Monthly Budget & Debt Payoff Spreadsheet (Debt Snowball / Avalanche Calculator)

Monthly budget template with a built-in debt snowball and avalanche payoff calculator for Excel and Google Sheets.

A straightforward spreadsheet for planning your money month by month, seeing the whole year at a glance, and comparing two common debt payoff methods. All totals and calculations are built in with formulas, so you only type your own numbers. Example data is highlighted in yellow and labeled "(example)" so you can see how it works before replacing it.

What's included:

• Instructions tab explaining every section
• 12 monthly budget tabs (Jan to Dec), each with income and expense categories, planned vs. actual, differences and remaining balance
• Category dropdown lists (you can also type your own categories)
• Annual Overview that fills in automatically from the monthly tabs, with year totals, monthly averages, running net and an income vs. spending chart
• Debt Payoff calculator for up to 15 debts: snowball vs. avalanche, payoff month per debt, months to debt-free, total interest and interest saved
• Extra monthly payment input that links into each month's budget
• Payoff chart showing total debt remaining over time for both methods
• Savings Goals tracker for up to 8 goals
• Print-ready: every tab fits the page width

Format: one .xlsx file. Works in Microsoft Excel and imports into Google Sheets (File > Import).

Note: results are estimates based on the numbers you enter. This is a planning tool, not financial advice. Digital download only.
