Tile & Marble Cost Calculator

What will my tile and marble work cost?

You know roughly how much tile and marble you need — tile in the rooms, hall and bathrooms; marble on the kitchen floor and platform, the windows and the stairs. What is harder to add up is everything around it: the extra pieces for skirting, wastage from cutting, the laying labour, the sand and cement under the floor, grout and white cement for the joints, and the small expenses that always turn up.

This calculator does that adding up. Enter your tile area, your two marble areas, the rates you have been quoted and the labour charges; skirting, wastage, setting materials and an extra-expenses allowance are added automatically. Both tabs feed one project total, with the arithmetic behind every figure.

How this calculator works

Enter the areas you have worked out yourself — there is no need to measure room by room. Marble is entered in two parts because the labour differs: the floor and kitchen platform, and the windows and stairs. The areas you enter never change; labour and the average cost per sq ft are based on them.

Skirting is worked out for you. It runs along the walls, so what matters is the wall length, not the floor area: a 12 × 12 ft room is 144 sq ft but has only 4 × 12 = 48 ft of wall, and 6-inch skirting along it is 48 × 0.5 = 24 sq ft. That is one-sixth of the floor, so the calculator adds area ÷ 6 — 110 sq ft for 660 sq ft of tile. Untick the box if you do not want skirting.

Wastage is added on the area plus skirting — 5% for tile and 7% for marble. Skirting and wastage are rounded up to whole sq ft, so 660 sq ft of tile becomes 660 + 110 = 770 sq ft, plus 39 sq ft of wastage: 809 sq ft to buy. The material cost is that quantity times your rate.

Labour is charged on the area you entered, never on skirting or wastage. Each marble section has its own labour rate per sq ft — windows and stairs take more finishing work than a floor.

Sand, cement, white cement and grout are estimated from consumption per sq ft and rounded up to whole bags, kilograms and CFT. Extra expenses are a fixed 3% of everything before them. The setting-material quantities lean to the upper end of the usual ranges, so the estimate is not on the low side.

Formula

Skirting          = Floor area × 4 × 0.5 ft ÷ 12 ft  (= area ÷ 6)
Subtotal          = Area + Skirting
Wastage           = Subtotal × 5% (tile) or 7% (marble)
Total required    = Subtotal + Wastage
Material          = Total required × Rate
Labour            = Area × Labour rate        (no skirting, no wastage)

Marble area       = Floor & platform + Windows & stairs
Marble skirting   = on the floor & platform area only

Sand (CFT)        = (Tile + Marble area) × 0.115, rounded up
Cement (bags)     = (Tile + Marble area) × 0.025, rounded up
White cement (kg) = Marble area × 0.06, rounded up
Grout (kg)        = Tile area × 0.03, rounded up

Subtotal          = Material + Labour + Supporting materials
Extra expenses    = Subtotal × 3%
Total             = Subtotal + Extra expenses
Average per sq ft = Total ÷ (Tile area + Marble areas)

Worked example

1. 660 sq ft of tile at ₹60 (₹20 labour); marble at ₹120 — 250 sq ft of floor and platform (₹160 labour) and 50 sq ft of windows and stairs (₹180 labour).
2. Tile material ₹48,540 and marble material ₹43,920; labour ₹62,200 in all; supporting materials ₹20,900.
3. Subtotal ₹1,75,560 plus 3% extra expenses ₹5,267 gives a total project cost of ₹1,80,827 — about ₹188 per sq ft.

A worked example: tile in the rooms, marble in the kitchen

Two rooms, a hall, a kitchen and bathrooms, measured by the owner as 660 sq ft of tile, 250 sq ft of marble on the kitchen floor and platform, and 50 sq ft of marble on the windows and stairs. Tile is ₹60 a sq ft with ₹20 labour; marble is ₹120 a sq ft, with ₹160 labour for the floor and platform and ₹180 for the windows and stairs.

How skirting is estimated

Skirting covers the bottom of the walls, so it depends on how long the walls are. A total floor area does not say that, so the calculator assumes typical rooms of about 12 × 12 ft with 6-inch skirting.

Small rooms need proportionally more skirting and big halls less; 12 × 12 ft rooms sit in the middle. Doorways need no skirting, which roughly offsets the extra cutting at corners.

Why you enter a rate, not a tile or marble type

Two vitrified tiles can differ in price by five times, and marble ranges from under ₹60 to several hundred rupees a sq ft depending on the stone, grade, thickness and city. A list of types with built-in prices would be wrong for most people.

Enter the rate on your supplier’s quotation and the estimate reflects exactly what you are buying, wherever you are buying it.
