Debt Payoff Planner: Excel debt snowball and avalanche calculator with month-by-month schedule (US, UK, EU, Canada, Australia, South Africa)

Find out exactly when you will be debt-free, and which plan costs you the least interest.

Enter your debts once (balance, interest rate and minimum payment) and the extra you can afford each month. The planner runs a true month-by-month payoff schedule three ways and compares them:

Avalanche: highest interest rate first, usually the least interest overall.

Snowball: smallest balance first, for quicker early wins.

Minimums only: what happens if you change nothing.

For each plan you see the months to debt-free, your debt-free date, total interest, total paid and the interest you save. A table shows the month each debt is cleared, and a chart shows your total debt falling over time.

How it works: every open debt gets its minimum each month, and the debt first in line gets everything else. When a debt is cleared its payment rolls on to the next one, which is the snowball effect. Schedules run for up to 10 debts and 30 years, and you can change the start month.

Six editions included: US dollar, Canadian dollar, Australian dollar, British pound, euro and South African rand. Comes with sample debts so you can see how it works. No macros, no subscription. Built for Microsoft Excel and works in every Excel version. Instant download.
