Explanation: This formula calculates the total interest paid over the life of the loan. For monthly payments, divide the result by the number of months in the loan term.
Details: Calculating interest helps you understand the true cost of your car loan, compare financing options, and make informed decisions about loan terms and down payments.
Tips: Enter the principal amount in dollars, interest rate as a decimal (e.g., 0.05 for 5%), and loan term in years. All values must be positive numbers.
                    Q1: Is this simple or compound interest?
                    A: This calculator uses simple interest. Most car loans use simple interest, meaning interest is calculated only on the principal balance.
                
                    Q2: How do I convert APR to decimal?
                    A: Divide the APR by 100. For example, 5% becomes 0.05.
                
                    Q3: Why is my actual interest different?
                    A: This is a simplified calculation. Actual loans may include fees, compounding, or amortization schedules that affect total interest.
                
                    Q4: How can I reduce total interest paid?
                    A: Make a larger down payment, choose a shorter loan term, or negotiate a lower interest rate.
                
                    Q5: Should I focus on monthly payment or total interest?
                    A: While monthly payments affect your budget, total interest shows the actual cost of borrowing. Consider both when choosing a loan.
