Tested before release
Both files were tested with the sample data in Excel (Excel for the web) and Google Sheets: all 16 expected results matched (totals, single rows, blank rows, cross-sheet values and percentages, each worked out separately), with no formula errors across 451 formulas.
No macros, no add-ins, no external links. Input cells are blue text on light amber. In the Excel file, formula cells are locked with no password so they don't get typed over by accident.

Who it's for
Interior painters and painting contractors who price by room.

Not the right fit if
You price exterior work by elevation or siding type. You can enter walls as rows, but the sheet is built around rooms.
