Most tile calculators are black boxes built by template generators. ProTileCalc is a suite of free, transparent estimating tools built for contractors and serious renovators. It calculates tile waste (straight vs herringbone), grout by weight, and thinset by trowel notch. Every calculation is based on industry-standard TCNA methods and explicitly shows the governing formula so you can verify the math.

Hi Product Hunt! 👋 I built ProTileCalc because I was tired of "black box" material calculators that spit out a number without telling you how they got it. When you're ordering expensive tile, grout, and thinset, a 15% error can halt a project or waste hundreds of dollars. ProTileCalc is a suite of free estimating tools that actually "shows its work." 🛠️ What it does: Tile: Calculates area, boxes needed, and applies specific waste factors (e.g., +15% for Herringbone). Grout: Calculates by weight using TCNA industry-standard formulas for sanded, unsanded, and epoxy. Thinset: Coverage based on specific trowel notch sizes. I built this to be fast, ad-free, and fully transparent—every result displays the exact formula used. I'd love to hear your feedback on the UX and if there are any other specific calculators you'd like to see added!

Does the waste factor calculation account for the extra cuts needed at corners or around odd-shaped rooms, or is it purely a flat percentage based on total square footage?

The fact that you show the governing TCNA formula alongside each result is such a breath of fresh air. Way too many calculators expect you to just trust the number, and contractors especially need to verify the math before quoting a job.
