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. This standard equation accounts for both principal and interest payments.

2. How Does the Calculator Work?

The calculator uses the mortgage payment formula:

Where:

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

Explanation: The formula calculates the fixed payment that pays off the loan with interest over the specified term.

3. Importance of Mortgage Calculation

Details: Understanding mortgage payments helps borrowers budget effectively, compare loan options, and make informed decisions about home purchases.

4. Using the Calculator

Tips: Enter the loan amount in USD, annual interest rate as a percentage (e.g., 3.5 for 3.5%), and loan term in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this include property taxes and insurance?
A: No, this calculates only principal and interest. A complete mortgage payment may also include taxes, insurance, and PMI.

Q2: How does the 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.

Q3: What's the difference between APR and interest rate?
A: The interest rate is the cost of borrowing, while APR includes fees and other loan costs to show the true annual cost.

Q4: Can I use this for other types of loans?
A: Yes, this formula works for any fixed-rate, fully amortizing loan (car loans, personal loans, etc.).

Q5: How can I pay less interest overall?
A: Make extra principal payments when possible, choose a shorter loan term, or secure a lower interest rate.
