Car Loan Calculator

Use this calculator to estimate a car loan payment from the vehicle price, down payment, trade-in value, tax, fees, interest rate, and term. It helps you understand both the amount financed and the monthly payment before buying a vehicle.

What this calculator does

The car loan calculator estimates vehicle financing cost.

It uses:

• vehicle price
• down payment and trade-in
• sales tax and fees
• rate and loan term

The result shows the amount financed, estimated monthly payment, and total interest.

How to use the car loan calculator

Enter the vehicle price, down payment, trade-in value, sales tax percentage, fees, interest rate, and loan term in months. The calculator subtracts down payment and trade-in value after adding tax and fees.

Use the result to compare different vehicle prices, loan terms, or down payment amounts.

Car Loan Formula

Amount financed = vehicle price + tax + fees - down payment - trade-in value

Monthly payment = P x [r(1+r)^n] / [(1+r)^n - 1]

Example calculation

If:

• Vehicle price = 30,000
• Down payment = 4,000
• Trade-in value = 2,000
• Tax and fees = 3,000

Then:

Amount financed = 30,000 + 3,000 - 4,000 - 2,000 = 27,000

That amount is then amortized over the loan term.

What is a car loan?

A car loan is financing used to purchase a vehicle. The lender pays for the car upfront, and the borrower repays the financed amount with interest over time.

The vehicle often secures the loan, which means missed payments can put the vehicle at risk.

Interpreting your result

The amount financed is important because it drives both payment and total interest. A larger down payment or trade-in can lower borrowing cost.

When to use this calculator

• estimate car payment
• compare vehicle prices
• test down payments

Common mistakes

Common mistakes include:

• ignoring fees and tax
• focusing only on payment

FAQs

Does this include sales tax?

Yes, if you enter a sales tax percentage.

Does a larger down payment help?

Yes. It reduces the amount financed and usually lowers interest.

Is this the same as an auto loan payment?

It is similar, but this calculator also includes price, tax, fees, and trade-in.

Is this financial advice?

No. It is a planning estimate only.
