Construction and material estimates

Plan material quantities with clear, practical calculators.

Focused tools for concrete, gravel, and paint—built to show the method, assumptions, and units behind every estimate.

Focused scope

Three material calculators

The first release stays deliberately narrow so each calculator can be accurate, useful, and easy to understand.

Available Concrete calculator

Estimate wet concrete volume and common bag quantities for a rectangular slab.

Available Material calculator

Estimate the volume and weight of gravel for a rectangular area.

Available Material calculator

Estimate paint required from wall area, openings, coats, and coverage.

Built for the job at hand

Every value carries an explicit unit and practical guidance.

Methods, waste allowances, and rounding are visible.

A restrained, mobile-first experience keeps the result in focus.
