Cost per sq ft of floor

You buy 341.0 sq ft of tile for 300 sq ft of floor, 13.7% extra, including 10% for cuts and breakage. Laying charges are not included.

Quick answer: Multiply the room’s length by its width, add about 10% for cuts, divide by the area of one tile and round up to whole boxes. A 20 × 15 ft room in 600 × 600 mm tiles needs 86 tiles, or 22 boxes of 4; at ₹ 100 a sq ft the boxes cost ₹ 34,100.

How do you use the tile calculator?

Enter the room’s length and width in feet and pick the tile size.
Enter how many tiles come in a box (it is printed on the box or the dealer’s price list) and the price.
Read the boxes to buy and the cost. Wastage, laying charges, adhesive and other tile sizes are under “Adjust wastage, labour and tile size”.

How many tiles do you need for a room?

Multiply the room’s length by its width to get the floor area, add an allowance for tiles cut at the edges and broken on site, and divide by the area of one tile. Round up, then round up again to whole boxes, because dealers sell by the box. You pay for every tile in those boxes, so the calculator prices the boxes, not just the floor area.

Tile sizes are in millimetres. A 600 × 600 mm tile is about 1.97 ft a side and covers 3.88 sq ft, not 4 sq ft. Count it as a 2 ft tile and a 300 sq ft room comes out at 83 tiles; the true count is 86.

How the quantities are worked out

Floor areaLength × width (sq ft)

TilesFloor area × (1 + wastage %) ÷ area of one tile, rounded up

BoxesTiles ÷ tiles per box, rounded up

CostBoxes × tiles per box × tile area × price per sq ft (or boxes × price per box) + laying + adhesive

Worked example: 20 × 15 ft living room

The floor is 300 sq ft. With 10% for cuts, 600 × 600 mm tiles need 86 tiles, or 22 boxes of 4. The boxes hold 88 tiles (341.0 sq ft), so at ₹ 100 a sq ft the tiles cost ₹ 34,100.

Worked example: 12 × 10 ft bedroom in 800 mm tiles

The floor is 120 sq ft. 800 × 800 mm tiles at 3 to a box need 20 tiles in 7 boxes. At ₹ 120 a sq ft for 144.7 sq ft of tile, plus ₹ 40 a sq ft for laying and ₹ 2,500 of adhesive and grout, the floor costs ₹ 24,660, or ₹ 206 a sq ft.

How does tile size change the count?

The 20 × 15 ft room, 10% wastage, ₹ 100 a sq ft. Tiles per box are examples; use the figure on your box.
Tile size	Per box	Tiles	Boxes	Tile cost
300 × 300 mm	10	341	35	₹ 33,906
600 × 600 mm	4	86	22	₹ 34,100
800 × 800 mm	3	48	16	₹ 33,067
600 × 1200 mm	2	43	22	₹ 34,100

What else should you check before buying tiles?

Buy all the boxes from one batch. Shade and size can vary between batches, and the batch number is printed on the box.
Keep a few spare tiles for future repairs.
Ask whether the laying rate includes adhesive, grout, spacers and removing old flooring.

Frequently asked questions

The calculator starts at 10% for cuts at the walls and breakage on site, and you can change it. Diagonal laying, many corners or large tiles in a small room waste more. Rounding up to whole boxes adds a little more, which also gives you spares for repairs later.

Multiply the length by the width in millimetres and divide by 92,903, the number of square millimetres in a square foot. A 600 × 600 mm tile covers 3.88 sq ft. An 800 × 800 mm tile covers 6.89 sq ft, and a 600 × 1200 mm tile covers 7.75 sq ft.

Dealers price per sq ft so tiles of different sizes can be compared, but they sell whole boxes. You pay for all the tiles in every box you buy, so the cost is the area in your boxes times the rate, which is a little more than the floor area plus wastage.

It depends on the brand, size and thickness. Larger tiles come fewer to a box. The number is printed on the box and usually on the dealer’s price list, along with the area the box covers. Enter it here; the table on this page uses example figures only.

Only if you enter a laying charge. Add the rate per sq ft from your contractor and a lump sum for adhesive, grout and spacers under the adjust options. Ask whether the laying rate includes removing the old floor and levelling, which some contractors charge separately.

Yes. Enter the wall’s width as the length and its height as the width, and leave out doors and windows by reducing the size. Kitchen and bathroom walls have more cuts around fittings, so a higher wastage allowance is sensible.
