Electrical
Electrical Maintenance Revenue Calculator
Project a maintenance work stream from completed visits and invoice value, keeping scheduled tasks separate from repair sales.
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.

- Count billable maintenance visits rather than every customer interaction.
- Average value should match the inspection or servicing scope being offered.
- Gross margin must allow for travel, reporting and the direct delivery effort.
Where this one goes wrong
A scheduled inspection can generate a separate remedial quotation, but that work is not maintenance revenue until it is authorized and delivered. Mixing both obscures whether the original maintenance service can support its own cost.
Questions
About this calculator
Can I use this for prepaid agreements?
Use a consistent revenue allocation to the visits, or use the agreement calculator for annual fees and obligations. Counting the full fee and its included visits again duplicates revenue.
How should seasonal maintenance rounds be modeled?
Run representative busy and quiet periods separately. Multiplying a concentrated inspection month by twelve can overstate the annual workload.
What does the business-share input add?
It estimates company revenue implied by the maintenance stream's assumed share. It does not forecast demand for other electrical work or verify the available staffing.
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 |
|---|---|
| Maintenance jobs per month | 28 |
| Average value | $540 |
| Gross margin on this work | 47% |
| Share of total revenue | 40% |
What comes out

How sensitive the answer is
Holding everything else steady and changing only average value, this is what happens to maintenance revenue per month. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Average value ($) | Maintenance 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.
Estimating is the easy part
