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 the consistent payment amount.

2. How Does the Calculator Work?

The calculator uses the standard mortgage payment formula:

Where:

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

Explanation: The formula calculates the fixed payment needed to pay off the loan completely by the end of the term, including both principal and interest.

3. Importance of Mortgage Calculation

Details: Understanding your mortgage payment helps with budgeting, comparing loan options, and making informed decisions about home affordability. It shows the long-term cost of borrowing.

4. Using the Calculator

Tips: Enter the loan amount in dollars, 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: What's included in a typical mortgage payment?
A: This calculator shows principal and interest. Actual payments may include property taxes, insurance, and PMI if applicable.

Q2: How does loan term affect payments?
A: Shorter terms mean higher monthly payments but less total interest paid. Longer terms lower monthly payments but increase total interest.

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

Q4: How often are mortgage payments compounded?
A: Most mortgages use monthly compounding, meaning interest is calculated monthly on the remaining balance.

Q5: Can I pay off my mortgage early?
A: Yes, but check for prepayment penalties. Extra payments reduce principal faster and save on interest.
