How do I adjust the Financing Program Dealer Fee to Account for End User Sales Tax?

How do I adjust the Financing Program dealer fee for end-user sales tax? (Fig. 1)

Use this adjustment when you display end-user sales tax on the customer quote.

If your dealer fee is 7% and your sales tax is 6%

Multiply 7% x 6% to get 0.42% and add it to your dealer fee.

Your adjusted dealer fee becomes 7.42%
