Ask two installers what a full-body paint protection film job costs them in materials and the answers will differ by a factor of two. Ask them how they know, and one will say he divides the roll price by the number of cars he got out of it, and the other will say he does not really know but it feels like about right.
Cost per vehicle is the number that decides whether a PPF business makes money, and it is arithmetic rather than opinion. It has five inputs: the price of a roll, the yield from that roll, the labour hours per car, the rework rate, and the scrap that cannot be recovered. This article works through each one, shows how they combine, and sets out the pricing consequence that most workshops miss.
The reference product is the SUMEI range from Hangzhou Xingtuxintong Automotive Technology Co., Ltd.: X Series on Covestro aliphatic TPU in 6.5, 7.5, 8.5 and 9.5 mil, F Series on BASF aliphatic TPU at the same four thicknesses, and D Series with hydrophobic options in the same ladder. Because the series differ in price and in workability, the cost calculation has to be done per series rather than per brand.
The five inputs, and which one people get wrong
Four of the five inputs are measured. The one that is estimated, and then estimated optimistically, is yield.
| Input | How it is obtained | Common error |
|---|---|---|
| Roll price | Invoice price per roll, landed cost including freight and duty | Using the ex-works price and forgetting freight |
| Yield | Square metres of usable film obtained per roll, from actual jobs | Using the nominal roll area instead of the usable area |
| Labour hours | Clock time per vehicle, including prep and disassembly | Counting only the film application time |
| Rework rate | Percentage of panels redone, from a job log | Not measuring it at all |
| Scrap and offcuts | Film bought minus film installed, over a period | Treating offcuts as free because they were paid for already |
Nominal roll area is the trap. A 1.52 m by 15 m roll contains 22.8 square metres. Usable area is less, because the first and last metre behave differently, the edge strip is often unusable after slitting tolerance, and any defect found during installation costs the panel. A workshop that budgets on 22.8 and gets 18 will believe its margin is 20 percent when it is single digits.
Yield: how many cars come out of a roll
Yield per car is not a property of the film alone. It depends on vehicle size, on how the pattern is nested, and on whether the job is a full body or a partial coverage package. A roll that covers three large SUVs will cover four or five compact hatchbacks.
| Job type | Film typically used | Notes on nesting |
|---|---|---|
| Full body, large SUV | 18 to 22 square metres | Bonnet and roof panels are the yield constraint; nesting order matters more than on small cars |
| Full body, mid-size saloon | 16 to 19 square metres | Four doors and two wings can usually be nested side by side |
| Full body, compact hatchback | 13 to 16 square metres | Highest yield per roll; good vehicle for training and for volume packages |
| Front-end package | 5 to 7 square metres | Bonnet, guards, bumper, mirrors, headlights |
| Track package | 3 to 4 square metres | Leading edges, sills, mirrors, boot lip |
The practical rule for a roll budget: assume 16 square metres of usable film from a 22.8 square metre roll on a first calculation, then replace that assumption with the workshop's own measured figure after twenty jobs. Sixteen is deliberately conservative — it accounts for end trim, one panel's worth of rework per roll, and nesting loss on awkward patterns.
Nesting is where a plotter pays for itself. Cutting patterns that share cut lines between panels, and ordering the cut so that the largest panels come from the centre of the roll, recovers two to four square metres per roll compared with cutting panel by panel. If the workshop still cuts from templates by hand, this is the single largest cost improvement available before anything else changes.
Labour: the input that dominates
On most jobs labour is 50 to 70 percent of the true cost, which is why a discussion about film price alone rarely changes profitability. The hours are not only the hours of applying film.
| Stage | Full body, hours | Front-end package, hours |
|---|---|---|
| Wash, decontamination, paint assessment | 3 to 5 | 1.5 to 2.5 |
| Disassembly: handles, lights, badges, trim | 2 to 4 | 1 to 2 |
| Pattern cutting and preparation | 1 to 2 | 0.5 to 1 |
| Film application | 12 to 20 | 4 to 7 |
| Reassembly and quality check | 2 to 3 | 1 to 1.5 |
| Total | 20 to 34 | 8 to 14 |
A full body in twenty hours is a good day with two people and a car that comes apart easily. Thirty-four hours is a car with complex bumpers, a matte finish that shows every handling mark, or an installer still learning the pattern. Both are real numbers, and quoting from the lower one on every job is how a workshop ends up busy and unprofitable.
