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
The calculator multiplies total labour hours by hourly rate and adds a burden allowance.
Formula
Cost = workers x hours x days x rate x (1 + on-cost %)
Inputs are validated on screen and converted where unit options are available.
Worked Example
Example result
5 workers x 8 hours x 10 days x GBP35/hour with 20% on-costs equals GBP16,800.
