Enter the purchase price of the vehicle in the "Vehicle Price" field.
Select your state from the dropdown menu to automatically apply the correct sales tax rate.
Enter any additional fees such as title fees, license fees, and registration fees.
Input your down payment amount if you're making one.
Enter the loan term in years.
Select the interest rate for your loan.
Click "Calculate" to see your estimated monthly payment.

The calculator will display your total monthly payment including principal, interest, taxes, and other fees.

Formula Used

The auto payment calculator uses the following formula to calculate your monthly payment:

Monthly Payment Formula

Monthly Payment = [P × (r(1 + r)^n) / ((1 + r)^n - 1)] + (Taxes + Fees)/n

Where:

P = Principal loan amount (Vehicle Price - Down Payment)
r = Monthly interest rate (Annual Rate / 12)
n = Number of payments (Loan Term × 12)
Taxes = Sales tax on vehicle price
Fees = Title fees + License fees + Registration fees + Other fees

This formula accounts for both the loan repayment and the additional costs associated with purchasing a vehicle.

Worked Example

Let's walk through an example to see how the calculator works.

Example Scenario

Vehicle Price: $25,000
State: California (7.25% sales tax)
Title Fee: $100
License Fee: $50
Registration Fee: $75
Down Payment: $3,000
Loan Term: 5 years
Interest Rate: 4.5%

Calculation Steps

Calculate sales tax: $25,000 × 7.25% = $1,812.50
Total additional fees: $100 (title) + $50 (license) + $75 (registration) = $225
Principal loan amount: $25,000 (price) + $1,812.50 (tax) + $225 (fees) - $3,000 (down) = $24,037.50
Monthly interest rate: 4.5% / 12 = 0.375%
Number of payments: 5 years × 12 = 60 months
Calculate monthly loan payment using the formula: $24,037.50 × (0.00375(1 + 0.00375)^60) / ((1 + 0.00375)^60 - 1) ≈ $420.50
Total monthly payment: $420.50 (loan) + ($1,812.50 + $225)/60 ≈ $420.50 + $33.50 = $454.00

The calculator would show a monthly payment of approximately $454.00 for this scenario.
