Electrical Cost Estimate Chart
Use this worksheet after the calculator result to record labor, material, equipment, overhead, markup, contingency, exclusions, and quote review.
Quick reference table
An electrical cost estimate chart is a calculator-led planning worksheet. It turns the estimate result into line items that can be checked before sending a quote or project budget.
Electrical cost estimate worksheet
| Item | Record from calculator | Follow-up |
|---|---|---|
| Labor | Hours, rate, crew, overtime note | Validate production assumptions |
| Material | Major material and quote basis | Update vendor pricing before issue |
| Overhead and markup | Overhead, markup, margin | Confirm business pricing policy |
| Scope | Exclusions, alternates, contingency | Align with customer and contract notes |
Estimate takeoff review lanes
| Estimate lane | Record on worksheet | Why it affects price |
|---|---|---|
| Labor production | Crew size, hours, access, overtime | Field conditions can dominate the estimate |
| Material takeoff | Panel, wire, conduit, devices, vendor quote date | Material pricing changes quickly and needs a source date |
| Permit and utility | Permit allowance, utility coordination, inspection note | External requirements can add cost and schedule risk |
| Contingency and exclusions | Unknowns, excluded work, alternates | Scope clarity prevents the calculator total from becoming an accidental contract |
How to use this chart
Start with scope
Write the included work, exclusions, site assumptions, and schedule before reading the price.
Separate cost layers
Keep labor, material, equipment, overhead, markup, and contingency in separate rows.
Route quote review
Use the worksheet to assign vendor updates, scope checks, and final pricing approval.
Formula basis
Estimated price = direct cost + overhead + markup + contingency.
- Direct cost includes labor, material, equipment, permits, and subcontractor inputs.
- Overhead is the project or business cost allocation entered in the calculator.
- Markup is the planned profit or pricing adjustment.
- Contingency is a separate allowance for uncertainty, not a hidden guarantee.
Worked examples

Tenant build-out estimate record
Keep takeoff quantities, crew hours, fixture package, permit allowance, shutdown window, contingency, exclusions, and quote expiration together before pricing approval.
