1. What is the Loan Payment Formula?

The loan payment formula calculates the fixed monthly payment required to repay a loan over a specified term, including interest. It's commonly used for personal loans, auto loans, and mortgages.

2. How Does the Calculator Work?

The calculator uses the standard loan payment formula:

Where:

• \( P \) — Principal loan amount (USD)
• \( r \) — Monthly interest rate (annual rate ÷ 12, in decimal)
• \( n \) — Number of monthly payments (term in months)
• \( PMT \) — Fixed monthly payment amount (USD)

Explanation: The formula accounts for both principal repayment and interest charges, distributing payments evenly over the loan term.

3. Importance of Loan Payment Calculation

Details: Accurate payment calculation helps borrowers understand their financial commitments, compare loan offers, and budget effectively for repayment.

4. Using the Calculator

Tips: Enter the loan amount in USD, annual interest rate as a percentage, and loan term in months. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Does this include taxes and insurance?
A: No, this calculates only the principal and interest payment. Other costs may apply depending on the loan type.

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

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

Q4: Can I use this for credit card payments?
A: This formula works best for fixed-rate installment loans. Credit cards typically use different calculation methods.

Q5: How accurate is this calculator?
A: It provides accurate estimates for standard fixed-rate loans. Actual payments may vary slightly due to rounding or specific lender policies.
