Electrical
Electrical Route Efficiency Calculator
Estimate the billable-time opportunity associated with an electrical service route, using your own before-and-after hours.
Result
Not all unbilled time is waste. Travel, restocking, training and warranty calls are necessary and will never be zero. The useful question is whether the share is drifting, not whether it reaches 100%.

- Compare days with similar job types and starting locations.
- Include paid travel and parts-collection time in the capacity being reviewed.
- Use a realistic change in billed hours rather than treating all driving time as removable.
Where this one goes wrong
This is a time-utilization worksheet. It has no address, mileage or routing engine and cannot calculate the shortest route. Geographic clustering must also respect appointment promises, technician skills and whether the required parts are on the van.
Questions
About this calculator
How do I test a revised service area?
Measure or estimate the billed hours possible under each schedule, then run both cases. Keep headcount, rates and the observation period consistent.
Does fewer miles necessarily mean more revenue?
No. The saved time must fit useful work that customers actually want. A short gap between appointments may not accommodate another electrical visit.
Are vehicle savings included?
Not separately. Fuel, mileage and vehicle wear need their own calculation; the outputs here value time at the wage and selling rates entered.
The formula
utilisation = billed hours / paid hours

How to use this calculator
- Paid hours per day. Enter your own figure; the page starts at 8.
- Hours that reach an invoice. Enter your own figure; the page starts at 5.2.
- Number of technicians. Enter your own figure; the page starts at 3.
- Rate charged per hour ($). Enter your own figure; the page starts at $130.
- Cost per paid hour ($). Wage plus burden.
- Working days per month. Enter your own figure; the page starts at 22.
The result updates as you type, so you can try a figure, see what it does to billable share of the day, and change it back. Nothing you enter is sent anywhere or saved.
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 |
|---|---|
| Paid hours per day | 8 |
| Hours that reach an invoice | 5.2 |
| Number of technicians | 3 |
| Rate charged per hour | $130 |
| Cost per paid hour | $34 |
| Working days per month | 22 |
What comes out
| Result | Value |
|---|---|
| Billable share of the day main result | 65.0% |
| Unbilled hours per month | 185 |
| Revenue those hours would have carried | $24,024 |
| What the unbilled hours cost in wages | $6,283 |
65.0% of the paid day reaches an invoice. The rest is 185 hours a month, costing $6,283 in wages and carrying $24,024 of revenue that never happened.
How sensitive the answer is
Holding everything else steady and changing only rate charged per hour, this is what happens to billable share of the day. It is worth knowing which of your inputs the answer actually hinges on, and which barely move it.
| Rate charged per hour ($) | Billable share of the day |
|---|---|
| $65 | 65.0% |
| $98 | 65.0% |
| $130 example above | 65.0% |
| $195 | 65.0% |
| $260 | 65.0% |
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
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.
