What is a Mortgage Calculator?

A mortgage calculator estimates your monthly payment for a home loan. It considers principal & interest and can include property tax, insurance, and HOA fees.

How Mortgage Payments Work

With a fixed-rate mortgage, monthly principal+interest stays constant, while the interest portion declines over time as the loan balance decreases.

Formula Explanation

Monthly Payment = P × r / (1 − (1 + r)^−n), where P is the loan amount, r is the monthly rate, and n is the number of payments.
