What budgeting method actually works?

The 50/30/20 rule is the simplest starting point: 50% needs, 30% wants, 20% savings. Zero-based budgeting (every dollar assigned a job) works best for people with irregular income. Envelope/cash systems help overspenders physically feel the spending. The "best" method is the one you'll actually follow for more than two months. Start simple and add complexity only if needed.
