Formula Used

The auto loan calculation uses the standard loan payment formula:

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

Where:

P = Principal loan amount (Vehicle price - Down payment)
r = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
n = Number of payments (Loan term in years × 12)

This formula accounts for the interest you'll pay over the life of the loan.

Worked Example

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

Principal = $25,000 - $5,000 = $20,000
Monthly rate = 4.5% ÷ 12 = 0.375%
Number of payments = 5 × 12 = 60
Monthly payment = $20,000 × (0.00375 × (1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $382.50

Total interest paid over 5 years would be approximately $1,800.

Understanding Your Results

Your calculation results include:

Monthly payment - The amount you'll pay each month
Total interest - The total interest paid over the loan term
Total cost - The sum of your principal and total interest

Use these numbers to compare different loan options and make an informed decision.
