What This Calculator Does

The Flooring and Tile Calculator estimates whole boxes or tiles from a measured net area, a waste allowance and product coverage. Tile mode uses tile dimensions and optionally tiles per box. An optional unit price adds a material budget based on what you buy.

When to Use It

Use it after measuring your floor. Combine shapes and subtract excluded regions with square footage. For depth-based materials use concrete. This tool plans area coverage rather than material volume.

Inputs Explained

Net area must be positive in ft² or m². Waste is 0–100%; the editable 10% default is an example, not a universal recommendation. Box mode uses the package’s coverage per box. Tile mode uses positive length and width in inches, centimetres, feet or metres. Optional tiles per box must be an integer from 1 to 1e6. Leave prices blank to omit cost, or enter zero for free material.

Whether doorways, fixed cabinets or other regions should be deducted depends on the actual installation scope. The calculator cannot identify these regions automatically. Add covered regions and subtract exclusions first, then enter the measured net area. Waste allowance and surplus caused by whole-package rounding are separate.

Set the editable ten-percent example to zero to inspect the base purchase quantity, or enter the allowance agreed for your project. Layout direction, material and room boundaries can affect waste; this calculator does not choose the appropriate allowance for a particular installation.

How the Calculation Works

Required area = net area×(1+waste/100). Boxes = ceiling(required area/box coverage). Tile area = length×width. Tile count rounds up first; when a package size is given, box count rounds up again. Purchased area uses the actual purchased pieces. Only floating-point noise close to an exact integer is ignored.
