Formula Used

The monthly payment for an auto loan is calculated using the standard 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 (annual rate divided by 12)
  • n = Number of payments (loan term in years multiplied by 12)

Total interest is calculated as:

Total Interest = (Monthly Payment × Number of Payments) - Principal

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 ≈ 0.00375
  4. Loan term in months (n) = 5 × 12 = 60

Plugging these into the formula:

M = 25000 [ 0.00375(1 + 0.00375)60 ] / [ (1 + 0.00375)60 - 1 ] ≈ $463.50

Total interest paid would be:

Total Interest = (463.50 × 60) - 25000 ≈ $1,041.00

So your total repayment would be $26,041.00 over 5 years.

Frequently Asked Questions

What is the difference between APR and interest rate?

APR (Annual Percentage Rate) is the total cost of credit including all fees and charges, while the interest rate is the cost of borrowing without fees. APR is always higher than the interest rate.

How does loan term affect my monthly payment?

A longer loan term means lower monthly payments but more total interest paid. A shorter term means higher monthly payments but less total interest. Choose based on your budget and financial goals.

Can I pay extra toward my loan without penalty?

Yes, most auto loans allow prepayment without penalty. Paying extra principal can save you money on interest and shorten your loan term.
