Back end gross
Back end gross explained: what counts as back end, and what does not
Back end gross is the profit a dealership makes from everything sold alongside the vehicle rather than from the vehicle itself. It comes mainly from finance reserve, service contracts and protection products, and it is reported per retail unit as F&I income, or F&I gross, per vehicle retailed.
You will hear it called back gross, F&I gross, or simply "the back". In US reporting the per-unit version is often written PVR, per vehicle retailed.
How is back end gross calculated?
Back end gross equals total finance and insurance gross profit divided by the number of retail units delivered in the period. The components usually counted:
- Finance reserve. The margin between the buy rate a lender quotes and the contract rate the customer signs, within whatever cap the lender or the regulator sets.
- Service contracts. Extended warranty and maintenance plans, counted at the retail price minus the cost of the plan.
- Protection products. GAP, tyre and wheel, paint and fabric, key replacement, and similar.
- Flat fees. A fixed amount some lenders pay per funded contract instead of reserve.
What normally does not count: documentation fees where local rules classify them separately, and anything the store has to reserve against for early cancellation. Chargebacks on cancelled contracts hit back gross in the month they land, not the month the deal was written, which is why a strong week can be reversed later.
Back end gross: a worked example
The same used SUV that sold for $32,400 goes out with $700 of finance reserve, an $850 margin on the service contract and $150 on GAP. Back end gross on that deal is $1,700.
Across a month of 120 deliveries the store books $204,000 of F&I gross, which is $1,700 of back end gross per unit. Two cancellations the following month claw $600 back, so the reported figure moves even though nothing changed in how the deals were sold.
How back end gross differs from front end gross
Front end gross is the metal. Back end gross is everything sold with it. Together they make gross profit per unit, and the two halves have been moving in opposite directions for several years.
The Q2 2026 Presidio-NCM Average Dealership Performance Benchmark recorded F&I income per retail unit of $1,769, up 4.8% year over year and the highest quarterly figure in the history of that report. In the same quarter gross profit per new vehicle retailed fell 13.5% to $1,840. Back end is now within touching distance of front end at the average franchised store.
That shift changes how a dealer principal should read a month. When vehicle margin is compressing, total gross can hold steady on the strength of the back end, and the store looks stable right up until F&I penetration slips.
Why back end gross varies so much between stores
- Credit mix. Cash and near-cash buyers produce no reserve. A store with heavy cash volume reports lower back gross on identical selling skill.
- Lender caps and local rules. Reserve caps differ by lender and by market, and the rules on how F&I products may be presented differ by country. Comparing US and UK back end figures directly is a mistake.
- New versus used. Presidio-NCM reports F&I per retail unit blended across new and used, so a store's own new-only or used-only figure will not match the benchmark.
- Brand segment. In Q2 2026 that benchmark showed F&I gross of $1,856 at luxury dealerships, $1,654 at import stores and $1,866 at domestic stores. The spread is far tighter than it is on the front end.
- Cancellation reserve. Product sales that cancel at a high rate inflate one quarter and deflate the next two.
What a dealer principal should actually watch
Back gross per unit on its own is a weak signal, because it moves with credit mix. The penetration rates behind it are the better read: what share of deliveries took finance, what share took a service contract, what share took GAP. Those three tell you whether the number is a process or an accident.
The other check is durability. Back end gross that survives the cancellation window is real money. Back end gross that reverses six weeks later was a timing entry. Track it alongside unit sales so you can see whether the F&I result is being carried by volume or by performance per deal.
