Every estimate breaks into four sections: parts, labor, paint and materials, and sublet. Check two things first, the part-type codes (OEM vs. A/M vs. LKQ) and whether teardown, blend, and ADAS calibration lines actually appear. A missing line today is a surprise bill later.

The Anatomy of a Standard Estimate
Most California shops use one of three estimating systems:
- CCC One (most common, used by most insurers)
- Mitchell
- Audatex
All three produce similar-looking estimates. Here’s the structure:
Header
- Customer name, vehicle info (year, make, model, VIN)
- Insurance company and claim number (if applicable)
- Estimate date
- Estimator name
Damage Description
A narrative description of damage and proposed repair plan. Read this carefully, it should match what you actually see on the car.
Line Items
The bulk of the estimate. Each repair operation is itemized. Here’s what each column actually means:
- Operation. What's being done, R&R, Repair, Refinish, and so on.
- Part Description. Which part the line refers to.
- Part Number. The OEM part number, when one applies.
- Hours. Labor time in decimal hours, for example 1.2 hours.
- Part Price. What the shop is charging for that part.
- Paint / Material. The paint and materials cost tied to that line.
- Sublet. Work done by third parties, alignment, ADAS calibration.
- Tax. Sales tax on parts and, depending on the state, materials.
Common Acronyms
- R&R = Remove and Replace (replace with new part)
- R&I = Remove and Install (remove temporarily then reinstall, common for accessing damaged areas)
- Repair = Fix existing damage on the part
- Refinish = Paint refinish on the part
- Blend = Paint a small section of an adjacent panel to invisibly transition new paint to old
- OEM = Original Equipment Manufacturer parts (factory)
- A/M = Aftermarket parts (third-party)
- LKQ = Like Kind and Quality (used OEM, from a wrecked vehicle)
- Recond = Reconditioned part
- Sublet = Work done by a third-party vendor (alignment shop, ADAS calibration, glass)
- P&M or Paint/Mat = Paint and Materials cost
- PDR = Paintless Dent Repair
Reading the Labor Section
Labor hours are calculated from a “P-pages” book (Mitchell’s terminology) that gives standard labor times for every operation on every vehicle. These are pulled from manufacturer data and reflect what an experienced technician should be able to complete each operation in.
Examples:
- Front bumper cover R&R: typically 0.7–1.5 hours
- Door R&R: typically 1.5–3.5 hours
- Hood R&R: typically 0.6–1.2 hours
- Frame straightening: typically 4–20+ hours depending on damage
Multiply hours by the shop’s hourly rate ($90–125 in California in 2026) to get the labor charge for that operation.
Reading the Parts Section
Look for:
- Part description, should be specific (not “bumper” but “front bumper cover, primed, OEM”)
- OEM vs aftermarket, labeled in the description
- Part numbers, actual manufacturer part numbers verify OEM parts
- Price, should be in range (we’ll cover this below)
If a critical part (airbag, structural component, ADAS sensor) shows as aftermarket or LKQ, question it.
Reading the Paint Section
Paint operations break down into:
Refinish Labor
The labor time to prepare and paint the panel. Standard labor time depends on panel size and complexity. A full hood refinish is typically 3.5–5 hours of refinish labor.
Blend Labor
When new paint is applied to a panel adjacent to a damaged area, the painter “blends”, sprays new paint partway across the adjacent panel and fades into the original, to make the color transition invisible. Blend labor is usually 50% of the panel’s refinish hours.
Paint and Materials (P&M)
A separate line for the actual materials consumed, paint, clear coat, primer, masking, abrasives. Often expressed as a per-panel charge or a percentage of refinish labor.
In California, P&M typically runs $45–95 per refinish hour. So a panel with 4 hours of refinish labor might have $200–400 of P&M.
What to Question
Aftermarket Parts on Safety / Structural Components
Push back on aftermarket airbags, structural reinforcements, bumper absorbers, ADAS-adjacent parts. Demand OEM.
Missing ADAS Calibration
If your vehicle has lane-keep, adaptive cruise, blind-spot, or 360 cameras, there should be a sublet line for ADAS calibration. If it’s missing, the shop or insurer is cutting a corner. Add it.
Unusually Low Labor Hours
If a major operation has fewer hours than industry standard, the shop may be cutting time to win the work, at the cost of quality. Compare 2–3 estimates if you can.
Missing Operations
Standard operations that should appear on most repairs:
- Vehicle wash at completion
- Test drive for collision repairs
- Alignment check after structural work
- Cover car during paint (to protect interior)
- Mask body before paint
If these are missing, the shop is cutting corners or charging them under other line items.
”Negotiated” Discount Lines
Sometimes insurers negotiate discounts on labor or P&M. These show as negative lines. As long as the underlying scope is correct, the discount itself isn’t a problem, but watch that the scope doesn’t get cut to “earn” the discount.
In short, the red flags to watch for:
- Aftermarket airbags or structural parts on a car that should be OEM
- No ADAS calibration line on a vehicle with sensors
- Labor hours noticeably under industry standard
- Missing wash, test drive, or alignment check line items
- A total that’s oddly lower than every other estimate you got
How to Compare Two Estimates
When you have estimates from two shops, compare line-by-line:
- Same scope of operations? Both shops should propose the same R&R, repair, refinish, and blend lines.
- Same parts spec? Both OEM or both aftermarket? If different, ask why.
- Same labor hours? Standard hours should be identical, they come from the same P-pages. Differences here usually indicate a less-thorough estimate.
- Same P&M rate? Wide variation is unusual.
Cheaper isn’t always better. A 25% cheaper estimate that skips ADAS calibration or specifies aftermarket airbags isn’t a deal, it’s a different (and worse) repair.
When the Estimate Will Change (“Supplements”)
Initial estimates are best guesses based on what’s visible. After teardown, additional damage almost always appears:
- Bent inner fender
- Cracked airbag sensors
- Damaged HVAC condenser
- Internal damage to bumper assemblies
Your shop submits a supplement to the insurer with photos and documentation. The carrier authorizes additional work. You don’t pay more out of pocket, supplements are part of the same claim.
A supplement of 15–40% above the initial estimate is normal on moderate-to-heavy damage.
The TL;DR
A good body shop estimate is:
- Itemized, every operation, every part, every labor hour
- OEM by default for safety and structural parts
- Includes ADAS calibration if your vehicle has ADAS
- Realistic labor hours matching industry standards
- Includes paint blending for adjacent panels
If your estimate is missing any of these, ask why. Get a transparent, itemized estimate from us, we’ll walk you through every line.
