How Auto Loan Calculations Work

Auto loan calculations use the standard loan amortization 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 × 12)

This formula calculates the fixed monthly payment required to fully amortize the loan over the selected term.

Key Assumptions

  • Fixed interest rate throughout the loan term
  • No prepayment penalties
  • No additional fees or taxes
  • Monthly compounding of interest

Worked Example

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

Monthly payment = $25,000 [ (0.045/12)(1 + 0.045/12)^60 ] / [ (1 + 0.045/12)^60 - 1 ]

Calculated monthly payment = $476.54

Total interest paid = $3,782.60

Final payoff date = Approximately 5 years from today

Frequently Asked Questions

What is the difference between APR and APY?
APR (Annual Percentage Rate) is the simple interest rate, while APY (Annual Percentage Yield) includes compound interest. APY will always be higher than APR for the same loan.
How does loan term affect my monthly payment?
A longer loan term means lower monthly payments but higher total interest paid. A shorter term means higher monthly payments but lower total interest.
Can I pay off my loan early without penalties?
Keesler Federal Credit Union typically allows prepayment without penalties, but it's best to check your loan agreement for specific terms.
