Tile Cost Calculator
Tile, thinset and installation labour for a floor, priced as one installed total.
Tile pricing is where homeowners most often compare the wrong numbers. The shelf price is per square foot of material; the number that decides the project is per square foot installed, and the two can differ by a factor of three once labour is counted in.
The material spread is also wider than for almost any other finish. Ceramic starts around a dollar a square foot, porcelain two to five, natural stone six and up, and large-format slabs can pass twenty. Labour moves the other way: big tiles look expensive on the shelf but install faster per square foot, while small mosaics are cheap per box and slow to lay.
How this calculator works
Every field is editable and the result updates as you type — nothing is submitted anywhere, all the maths runs in your browser. That matters for a number you are about to spend money on: you can see exactly which input moved the answer, and by how much.
What this calculation assumes
Assumes a sound, flat substrate and a standard thin-set installation. Floor levelling, backer board, uncoupling membrane, grout and removal of an existing floor are all excluded, and each can add several dollars per square foot.
Treat the result as an order-of-magnitude check rather than a final quantity. Product packaging changes, regional labour rates vary by a factor of two, and no calculator has seen your actual site.
Frequently asked questions
Why does labour cost more than the tile?
Because laying tile is slow, skilled work. Setting, spacing, cutting around obstacles and grouting a floor takes an experienced installer most of a day per 100 square feet. On a mid-range porcelain floor it is normal for labour to be two to three times the material cost.
Does a larger tile cost less to install?
Usually yes, per square foot — fewer pieces means fewer cuts and fewer grout lines. The counterweight is that large-format tile needs a flatter substrate and often a levelling system, so any floor levelling moves onto the bill. Below about 8 inches, installation cost climbs quickly.
What is not included in this estimate?
Grout, backer board or uncoupling membrane, floor levelling compound, and removal of the old floor. On a slab that is out of level, the levelling alone can add several dollars per square foot, and old tile removal adds labour and disposal fees.
