Frequently Asked Questions
What is the difference between snowball and avalanche?
Snowball pays off the smallest balance first for quicker wins. Avalanche targets the highest interest rate first to minimize total interest paid.
How many debts can I enter?
The template supports multiple debts. Add rows to the debt setup sheet for each account - credit cards, loans, medical bills, or any other debt.
Does it show total interest paid?
Yes. The dashboard shows total interest for both the snowball and avalanche strategies so you can compare the cost of each approach.
Can I add extra payments later?
Yes. Update the extra payment amount at any time and the entire payoff schedule recalculates with the new amount.
How do I open this in Google Sheets?
Upload the .xlsx file to Google Drive, then open it with Google Sheets. All formulas and formatting will be preserved.
