Shop profit calculator

Three places shops lose money without noticing: declined work nobody follows up, estimates that sit unapproved, and advisor hours lost to phone tag. Put in your own numbers and see what fixing them is worth, after the cost of the software.

Declined work you win back
Assumption: the dollar value of work customers said no to last month. Your estimates or ROs show it; if you don't track it, start with a guess.
Assumption: how much of that work comes back when someone texts a reminder. Start low; you can test it for a month.
Assumption: what you keep after parts and tech pay, as a share of the sale. Your P&L or shop reports show it.
More estimates approved
Assumption: estimates you present to customers in a typical month.
Assumption: how many percentage points your approval rate goes up with photos and text approval, e.g. 60% to 65% is 5 points.
Assumption: average gross profit on one approved job, not the sale price.
Service advisor time
Assumption: time no longer spent on phone tag, retyping and looking things up.
Assumption: days the shop is open in a month.
Assumption: wage plus payroll costs for one hour of advisor time.
Follow-up texts and text approval come with every plan; AI estimate drafts and inspection write-ups are on AI and Growth.

If it only works half as well: $298.08 a month.

Advisor time is 8.7 hours a month. It only turns into money if those hours go to selling and follow-ups, or replace hours you would otherwise pay for.

Results are estimates based on the assumptions you enter, not a guarantee of results. They are for general information only and are not financial, accounting or other professional advice. Your shop’s results will differ.

How it works

Each line is one assumption times another. Nothing is hidden:

  • Deferred work recovered = declined work × share won back × gross margin
  • Extra approvals = estimates × extra approval points × gross profit per job
  • Advisor time = minutes saved per day × working days ÷ 60 × cost per hour
  • Net = the three added up, minus the plan price. Yearly = net × 12.

Example with the defaults: $3,900 × 15% × 50% = $292.50 recovered. 60 × 5% × $195 = $585.00 from approvals. 20 minutes × 26 days is 8.7 hours, × $25 = $216.67. That’s $1,094.17 gross, $845.17 a month after the $249 AI plan, or $10,142.00 a year.

Questions shops ask

Where do the default numbers come from?

They're a worked example for a small shop, not an industry average: $3,900 of declined work a month, 60 estimates, and an advisor at $25 an hour. Replace each one with your own numbers; the result is only as good as what you put in.

How do I find my declined work?

Add up the lines customers said no to on last month's estimates. If your system doesn't track declined lines, go through a week of estimates by hand and multiply by four.

Why does it use margin, not sales?

Because a $1,000 job doesn't put $1,000 in your pocket. Parts and tech pay come out first. Using gross margin keeps the estimate closer to the money you actually keep.

Is saved advisor time really money?

Only if it's used. If your advisor spends the saved hours following up on declined work and selling, or you avoid hiring help, it's real. If not, set the minutes to zero and see if the rest still pays.

What does the 'half as good' line mean?

It halves the gross result and subtracts the full plan price. If that's still positive, the decision doesn't depend on every assumption being right.

Which plan should I pick?

Core has text approval and follow-up campaigns. AI adds AI estimate drafts, inspection write-ups and labor lookup. Growth adds a shop website and online booking. Prices are per location, per month.

What happens to my email if I ask for the report?
