Tile Cost Calculator
Calculate the total cost of a tile flooring project including materials, labor, waste, and taxes.
Formula & Explanation
Total project cost is calculated as: 1. Calculate room area: Area = Length × Width 2. Calculate tiles needed: Tiles = Ceiling(Area ÷ Tile Area × (1 + Waste Factor)) 3. Calculate material cost: Material = Tiles × Price Per Tile 4. Calculate labor cost: Labor = Area × Labor Cost Per Sqft 5. Calculate subtotal: Subtotal = Material + Labor 6. Calculate tax: Tax = Subtotal × Tax Rate 7. Calculate total: Total = Subtotal + Tax All monetary amounts are in dollars.
Assumptions
- •Room is rectangular with perpendicular walls
- •Labor rate is applied to the full room area, not adjusted for waste factors
- •Tile price is the unit cost; no volume discounts are calculated
- •Tax is calculated on both material and labor costs combined
- •Waste factor percentage is typical: 10% for straight patterns, 15% for diagonal
- •Installation includes basic labor; additional costs (demolition, prep work) are not included
Example Calculation
A 12×12 ft room (144 sqft) with 12×12 inch tiles ($3 each) and $4/sqft labor. With 10% waste (158 tiles), material costs $474, labor $576, tax $84, for a total of $1,134.
