1. What is the Loan Payment Formula?

The loan payment formula calculates the fixed monthly payment required to fully repay a loan with interest over a specified term. This is known as the PMT (payment) formula in financial mathematics.

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)
• \( n \) — Number of monthly payments (term in years × 12)
• \( PMT \) — Monthly payment amount (USD)

Explanation: The formula accounts for both the principal repayment and the interest charges over the life of the loan.

3. Importance of Loan Payment Calculation

Details: Understanding your monthly payment helps with budgeting and financial planning. It also allows you to compare different loan offers and terms.

4. Using the Calculator

Tips: Enter the principal amount in USD, annual interest rate as a percentage, and loan term in years. 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 portion of a loan payment. Other costs like property taxes or insurance would be additional.

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 interest.

Q3: What's the difference between APR and interest rate?
A: APR includes both interest rate and loan fees, giving a more complete picture of loan cost. This calculator uses the interest rate.

Q4: Can I use this for any type of loan?
A: This works for standard fixed-rate loans (mortgages, auto loans, personal loans). It doesn't work for adjustable-rate or interest-only loans.

Q5: How accurate is this calculator?
A: It provides exact calculations for fixed-rate loans. Actual lender payments may vary slightly due to rounding methods or additional fees.
