- Select your loan term in years
- Input your estimated annual percentage rate (APR)
- Enter any down payment amount
- Add any additional taxes and fees
- Click "Calculate" to see your results
The calculator will display your estimated monthly payment, total interest paid, and total cost of the loan including taxes and fees.
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 (after down payment)
- i = Monthly interest rate (APR/12/100)
- n = Number of payments (loan term in years × 12)
The total cost of the loan includes the sum of all monthly payments plus any additional taxes and fees you enter.
Worked Example
Let's calculate a loan with these parameters:
- Loan amount: $25,000
- Down payment: $3,000
- Loan term: 5 years
- APR: 4.5%
- Additional taxes and fees: $1,200
First, calculate the principal loan amount after down payment: $25,000 - $3,000 = $22,000
Monthly interest rate: 4.5% ÷ 12 = 0.375% or 0.00375
Number of payments: 5 × 12 = 60
Using the formula:
M = $22,000 [ 0.00375(1 + 0.00375)^60 ] / [ (1 + 0.00375)^60 - 1 ]
Calculating this gives a monthly payment of approximately $402.50
Total interest paid over 5 years: $402.50 × 60 - $22,000 = $5,700
Total cost including taxes and fees: ($402.50 × 60) + $1,200 = $25,900
Interpreting Results
When you use this calculator, you'll receive several key pieces of information:
- Monthly Payment: The amount you'll pay each month
- Total Interest: The total amount of interest you'll pay over the life of the loan
- Total Cost: The sum of all monthly payments plus any additional taxes and fees
These figures help you understand the true cost of financing your vehicle and make comparisons between different loan options.
Important Note
This calculator provides an estimate. Your actual payments may vary based on your lender's specific terms and any additional fees that aren't included in the estimate.
Frequently Asked Questions
What is included in the APR?
The Annual Percentage Rate (APR) includes the interest rate charged by the lender plus any additional fees that are rolled into the loan. These fees are typically expressed as an annual percentage of the loan amount.
How do taxes and fees affect my monthly payment?
Additional taxes and fees are added to the total cost of the loan but are not included in the monthly payment calculation. They are typically paid upfront or at the time of purchase.
Can I refinance my auto loan to lower my payments?
Yes, refinancing can help lower your monthly payments if interest rates have decreased or if you qualify for a better loan term. However, you'll need to consider the costs of refinancing, including fees and potential impact on your credit score.
What happens if I miss a payment?
Missing a payment can result in late fees, damage to your credit score, and potentially lead to repossession of the vehicle if payments remain unpaid. It's important to make payments on time to avoid these consequences.
