Estimate repair sales and gross contribution from completed electrical faults and remedial jobs.
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.

- Completed repairs are a different count from diagnostic attendances.
- Average invoice should reflect the mix of minor fixes and longer fault resolution.
- Margin depends on the travel, labour and parts attached to those repairs.
Where this one goes wrong
A return visit under warranty can consume repair capacity without creating a new sale. Keep it out of billable job volume while including the associated cost, otherwise both revenue and margin look stronger than the work supports.
Questions
About this calculator
Should an unsuccessful diagnosis count as a repair?
Only if your defined work stream includes that billable diagnostic service. Separate it when comparing actual repaired jobs so the average value remains meaningful.
Can emergency and planned repairs share an average?
They can, but the blend hides attendance and scheduling differences. Model them separately when deciding opening hours or staffing cover.
Does the annual gross-profit result cover the office?
It applies the entered gross margin to projected repair sales. Overhead, collection timing and any costs outside that margin still need to be considered.
The formula
revenue = jobs x average value; gross profit = revenue x margin

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