Example Calculation

Let’s understand how the calculator works with a real-life example.

Scenario:

  • Vehicle Price: $30,000
  • Down Payment: $5,000
  • Interest Rate: 6% APR
  • Loan Term: 60 months
  • Sales Tax: 8%
  • Fees: $1,000

Step-by-Step Result Breakdown:

  1. Base loan amount after down payment:
    $30,000 – $5,000 = $25,000
  2. Add taxes (8%):
    $25,000 × 8% = $2,000
  3. Add fees:
    $2,000 + $1,000 = $3,000 extra cost
  4. Total loan amount:
    $28,000
  5. Monthly payment (approx.):
    Around $540–$560 depending on interest compounding
  6. Total repayment over 60 months:
    Approximately $32,500–$33,500

This example shows how additional costs significantly affect the final amount you pay.
