The short version
An electrical estimate has to separate the price of the visible work from whatever the existing wiring forces on the job. A good electrical estimate separates the lines you are sure of from the ones that depend on what you find, and gives the client a range.

The estimate below is for tracing a tripping circuit, where the cause may be a single device or something in the panel. Each line is either firm or an allowance with a range of quantities. The rates are examples from the starter lines in the cost estimator, not market prices, so replace them with your own.
| Line item | Unit | Qty or range | Example rate | Basis |
|---|---|---|---|---|
| Diagnostic and service call fee | job | 1 | $110.00 | Firm |
| Testing and inspection sign-off | job | 1 | $120.00 | Firm |
| Electrical panel replacementAllowance: only if the panel proves to be the fault. | job | 0 to 1 | $650.00 | Allowance |
| Socket or switch installationAllowance: devices replaced depend on what fails testing. | each | 1 to 4 | $55.00 | Allowance |
| LaborAllowance: labor depends on how many circuits are affected. | hour | 2 to 6 | $60.00 | Allowance |
Worked estimate range
Adding the firm lines to the allowances at their smallest and largest quantities gives a low end and a high end. The tax rate is an example only, so use your own and your local treatment.
| Estimate range | Low end | High end |
|---|---|---|
| Firm lines | $230.00 | $230.00 |
| Allowances (minimum and maximum quantities) | $175.00 | $1,230.00 |
| Subtotal | $405.00 | $1,460.00 |
| Sales tax at an example rate of 8% | $32.40 | $116.80 |
| Estimated total | $437.40 | $1,576.80 |
This is not a fixed price. It is a range the client can plan around until the unknowns are resolved.
Assumptions behind an electrical estimate
- Starting point. The range assumes the fault is at a device or a single circuit. A panel fault is shown only as an allowance.
- Existing wiring. It assumes the wiring behind the fault is sound. Unsafe findings are reported and priced separately.
- Access. It assumes the panel and the affected walls are reachable without major opening up.
What can change the price
Write these on the estimate so a revised figure is never a surprise:
- A panel found to be the cause.
- Wiring that no longer meets current requirements.
- More affected circuits than first reported.
When to send a quote instead
An electrician gives an estimate before opening a panel or tracing a fault, and a quote when the circuits and devices are counted and agreed. Once the scope is fixed, move to the electrical quote template, which adds a fixed scope, exclusions, a payment schedule and a place to sign.
