The Estimating Grind Nobody Talks About
Ask any estimator what they spend most of their time on, and the answer is usually some version of the same thing: reviewing damage, going through photos, building the estimate line by line, and then going back through everything again because something was missed.
This is considered normal. It's just the job. But "normal" doesn't mean "efficient," and it definitely doesn't mean "free."
The estimating process is where a significant amount of your shop's operating cost lives - not in parts, not in paint, not in labor on the floor, but in the people-hours required to turn a car full of damage photos into an accurate estimate. Most shop owners have a general sense of this. Very few have looked at the specific numbers.
Breaking Down a Typical Estimate
Let's walk through what a moderately complex claim actually involves on the documentation side.
A routine fender bender might generate 30 to 50 photos. A moderate collision - door, quarter panel, maybe some frame work - typically runs 80 to 120 photos. A significant structural repair or a total-loss-adjacent vehicle can easily reach 200 or more.
For this analysis, let's use a realistic mid-range: 100 photos on a moderately complex estimate. Here's what goes into reviewing that set:
- Opening and loading the photo set
- Working through each image - identifying damage type, severity, and location
- Cross-referencing what the photo shows against what's already on the estimate
- Flagging items that need a closer look or a second opinion
- Going back through missed items and adding them in
- Documenting the damage narrative for the supplement file
A skilled, experienced estimator moving at a focused pace can review a photo and make a judgment call in about 20 to 30 seconds. But they're also context-switching - answering questions from the floor, taking calls, handling the desk. In real shop conditions, a thorough review of 100 photos takes 45 to 75 minutes including basic documentation. Call it an hour as a working estimate.
What One Hour Actually Costs
A competent estimator - someone with the skill and experience to write accurate estimates and handle supplements - costs a shop somewhere between $55,000 and $75,000 per year in salary. Add benefits, employer taxes, and the overhead of their workspace and tools, and you're looking at a fully-loaded cost of $35 to $50 per hour. Let's use $42 as a middle-of-the-road number.
One hour of estimator time = $42.
That's what the photo review portion of a single moderate estimate costs you, before the actual estimate is written, before any supplements are handled, before any customer communication happens.
| Scenario | Cost per Estimate | Weekly (15 estimates) | Annual |
|---|---|---|---|
| Conservative (45 min / 100 photos) | $31.50 | $472 | $24,570 |
| Moderate (60 min / 100 photos) | $42.00 | $630 | $32,760 |
| Complex (90 min / 150 photos) | $63.00 | $945 | $49,140 |
| Blended average (15 estimates/week) | ~$45 | ~$675 | ~$35,100 |
That's thirty-five thousand dollars a year in estimator time spent just on photo review - not estimate writing, not supplement management, not customer communication. Just reviewing the photos.
For many shops, that number is higher. A busy 20-estimate-per-week operation with a lot of structural work is looking at $40,000 to $50,000 in annual photo review labor cost.
The Costs You Can't See on the Timesheet
The direct labor cost is the easy part to calculate. There are three other cost categories that are harder to quantify but equally real.
Missed Damage
Even skilled estimators miss things when they're rushed, tired, or working through their fifth estimate of the day. Manual photo review is a human process, and human processes have human error rates.
When damage is missed in the initial estimate, it shows up as a supplement - which is recoverable - or it shows up as unbillable time on the floor when the tech finds it mid-repair and the car is already disassembled. The second scenario is the expensive one. You've committed the labor before you've been approved to bill for it. Getting paid becomes a fight instead of a process.
Industry estimates on supplement rates vary, but figures of 30 to 50 percent - meaning nearly half of all claims result in at least one supplement - are commonly cited among shops that track this data. Some portion of those supplements exist because something was missed at the estimate stage.
Re-Work and Production Disruption
A supplement identified before a car enters production costs you paperwork time and a few days of wait. A supplement discovered after the car is partially disassembled costs you re-scheduling, idle bay time, technician disruption, and customer communication about a delayed completion date. The shop that catches the problem early wins every time - and catching it early starts with a more complete initial estimate.
Estimator Capacity
An estimator who spends 45 to 90 minutes per estimate on photo review can only write so many estimates per day. If that time were meaningfully reduced, the same person could handle more volume, spend more time on supplements, or focus on higher-value activities like customer communication and production coordination. This isn't about cutting headcount - it's about what your best people are actually doing with their hours.
Why Shops Accept This as Normal
Part of the answer is that this cost is invisible. It never shows up as a line item. No invoice says "manual photo review: $35,100." It's absorbed into the estimator's salary, which is already a fixed cost in the owner's mind.
The other part is that there hasn't always been a better option. This is how estimating has worked. You get the photos, you go through them, you build the estimate. That's the job.
The question isn't whether this cost is real - it is. The question is whether you want to keep accepting it as fixed, or whether you want to know what better actually looks like for your shop's specific volume and workflow.
What to Look At in Your Own Shop
You don't need sophisticated software to start understanding your own numbers. Here's a simple audit you can do in a week:
- Track time on 10 estimates. Have your estimator log actual time spent on photo review separately from time spent writing the estimate. Even a rough log tells you more than a guess.
- Count your weekly estimate volume and average photo count per claim. Your insurer portals or estimating system probably have this data already.
- Calculate your annual photo review cost using the framework above. Use your estimator's actual fully-loaded hourly rate if you know it.
- Check your supplement rate. If you're not tracking what percentage of estimates result in supplements, start. That number is a proxy for estimate completeness.
Once you have those numbers, you know your baseline. You know what the problem actually costs - not in a general sense, but in dollars, at your shop, per year.
That's the starting point for any decision about whether and how to improve it.
