Terms of Use

Last updated October 7, 2026

By using wheelbarrowmath.com you agree to these terms.

Estimates, Not Advice

The calculators and guides give estimates for planning. Real projects vary: materials settle, suppliers measure differently, sites are uneven, and prices change. Confirm quantities, prices, and installation requirements with your supplier, the product manufacturer, or a qualified professional before you buy or build.

Structural work deserves particular care. Retaining walls, driveways, and anything that holds back soil or carries vehicles may need an engineered design and a permit. Nothing on this site replaces that.

No Warranty

The site is provided “as is”, without warranties of any kind, including accuracy, fitness for a particular purpose, or uninterrupted availability. To the fullest extent the law allows, WheelbarrowMath is not liable for any loss or damage arising from your use of the site, including over- or under-ordering materials.

Links and Ads

We link to other sites for reference and show third-party ads. We don’t control those sites or advertisers and aren’t responsible for their content, products, or practices.

Content

The text, calculators, and design of this site belong to WheelbarrowMath. You’re welcome to share links and quote short passages with attribution. Please don’t copy whole pages or calculators.
