Assumptions

  • Sales tax is applied to the whole price, fees are added to the loan, and what is owed on the trade-in is rolled into the loan. A lender may treat these differently.
  • The result is an estimate from the numbers you enter.

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

How it works

The payment pays off an amount A = payment x (1 - (1 + r)^-n) / r, where r is the APR / 12. $500 a month for 60 months at 6% pays off $25,862.78.

The price is then (A + down payment + trade-in value - amount owed on the trade-in - fees) / (1 + tax rate): ($25,862.78 + $3,000 - $500) / 1.07 = $26,507.27.

Putting that price back into the Car Loan Calculator gives a $500.00 payment again.

Formulas and details
  • r = APR / 100 / 12; n = number of monthly payments; M = the payment you want.
  • Loan it pays off A = M x (1 - (1 + r)^-n) / r (at 0%, A = M x n).
  • Price = (A + down payment + trade-in value - amount owed on the trade-in - fees) / (1 + sales tax rate).

Assumptions

  • Sales tax is applied to the whole price, fees are added to the loan, and what is owed on the trade-in is rolled into the loan. A lender may treat these differently.
  • The result is an estimate from the numbers you enter.

Example

Input: The starting values already in the form

Result: A payment of $500.00 a month fits a vehicle priced up to about $26,507.00. Under these assumptions: 60 months at 6.00% APR, $3,000.00 down, 7.00% sales tax and $500.00 in fees.

Questions

What car price gives me a $500 payment?

With 6% for 60 months, $3,000 down, 7% sales tax and $500 of fees, about $26,500. Change the numbers for yours.

Why does a longer term raise the price that fits?

A longer term lowers the payment for the same price, so the same payment buys more, but you pay more interest over the loan.
