StructureCalculator helps contractors, landscapers, homeowners, and DIYers estimate construction materials before ordering. Calculate gravel, crushed stone, asphalt, concrete, mulch, tile, grout, roof pitch, stairs, and more using supplier-ready units like cubic yards, tons, bags, and boxes. Every calculator documents the formulas and references used, making the results transparent and easy to verify.

I built StructureCalculator after noticing that many online construction calculators were either overly simplistic, cluttered with ads, or hid the formulas behind the results. That makes it difficult to trust the numbers when you're ordering materials that can cost hundreds or thousands of dollars. My goal was to create a collection of calculators that are fast, easy to use, and transparent. Each calculator explains the formulas it uses, cites reliable references where appropriate, and returns results in the units suppliers actually quote—such as cubic yards, tons, bags, and boxes. This is the first public launch with 20 construction and DIY calculators, and I'm continuing to expand the library based on user feedback. If there are calculators you'd like to see added or ways the existing ones could be improved, I'd love to hear your suggestions.

honestly this looks super useful for planning material orders. one thing though, it would be really helpful to have a built-in cost estimator that pulls local pricing data, so you can get a rough budget alongside the quantity. that would basically make it a one-stop shop before talking to suppliers

Love that every calculator shows its formulas and references instead of just spitting out a number. That kind of transparency is rare and super useful when you're trying to double-check a quote.
