The calculator will display your monthly payment, total interest paid over the loan term, and the total amount repaid.
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
- r = 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 specified term.
Worked Example
Let's calculate a $40,000 loan at 5.5% annual interest for 5 years:
- Principal (P) = $40,000
- Annual interest rate = 5.5% → Monthly rate (r) = 5.5%/12 = 0.004583
- Loan term = 5 years → Number of payments (n) = 5 × 12 = 60
Plugging these into the formula:
Monthly Payment = $40,000 × (0.004583(1 + 0.004583)^60) / ((1 + 0.004583)^60 - 1)
Calculating this gives a monthly payment of approximately $734.50.
Over 5 years, you would pay a total of $44,070, with $4,070 going to interest.

Frequently Asked Questions
What is the difference between APR and interest rate?
The interest rate is the cost of borrowing, while APR (Annual Percentage Rate) includes additional fees and costs associated with the loan. APR is always higher than the interest rate.
How does a longer loan term affect my monthly payment?
A longer loan term means lower monthly payments but more total interest paid over the life of the loan. A shorter term results in higher monthly payments but less total interest.
Can I pay off my auto loan early without penalty?
Most auto loans allow prepayment without penalty. Paying off early can save you money on interest, but check your loan agreement for any prepayment penalties.
What happens if I miss a car payment?
Missing a payment can result in late fees, damage to your credit score, and potential repossession if payments remain unpaid. Contact your lender immediately if you're having trouble making payments.
