Lookup time is the easiest shop cost to ignore, because it never appears as a line item. Nobody writes “14 minutes finding the torque spec” on a repair order. It shows up instead as a bay that turned three jobs instead of four, or a tech who stayed late to finish one. This page gives you the arithmetic to size it for your own shop, field by field, with every default treated as a starting guess rather than a measurement.
Quick Answer: Non-billable lookup cost per month = technicians × lookups per tech per day × avoidable minutes per lookup × workdays per month ÷ 60 × your labor rate. Avoidable minutes means the time spent finding the right page — menu paths, wrong engine selections, walking to a terminal — not the time spent reading it. Two conditions decide whether the result is real money: recovered time only becomes revenue if another repair order is waiting, and the inputs have to be yours. Every default on this page is your estimate — adjust to your shop. For reference points, Tekmetric’s index puts the U.S. average labor rate at $132/hour, and PartsTech’s 2025 report found almost half of shops between $120 and $159. The output is a planning figure, not a promise, and the fastest way to improve it is one week of actual lookup counts.
The Four Inputs, and How to Fill Them
1. Technicians who do their own lookups
Count the people who stop work to find information, not headcount. A service advisor who checks a labor time belongs in the count; a lot porter doesn’t. If your lead tech answers everyone else’s questions, count them once here and note it — their interruptions get handled separately below.
2. Lookups per tech per day
Your estimate — adjust to your shop. Count every spec, procedure, diagram, bulletin, DTC definition, and labor time check, including the ones that take seconds. Most shops guess low before they count, because short lookups don’t register as events. A tally sheet at the bay for one week replaces the guess.
3. Avoidable minutes per lookup
Your estimate — adjust to your shop. This is the single input that moves the result most, and the one people get wrong by including reading time. Split the lookup in two: find-time is everything until the right page is open; read-time is using it. Only find-time belongs here, because only find-time is recoverable.
4. Your door labor rate
Use your posted rate, not an average. If you want reference points: Tekmetric’s labor rate index, built on data from more than 10,000 shops, puts the U.S. average at $132 per hour, PartsTech’s 2025 survey found almost half of shops charging $120–$159, and the Automotive Management Network tracker summarized by MOTOR shows state averages ranging from about $110 in Mississippi to $176 in California.
The Worksheet
Fill the middle column with your numbers. The example column is illustrative only — these are estimates, not measured figures from any shop.
| Input | Your shop | Example (estimate) |
|---|---|---|
| A. Technicians doing lookups | 4 | |
| B. Lookups per tech per day | 6 | |
| C. Avoidable minutes per lookup (find-time) | 3 | |
| D. Workdays per month | 21.7 | |
| E. Labor rate per hour | $132 | |
| Hours per month = A × B × C × D ÷ 60 | 26.0 | |
| Capacity value = hours × E | $3,432 | |
| F. Share that would convert to billed work | 50% | |
| Adjusted monthly value | $1,716 |
Run the same arithmetic at two other values of C — one minute and five minutes — before you trust the middle one. At the example shop, that spread runs from about $1,140 to $5,720 a month in capacity before any conversion adjustment, which tells you how much the whole exercise depends on an input most owners have never measured.
Why Line F Exists
A recovered minute is not automatically worth your door rate. What it’s worth depends on what happens next:
- Another repair order is waiting. The time gets billed, and the full rate applies.
- The work would otherwise have run into overtime. It’s worth the overtime wage instead. At the May 2025 BLS median technician wage of $24.34/hour, time-and-a-half is about $36.51.
- Bays are slow. The tech waits either way, and the direct value is close to zero.
Most shops are in the first row some weeks and the third row others. Setting F at 100% produces a number nobody will believe at the next staff meeting; setting it honestly produces one you can defend.
What the Calculator Leaves Out
Three costs sit outside the arithmetic, and all three are real:
- Interrupted lead techs. When a junior tech asks where to find something, two people stop. A 4-minute question costs 8 tech-minutes, and one of them belongs to your most productive person.
- Comebacks from the wrong information. A spec for the wrong engine, or a bulletin that has since been superseded, produces rework the calculator never sees. If you want a rough placeholder, price one 2-hour redo at your labor rate.
- Jobs quoted from memory. When looking something up is slow, estimates get written from recall. That lands on the estimate, not the clock, which is why OEM labor times belong in the quote rather than a remembered figure.
Getting Better Inputs in One Week
Every number above improves with one week of counting. Put a tally sheet at each bay and record, for every lookup: what was needed, where the tech went for it, minutes until the right page was open, minutes spent reading it, and whether the first answer turned out to be for the wrong vehicle. On Friday, average lines B and C from the sheet and rerun the worksheet.
Two patterns usually show up in the totals. A few lookup types account for most of the find-time, and the “asked another tech” column is larger than anyone expects. That is the same ground covered in where technicians’ lookup time actually goes and the hidden cost of searching before every repair order, now with your shop’s numbers instead of someone else’s.
What to Do With the Number
Compare it against what a fix would cost, using the same arithmetic in reverse. At $132/hour, Jayda’s Business plan at $149/month equals about 68 billed minutes a month across the whole shop, roughly three minutes per workday; Pro Tech at $14.95/month equals about 7 billed minutes. Those are break-even thresholds, not savings claims — Jayda doesn’t publish a minutes-saved figure, and you shouldn’t accept one from any vendor without testing it.
The honest test is to rerun your tally week while using a different lookup method and compare find-time per lookup. Business runs on a 12-month agreement at $149/month for up to 10 techs, and its 7-day trial is activated through the Jayda team rather than self-serve signup, so plan the trial week around real repair orders. What you’re measuring is whether the documents arrive faster and still show the OEM source behind them, since a faster wrong answer is worth less than a slow right one — the reason Jayda retrieves manufacturer documents rather than generating answers about them, and never writes a procedure when a document is missing.
If the trial doesn’t move line C, you’ve still gained something: a measured baseline for lookup cost, and a number you can put in front of the team. For the broader buying criteria beyond time, including data licensing and coverage, see how to choose OEM repair software.
