1. What is a Louisiana Auto Loan Calculator?

Definition: This calculator estimates monthly payments for auto loans in Louisiana using the standard amortization formula.

Purpose: It helps Louisiana residents plan their car purchases by calculating expected monthly payments and total loan costs.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ M = P \times \frac{r(1 + r)^n}{(1 + r)^n - 1} \]

Where:

\( M \) — Monthly payment (USD)
\( P \) — Loan principal amount (USD)
\( r \) — Monthly interest rate (annual rate ÷ 12)
\( n \) — Number of payments (loan term in years × 12)

Explanation: This formula accounts for compound interest over the life of the loan to determine fixed monthly payments.
