How Auto Loan Payments Are Calculated

Auto loan payments are calculated using the standard loan amortization formula:

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

Where:

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

This formula calculates the fixed monthly payment required to pay off the loan in the specified term. The payment includes both principal and interest components.

For loans with down payments, the principal amount (P) is reduced by the down payment amount before applying the formula.

Example Calculation

Let's calculate the monthly payment for a $25,000 auto loan with a 4.5% annual interest rate over 5 years:

Principal (P) = $25,000
Annual interest rate = 4.5% or 0.045
Monthly interest rate (r) = 0.045 / 12 ≈ 0.00379
Number of payments (n) = 5 × 12 = 60

Plugging these values into the formula:

Monthly Payment = $25,000 × (0.00379 × (1 + 0.00379)^60) / ((1 + 0.00379)^60 - 1)

Monthly Payment ≈ $454.24

So, the monthly payment for this loan would be approximately $454.24.

Compare different loan options to find the best deal:

Loan Amount	Interest Rate	Term (Years)	Monthly Payment	Total Interest

$25,000	3.9%	5	$442.86	$1,426.60
$25,000	3.9%	4	$615.04	$2,100.80

This table shows how different interest rates and loan terms affect your monthly payment and total interest paid. Shorter terms generally result in higher monthly payments but less total interest.
