Home › Glossary › Zero-Based Budgeting
Zero-based budgeting is a method where every dollar of income gets assigned a specific job before the month begins. Income minus all assignments equals zero.
The principle is that money expands to fill available space. By pre-assigning every dollar a job, the budgeter avoids 'mystery spending' on undefined categories. Popularized by Dave Ramsey and the YNAB (You Need A Budget) app.
A budgeter with $4,500 monthly take-home assigns: $1,500 rent, $400 utilities, $600 groceries, $300 transport, $250 insurance, $200 phone/internet, $400 minimum debt payments, $300 extra debt payment, $200 entertainment, $250 personal/clothing, $100 misc, $0 left = budget zeroed. Every dollar has a purpose before the month begins.
Compared to the 50/30/20 rule: The 50/30/20 rule allocates by percentage to three buckets (needs/wants/savings) and is simpler but less granular. Zero-based budgeting is more rigorous but requires more discipline. Compared to envelope budgeting: Envelope is conceptually similar but typically uses physical or digital category 'envelopes' with no spillover.
