Affiliate disclosure
CementCalc is free to use. Here is exactly how it is paid for, in plain terms.
Quick answer
Affiliate links
CementCalc is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. Product links on this site are affiliate links and are marked as sponsored.
Prices and availability shown on Amazon at the time of purchase apply. We do not set prices, hold inventory, or handle returns — those are between you and the retailer.
Products are chosen to match the calculation on the page: a rebar takeoff lists the bar size you selected and the chairs to hold it, a paver takeoff lists jointing sand and edge restraint. Commission rates do not vary meaningfully between the items shown, so recommendations are not steered by payout.
Advertising
Display ads on this site are served by third-party ad networks, which may use cookies to measure performance and limit repeat impressions. Ads are kept out of the calculator input and result areas so they never interfere with using a tool.
No professional relationship
CementCalc provides quantity estimates for planning. It does not provide engineering, design or code-compliance services, and using the site does not create a professional relationship. Confirm structural requirements with your local building department or a licensed professional — see how our numbers are calculated.
