Zero Based Budgeting Steps For Irregular Income
📑 In this guide
The Core Formula
Every $ assigned: income − expenses − savings = 0. For irregular, use lowest-month base.
All figures use 2026 published baselines: federal standard deduction $16,100 (single) / $32,200 (married filing jointly), Social Security wage base $184,500, and the FLSA 40-hour workweek (2,080 hours/year). For state-specific rates, see the State Money Data hub.
Step-by-Step: Running the Math Yourself
- List all categories to zero.
- Use prior lowest month as base.
- Buffer surplus months.
- Assign every dollar.
$3,000 mo: rent $1,100 + food $500 + save $400 + rest assigned = 0.
