How this calculator works
Net area = floor length × floor width − deductions
Tiles = net area × (1 + wastage ÷ 100) ÷ area of one tile, rounded up
Cost = tiles × price per tile
Assumptions and limits
- Joint (grout) width is not added to the tile size. Include it in the tile size if needed.
- Wastage of about 5–15% is often allowed depending on the layout and tile size; choose your own.
