Plan the work
Carry the estimate into the job plan.
The useful result is not just the number. It should support owners, programme assumptions and delivery readiness.

Estimate To Evidence
Make the result useful beyond the screen.
A calculator result is most useful when it feeds the job plan, material checks and team briefing that follow the estimate.
Measure the work
Use the estimate as a planning input for scope, labour, equipment and site readiness.
Plan materials
Turn quantities into stock checks, purchasing notes and job-linked material records.
Brief delivery
Give teams the assumptions, limits and checks behind the number before work starts.
Explanation
What this calculates
Use this for early cable ordering checks, then verify against drawings, containment routes, voltage drop checks and installation design.
Formula
Cable length = measured run x repeated runs x (1 + waste %)
Inputs are validated on screen and converted where unit options are available.
Worked Example
Example result
A 120 m measured run with one cable route and 10% waste gives 132 m of cable.

Related FAQs
Can this calculate any material?
Yes for simple area-based rates such as tiles, boards, membranes or rolls.
From Material Quantity Calculator
Should I round to pack sizes?
Yes. Round final ordering quantities to supplier packs, pallets or roll sizes.
From Material Quantity Calculator
Does this include mortar?
No. Estimate mortar separately using supplier rates or your estimator's norms.
From Block Calculator
Should I include waste?
Yes. Cutting, breakage and site handling usually need an allowance.
From Block Calculator
FAQ
Calculator questions.
Does this size the cable?
No. It estimates length only. Cable sizing and protection must be designed by a competent electrical person.
Can I use it for multiple circuits?
Yes, if the repeated-runs input reflects the number of equivalent cable runs being ordered.
