About this tool
Become debt-free faster with our comprehensive debt payoff calculator. Whether you have credit card debt, student loans, personal loans, or medical bills, this calculator shows exactly when you'll be debt-free and how much interest you'll pay. Choose between the debt snowball method (paying smallest balances first for psychological wins) or debt avalanche method (paying highest interest rates first to save the most money).
The debt snowball method, popularized by financial experts, pays off your smallest debt first while making minimum payments on others. Once paid off, you "roll" that payment to the next smallest debt, creating momentum. The avalanche method targets highest interest rates first, mathematically saving more money but taking longer to see first payoff. Our calculator compares both strategies so you can choose what works for your situation.
See exactly how extra payments accelerate debt freedom. Just $50 or $100 extra per month can save thousands in interest and cut years off your payoff time. The calculator shows your debt-free date, total interest paid, and interest savings compared to minimum payments only. Perfect for creating a debt elimination plan, evaluating debt consolidation, and staying motivated with a clear payoff timeline.
Your financial information stays completely private - all calculations happen in your browser with no data sent to servers. Use the calculator to model different payment amounts and strategies. Works on all devices and can be used offline after the first visit.

FAQs
What is the debt snowball method?
The debt snowball method focuses on paying off your smallest debt balance first while making minimum payments on all other debts. Once the smallest is paid off, you take that payment amount and add it to the next smallest debt payment, creating a "snowball" effect. This method provides quick psychological wins and motivation, though you may pay slightly more interest than the avalanche method.
What is the debt avalanche method?
The debt avalanche method targets the debt with the highest interest rate first while making minimum payments on others. Once the highest rate is paid off, you tackle the next highest rate. This mathematically optimal approach saves the most money in interest but may take longer to pay off your first debt. Best for those motivated by saving money rather than quick wins.
Which method is better: snowball or avalanche?
Avalanche saves more money in interest (mathematically optimal), while snowball provides faster wins (psychologically motivating). If you need motivation and quick successes, choose snowball - it works because you stay committed. If you're disciplined and want maximum savings, choose avalanche. The best method is the one you'll stick with. Many people start with snowball for motivation then switch to avalanche.
How much extra should I pay toward debt each month?
Pay as much extra as you can afford while maintaining an emergency fund ($1,000 minimum). Even $50-100 extra makes a huge difference. For $15,000 at 18% APR with $300 minimum, adding just $100 extra saves $14,000 in interest and pays off 5 years faster. Review your budget to cut expenses - redirect dining out, subscriptions, or entertainment toward debt.
Should I consolidate my debt before using a payoff strategy?
Debt consolidation can help if you can get a lower interest rate than your current average. A personal loan at 10% to pay off credit cards at 18-24% saves significant interest. Balance transfer cards with 0% intro APR for 12-18 months are powerful if you pay off the balance before the rate jumps. Just avoid taking on new debt after consolidating - that defeats the purpose.
How long does it take to become debt-free?
It depends on your total debt, interest rates, and monthly payment. $20,000 at 18% with $500/month takes 56 months. Add $100 extra and it drops to 43 months. For fastest results: pay as much extra as possible, use avalanche method, avoid new debt, and consider side income to boost payments. Most people can be debt-free in 2-5 years with focused effort.
What should I do after paying off one debt?
Immediately apply that full payment amount to your next target debt (snowball) or highest interest debt (avalanche). Don't reduce your monthly debt payment total just because one is gone - that's how the momentum builds. For example, if you paid $200/month on a card that's now paid off, add that $200 to your next debt's payment. This creates exponential progress.
Can I still use credit cards while paying off debt?
Most experts recommend stopping credit card use while paying off debt to avoid adding to balances. Use debit or cash instead to stay within budget. Once debt-free, you can responsibly use cards for rewards if you pay the full balance monthly. If you must use credit for emergencies, factor those charges into your payoff calculator to maintain your timeline.
Should I pay off debt or save for emergencies first?
Financial experts recommend saving a small emergency fund ($500-1,000) first, then attacking debt aggressively. Without emergency savings, one car repair or medical bill forces you back into credit card debt. After debt-free, build a full 3-6 month emergency fund. The order: $1,000 emergency fund → pay off debt → full emergency fund → other goals.
How much interest will I pay on my debt?
Interest depends on balance, rate, and how fast you pay. $10,000 at 18% APR with minimum payments ($200/month) costs $7,454 in interest over 9 years. Double the payment to $400 and interest drops to $1,361 over 2.4 years - saving $6,093. High interest rates (18-24% on credit cards) are why debt feels impossible to escape. Extra payments dramatically cut interest.
