The mortgage payment formula calculates the fixed monthly payment required to fully amortize a loan over its term. This calculation is particularly useful for home buyers in Washington State to estimate their monthly housing costs.

2. How Does the Calculator Work?

The calculator uses the standard mortgage formula:

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

Where:

$ PMT $ — Monthly payment amount
$ P $ — Principal loan amount
