Budgeting Methods Comparison
| Method | How it works | Best for | Watch out for |
|---|---|---|---|
| 50/30/20 | Splits take-home income into needs, wants, and saving/debt goals. | People who want a simple starting framework. | Percentages may not fit high-cost areas or unusual income. |
| Zero-based budget | Assigns every dollar of expected income a job before the month starts. | People who want detailed control. | Requires more regular maintenance. |
| Pay yourself first | Moves savings toward goals before discretionary spending. | People focused on building savings consistency. | Still requires enough cash for bills and essentials. |
| Envelope/category method | Sets spending limits by category. | People who overspend in a few predictable areas. | Can feel restrictive if categories are unrealistic. |
