Frequently Asked Questions
How is the monthly mortgage payment calculated?
It uses the standard amortization formula based on the loan amount (home price minus down payment), interest rate, and loan term.
Does it include property tax and insurance?
No. The calculator shows principal and interest only. Your actual monthly payment may be higher when taxes, homeowners insurance, and PMI are included.
What is a typical down payment?
Conventional loans typically require 5-20% down. A 20% down payment avoids private mortgage insurance (PMI), which this calculator does not include.
How does the loan term affect my payment?
A longer term (30 years) means lower monthly payments but much more total interest paid. A 15-year mortgage has higher payments but saves significantly on total interest.
Is my financial data private?
Yes. All calculations happen in your browser. No financial data is sent anywhere.
Is the mortgage calculator free?
Yes. Completely free with no sign-up or account required.
