Formula-phobia is reasonable: most spreadsheet advice reads like tax law. This engine is three one-line formulas doing three jobs — add up each envelope, add up the month, flag what's overspent. You type date, envelope, amount; the sheet does the rest.
SUMIFS: 'add up everything tagged dining-out'. The rollup: 'add up the month so far'. The flag: 'turn red past the limit'. Three sentences, three lines — if one breaks, you know which sentence to check.
No plugins, no scripts, no connected account. The file opens in Sheets, Excel, or LibreOffice ten years from now exactly as it opens today.
Ships with a sample month so the rollups work on import. Budget Sheets Port ($15).
