Zero-Based Budgeting: Giving Every Dollar a Job
Income minus allocations equals zero. Not zero in the account — zero unassigned.

What to take away
- Every dollar gets a named job before the month starts.
- Saving is a category, not a leftover.
- Suits variable income better than percentage-based budgets.
List expected income for the month, then allocate it downward through categories until nothing remains unassigned. Saving and investing are categories in the list, not whatever survives at the end.
Why it exposes more
Percentage budgets tell you the shape of your spending. Zero-based budgeting forces a decision about each dollar, which surfaces the unnamed drift — the $300 a month that was not any particular thing.
With irregular income
Budget the previous month’s actual income rather than forecasting. You are always allocating money you already have, which removes the guesswork entirely.
Include a category called “unassigned buffer” of $100–$200. Without it, the first unexpected expense breaks the whole month and people abandon the method.
Common questions
No. Allocating to savings is an assignment. Zero refers to unassigned dollars, not to the account balance.
