Frequently Asked Questions
What types of loans does this cover?
Any fixed-rate loan with regular payments - personal loans, auto loans, equipment financing, or any other installment loan.
Can I enter the term in months?
Yes. The calculator accepts months or years. A 3-year loan can be entered as 36 months or 3 years.
Does a longer term lower the payment?
Yes. A longer term spreads payments over more months, reducing each payment. However, total interest increases because you are borrowing for a longer period.
Is this the same as an amortization calculator?
It calculates the payment amount. For a full month-by-month amortization schedule, use the Loan Amortization template.
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.
