Terms and conditions

Agreement

By using this website you agree to these terms. If you do not agree, do not use the site.

The service

Cinder Block Calculator is a free estimating tool. It helps you count blocks and related materials from dimensions you enter. It is provided as-is, without a paid subscription and without a professional-services contract.

Estimates are not professional advice

Results are mathematical estimates only. They are not a material takeoff for a specific job, a structural design, or a substitute for:

• manufacturer data and local supplier coverage rates
• building codes, permits, and inspections
• drawings prepared by a qualified designer or engineer
• on-site judgment from a mason or contractor

Mortar bags, grout volume, waste, and cost depend on assumptions you can change. Actual quantities and prices will differ.

Your responsibility

You are responsible for checking inputs, confirming materials with your supplier, and following applicable law. Do not rely on this calculator as the sole basis for ordering, bidding, or building.

Acceptable use

Use the site lawfully. Do not attempt to disrupt it, scrape it in a way that harms service for others, or misrepresent the calculator’s output as certified engineering or as our endorsement of a project.

Intellectual property

Site design, copy, and software are provided for personal and commercial planning use of the calculator. You may print your own estimates. You may not copy the site as a competing product or remove notices in a way that suggests the tool belongs to someone else.

No warranty

The site is provided “as is” and “as available.” We do not warrant that calculations are error-free, that the site will always be online, or that it will meet a particular project’s needs.

Limitation of liability

To the fullest extent permitted by law, Cinder Block Calculator and its operators are not liable for leftover or short materials, construction defects, delay, lost profits, or other damages arising from use of the calculator or this website.

Privacy

How information is handled is described in the privacy policy.

Changes

We may update these terms. The date at the top of this page will change when we do. Continued use after an update means you accept the revised terms.
