Frequently asked questions
These questions cover the most common things people want to know before using a mortgage calculator.
FAQ
What does this mortgage calculator estimate?
It estimates the monthly payment for a fixed-rate mortgage, including principal and interest, property tax, homeowners insurance, PMI, and HOA dues. It also computes total interest paid over the life of the loan and the projected payoff date.
FAQ
What is PITI and what does the monthly payment include?
PITI stands for principal, interest, taxes, and insurance — the four standard parts of a typical monthly mortgage payment. This calculator also adds PMI when applicable and HOA dues if you enter them, since they affect the real total you pay each month.
FAQ
How is PMI handled?
PMI is calculated as an annual percentage of the original loan amount, divided into monthly installments, and is automatically removed from the projection once your remaining balance reaches 80% of the original home value. Many conventional loans allow PMI removal at 80% LTV, with automatic termination commonly occurring at 78% LTV.
FAQ
How accurate is the result?
The principal and interest portion is calculated using the standard amortization formula and is accurate to the cent for a fixed-rate loan. Property tax, insurance, PMI, and HOA are estimates based on the values you enter — your real lender quote may differ slightly because of escrow timing, lender fees, and discount points.
FAQ
What's the difference between a 15-year and a 30-year mortgage here?
A 15-year loan has a higher monthly payment but a much lower total interest cost, because the principal is paid down faster. A 30-year loan has a lower monthly payment but you pay more interest overall. Switch the loan term in the calculator to see the trade-off side by side.
FAQ
