Free, accurate calculators that help you order the right amount of material — every time.
ConcreteCalcTools builds free online calculators for concrete, gravel, asphalt, drywall and other construction materials. Every tool uses standard, industry-accepted formulas so contractors and homeowners can plan jobs, control costs and avoid waste.
The site is owned and operated by Chris Terry through Encore Promotional Products. We’re committed to calculators that are accurate, fast and genuinely useful — no sign-ups, no clutter.
All results are estimates based on typical material densities and yields. For significant projects, confirm quantities with your supplier or a qualified professional before ordering.
