Tool 01

Repair Range Estimator

Pick a damage scope, a unit size and an approximate parts figure. The tool applies the posted labor rates, the published materials formulas and the real parts markup policy to produce a planning band and an hour count. It runs in your browser and transmits nothing.

Labor hours

Total across trades, before any supplement.

Assumptions

  • Body and paint labor at the posted $210 per hour, mechanical and electrical at $260.
  • Paint supplies at $55 per paint hour, body supplies at $5 per body hour.
  • Parts markup applied at 100 percent at or under $100 and 35 percent above.
  • Sales tax at 7.75 percent on parts and materials. Labor is not taxed.
  • Hour bands come from measured shop history on comparable scope, scaled by unit size.
  • This is a planning band, not a quote. Teardown routinely changes scope on a specialty unit.

What the calculator is actually doing

The scope you pick maps to a low and high labor hour band drawn from shop history on comparable work. Those hours are multiplied by a size factor, because access scales faster than damage does. Reaching a crack on a forty foot coach costs more hours than reaching the same crack on a teardrop, and none of that extra time is visible in a photograph.

Body and paint hours bill at the posted body rate. Mechanical and electrical hours bill at the posted mechanical rate. Paint supplies calculate at a fixed figure per paint hour and body supplies at a fixed figure per body hour, exactly as they do on a real ticket. Parts get the published markup, and sales tax is applied to parts and materials only.

What the tool cannot model is the thing that most often moves a real ticket, which is what teardown finds. A photo estimate written before disassembly on a laminated unit is routinely short, and the gap is not a rounding error. It is frequently multiples. That gap is what a written supplement documents.

Use the output to decide the next move rather than to budget to the dollar. If the band says a job is a five figure structural repair rather than a four figure cosmetic one, that changes whether you file, whether you schedule around a trip, and whether the unit is worth keeping. Those are the decisions this is built for.

About this estimator

01Why is the range so wide?
Because scope is wide. A structural ticket on a large unit can be thirty labor hours or one hundred and ten depending on how far the damage travelled through the substrate, and that is genuinely unknown until panels come off. A narrow range here would be a more confident number and a less honest one.
02Does this replace a written estimate?
No. It places a job in an order of magnitude so you can decide what to do next, which is usually whether to file a claim, whether to schedule around a trip, or whether the unit is worth repairing. A written estimate after physical inspection is the only document that produces an actual figure.
03Where do the labor hours come from?
Measured shop history on comparable scope, scaled by unit size. Published repair times exist for common operations on common chassis, but a large share of specialty work has no published time at all. There is no book time for sectioning a discontinued front cap, so the hours come from jobs that resembled it.
04Why does unit size change the number so much?
Access scales faster than damage does. The same six inch crack takes longer to reach on a forty foot diesel pusher than on a teardrop, because more has to come off to get to it, more has to be masked around it, and more surface has to be blended afterward for the repair to disappear.
05Does the estimate include tax?
Yes, on the taxable portion. Sales tax at 7.75 percent applies to parts and materials. Labor is not taxed in California. On a refinish heavy job the materials line is a real share of the total, which is why the calculator computes it separately rather than folding it into an hourly figure.
