Frequently Asked Questions (FAQ)

How is the monthly mortgage payment calculated?

The monthly principal and interest payment is calculated using the standard formula: P * (r * (1 + r)^n) / ((1 + r)^n - 1), where P is the loan principal, r is the monthly interest rate (annual rate divided by 12), and n is the total number of monthly payments.

What is a down payment?

A down payment is the initial upfront cash portion of the purchase price of a home. The remaining home value is funded through your mortgage loan.

Should I include property taxes and insurance?

Yes, standard mortgage payments often include property taxes and home insurance (escrow). Our calculator allows you to input optional estimates for taxes, insurance, and HOA fees to see your complete monthly cost.

What is an amortization schedule?

An amortization schedule is a table showing each monthly payment over the life of the loan, detailing how much of each payment goes toward the loan principal versus interest.
