Formula Used

The auto loan calculator uses the standard loan payment formula:

Loan Payment Formula

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ]

Where:

  • M = Monthly payment
  • P = Principal loan amount
  • i = Monthly interest rate (APR/12)
  • n = Number of payments (loan term in years × 12)

This formula calculates the fixed monthly payment required to pay off a loan with a fixed interest rate over a specified period.

Worked Example

Let's calculate a $25,000 auto loan with a 4.5% APR over 5 years:

  1. Principal (P) = $25,000
  2. Annual interest rate = 4.5% or 0.045
  3. Monthly interest rate (i) = 0.045/12 ≈ 0.003792
  4. Loan term in months (n) = 5 × 12 = 60

Plugging these values into the formula:

Calculation Steps

M = 25000 [ 0.003792(1 + 0.003792)^60 ] / [ (1 + 0.003792)^60 - 1 ]

M ≈ $454.23 per month

Total interest paid = $454.23 × 60 - $25,000 ≈ $1,745.80

Total amount paid = $25,000 + $1,745.80 ≈ $26,745.80

Interpreting Results

When you use this auto loan calculator, you'll receive several key pieces of information:

  • Monthly Payment: The amount you'll pay each month
  • Total Interest: The total interest you'll pay over the life of the loan
  • Total Amount Paid: The sum of your principal and total interest

These figures help you understand the true cost of your auto loan and make informed financial decisions.
