1. What is the Home Loan Payment Formula?

The PMT formula calculates the fixed monthly payment required to repay a home loan over a specified period, including both principal and interest components.

2. How Does the Calculator Work?

The calculator uses the standard payment formula:

Where:

• \( P \) — Principal loan amount (USD)
• \( r \) — Monthly interest rate (decimal)
• \( n \) — Number of monthly payments

Explanation: The formula accounts for the time value of money, calculating equal payments that will pay off the loan plus interest over the loan term.

3. Importance of Accurate Payment Calculation

Details: Knowing your exact monthly payment helps with budgeting and comparing different loan options. Even small rate differences can significantly impact your monthly payment.

4. Using the Calculator

Tips:

• Enter the total loan amount (after down payment)
• Convert APR to monthly rate by dividing by 12 (e.g., 6% APR = 0.06/12 = 0.005)
• Number of payments is loan term in years × 12
