1. What is the Home Loan Payment Formula?

The home loan payment formula calculates the fixed monthly payment required to fully repay a loan over its term, including interest. This is the standard calculation used for most mortgages in Washington state.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

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

Explanation: The formula accounts for both principal repayment and interest charges, calculating a fixed payment that fully amortizes the loan over its term.
