In the first section of the calculator shown above, you can enter all of your current debts, including the balance, interest rate, and minimum payment. The “custom” column to the far right allows you to determine in what order you’ll pay down the debt, which comes into play with the next screen shot:
You’ll see a drop-down box with a label of “Strategy.” Here you can select from several debt snowball strategies (e.g., highest interest first, lowest balance first, etc.) or, using the Custom column from the first screen shot, pay off your debt in any order you want.
Plug in how much extra you’ll pay, if any, and the spreadsheet calculates when each debt will be paid and how much total interest you’ll pay. It’s a great tool to war game your debt snowball plan.
