Acceptance of terms
By accessing and using Material Tally, you accept and agree to be bound by these Terms of Service. If you do not agree to these terms, please do not use our calculators.
Use of calculators
Material Tally provides free calculators for estimating materials needed for home improvement projects. You may use these calculators for personal or commercial projects at no cost.
You agree to use the calculators responsibly and not to misuse, abuse, or attempt to disrupt the service.
Calculator pages may include related guides, FAQs, assumptions, and internal links to help you understand the result. You agree that these supporting materials are general educational content and that final project decisions remain your responsibility.
Disclaimer of accuracy
IMPORTANT: All calculations provided by Material Tally are estimates for planning purposes only. These estimates are NOT professional, construction, engineering, or legal advice.
Material Tally makes no warranties or guarantees about the accuracy, completeness, or reliability of any calculations. Actual material requirements may vary based on:
- Product specifications and manufacturer recommendations
- Site conditions and installation methods
- Local building codes and regulations
- Weather conditions and material quality
- Installer skill and experience
You are solely responsible for verifying all estimates with product specifications, supplier recommendations, local building codes, and professional guidance before purchasing materials or starting construction.
Professional consultation
Material Tally is not a substitute for professional advice. For structural, safety-critical, or complex projects, always consult with licensed contractors, engineers, architects, or other qualified professionals before proceeding.
Your responsibility when using estimates
You are responsible for entering accurate measurements, selecting assumptions that match the product you plan to buy, and reviewing calculator results before relying on them. Defaults such as waste percentage, coverage rate, density, bag yield, or box coverage are general planning aids. They may not match the material available from your supplier.
Before purchasing, compare the estimate with manufacturer instructions, supplier recommendations, delivery requirements, return policies, and any permit or inspection requirements. If a project involves structural support, safety, drainage, utilities, or property boundaries, seek qualified local guidance before starting work.
Limitation of liability
Material Tally and its operators shall not be liable for any damages, losses, or expenses arising from:
- Use or reliance on calculator results
- Errors or inaccuracies in calculations
- Material shortages or overages
- Project delays or cost overruns
- Construction defects or failures
- Code violations or permit issues
You use Material Tally at your own risk. We provide the calculators "as is" without any warranties of any kind.
