| Date | Payment | Principal | Interest | Balance |

The debt snowball focuses on paying off your smallest debt balances first, regardless of interest rates. While you pay the minimum on all debts, any extra money goes toward the debt with the lowest balance.
Best for: People who need motivation and psychological wins to stay on track. Seeing debts disappear quickly can provide the momentum needed to stick with your plan.
The debt avalanche prioritizes debts with the highest interest rates first. You pay minimums on all debts, but extra payments target the highest APR debt, saving you the most money over time.
Best for: People focused on mathematical optimization who want to minimize total interest paid and can stay motivated without frequent "wins."
Even small extra payments can dramatically reduce your payoff time and total interest. An extra $50-100 per month often cuts years off your debt journey and saves thousands in interest charges.
Only have one card to pay off? The credit card payoff calculator shows your payoff date, total interest, and the payment needed to hit a goal date.
If your minimum payment is less than the monthly interest charge, your balance will actually grow each month. This is called negative amortization, and it's a sign you need to either increase payments or consider debt consolidation options.
Our calculator warns you if any debt has this problem. If a lower rate would help, check whether a loan actually saves money with the debt consolidation calculator.
The Snowball method pays off the smallest balance first for psychological motivation, while the Avalanche method pays off the highest interest rate first to save the most money. Both require paying minimums on all debts while focusing extra payments on one debt at a time.
Simply enter your desired debt-free date in the "Target Debt-Free Date" field, and our calculator will automatically determine the exact monthly payment needed. You'll see a breakdown showing what to pay on each debt to reach your goal. This is perfect if you have a specific date in mind, like before a wedding, home purchase, or retirement.
Extra payments directly reduce your principal balance, which means less interest accumulates each month. Even small extra payments can cut months or years off your payoff timeline and save significant money in interest charges.
This happens when your minimum payment is less than the monthly interest charge. Your balance will actually increase each month until you pay more than the interest. Our calculator will warn you about this situation and suggest the minimum payment needed to make progress.
Yes! You can export your complete amortization schedule as a CSV file for use in spreadsheets, or as a PDF for printing or sharing. You can also generate a shareable URL to bookmark or share your debt payoff plan.

Our calculations use the same formulas as professional financial software and are accurate for estimation purposes. However, actual results may vary based on your lender's specific policies, payment timing, and any fees. Always verify important decisions with your lender.
It depends on your personality and situation. Choose Avalanche if you want to save the most money and can stay motivated mathematically. Choose Snowball if you need quick wins to stay motivated or if your interest rates are similar. Both methods work - the best one is the one you'll stick with.
Use conservative estimates for your extra payments based on your typical lowest income months. You can always make larger payments when you have extra money, but it's better to under-promise and over-deliver to yourself than to set unrealistic expectations.
