Interpretation
How Debt Payoff Planning works
The Debt Payoff Calculator models a snowball plan (smallest remaining balance first) or avalanche plan (highest interest first). Enter each balance, interest rate, and required minimum payment, then enter the total amount you can pay monthly. It applies every minimum payment first and sends the remaining amount to the selected priority debt.
