Hi Product Hunt! I built Matholio because most home project calculators give you a number but never show how they got it. Before you buy paint, flooring, shingles or concrete, you should be able to check the math.
Every calculator shows the formula, the assumptions (coverage per gallon, waste factor, bag yield) and the steps, in US units. There are 12 calculators so far for paint, flooring, tile, roofing, concrete, gravel, fences, decks, drywall and lumber, plus a few practical guides. No sign-up, and any calculator can be embedded on your own site for free.
Which calculator should I add next? Feedback on the numbers is very welcome.
