How Does a Google Mortgage Payment Calculator Work?

Mortgage Payment Formula

The Google Mortgage Payment Calculator uses the standard mortgage formula:

$M = P \times \frac{r(1+r)^n}{(1+r)^n-1}$M=P×(1+r)n−1r(1+r)n​

Where:

• M = Monthly mortgage payment
• P = Loan principal
• r = Monthly interest rate (annual rate ÷ 12)
• n = Total number of payments

This formula ensures accurate estimation of fixed monthly mortgage payments.

Example of Mortgage Calculation

Let’s assume a borrower enters:

• Loan amount: $500,000
• Interest rate: 5%
• Loan term: 30 years

Estimated Results:

• Monthly payment: ≈ $2,684
• Total repayment: ≈ $966,240
• Total interest: ≈ $466,240

Insight:

Although the loan is $500,000, nearly double is repaid due to long-term interest accumulation.
