About CreateCalc
Free, accurate material calculators for everyone who builds, renovates, or fixes things.
What we do
CreateCalc is a growing collection of free calculators for building and home-improvement projects. Tell a calculator your dimensions and it returns a clear shopping list — cubic yards, bags, boxes, gallons — along with an optional cost estimate.
Who it's for
Whether you're a weekend DIY homeowner pouring a patio, a small contractor pricing a job, or an investor estimating a renovation, the goal is the same: buy the right amount of material the first time. No more guessing in the aisle or making a second trip.
How we keep results accurate
Each formula is checked against worked examples and industry rules of thumb, and every calculator includes a waste allowance because real-world subgrade, offcuts, and breakage are never zero. Results are still estimates — always confirm against a supplier quote and your local building code before buying.
How it's free
CreateCalc is supported by advertising and, where relevant, affiliate links to materials. The calculators themselves are, and will stay, free to use with no sign-up required.
