About this calculator
Add your rooms, choose the tile size and fixing method, and get the tiles and boxes to buy, adhesive bags, grout packets and the cost — tiles at Rs 2,250 – 2,600 per sqm, adhesive Rs 700 per bag, filler Rs 400 per packet.
How it's calculated
- Tiles = floor area × (1 + wastage) ÷ tile face area
- Boxes = tiles ÷ tiles per box (rounded up)
- Adhesive 3.5–5 kg per sqm by tile size (20 kg bag); mortar bed 1:4 at 1″ thick
- Grout kg/sqm = (L + W) ÷ (L × W) × joint × depth × 1.6
How much wastage should I allow?
7% for straight laying in normal rooms, 10–15% for diagonal laying or many small rooms.
