1. What is the Auto Loan Payment Formula?

The auto loan payment formula calculates the fixed monthly payment required to pay off a car loan over a specified term, including the cost of full coverage insurance.

2. How Does the Calculator Work?

The calculator uses the auto loan payment formula:

Where:

• \( PMT \) — Monthly payment
• \( P \) — Principal loan amount
• \( insurance \) — Monthly full coverage insurance cost
• \( r \) — Monthly interest rate (annual rate ÷ 12)
• \( n \) — Number of monthly payments

Explanation: The formula accounts for both the loan principal and insurance costs, calculating the fixed payment needed to pay off the loan over the specified term.

3. Importance of Full Coverage Insurance

Details: Full coverage insurance is typically required for financed vehicles and includes comprehensive and collision coverage in addition to liability.

4. Using the Calculator

Tips: Enter loan amount in dollars, monthly insurance cost in dollars, annual interest rate as a decimal (e.g., 0.05 for 5%), and loan term in months.
