Welcome to Bonrockco's Construction & Landscaping Material Calculator Suite, the most comprehensive set of tools designed to help both DIY enthusiasts and professional contractors accurately estimate materials for their projects.
Our calculators eliminate the guesswork from material estimation, helping you avoid costly over-purchasing or frustrating under-ordering. Whether you're planning a small backyard patio or a large commercial landscaping project, our tools provide precise calculations for all your material needs.
Developed by construction professionals with decades of field experience, these calculators incorporate real-world factors like material compaction, wastage, and practical application considerations that simple volume calculators often miss. We've done the math so you don't have to, translating complex material calculations into easy-to-use interfaces.
Beyond basic calculations, our suite offers advanced features like multiple unit conversions, material type adjustments, and customizable wastage factors. This attention to detail ensures your estimates match real-world requirements, helping you stay on budget and on schedule.
Regularly updated with the latest industry standards and material specifications, Bonrockco calculators have become trusted tools for thousands of construction professionals across North America. Join them today and experience the difference precision planning can make for your projects.
Select a material type to see specific information about density, coverage, and typical uses.
Our calculators go beyond basic volume calculations to include material weights, bag quantities, cost estimates, and project-specific adjustments.
Developed with input from construction professionals, our calculators account for real-world factors like compaction, wastage, and material characteristics.
Easily switch between imperial and metric units, or convert between different measurement types (linear, square, cubic) as needed for your project.
Generate printable reports with all your calculations, material lists, and cost estimates for easy reference and project planning.
Get approximate project costs based on current regional material prices, helping you budget accurately before starting work.
Access our calculators from any device, whether you're in the office, at the supply yard, or on the job site.
Choose from our suite of calculators based on your project needs. We offer specialized tools for aggregate materials, concrete mixes, pavers, and retaining walls.
Input the measurements of your project area. For most calculators, you'll need length, width, and depth/height measurements. Use the unit selectors if you need to switch between feet/inches and meters/centimeters.
Choose the specific material type you'll be using. Different materials have different densities and characteristics that affect the calculations. Our calculators include presets for common materials.
Many calculators include advanced options like wastage factors, mix ratios, or special additives. These let you fine-tune the calculations for your specific project requirements.
The calculator will display detailed results including material quantities, weights, and cost estimates. You can print these results or save them for reference during your project.

"The concrete calculator's strength options match exactly what we specify in our commercial projects. It's become part of our standard estimating process."
Our calculators provide professional-grade accuracy when used with correct measurements. They account for standard material densities, compaction factors, and typical wastage. However, actual requirements may vary slightly based on specific site conditions, material batches, and application techniques. We recommend adding a 5-10% safety margin to your final order.
Yes, many professional contractors use our calculators for initial estimates and project planning. However, for large commercial projects or engineered structures, we recommend verifying calculations with a qualified engineer or materials specialist, especially when dealing with load-bearing applications or specialized mixes.
Cost estimates are based on average regional material prices from major suppliers across North America. These are updated quarterly but may not reflect local price variations or seasonal fluctuations. The estimates are intended for budgeting purposes only—actual prices should be confirmed with your local suppliers.
Gravel is naturally occurring, rounded stone collected from riverbeds or glacial deposits, making it ideal for drainage and decorative applications. Crushed stone is mechanically crushed angular rock, which interlocks better for structural applications like driveways and road bases. Our calculators account for their different densities and compaction characteristics.
Paver bases (typically compacted gravel) primarily need to provide drainage and prevent settling under foot traffic. Retaining wall bases must resist lateral earth pressures, requiring different gradations and compaction. Our calculators automatically adjust base material recommendations based on the structural requirements of each application.
For irregular shapes, break the area into smaller regular shapes (rectangles, triangles, circles), calculate each separately, then sum the results. Our blog has detailed guides on measuring complex areas. For highly irregular projects, consider using our maximum length/width dimensions to ensure adequate material coverage.
Currently, you can print or download your calculation results as PDFs. We're developing account features that will allow saving projects and accessing calculation history. Sign up for our newsletter to be notified when these features launch.
PSI (pounds per square inch) measures concrete's compressive strength. Higher PSI mixes (4000-5000) are for heavy loads (driveways, foundations), while lower PSI (2500-3000) suits sidewalks or decorative work. Our calculator adjusts mix ratios accordingly—stronger mixes require more cement, affecting both cost and material quantities.
Construction material prices can fluctuate monthly due to fuel costs, demand, and supply chain factors. While we update our baseline prices quarterly, we recommend checking with local suppliers for current rates when finalizing budgets, especially for large orders or projects scheduled several months out.
We regularly add new calculators based on user requests. If you need calculations for a specialized material or application, contact us with details about your requirements. Our team can often create custom solutions or recommend workarounds using our existing tools.
Our calculators are developed with input from professional contractors and engineers, incorporating real-world factors that generic calculators overlook.
From initial base materials to finishing touches, our suite covers all aspects of construction and landscaping projects in one place.
Adjust wastage factors, mix ratios, and material types to match your specific project requirements and local conditions.
Avoid over-ordering (wasting money) or under-ordering (costly delays) with calculations that hit the sweet spot for material quantities.
Our detailed blog and guides help you understand the "why" behind the calculations, making you a more informed builder.
