Terms of Use
Last updated: October 2, 2026
What this site is
BuildMaterialPlanner.com provides free calculators that estimate material quantities and typical costs for home-improvement and construction projects (gravel, concrete, fencing, mulch, pavers, baluster spacing, rebar grids). By using this site, you agree to these terms.
Estimates only — not professional advice
Every result on this site is a planning estimate based on the formulas and national-average pricing shown on each page. Results are not:
- A contractor quote or binding price
- Engineering advice or a structural design
- A guarantee of local building-code compliance
- A substitute for confirming quantities and pricing with your supplier or contractor before purchasing
We built these tools to be genuinely useful for planning, and we try to keep the formulas and pricing accurate and current — but you're responsible for verifying anything before you spend money or start construction based on it.
No warranty
This site and its calculators are provided "as is," without warranty of any kind, express or implied. We don't guarantee the site will be error-free, uninterrupted, or that results will be accurate for your specific situation.
Limitation of liability
To the fullest extent permitted by law, we aren't liable for any loss or damage arising from your use of this site or reliance on its results — including over- or under-ordering materials, project delays, or costs beyond what a calculator estimated.
Third-party links
Some pages link to third-party suppliers, retailers, or contractor-matching services, including links that may earn us a referral commission (see our Privacy Policy). We aren't responsible for the content, accuracy, or practices of any third-party site you reach through these links.
Embedding our calculators
We offer free embeddable versions of our calculators for other websites (see Add a calculator to your site). You may embed them under the terms shown on that page; please don't modify, strip attribution from, or misrepresent the embedded tool as your own.
Changes
We may update these terms as the site changes. The "last updated" date at the top reflects the most recent change. Continued use of the site after a change means you accept the updated terms.
