Important Notes — 2025/26 Rates & Caveats
New car franchised dealers in the UK typically earn 7–15% front-end margin on new vehicles, often supplemented by manufacturer bonuses (holdback, stocking support, target bonuses) that can add 3–8%. Finance commission (consumer credit) is a significant income stream — the FCA's 2021 ban on discretionary commission arrangements (DCAs) changed the landscape; dealers now earn fixed flat-fee commissions on PCP and HP. Used car margin varies widely: specialist independents targeting premium used vehicles often achieve 15–25% gross. Trade-to-retail margin on auction purchases is typically 20–35% for volume independents.
Frequently Asked Questions
What is a typical gross margin on a new car for a UK franchised dealer?
Franchised dealers in the UK typically earn 7–15% front-end gross on new cars, before manufacturer bonuses. However, bonuses tied to volume targets (quarterly, annual) can be transformative — achieving target bonuses can add several thousand pounds per unit in a good quarter. Total gross (front + back-end F&I income) on a new car is typically £1,000–£3,500 for volume models, and £3,000–£10,000+ on premium or luxury vehicles.
How has the FCA ban on discretionary finance commissions affected dealers?
The FCA banned discretionary commission arrangements (DCAs) in January 2021, ending the practice where dealers could increase the interest rate on customer finance deals in exchange for higher commission. Dealers now earn fixed flat commissions on PCP and HP agreements. The FCA launched a wider review in 2024 into historical DCAs — some lenders face significant redress liability. Dealers should review their F&I income forecasts in light of the ongoing review and potential compensation claims.
What is the difference between front-end and back-end gross at a car dealer?
Front-end gross is the profit made on the vehicle itself — the difference between the retail selling price and the cost of acquiring and preparing the car. Back-end gross (or F&I income) is the profit earned from finance products (PCP, HP), insurance (GAP, tyre and alloy, cosmetic repair), service plans and extended warranties sold at the point of sale. High-performing dealers often earn as much or more from back-end products as from the vehicle itself.
