About Debt Payoff Calculator
The Debt Payoff Calculator runs your debt list through both the avalanche and snowball strategies and shows which clears faster and cheaper. Enter each debt's balance, APR and minimum payment plus any extra you can pay monthly; the simulation accrues interest month by month, targets one debt at a time and rolls freed-up minimums into the next, then reports the debt-free date, months, total interest and total paid for each method, the interest avalanche saves, and the order your debts disappear in. No figures leave your browser.
Use Cases
How to use
Fill the Your Debts table with a Name, Balance, Interest Rate and Min Payment for each account. Press + Add Debt for another row or the red cross to delete one.
Enter the Extra Monthly Payment you can put toward your debts on top of all the minimums.
Compare the Avalanche Method card, which attacks the highest interest rate first, against the Snowball Method card, which clears the smallest balance first.
Read Debt Free Date, Total Interest and Total Paid on each card, and the green banner showing how much interest Avalanche saves over Snowball.
Select the radio button on the strategy you want, then follow the numbered Payoff Order list to see which debt to target first and its projected payoff date.
