Scenario: A dealer sells a used car for $25,000, finances it through a lender, and earns a $1,200 finance commission. The vehicle’s cost was $21,000, with $500 in reconditioning and $150 in administrative fees.

Step-by-step calculation (Step-by-Step: Instantly Calculate Dealer Profit Margin—No Guesswork, Precise Results):

  1. Total Income: Sale price ($25,000) + finance commission ($1,200) = $26,200
  2. Total Expenses: Vehicle cost ($21,000) + reconditioning ($500) + admin fees ($150) = $21,650
