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 installment 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, in decimal)
• \( n \) — Total number of payments (loan term in years × 12)
• \( PMT \) — Monthly payment amount (USD)

Explanation: The formula accounts for compound interest over the life of the loan, ensuring each payment covers both interest and principal.

3. Importance of Loan Payment Calculation

Details: Calculating accurate loan payments helps borrowers understand their financial commitments, compare loan offers, and budget effectively for major purchases like vehicles.

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.

Q3: 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.

Q4: Can I calculate total interest paid?
A: Yes, multiply the monthly payment by number of payments, then subtract the principal amount.

Q5: Are there prepayment penalties?
A: Some loans charge fees for early payoff. Check your loan agreement for details.
