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. It accounts for the principal amount, interest rate, and loan duration to determine consistent payments.

2. How Does the Calculator Work?

The calculator uses the standard mortgage payment formula:

Where:

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

Explanation: The formula accounts for compound interest over the life of the loan, ensuring each payment covers both principal and interest.

3. Importance of Mortgage Calculation

Details: Accurate mortgage calculations help borrowers understand their financial commitments, compare loan options, and budget effectively for home ownership.

4. Using the Calculator

Tips: Enter the loan amount in dollars, annual interest rate as a percentage (e.g., 3.5 for 3.5%), loan term in years, and select your state for potential rate adjustments.

5. Frequently Asked Questions (FAQ)

Q1: Why does the calculator ask for state?
A: Mortgage rates can vary by state due to local taxes, insurance requirements, and market conditions.

Q2: Does this include taxes and insurance?
A: No, this calculates principal and interest only. Your actual payment may include escrow for taxes and insurance.

Q3: How does loan term affect payments?
A: Shorter terms mean higher monthly payments but less total interest paid. Longer terms reduce monthly payments but increase total interest.

Q4: What's the difference between fixed and adjustable rates?
A: This calculator assumes a fixed rate. Adjustable rates would require more complex calculations as rates change over time.

Q5: How accurate is this calculator?
A: It provides accurate estimates for fixed-rate mortgages, but actual lender offers may vary based on credit score and other factors.
