Frequently Asked Questions
What does the monthly payment include?
The calculator shows Principal & Interest (P&I) plus any property tax, home insurance, and HOA fees you enter. These four components together are commonly called PITI.
What is PMI and is it included?
PMI (Private Mortgage Insurance) is typically required when the down payment is below 20%. This calculator does not include PMI — factor in roughly 0.5–1% of the loan per year if applicable.
Is my data sent to a server?
No. All calculations run locally in your browser. Your financial information is never uploaded or stored anywhere.
What is the difference between a 15-year and 30-year mortgage?
A 15-year mortgage has higher monthly payments but significantly lower total interest paid. A 30-year mortgage lowers monthly payments but costs substantially more in interest over the full term.
