Should your shop bring ADAS calibration in-house? The full Playbook.

Every month another ADAS equipment pitch lands in a shop owner's inbox. Six figures of targets, scan tools, and calibration hardware, with a payback story attached.

Most of those pitches start with the equipment cost. That is the wrong place to start.

What actually decides whether the build works is two things the pitch never asks about: what stage your shop is at, and whether you are capturing the ADAS work that is already walking through your door. Get those right and the equipment math answers itself. Get them wrong and the kit is the least of your problems.

Bringing ADAS calibration in-house is a capture-rate decision, not an equipment decision.

This piece walks the whole decision start to finish. If you would rather watch than read, the 90-second cycle-time math is embedded below in "The lever the static math leaves out," and the 5-step framework walkthrough is embedded in "The decision, in order." If you want to run the math on your own shop instead of mine, the calculator is at the bottom.

The gap most shops are deciding without

Start with the gap, because most shops are deciding without it.

About 65% of collision repairs need at least one ADAS recalibration. Industry calibration penetration sits around 28.3%. Subtract those and you get roughly 37 cars out of every 100 leaving body shops without a calibration the manufacturer says they needed.

For a shop running 56 repair orders a month, that is about 36 ADAS-affected jobs. Some get calibrated, in-house or sublet. A lot never get identified at all, which means they are not even in the decision yet.

So before the build-versus-sublet question makes any sense, you need your own number. How many ADAS-affected jobs come through your door a month, and how many are you actually catching at blueprinting. That is the foundation. Everything else is math built on top of it.

Two numbers, not one: capture rate vs in-house share

There are two distinct numbers that get conflated, and untangling them is where most of the decision lives.

Capture rate is the share of your ADAS-affected jobs you actually identify at blueprinting and bill the calibration on, whether you do the calibration in-house or sublet it. This is the number you control with process. Estimator training, blueprinting discipline, scan tool workflow at intake.

In-house share is the share of those captured calibrations you keep in-house instead of subletting out. This is the number you control with capital. Equipment, bay, tech.

These are different problems and they get fixed with different tools.

A shop doing 4 ADAS jobs in-house and hearing "Stage 2 breaks even at 6" assumes it has a volume problem. But that same shop is often seeing 25 or 30 ADAS-affected jobs a month and either missing them at blueprinting or subletting almost every one of them. That is not a volume problem. That is a capture problem and a keep problem stacked on top of each other, and both get fixed with process before they get fixed with capital.

The math lives in jobs, and the answer changes by stage

What follows is the operating math: what the build throws off in monthly cash before you account for what the equipment costs. The equipment cost shows up in its own section after.

Your vendor bills you per calibration. You run your shop per job. The average ADAS-affected job needs about 1.8 calibrations, which at industry midpoint rates is about $490 of calibration revenue per job. Framed per job, it stops looking like a vendor line item and starts looking like a revenue stream you can model against fixed cost.

REVV's 2026 survey maps a five-stage capability curve. Most shops sit at Stage 1 or 2. The equipment pitches assume Stage 4. The math at those stages is not the same math.

Stage 2 is simple calibrations in-house, basic tools, existing techs who likely have excess capacity and can be trained up. The threshold is plain: it breaks even at about 6 in-house ADAS jobs a month. Six jobs covers the roughly $1,250 a month in software and OEM access, given about $203 of margin per job over what subletting already pays you.

Stage 3-4 is a dedicated bay and a dedicated tech. Now the tech is fixed cost instead of per-job cost, and fixed cost jumps to about $9,500 a month. The threshold moves with it: Stage 3-4 breaks even at about 26 in-house ADAS jobs a month.

Those two numbers, 6 and 26, are the real "does the math work" line. Not a percentage. A car count. If you want the simplest possible version of this decision, that is it: count your in-house ADAS jobs and compare them to the threshold for the stage you are weighing.

There is an honest exception. Some shops cannot reach 26 jobs at any capture rate or any in-house share, because their total ADAS-affected volume is below 26 to begin with. For those shops Stage 3-4 is not a problem to go solve. It is simply not the move, and Stage 2 is the ceiling.

The equipment is the easy part

Now the equipment, which is where the pitches start and should be where you finish.

