Debt Payoff Planner — Snowball & Avalanche Calculator Spreadsheet
See your debt-free date — and what an extra $50 a month changes.
List your debts once. Choose snowball (smallest balance first) or avalanche (highest interest first). The planner builds a month-by-month payoff schedule and shows the date each debt is paid, so you can compare methods in seconds.
What it does
- Up to 8 debts: credit cards, car loans, personal and student loans
- Debt-free date, months to go and total interest at the top
- Rollover built in: when one debt is paid, its payment moves to the next
- Full 30-year month-by-month schedule
- Flags any debt whose minimum payment doesn't cover its interest
Good to know
Estimates assume a fixed APR, monthly interest and no new charges, so your lender's figures may differ slightly. This is a planning tool, not financial advice.
