HVAC Revenue Calculator
Project revenue from job volume, average ticket and the mix between service and installation.
Result
Revenue is not profit. This is the top line before the cost of doing the work and before overhead, and it excludes sales tax, which is collected for the state rather than earned.

- Capacity, since revenue is capped by technician hours available.
- Average ticket, which moves with mix and with inspection discipline.
- Close rate on quoted work.
Where this one goes wrong
Forecasting growth as more calls. Most companies have more approvable work already in front of them than capacity to deliver, and raising close rate is cheaper than buying more leads.
Questions
About this calculator
What raises revenue fastest?
Usually close rate and average ticket rather than call volume, because the acquisition cost is already spent on work you have already been asked to quote.
How do I model capacity?
In technician hours available per month, not in jobs. Job counts hide the difference between a service call and a changeout.
Should maintenance revenue be modelled separately?
Yes. It is predictable and schedulable, which makes it different in kind from demand-driven service and installation work.
The formula
monthly revenue = jobs x average value, compounded by the growth rate across twelve months

How to use this calculator
- Jobs per month. Enter your own figure; the page starts at 78.
- Average job value ($). Enter your own figure; the page starts at $620.
- Monthly growth (%). Enter your own figure; the page starts at 0%.
- Share actually collected (%). Write-offs, disputes and the invoices nobody ever pays.

A worked example
These are the figures the calculator opens with. Every number in the results column below is produced by the same calculation the page runs, so you can follow it through before putting your own figures in.
What goes in
| Input | Value |
|---|---|
| Jobs per month | 78 |
| Average job value | $620 |
| Monthly growth | 0% |
| Share actually collected | 97% |
What comes out
| Result | Value |
|---|---|
| Revenue this month main result | $48,360 |
| Revenue over twelve months | $580,320 |
| Collected over twelve months | $562,910 |
| Never collected | $17,410 |
$48,360 a month and $580,320 over a year, of which $562,910 actually reaches the bank.
How sensitive the answer is
Holding everything else steady and changing only average job value, this is what happens to revenue this month. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Average job value ($) | Revenue this month |
|---|---|
| $310 | $24,180 |
| $465 | $36,270 |
| $620 example above | $48,360 |
| $930 | $72,540 |
| $1,240 | $96,720 |
Every other input is held at the example value while this one changes, which is not how a real job behaves. Treat it as a guide to which number matters most, not as five separate quotes.

Before you rely on this number
Sizing, capacity and load figures here are planning estimates. A real installation depends on the manufacturer's data for the specific equipment, the duct system it is going into, and a proper load calculation for the building. Use this to sanity-check a number or price a job, not to select equipment.
Estimating is the easy part
The jobs you never hear about cost more than the ones you mis-measure. BDEVY builds the marketing, systems and automation that bring them in.
