PROJECTCALC / OUR STANDARDS

About ProjectCalc

ProjectCalc is an independent toolbox for contractors, builders, estimators, tradespeople and serious DIY users. Our purpose is simple: turn field measurements into quantities you can check and use.

Tools for the work ahead

Our first tools cover fences, concrete, gravel, area, volume and unit conversion. They accept metric and imperial measurements, including construction fractions, and distinguish a raw quantity from an order with waste allowance.

We build for the small screen you have on site. Inputs are large, results are direct and no account is required. You can copy, print, share or explicitly save a calculation on your device.

Precision before presentation

Each calculator includes its formula, assumptions, reference values and a worked example. We keep calculation logic separate from the interface and verify it with automated reference cases. Read our methodology to see what the tools do and where their scope ends.

How this property is supported

ProjectCalc is intended to be supported by advertising. Reserved advertisement areas keep future ads separate from calculator controls. Advertising is not currently active. Optional, consent-controlled analytics helps us understand tool usage; see our privacy policy.

Help improve the toolbox

If a result seems wrong, send the dimensions, units, allowance and expected answer through our contact page. Specific, reproducible examples help us improve the tools.
