schedule. It estimates payoff dates, interest costs, and the order your extra money should follow.

2) What is the avalanche strategy?

Avalanche pays minimums on every debt, then sends leftover money to the highest APR balance. This usually produces the lowest total interest cost.

3) What is the snowball strategy?

Snowball pays minimums everywhere, then attacks the smallest balance first. It often creates quick wins, which can help motivation and consistency.

4) Why does the calculator need a monthly debt budget?

The budget represents the total amount you can pay across all debts each month. The planner uses it to split minimum payments and extra payoff money.

5) What happens if my budget is lower than minimum payments?

The planner stops and shows an error. Your monthly budget must at least cover the combined minimum payments to keep the schedule realistic.

6) Can I use manual priority instead?

Yes. Choose the custom option and assign lower numbers to debts you want paid first. The planner follows that ranking for extra payments.

7) Are taxes, fees, or changing rates included?

No. This version assumes fixed APR values and fixed minimum payments. Promotional rates, late fees, and variable-rate changes should be modeled separately.

8) Why download the plan as CSV or PDF?

CSV is useful for spreadsheet analysis and progress tracking. PDF works well for printing, client reviews, or saving a clean snapshot of the plan.
