How to Use This Calculator

To use the Auto Trader Loan Calculator:

Select the loan term in years (e.g., 5 years)
Click the Calculate button

The calculator will display your monthly payment, total interest paid, and loan payoff date.

Formula Used

This calculator uses the standard car loan payment formula:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Principal loan amount
r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
n = Number of payments (loan term in years × 12)

The calculator also calculates the total interest paid by subtracting the loan amount from the total of all monthly payments.

Worked Example

Let's calculate a loan with these parameters:

Loan amount: $25,000
Annual interest rate: 4.5%
Loan term: 5 years

Using the formula:

Monthly interest rate = 4.5% ÷ 12 ÷ 100 = 0.00375

Number of payments = 5 × 12 = 60

Monthly payment = $25,000 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1)

Monthly payment ≈ $452.34

Total interest paid = ($452.34 × 60) - $25,000 ≈ $1,120.20

For this loan, you would pay approximately $452.34 per month, with a total interest of $1,120.20, and the loan would be paid off in 5 years.

Understanding Your Loan Terms

When using this calculator, it's important to understand the key terms:

Loan Amount: The total amount you're borrowing
Interest Rate: The annual percentage rate charged by the lender
Loan Term: The length of time to repay the loan
Monthly Payment: The amount you pay each month
Total Interest: The total amount paid in interest over the life of the loan

Remember that lower interest rates and shorter loan terms can significantly reduce your total interest payments.
