Example: The customer added a $22k battery to their system and but the total cost is showing as $32,467.53. The dealer fee for that lending option is 32.24%.
Calculation for the dealer fees on this adder would be: adder cost / (100 - dealer fee %) = X , and then X - adder cost = dealer fee amount
100 - 32.24 = 0.6776
$22,000 / 0.6776 = $32,467.53
$32,467.53 - $22,000 = $10,467.53
