Frequently Asked Questions

What is PMI?

PMI (Private Mortgage Insurance) is typically required when your down payment is less than 20% of the home price. It protects the lender and usually costs 0.5%–1.5% of the loan amount annually.

What is a good interest rate for a mortgage?

Interest rates change constantly based on economic conditions. As of 2024–2025, 30-year fixed rates in the US typically range from 6% to 7.5%. A rate 0.5% lower can save tens of thousands over the life of a loan.

What is the difference between a 15-year and 30-year mortgage?

A 15-year mortgage has higher monthly payments but you pay roughly half the total interest. A 30-year mortgage has lower monthly payments but costs significantly more in interest over time.

How is monthly payment calculated?

The formula is M = P × [r(1+r)^n] / [(1+r)^n − 1] where P is the loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the total number of payments.

What is an amortization schedule?

An amortization schedule shows each payment broken down into principal and interest portions. Early payments are mostly interest; later payments are mostly principal. This tool shows both annual and monthly views.

Does this include taxes and insurance?

Yes — enter property tax, home insurance, PMI, and HOA to see your complete PITI (Principal, Interest, Tax, Insurance) payment. These are optional fields.
