Your figures

Updates as you type
Formatting only. This does not change the calculation.
Negative equity is rolled into the new loan.
State-branded variants pre-fill the state base rate on vehicle purchases as a starting point. Counties and cities frequently add to it, and several states use a separate vehicle excise or title tax instead, so confirm the rate for your address.
Applied after tax, reducing the amount financed.
The nominal annual rate (APR before fees), not the monthly rate.
Added to the term in years, for terms such as 5 years and 6 months. To state a tenure purely in months, set the years to 0 and enter the whole tenure here.
Additional principal paid on top of the scheduled payment.

How this is worked out

4 steps
  1. Taxable amount = price minus trade-in = 45000
  2. Sales tax at 0% = 0
  3. Amount financed = price 45000 + tax 0 + fees 0 - rebate 0 - down 5000 - trade equity 0 = 40000
  4. Payment on 40000 at 7.5% = 370.8
