About Us

The Tonnage Calculator exists because landscapers, contractors, and DIYers often face the same question: “How much material do I actually need to order?”

I wanted a calculator that makes the answer immediately obvious. Enter your dimensions, choose your material, and the calculator instantly estimates the required tonnage. The tool helps you plan your project and budget accurately, so you don't over- or under-buy materials like gravel, sand, or soil.

What we care about

• Accuracy first. Calculations are based on standard volume and density formulas.
• Privacy by default. No login or account is required to use the tool.
• Speed & clarity. The interface is clean, fast, and mobile-friendly—use it on-site to get quick estimates.
• Accessibility. Clear typography, easy input fields, and keyboard navigation support.

Friendly reminders

• This is an estimation and planning tool—not a substitute for professional advice or supplier-specific data.
• Material densities (unit weights) can vary based on moisture content, compaction, and source. Always confirm with your material supplier if precision is critical.

Roadmap

• Calculations for different shapes (e.g., cylinders for post holes)
• Cost estimation based on price per ton/yard
• An expanded library of pre-defined materials
• Metric + Imperial switching
• Export results as a PDF summary

Brand note

This tool is independent and not affiliated with any material supplier or engineering firm. Always confirm quantities and material specifications with your supplier before placing an order.
