Electrical
Electrical Installation Revenue Calculator
Model installation revenue from completed electrical projects and their average value before checking backlog and crew capacity.
Result
Service lines rarely carry the same margin. Splitting them is the only way to see which part of the business is paying for the rest, which is frequently not the part that looks busiest.

- Use completed projects rather than the number of progress invoices.
- The average contract value should match the project type being forecast.
- Direct margin must include purchased equipment and any subcontracted delivery.
Where this one goes wrong
A signed backlog is not necessarily revenue deliverable this month. Utility coordination, customer readiness and inspection milestones can delay completion. Reconcile the projected project count with the crew time and handover conditions each project requires.
Questions
About this calculator
Should progress payments count as separate jobs?
No. They are billing events within a project. Counting each payment while using the full contract value as the average would multiply the same installation several times.
Can a panel replacement and a full rewire share one average?
Only if the mix is stable and documented. Separate runs expose their different values, duration and delivery costs more clearly.
What limits the usefulness of annualized revenue?
It assumes the entered monthly completion pattern continues. Backlog quality, available electricians and equipment lead times determine whether that pattern is achievable.
The formula
revenue = jobs x average value; gross profit = revenue x margin

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 |
|---|---|
| Installation jobs per month | 28 |
| Average value | $540 |
| Gross margin on this work | 47% |
| Share of total revenue | 40% |
What comes out
| Result | Value |
|---|---|
| Installation revenue per month main result | $15,120 |
| Per year | $181,440 |
| Gross profit per year | $85,277 |
| Implied total business revenue | $453,600 |
The installation line brings in $181,440 a year and earns $85,277 of gross profit on it.
How sensitive the answer is
Holding everything else steady and changing only average value, this is what happens to installation revenue per month. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Average value ($) | Installation revenue per month |
|---|---|
| $270 | $7,560 |
| $405 | $11,340 |
| $540 example above | $15,120 |
| $810 | $22,680 |
| $1,080 | $30,240 |
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
Conductor sizing, voltage drop and load figures are governed by code, and the code takes precedence over any calculator. Ambient temperature, conduit fill, continuous load factors and the specific installation all change the answer. Treat this as a first pass, not a design.
