Global project calculators

Measure the project. Know what to buy.

BuildAmounts helps homeowners, builders and DIYers estimate material quantities using clear calculators that support both metric and US measurements.

Launch calculators

Our first tools focus on the material and measurement questions people need to answer before buying supplies or starting work.

Estimate concrete volume, waste allowance, and purchase quantity in metric or US units.

Calculate project area and convert between square feet, square meters, and common area units.

Estimate paint needed from wall dimensions, openings, coats, coverage, and waste.

Estimate gravel volume and material quantity for driveways, paths, and landscaping projects.

Calculate mulch volume for beds and landscaping using metric or US measurements.

Estimate concrete specifically for slabs, including thickness, waste, and purchase quantities.

Estimate board area, sheet count, waste allowance, and material needs for walls and ceilings.

Estimate fence length, panels, posts, spacing, and project material quantities.

Each calculator is being designed to turn project dimensions into practical quantities you can use to plan purchases.

Use measurements that make sense for your country and project instead of forcing one regional system.

Add a practical waste allowance and see both the raw amount and a recommended purchase quantity.

Concrete, paint and gravel are only the start. Flooring, tile, roofing, landscaping and cost tools are planned next.
