The calculator will display your estimated monthly payment, total interest paid, and a breakdown of your loan payments over time.
Formula Used
The monthly payment for a car loan is calculated using the standard loan payment formula:
Monthly Payment = P × [r(1 + r)^n] / [(1 + r)^n - 1]
Where:
- P = Principal loan amount (car price)
- r = Monthly interest rate (annual rate divided by 12)
- n = Number of payments (loan term in years × 12)
This formula accounts for the interest you'll pay over the life of the loan and provides an accurate estimate of your monthly payments.
Worked Example
Let's say you want to buy a car for $25,000 with a 5-year loan at an annual interest rate of 4%. Here's how the calculation works:
- Convert the annual interest rate to a monthly rate: 4% ÷ 12 = 0.333% or 0.00333 in decimal form.
- Calculate the number of payments: 5 years × 12 = 60 payments.
- Plug the values into the formula:
Monthly Payment = $25,000 × [0.00333(1 + 0.00333)^60] / [(1 + 0.00333)^60 - 1]
- The calculation results in a monthly payment of approximately $452.36.
Using our calculator, you can quickly see how changing the loan amount, interest rate, or term affects your monthly payments.
Frequently Asked Questions
What is the difference between APR and interest rate?
APR (Annual Percentage Rate) is the cost of credit expressed as a yearly rate, while the interest rate is the actual rate charged on your loan. APR includes additional fees and costs, making it a more accurate representation of the total cost of borrowing.
How does a longer loan term affect my monthly payments?
A longer loan term means you'll make fewer monthly payments, but each payment will be larger because you're spreading the loan out over more time. This results in paying more interest over the life of the loan.
Can I pay extra toward my car loan?
Yes, paying extra toward your car loan can save you money on interest. Each additional payment reduces the principal balance faster, which can lower your total interest paid and shorten the loan term.
