1. What is Auto Loan Interest Calculation?

Auto loan interest calculation determines the total interest paid over the life of an auto loan using amortization principles. It helps borrowers understand the true cost of financing a vehicle beyond the principal amount.

Where:

• \( EMI \) — Equated Monthly Installment (currency units)
• \( m \) — Number of months (unitless)
• \( P \) — Principal loan amount (currency units)
