Frequently Asked Questions
What types of loans does this work for?
Any fixed-rate, fully amortizing loan - mortgages, personal loans, auto loans, or business loans. Enter the terms and the schedule generates automatically.
Can I enter the term in months?
Yes. The setup accepts months or years. A 5-year loan can be entered as 60 months or 5 years.
Why does the principal portion grow each month?
As the balance decreases, less of each payment goes to interest and more goes to principal. This is how standard amortization works.
Does it handle extra payments?
This template generates a standard amortization schedule without extra payments. For extra payment modeling, use the Mortgage Payoff Calculator.
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.
