Debt Payoff Calculator
Enter all your debts — credit cards, personal loans, student loans, medical bills — add any extra monthly payment, and instantly compare the two most effective payoff strategies. The debt avalanche method minimizes total interest paid; the debt snowball method maximizes motivation with faster early wins. See your exact debt-free date and total interest cost for both approaches.

How to Use This Calculator
- 1 List each debt with its current balance, interest rate (APR), and minimum monthly payment.
- 2 Enter any extra amount you can pay beyond the minimums each month.
- 3 Choose Avalanche (highest-rate debt first — lowest total interest) or Snowball (smallest balance first — fastest psychological wins).
- 4 The calculator simulates month-by-month payoff and shows your debt-free date and total interest paid.
Debt-Free Faster: Tips
- ✓ Avalanche saves the most money; Snowball is better if you need motivation — both beat paying minimums only.
- ✓ Even $50–$100 extra per month dramatically cuts payoff time and total interest on high-rate credit card debt.
- ✓ Consolidating high-rate credit cards (18–25%) into a lower-rate personal loan (8–12%) can slash interest costs.
- ✓ Build a $1,000 emergency fund before aggressively paying debt — otherwise emergencies go right back on the credit card.
Frequently Asked Questions
What is the debt avalanche method?
Pay minimums on all debts, then direct every extra dollar to the highest-interest-rate debt first. Once paid off, roll that payment to the next-highest-rate debt. Mathematically optimal — minimizes total interest paid over time. Best for disciplined borrowers focused on saving the most money.
What is the debt snowball method?
Pay minimums on all debts, then direct extra payments to the smallest balance first. Each payoff eliminates a bill and builds momentum — the 'snowball' effect. Costs more in total interest than avalanche, but provides faster psychological wins that help people stay on track.
Should I pay off debt or invest?
If your debt's interest rate exceeds your expected investment return, pay off the debt first. Always capture employer 401k matching first (it's an instant 50–100% return). High-rate credit card debt (18–25%) should almost always be prioritized over investing in taxable accounts.
What is debt consolidation and when does it make sense?
Debt consolidation combines multiple debts into one loan at a lower interest rate — for example, moving 22% credit card debt to a 10% personal loan. It makes sense when you qualify for a meaningfully lower rate and commit to not accumulating new debt afterward.
