About cubicyard.tools

cubicyard.tools builds free material calculators for people who work with their hands — DIY homeowners, weekend warriors, and professional contractors alike.

Every tool on this site is free, ad-supported, and requires no sign-up. We built them because we got tired of calculators buried under marketing copy, slow to load, or requiring an email address just to see a bag count.

The calculators use industry-standard formulas and constants. We document every formula so you can verify the math yourself.
