The flooring calculator takes cost of material per unit area, room length, waste factor and room width and returns total material area required, total material cost and room area. It is built for quick answers, for checking somebody else’s arithmetic, and for the moments when a formula book is not within reach.
What Is the Flooring Calculator?
The flooring calculator turns cost of material per unit area, room length, waste factor and room width into total material area required, total material cost and room area, so you can order the right amount of material the first time.
Material estimates are where projects go over budget. Getting the quantities right before the delivery arrives is worth more than any discount on the order.
How to Measure for the Flooring
Measure everything in the same unit and take the largest dimension you can reasonably use rather than the average. Formwork, ground conditions and cutting waste all push the real figure above the theoretical one.
Where a plan calls for a specific thickness, check it against local building regulations before you order. The calculator reflects the relationship, not the code.
Allowing for Waste and Errors
Order a little more than the calculation suggests. The gap between the theoretical quantity and what actually arrives on site is normally waste, spillage, over-excavation and uneven grading, and all of it comes out of the same budget.
Write the figures down and compare them with what you actually used on site. That is how you build an estimate you can trust for the next job.
A Worked Example
Working through an example, with cost of material per unit area set to 10, room length set to 5, waste factor set to 2, the calculator returns room area of 500, and total material cost of 15,000, and total material area required of 1,500. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out total material area required?
Enter cost of material per unit area, room length, waste factor and room width. The calculator then works through the relationship and reports total material area required, total material cost and room area.
What does the flooring actually calculate?
It takes cost of material per unit area, room length, waste factor and room width and converts them into total material area required, total material cost and room area using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter cost of material per unit area?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Does anything you type get stored?
No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
