Calculation Results
Tile & Setting Materials Formula
Boxes = ⌈(Area × (1 + Waste %)) / Sq Ft per Box⌉ | Mortar Bags = ⌈Area / 45⌉ | Grout Bags = ⌈Area / 100⌉- Tile Waste Buffer: 10%–12% for straight lay; 15%–20% for diagonal, herringbone, or small mosaics.
- Thinset Mortar: 1 50-lb bag covers approximately 45–50 sq ft with a 1/4" × 3/8" notched trowel.
- Grout: 1 25-lb bag of sanded grout covers approximately 100–120 sq ft for standard 12x12 tile.
Step-by-Step Worked Example
Scenario: Tiling 300 sq ft of kitchen floor with porcelain tile in 15 sq ft boxes with 12% cut waste
Calculation Steps:
- Area with Waste = 300 × 1.12 = 336 sq ft
- Boxes of Tile Needed = ⌈336 / 15⌉ = 23 boxes (345 sq ft)
- Tile Material Cost = 345 sq ft × $5.50 = $1,897.50
- Thinset Mortar (300 / 45) = 7 bags × $22 = $154.00
- Grout (300 / 100) = 3 bags × $26 = $78.00
- Spacers & Sundries = $35.00
- Installation Labor = 300 sq ft × $7.50 = $2,250.00
- Total Project Cost = $1,897.50 + $154 + $78 + $35 + $2,250 = $4,414.50
Result: The project requires 23 boxes of tile, 7 mortar bags, and 3 grout bags, totaling $4,415 ($14.72/sq ft installed).

- Always obtain multiple written bids from licensed, bonded, and insured contractors before commencing work.
Frequently Asked Questions
Should I use sanded or unsanded grout?
Use sanded grout for grout joint lines 1/8" or wider to prevent cracking. Use unsanded grout only for tight joint lines narrower than 1/8" (such as polished marble or glass tiles that scratch easily).
