Main Mortgage Calculator

Mortgage Calculator With Taxes & PMI

Use this mortgage calculator to estimate monthly home loan payments with principal, interest, taxes, insurance, PMI, HOA fees, total interest, and amortization details.

Use the calculator near the top of the page, review the summary table, then change one input at a time to compare realistic scenarios before making a final decision.

What is the Main Mortgage Calculator?

A mortgage calculator estimates the monthly cost of a home loan and helps compare how home price, down payment, interest rate, term, taxes, insurance, PMI, and fees affect the payment.

It turns common planning inputs into a clear estimate before you compare options, speak with a professional, or decide what fits your situation.

What a standard mortgage means

A mortgage is a home loan used to buy or refinance a property. The borrower usually repays the loan through monthly payments that include principal and interest, while taxes, insurance, escrow, PMI, or other local costs may be added separately.

This mortgage calculator focuses on the core home loan estimate. It shows you monthly mortgage payment, home loan cost, interest impact, and payoff time before they compare lender offers.

How to use the Main Mortgage Calculator

Start with realistic numbers. If you do not know an exact value yet, use a careful estimate and update it later when you have a quote, statement, pay record, tax document, or provider figure.

  1. Enter the home price, down payment, loan term, and interest rate.
  2. Add property tax, home insurance, PMI, HOA, or fee estimates if available.
  3. Review the monthly payment, total interest, and amortization details.
  4. Change one input at a time to compare payment scenarios.

Example

For example, a user can open the Mortgage Calculator, enter a realistic loan balance and rate, then compare the result with another payment scenario. This makes it easier to see whether the option fits the monthly budget before you make a decision.

Mortgage payment formula

M = P × r(1 + r)^n / ((1 + r)^n - 1)
  • M = monthly principal and interest payment
  • P = loan principal
  • r = monthly interest rate
  • n = number of monthly payments

This formula estimates principal and interest only. Taxes, insurance, PMI, escrow, and lender fees can change the real monthly housing cost in the US, UK, and other markets.
