A zero-based budget assigns available money to spending, savings, and priorities. It does not mean emptying your bank account.
Start with available money
Use reliable take-home income and money available for the period. Treat uncertain payments as available only when received. List obligations due before the next income date.
Assign savings too
Allocate amounts to essentials, debt minimums, planned purchases, savings, and flexible spending. A buffer can have its own job. The total assigned should equal the income being planned.
Use a small example
With a hypothetical $2,000, assign $1,400 to bills and essentials, $200 to annual costs, $250 to savings, and $150 to flexible spending. Some remains in the bank, but every dollar has a purpose.
Adjust intentionally
If one category needs more, decide where it can come from. Protect money already committed to a bill. Reconcile weekly and revise next month’s estimates using actual spending.
