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.

2. How Does the Calculator Work?

The calculator uses the mortgage payment formula:

Where:

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

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

3. Importance of Mortgage Calculation

Details: Accurate mortgage calculation helps borrowers understand their financial commitments, compare loan options, and plan their budgets effectively.

4. Using the Calculator

Tips: Enter the loan amount in USD, monthly interest rate as a decimal (e.g., 0.005 for 0.5%), and loan term in months. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I convert APR to monthly rate?
A: Divide the annual percentage rate by 12 (months) and convert to decimal (e.g., 6% APR = 0.06/12 = 0.005 monthly rate).

Q2: How do I convert years to months?
A: Multiply the number of years by 12 (e.g., 30 years = 360 months).

Q3: Does this include taxes and insurance?
A: No, this calculates only principal and interest. Actual mortgage payments may include additional amounts for taxes and insurance.

Q4: What's the difference between fixed and adjustable rates?
A: Fixed rates remain constant, while adjustable rates may change after an initial period, affecting future payments.

Q5: How can I pay less interest overall?
