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.

Formula
Monthly Interest = (Annual Rate / 12) × Remaining Balance
- Model snowball or avalanche payoff strategies
- Track multiple debts and required minimum payments
- See the payoff order and target debt-free date
- Calculate total interest paid under the selected strategy
Watch out
Common mistakes
- The avalanche method generally saves more interest, while the snowball method provides psychological wins by clearing small remaining balances first.

FAQ
Frequently asked questions
How the calculation works and where its limits are.
What is the difference between Debt Snowball and Debt Avalanche?
Debt Snowball prioritizes paying off debts with the smallest balances first to create psychological momentum. Debt Avalanche prioritizes debts with the highest interest rates (APR) first to minimize total interest paid over time.
Which payoff strategy saves more money mathematically?
The Debt Avalanche strategy mathematically saves more total money in interest costs and pays off total debt faster when extra monthly payments are held constant.
How do extra monthly payments accelerate debt payoff?
Extra monthly payments reduce the principal balance directly, lowering subsequent monthly interest charges and compounding the speed of payoff with every eliminated balance.
Is this debt payoff calculator official financial or debt settlement advice?
No. All outputs are deterministic mathematical amortization schedules based on your entered balances and interest rates. Consult a certified non-profit credit counselor (NFCC) for formal debt management plans.
What should I do after calculating my debt payoff plan?
Review your overall debt-to-income ratio using our Debt-to-Income Calculator and establish a 3 to 6 month emergency fund once high-interest debts are cleared.
