Understanding the Auto Loan Calculator

Review the inputs, outputs, calculation method, and formulas used by this tool.

Input parameters

Auto Price
The negotiated vehicle purchase price.
Down Payment
The amount or percentage paid upfront.
Interest Rate
The annual percentage rate used in the calculation.
Loan Term
The length of time allowed to repay the loan.
Trade-in Value
Credit received for the traded vehicle.
Sales Tax
The sales-tax rate applied to the taxable price.
Title, Registration and Other Fees
Upfront vehicle fees included in financing.

Understanding the results

Monthly payment
Estimated principal-and-interest payment.
Amount financed
Taxable vehicle cost and fees after down payment and trade-in.
Total interest
Finance charge paid over the term.

Calculation principle

The net vehicle cost, tax, and fees determine the financed principal, which is amortized with equal monthly payments.

  1. Read and validate the entered values.
  2. Convert percentages and time periods into compatible units.
  3. Apply the formulas below and present the calculated results.

Formulas

Amount financed P = (Price − Trade-in) × (1 + Tax rate) + Fees − Down payment
Monthly payment PMT = P × r(1 + r)^n / ((1 + r)^n − 1)

Symbols refer to the corresponding input and result labels shown above.

How to use this calculator

Enter your figures, choose any available options, and select Calculate. You can change the inputs as often as you like to compare scenarios.
