Debt Payoff Tracker (Pro) — Snowball vs Avalanche Google Sheets + Excel Calculator with Debt-Free Date
Advanced debt payoff calculator for Google Sheets & Excel. A real month-by-month engine: switch between Snowball and Avalanche, auto-rolls freed-up minimums, and projects your exact debt-free date, total interest and each debt's payoff month. Add an extra payment and watch the savings. Tracks up to 8 debts.
See the exact date you'll be debt-free — and how much interest you'll save. This isn't a static worksheet; it's a real month-by-month payoff engine. Enter your debts, pick a strategy, add an extra payment, and watch your debt-free date and total interest recalculate instantly. Works in Google Sheets and Excel.
What makes it powerful:
- Snowball vs Avalanche — switch strategy with one dropdown (smallest balance first, or highest interest first) and compare the results side by side.
- Automatic rollover — as each debt is cleared, its minimum payment rolls onto the next debt, exactly like the real debt-snowball method.
- Debt-free date & total interest — a live projection across up to 10 years, updated the moment you change a number.
- Extra-payment power — add any extra amount and instantly see how many months and how much interest you save.
- Per-debt payoff timeline — the exact month each debt disappears, in priority order.
- Dashboard & balance chart — total debt, monthly payment, payoff order and a balance-over-time graph.
Tracks up to 8 debts. Every figure is a live formula — nothing hardcoded — so it's yours to reuse for years. Yellow cells show exactly what to fill in. Delivered as an .xlsx: open in Excel, or import to Google Sheets via File ▸ Import ▸ Replace spreadsheet.
