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.

The calculator also shows equivalent markup so commercial teams can compare both measures.
Formula
Inputs are validated on screen and converted where unit options are available.
Worked Example
GBP1,250 revenue and GBP1,000 cost gives GBP250 profit, 20% margin and 25% markup.
