Monthly Budget Details
50/30/20 Budget Breakdown
How this calculation works
The 50/30/20 rule is a simple framework, not a one-size-fits-all solution. If your housing costs 60% of income in a high-cost area, that's okay — adjust the other categories to compensate.
The key is to make the plan work for your actual life, not a textbook ideal. Many people find that tracking expenses for 1-2 months reveals patterns they didn't expect.
