Debt Payoff Tracker — Snowball and Avalanche Method for Google Sheets
The Debt Payoff Tracker helps you clear credit cards, loans, and any other balance faster by giving you a clear plan. Enter your debts and your monthly payment, choose the snowball or avalanche method, and the tracker projects your debt-free date and the interest you will save. It works in Google Sheets and Excel.
Choose Your Strategy: Debt Snowball or Debt Avalanche
The tracker supports both of the popular payoff strategies and lets you compare them side by side. You list every debt with its balance, interest rate, and minimum payment, then decide how much extra you can put toward debt each month. The sheet handles the ordering and the maths for whichever method you pick.
How the Debt Snowball Method Works
The snowball method pays the smallest balance first while paying minimums on the rest, then rolls that freed-up payment onto the next-smallest debt. It is the method many people stick with because each balance you fully clear is a visible win. The tracker shows how quickly those wins add up.
How the Debt Avalanche Method Saves More Interest
The avalanche method targets the debt with the highest interest rate first, which mathematically costs you the least in total interest. The tracker calculates exactly how much interest the avalanche order saves compared with the snowball order, so you can make an informed choice between the cheaper plan and the more motivating one.
Track Credit Cards, Student Loans, and Any Debt
You can list any kind of debt — credit cards, a car loan, student loans, a personal loan, or money owed to family. Each one has its own row with balance, rate, and payment, and the tracker keeps a running total so you always know how much is left across everything.
See Your Debt-Free Date Before You Start
Before you make a single payment, the tracker projects the month you will be debt-free based on your chosen method and extra payment. Increase the extra amount and watch the date move closer — it is a clear way to see the payoff of finding a little more room in your budget.

Frequently Asked Questions
Snowball vs avalanche — which should I use?
Avalanche saves the most interest because it targets your highest rate first. Snowball clears small balances first for quick motivation. The tracker shows both side by side, so you can see the interest difference and pick the plan you will actually stick to.
Does it calculate my debt-free date automatically?
Yes. Based on your balances, interest rates, minimum payments, and any extra you add, the tracker projects the month you will be debt-free. Change the extra payment and the date updates immediately.
Can I track more than one credit card?
Yes. You can list as many debts as you like — credit cards, student loans, car loans, personal loans — each on its own row, and the tracker totals them and orders them for your chosen method.
Does it work in Excel as well as Google Sheets?
Yes. The tracker opens in Microsoft Excel and imports into Google Sheets, and the calculations behave the same in both.
