Hi Product Hunt, I'm Emre, a developer from Istanbul. Buying materials is where most DIY projects go wrong: too few bags of concrete means a second trip mid-pour. Most calculators online give you a number but never say where it came from. ShedMath shows its work. Bag yields come from Quikrete's data sheets, deck joist spans from the American Wood Council's DCA 6 guide, and mulch depths from university extension services. Every page has the formula and a worked example, so you can check the math yourself. It's free, needs no account and runs in your browser. Which calculator should I build next?
