Formula Used

The mortgage payment calculation follows the standard amortization formula:

Mortgage Payment Formula

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

  • P = Principal loan amount
  • r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
  • n = Number of payments (loan term in years × 12)

The property taxes are added to the monthly payment as an additional expense.

The total interest paid is calculated by subtracting the original loan amount from the total amount paid over the life of the loan.

Worked Example

Let's look at an example to understand how the calculator works. Suppose you're taking out a $200,000 mortgage at 4.5% annual interest with a 1.2% property tax rate.

  1. Loan amount: $200,000
  2. Annual interest rate: 4.5%
  3. Property tax rate: 1.2%

After running these numbers through the calculator, you'll see:

  • Monthly payment: $1,342.45
  • Total interest paid: $102,938.00
  • Total amount paid: $302,938.00

This example shows that over 15 years, you'll pay $1,342.45 per month, with $102,938.00 going toward interest.

Interpreting Results

When you use this mortgage calculator with taxes, pay attention to these key results:

  • Monthly Payment: This is the amount you'll pay each month, including principal, interest, and property taxes.
  • Total Interest Paid: This shows how much of your total payment goes toward interest over the life of the loan.
  • Total Amount Paid: This is the sum of all your monthly payments, including interest and taxes.

Understanding these numbers helps you make informed decisions about your mortgage and financial planning.
