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 (Car 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 used auto loan with these details:

  • Car Price: $15,000
  • Down Payment: $3,000
  • Loan Term: 5 years
  • Interest Rate: 5.5%

Principal (P) = $15,000 - $3,000 = $12,000

Monthly Interest Rate (r) = 5.5% / 12 ≈ 0.004583

Number of Payments (n) = 5 * 12 = 60

Monthly Payment = $12,000 * (0.004583(1 + 0.004583)^60) / ((1 + 0.004583)^60 - 1) ≈ $232.50

Total Interest = ($232.50 * 60) - $12,000 ≈ $1,950

Total Amount Paid = $232.50 * 60 ≈ $14,000

Comparison Table

Here's how different loan terms affect your payments:

Loan Term Monthly Payment Total Interest Total Amount Paid
3 years $325.12 $1,837.20 $13,837.20
4 years $275.45 $1,626.40 $13,626.40
5 years $232.50 $1,950.00 $14,000.00
6 years $202.25 $2,235.00 $14,235.00
7 years $179.12 $2,502.80 $14,502.80

This table shows how longer loan terms reduce monthly payments but increase total interest paid. Shorter terms save on interest but require larger monthly payments.