REVV's 2026 benchmark puts the median shop's calibration equipment investment around $55,000. Not six figures. The range runs roughly $30,000 to $120,000, and a $120,000 quote is the top of that range, not the middle of it. A Stage 2 setup is closer to $25,000. A Stage 3-4 setup runs $50,000 to $80,000.

Whether that money is well spent comes down to payback, and payback follows directly from the car count.

At Stage 2, a $25,000 kit at 50% in-house share, about 18 jobs a month for the example shop, pays back in roughly 10 months. At 35% in-house share it stretches to about 18 months. Below that the volume barely covers the fixed cost and the kit never really pays for itself. The headline holds: for almost any shop with real ADAS volume, Stage 2 equipment pays back fast.

At Stage 3-4 it is a different story. A $65,000 kit at 72% in-house share, the 26-job breakeven, leaves about $68 a month after fixed costs. On a $65,000 kit, that is not a payback. It is a rounding error. You have to be running near 83% in-house share before it pays back in three-plus years, and near 90% before it comes in under three. On the headline math, Stage 3-4 only makes sense for shops already operating like Stage 4 shops.

But the headline math is not the whole math.

The lever the static math leaves out

The headline payback is operating-only and equipment-only. There is a third lever that can change the Stage 3-4 answer entirely, and it is the one most shops underweight: cycle-time.

When calibration stops being a sublet bottleneck, you get up to two days back of keys-to-keys on every ADAS-affected RO. That number comes from Mitchell and Mike Anderson's published cycle-time work. Those days are real. They only convert to dollars under one of two conditions.

One, your shop is capacity-bound. You are turning work away or stretching cycle on the cars you take, because you do not have the floor space or the production days to fit more. Days back on existing files free the capacity to take cars you currently cannot.

Two, you compete on cycle time. Your local market has shops running long on ADAS files and your shorter cycle pulls DRP scorecard position or steals cars from the slower competitor.

Under either condition, those days become incremental cars at full severity. A shop at $4,500 severity and 25% margin is talking roughly $1,125 of contribution per incremental car. A handful of those a month against a $65,000 Stage 3-4 kit changes the answer. Stage 3-4 payback that did not pencil at the threshold starts to.

Without one of those two conditions, the days back are goodwill. Real, but not cash. The headline payback stands.

So the honest version of Stage 3-4 has two cases. Base case, no conversion: the math stays tight, and the build only makes sense for shops already running like Stage 4 shops. Conversion case, capacity-bound or competitive cycle-time pull: the kit can pencil at in-house shares that the base case dismisses. The question to answer before signing the order is not whether you want the conversion. It is whether you actually have it.

The decision, in order

If you are weighing the ADAS build, here is the order I would work it:

1. What is your ADAS-affected job count? The jobs a month that need a calibration. That is your opportunity pool.
2. What is your capture rate? Of that pool, how many are you identifying at blueprinting and billing the calibration on, in-house or sublet.
3. What is your in-house share? Of those captured calibrations, how many do you keep versus sublet. That number drives the operating math.
4. What stage does your in-house volume actually justify? About 6 jobs for Stage 2, about 26 for Stage 3-4. If you cannot reach the threshold at a realistic capture and keep rate, that stage is not your move.
5. Does the equipment pay back, and do you have a lever that can bend it? Kit cost against the monthly cash the build throws off over sublet, then layer cycle-time on top. In-house calibration saves up to two days of keys-to-keys per ADAS-affected RO. Those days are cash if you are capacity-bound or competing on cycle time, goodwill if you are not. At Stage 3-4 this is the lever that can flip a build that did not pencil at the threshold.

Most shops that work this honestly land in the same place. Stage 2 is the move, and the first job is not buying equipment. It is raising the capture rate on the ADAS jobs already coming through the door.

Run it on your own shop (free calculator)

My example shop is not your shop. So I built the worksheet I would use sitting across from a client.

You put in your monthly repair orders, your capture rate, your in-house share, the stage you are weighing, and the kit price you have been quoted. It returns your ADAS opportunity pool, your in-house car count, whether you clear the threshold for that stage, and your equipment payback. It also runs the cycle-time math at a default of two days back per ADAS-affected RO (the Mitchell / Mike Anderson benchmark), which you can adjust or discount to zero if your shop's reality is different. Same math this Playbook walks, run on your numbers.
