CalcForHome is a collection of free, browser-based calculators for DIY concrete and gravel projects: slab volume in cubic yards, bag counts for 80/60/50/40 lb mixes, gravel tonnage by stone type, concrete per fence-post hole, and code-cited frost depth for all 50 states. Everything runs locally in your browser — no sign-up, inputs never leave your device, results in under a second.

I kept re-doing the same napkin math on every concrete job — how many bags, what a yard actually costs, how deep a footer goes before frost heave cracks it — so I built the calculators I wanted to use.
Everything runs client-side, no signup, and the frost-depth tool cites the actual code section for each of the 50 states (including the 22 split-zone ones), with a downloadable CSV.
Feedback I'd love: which calculator is missing from your toolbox? Gravel depth for RV pads and paver sand are next on the roadmap.
