Slab Volume Calculator

Volume of slabs by method, with rebar and form-work estimates.

What this workbook is

A real, downloadable Microsoft Excel workbook — not a rendered demo. Every sheet is built around a single engineering method: inputs in one place, calculated results and a PASS / WARN / FAIL check sheet, with the method, sources and assumptions recorded next to the numbers. Open it in Excel, Sheets or LibreOffice, change the inputs, and the workbook recalculates.

  • Light cells are user-entered inputs on the Inputs sheet.
  • Dark cells are calculated automatically and are not editable.
  • The method and sources for every calculation are listed below and inside the workbook.
