What it does

Works out the monthly payment, amount financed, interest and total cost of a car loan with down payment, trade-in, sales tax and fees.

How to use it

  1. Enter the vehicle price, your down payment and any trade-in and amount owed on it.
  2. Enter the sales tax rate, the fees, the interest rate (APR) and the term in months.
  3. Read the monthly payment first, then the amount financed, interest and total cost.

Enter your own rate: this page does not look it up and does not assume what is taxable.

Assumptions

  • Sales tax is applied to the whole price and added to the loan, and fees are added to the loan. Tax rules differ by place, so check yours.
  • A lender's figure can differ by a few cents because each payment is rounded.
  • The rate, tax and fees are the ones you enter: this page knows no rates.

Printed from oneclickanswers.com. Results are estimates based on what was entered; see the assumptions above.

How it works

The amount financed is the price + sales tax + fees - the down payment - the trade-in value + what is owed on the trade-in. On $30,000 at 7% with $500 of fees and $3,000 down it is $29,600.

The payment is the level-payment formula: P x r x (1 + r)^n / ((1 + r)^n - 1) with r = APR / 12; at 0% it is P / n. $29,600 at 6% for 60 months is $572.25.

Total of the payments is the payment times the months; interest is that minus the amount financed.

Formulas and details
  • r = APR / 100 / 12 (monthly rate); n = number of monthly payments.
  • Amount financed = price + sales tax + fees - down payment - trade-in value + amount owed on the trade-in.
  • Monthly payment M = P x r x (1 + r)^n / ((1 + r)^n - 1). When APR is 0%, M = P / n.
  • Total of the payments = M x n. Interest = total of the payments - P.

Example

Input: The starting values already in the form

Result: Your payment would be about $572.25 a month for 60 months. You would finance about $29,600.00, pay about $4,735.06 in interest, and about $37,335.06 in all, counting what you pay up front.

Questions

How much will a $35,000 car cost per month?

Enter 35,000 as the price with your own down payment, rate and term. At 6% for 60 months with nothing down and no tax or fees, it is about $677 a month.

What if I owe more on my trade-in than it is worth?

That negative equity is added to the loan, which raises the amount financed.

Can I compare two offers?

Yes: the Car Loan Comparison puts two or more offers side by side.
