Debt Payoff Tracker (Snowball + Avalanche)

The debt snowball and the debt avalanche are both real, proven ways to pay off debt faster — they just rank your debts in a different order. Most trackers make you pick one and do the math yourself. This one runs both.

Enter your debts once — balance, interest rate, minimum payment. Pick Snowball (smallest balance first) or Avalanche (highest interest rate first) from a dropdown, set how much extra you can put toward debt each month, and the workbook re-ranks your payoff order instantly and runs the real math behind it: a month-by-month payoff simulation that rolls each paid-off debt's minimum payment into the next one, the way the method is actually supposed to work. Months to debt-free and total interest paid update live, so you can compare both strategies before committing to one.

Then log your real balance once a month in the Progress Tracker and watch the payoff bar fill in. A plain-English Instructions tab walks through Snowball vs. Avalanche and how to read your results. Works in Excel, Google Sheets, and LibreOffice Calc.
