1. What is the House Note Formula?

The House Note formula calculates the fixed monthly payment required to fully amortize a loan over its term. This formula is widely used for mortgage calculations and other installment loans.

2. How Does the Calculator Work?

The calculator uses the House Note formula:

Where:

• \( M \) — 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 calculates the fixed payment that covers both principal and interest over the loan term, ensuring the loan is fully paid off by the end of the term.

3. Importance of Monthly Payment Calculation
