Monthly budget (zero-based)
Income, three expense groups, and a live “left to assign” figure that reaches zero when every dollar has a job.
Works in Excel, Google Sheets, Apple Numbers and LibreOffice. No email address.
Divide annual costs by twelve and give them a line. Car servicing and insurance renewals are not surprises; budgets that treat them as surprises fail in the month you can least afford it.
