The ADAS Math Most Equipment Pitches Skip

There is roughly $2,400 a month in ADAS calibration margin sitting on the floor of the average mid-size body shop. Most owners I talk to are deciding what to do about it without seeing the math.

Most ADAS equipment pitches that land in shop owner inboxes assume you are already at Stage 4 capability. 62% of body shops are not. The math at each stage looks nothing like the math at Stage 4. The financial conclusion depends entirely on which stage your shop is actually at.

This post walks the math at two stages, with the operating-only caveat that equipment economics is its own layer covered separately.

The gap most shops do not measure

CCC published industry calibration penetration at 28.3 percent. REVV's 2026 survey of about 300 shops says 65 percent of repairs need at least one ADAS recalibration. Subtract those two and you get 37 cars per 100 walking out of body shops without a calibration the manufacturer says they needed.

For a mid-size shop doing 56 closed ROs a month, that is about 20 cars per month walking out under-calibrated. Front cameras that never got re-aimed after the windshield. Blind-spot sensors still pointed where the bumper used to be. Forward radar that thinks the world is a bumper-thickness off from where it actually is.

The first lever for most shops is identification at the blueprinting stage. Knowing which jobs in your shop actually need a calibration. Equipment and sublet vendor decisions come after that.

Per-cal vs per-job: the math lives in jobs

Your ADAS vendor bills you per calibration. You run your shop per job. That gap is where the math gets confused for most owners.

The average ADAS-affected job needs about 1.8 calibrations. First cal at full rate. Each one after at roughly half because the setup is amortized. The vehicle is prepped, the bay is configured, the paperwork is in motion. At REVV's industry midpoint, that is $350 for the first cal and $175 for each one after.

On a 1.8-cal average job, that is $490 per ADAS-affected job in calibration revenue.

In per-calibration terms, $350 sits next to the equipment quote and the quote looks bigger than the revenue. In per-job terms, $490 multiplied by every ADAS-affected job is a real revenue line you can model against fixed cost. Same math, two different feelings.

Per-cal is vendor pricing structure. Per-job is how you run the business. Frame the math in jobs and the decision stops feeling like the equipment quote.

Which stage are you actually on?

REVV's 2026 survey mapped a five-stage ADAS capability curve for body shops:

• Stage 1: fully sublet, no in-house process
• Stage 2: simple calibrations in-house, basic tools
• Stage 3: most calibrations in-house with real systems, capturing 50 to 80 percent of the work
• Stage 4: dedicated bays and tech, 90 percent plus in-house, capturing 80 to 95 percent
• Stage 5: serving as a sublet provider yourself, doing ADAS work for other shops

The distribution from REVV's survey: 42 percent of shops at Stage 1 or 2. 20 percent at Stage 3. 38 percent at Stage 4 or 5. Two-thirds of shops are in Stages 1 through 3.

Most ADAS equipment pitches sell shop owners the Stage 4 jump and skip the math at Stages 2 and 3 entirely. The math at those stages looks nothing like the math at Stage 4. The financial conclusion you reach depends entirely on which stage your shop is actually at when you do the math.

Stage 2 math: 6 jobs to break even on operating math

Stage 2 means doing simple calibrations in-house. Forward-facing cameras. Basic statics. Existing techs in slack time. The vendor still handles the complex multi-system work.

For our example shop with 56 closed ROs and about 36 ADAS-affected jobs available per REVV's data, here is the per-job math:

• Per-job revenue: $490
• Sublet baseline contribution: 25 percent of $490, or about $122 per job
• In-house labor at Stage 2: 3 hours of existing-tech time at $55 loaded, or $165
• In-house contribution: $490 minus $165, or $325 per job
• Incremental over the sublet baseline: $325 minus $122, or $203 per job

Stage 2 fixed cost is about $1,250 a month for software and OEM access. $1,250 divided by $203 incremental contribution per job is about 6 jobs.

Stage 2 breaks even at about 6 ADAS-affected jobs a month. For the example shop with 36 ADAS-affected jobs available, that is less than 1 in 5. Almost any shop with ADAS volume clears it.

Here is what 6 does not include: equipment investment. Targets, scan tools, the actual calibration hardware. That is a separate layer covered in next week's content. The operating answer at Stage 2 alone, before equipment, is that almost any shop with ADAS volume clears the screen.

Stage 3-to-4 math: 72 percent capture just to beat sublet

Stage 3 to 4 is the transition most ADAS equipment pitches actually sell. Dedicated bay, dedicated ADAS tech, 90 percent plus in-house including the complex multi-system work, OEM-backed documentation.

The structural change at this stage is the tech. Stage 2 uses existing techs in slack time, so labor is variable per job. Stage 3 to 4 means a dedicated ADAS tech on payroll. Once that tech is salaried, their time is fixed cost, not per-job cost.

For the same example shop:

• Per-job revenue stays at $490
• Per-job direct cost is consumables, which round to zero (the tech's time is now fixed)
• Contribution per job: the full $490
• Sublet baseline contribution: still $122 (25 percent of $490)
• Incremental over sublet: $490 minus $122, or $368 per job

Fixed costs at Stage 3 to 4 are software access at $1,500 a month plus the dedicated ADAS tech, fully loaded, at $8,000 a month. Total $9,500 a month, pre-financing.

$9,500 divided by $368 is about 26 jobs per month. For our example shop with 36 ADAS-affected jobs available, 26 jobs is 72 percent capture. That is the top of Stage 3's published capture range and approaching the bottom of Stage 4's. The Stage 3 to 4 math requires near-Stage-4 capture levels just for the operating math to beat sublet.

If your shop is doing fewer than 26 ADAS-affected jobs a month, the Stage 3 to 4 math does not work yet on operating math alone. For most shops, the biggest lever is still capture rate, not equipment. Fix the miss before deciding to build.

What is NOT in this math

Two important layers not yet priced in any of this week's content:

Equipment investment. Targets, scan tools, the actual calibration hardware. The $1,250 a month at Stage 2 and the $9,500 a month at Stage 3 to 4 cover software and labor only. Equipment financing changes the conclusion meaningfully, especially at Stage 3 to 4. That is next week's content.

Cycle-time credit. When calibration stops being a sublet bottleneck, the shop gets days back on every ADAS-affected RO. For shops with DRP scorecards or capacity-constrained operations, that is real economic value. It is not automatic. Doing the math on cycle-time savings requires real shop data on saved days, throughput conversion, and whether the saved days actually convert into more delivered ROs. That is also a near-term content layer.

Both of these change the conclusion. Stage 3 to 4 with equipment financing layered in looks different than the operating-only math above. Stage 2 with cycle-time credit layered in becomes even easier to clear.
