This tool is for guidance only. Final screed quantities vary with levels, falls, substrate condition, mix type, reinforcement, and project-specific conditions.
What This Tool Helps With
Useful for quick floor build-up and material checks.
- Sense-check floor screed volume before placing orders.
- Compare thickness options against early material cost.
- Allow for practical waste and placement tolerance.
- Export a branded summary for internal reference or client discussion.
Important Note
This is a planning tool, not a floor level survey.
Screed quantities still depend on level variation, falls, bay layout, substrate condition, specification, and installation method. Use the calculator as a first pass before ordering from live project information.

Quick answers about the screed calculator.
What does the screed calculator estimate?
The calculator estimates floor screed volume, waste allowance, and approximate cost from floor area, screed thickness, and a rate per cubic metre.
Why is screed thickness entered in millimetres?
Screed is commonly specified in millimetres, so the calculator uses thickness in millimetres and converts it automatically into volume.
Should I allow waste on screed quantities?
Usually, yes. Waste allowance helps account for variation in levels, uneven substrate, spillage, and practical placement tolerance.
Is this suitable for final ordering?
It is best used for early planning only. Final screed quantities should be checked against levels, falls, substrate condition, specification, and the chosen installation route.
Next Step
Need a formal estimate beyond a quick screed quantity check?
Use the calculator as a starting point, then get in touch if you need project-specific estimating support, take-off, or quantity review on live construction work.