The thickness affects hours as well as price. A 9.5 mil film is stiffer and holds a shape better on deep recesses but demands more pressure and more slip solution on compound curves; a 6.5 mil film conforms faster but shows handling marks sooner. In the SUMEI ladder this is visible in the tensile and elongation figures — 23.9 MPa and 240 percent at X1 rising to 30.4 MPa and 300 percent at X7 — and it is one reason a premium tier is not simply a more expensive version of the entry tier.
Rework: the invisible third of the cost
Rework is expensive twice: the film is consumed and the labour is repeated, while the first attempt's hours are already sunk. A rework rate of 8 percent on a twenty-five hour job adds two hours and one panel of film to the average car, even though the job that goes well shows neither.
- Measure it. Keep a log of panels redone, with the reason. Reasons cluster: contamination under the film, edge lift after a week, stretch marks on a compound curve, silvering on a dark panel.
- Separate installer error from product behaviour. Silvering on a gloss black panel at 8.5 mil is a technique and thickness interaction; edge lift on every car from one batch is a product issue. The two need different responses.
- Charge the film, not the customer. Budget rework into the price rather than absorbing it as a surprise. A price built on a 5 percent rework allowance is defensible; one built on zero is a promise the workshop cannot keep.
Edge lift and its prevention are covered in installation, thickness and environment, and the failure modes that show up after the car leaves are covered in aliphatic versus aromatic TPU.
Putting the numbers together
With the five inputs, the cost per vehicle is a short calculation. The example below is illustrative and uses round numbers so the structure is visible; substitute the workshop's own figures.
| Line | Full body, mid-size saloon | Basis |
|---|---|---|
| Film consumed | 18 sq m | Includes one reworked panel allowance |
| Usable film per roll | 16 sq m | Measured, not nominal |
| Roll price, landed | 1,200 | Invoice plus freight and duty |
| Film cost per car | 1,350 | 18 divided by 16, times roll price |
| Labour hours | 27 h | All stages, including prep and reassembly |
| Labour cost per car | 810 | 27 h at a costed hourly rate of 30 |
| Consumables | 60 | Slip solution, squeegees, blades, towels, tape |
| Overhead allocation | 150 | Bay, power, rent share per job |
| Cost per vehicle | 2,370 | Before margin and tax |
Two observations follow from the structure rather than the figures. First, film is roughly 57 percent of that cost, so a ten percent film saving moves the total by less than six percent — while a ten percent labour improvement moves it by three and a half percent, and both are worth less than removing one reworked panel per car. Second, the hourly rate used for labour must be the costed rate, not the wage: rent, tools, insurance and idle time all have to land somewhere, and if they do not land in labour they will not land at all.
From cost to price
Cost per vehicle is only half the decision. The other half is the margin the market will bear at that coverage level, and the coverage level customers actually buy.
- Choose the coverage package before the price. Front-end and track packages carry a higher film cost per square metre because the offcuts cannot be nested into anything, but they convert better and take less bay time. Most workshops should sell more partial coverage than they do.
- Price the series, not the brand. A 6.5 mil entry film and a 9.5 mil premium film differ in both material cost and hours. Quoting one price for "full body PPF" hides that and destroys the premium margin.
- Quote in coverage, not by vehicle model alone. Two cars of the same model differ in condition, and the prep stage is where that shows.
- Review the calculation quarterly. Roll prices, labour rates and rework rates all drift; a price list built on last year's inputs is a slow leak.
Choosing the series mix in the first place is a separate exercise, covered in range tiers and inventory. What matters here is that the series choice is made with the yield and labour numbers in front of you, because a premium film that adds two hours per car and two square metres of scrap may cost more than its price suggests.
What the supplier can and cannot fix
When cost per vehicle is too high, the instinct is to negotiate the roll price. That is the smallest lever. The larger ones are yield and rework, and both depend on things a supplier can support but not deliver on the buyer's behalf.
- Ask for the usable area, not the nominal area. A supplier who states how many square metres a working shop gets from a roll is describing the product honestly.
- Ask for patterns in the nesting-friendly format the workshop's plotter uses, with cut lines shared between adjacent panels.
- Ask about batch consistency, because a change in adhesive behaviour mid-shipment shows up as rework rather than as a defect.
- Ask for retained samples per batch, so a rework spike can be attributed to technique or to product with evidence.
