1. What is the Loan Payment Formula?

The loan payment formula calculates the fixed monthly payment required to fully repay a loan over its term, including both principal and interest. This is the standard formula used for most fixed-rate home equity loans.

2. How Does the Calculator Work?

The calculator uses the loan payment formula:

Where:

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

Explanation: The formula accounts for compound interest over the life of the loan, calculating a fixed payment that will pay off both principal and interest by the end of the term.

3. Importance of Loan Payment Calculation

Details: Understanding your monthly payment helps with budgeting and ensures you can comfortably afford the loan. It also allows you to compare different loan offers.

4. Using the Calculator

Tips: Enter the principal amount in USD, annual interest rate as a percentage (e.g., 5.25), 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. Your actual payment may include additional amounts for taxes and insurance.

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

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

Q4: Can I use this for adjustable-rate loans?
A: This calculator is for fixed-rate loans only. Adjustable-rate loans have payments that can change over time.

Q5: How accurate is this calculator?
A: It provides precise calculations for fixed-rate loans, but actual lender payments may vary slightly due to rounding methods.
