About Smart Tile Calculator
Smart Tile Calculator exists for one reason: nobody should drive back to the tile store because they ordered one box short. We build free calculators that turn a tape measure reading into a real shopping list — tiles, boxes, grout, thinset, trim and total cost.
How our calculators are built
Every tool uses published industry formulas and manufacturer coverage rates: standard grout volume math, trowel-notch coverage charts for thinset, and waste allowances that match how much tile actually gets cut in each layout pattern. Nothing is a guess dressed up as a number.
How we keep them accurate
- Material prices reviewed against national retail pricing each year.
- Labor ranges cross-checked against contractor quote data.
- Coverage rates taken from mortar and grout manufacturer data sheets.
How we pay for it
The calculators are free and always will be. We earn a small commission when you buy a tool or material through an Amazon link on this site, at no extra cost to you. That funds the hosting and the research — it never changes the math.
Part of a tool network
We also build Smart Roofing Calculator and Smart Decking Calculator, using the same approach: real formulas, no sign-ups, no paywalls.
