About QuantityCalc
Free construction and landscaping calculators that tell you both how much material you need and roughly what it will cost.
What we do
Most online calculators stop at a quantity — cubic yards of gravel, bags of concrete, sheets of drywall. That is only half the question. QuantityCalc pairs every quantity with a localized cost estimate built from national-average prices and a regional adjustment, so you can budget a project, not just measure it.
Who it's for
Contractors pricing a job, landscapers ordering bulk material, and DIY homeowners planning a weekend project. The tools are mobile-first and work without a sign-up — punch in your dimensions and get an answer instantly, then copy or print the result for the supplier.
How we keep it trustworthy

Every calculator shows the formula and the numbers behind its result.
