How to Use This Calculator

To use the Louisiana auto loan calculator:

The calculator will display your estimated monthly payment, total interest paid over the life of the loan, and the total amount you'll pay for the vehicle.

Formula Used

The calculator uses the standard auto loan payment formula:

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

Where:

P = Principal loan amount (Purchase Price - Down Payment)
r = Monthly interest rate (Annual Rate / 12)
n = Number of payments (Loan Term in Years × 12)

Total Interest = (Monthly Payment × n) - P

Total Amount Paid = Monthly Payment × n

Worked Example

Let's calculate a loan for a $25,000 vehicle with a 10% down payment, 5-year term, and 4.5% APR.

Down Payment = $25,000 × 10% = $2,500
Principal = $25,000 - $2,500 = $22,500
Monthly Rate = 4.5% / 12 = 0.00375
Number of Payments = 5 × 12 = 60
Monthly Payment = $22,500 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $423.50
Total Interest = ($423.50 × 60) - $22,500 ≈ $1,430
Total Amount Paid = $423.50 × 60 ≈ $25,430

This example shows that with these terms, you would pay approximately $423.50 per month, totaling $25,430 over the life of the loan with $1,430 in interest.
