1. What is the Mortgage Payment Formula?

The mortgage payment formula calculates the fixed monthly payment required to fully amortize a loan over its term. This standard formula is used by lenders throughout Washington state to determine monthly mortgage payments.

2. How Does the Calculator Work?

The calculator uses the standard mortgage payment formula:

\[ PMT = P \times \frac{r \times (1 + r)^n}{(1 + r)^n - 1} \]

Where:

$ PMT $ — Monthly payment
$ P $ — Principal loan amount
$ r $ — Monthly interest rate (annual rate ÷ 12)
$ n $ — Total number of payments (loan term in years × 12)

Explanation: The formula accounts for both principal repayment and interest charges, with payments structured so the loan is paid off exactly at the end of the term.
