About Construction Calculator

Construction Calculator is designed and built by Solosoft, a software company focused on practical, dependable digital products.

This site exists because construction math deserves better than black-box answers. Every calculator on this site:

• Is built from a written formula specification before any UI exists
• Is covered by automated reference tests — over a hundred verified cases including boundary values and imperial/metric parity
• Shows its formula, worked steps and assumptions next to every result

The site runs entirely in your browser. No account, no database, no tracking of your measurements. Calculations keep working offline after your first visit.

Who reviews the math

Formulas follow standard industry practice: published bag yields, IRC stair guidance, nominal lumber sizes, and standard rebar weight tables. Results are estimates — see our calculation disclaimer.
