About CreateCalc
Free, accurate material calculators for everyone who builds, renovates, or fixes things.
What we do
CreateCalc is a 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.
