800 000 Mortgage Calculator

Calculating mortgage payments is a crucial step in understanding your financial commitments when purchasing a property. Our 800,000 Mortgage Calculator simplifies this process by providing you with an estimate of your monthly payment based on the loan amount, interest rate, and loan term.

Formula: The formula used to calculate the monthly mortgage payment is derived from the amortization formula:



  • M = Monthly Payment
  • P = Loan Amount
  • r = Monthly Interest Rate (annual interest rate divided by 12)
  • n = Total number of payments (loan term in years multiplied by 12)

How to Use:

  1. Enter the loan amount in dollars.
  2. Input the annual interest rate in percentage.
  3. Specify the loan term in years.
  4. Click the “Calculate” button to see your estimated monthly payment.

Example: Suppose you are considering a mortgage of $800,000 with an interest rate of 4.5% and a loan term of 30 years. Upon entering these values into the calculator and clicking “Calculate,” you would find your monthly payment to be approximately $4,052.96.
