How to Analyze Monthly Fixed Expenses
Fixed expenses are recurring costs that stay roughly constant each month. The 50/30/20 rule recommends keeping all essential fixed costs at or below 50% of monthly net income. If this percentage exceeds 60%, building an emergency fund or saving becomes very difficult.
The biggest wins in reducing fixed costs come from housing and subscriptions. If rent exceeds 30% of income, consider a roommate, relocating, or negotiating. For subscriptions, a monthly audit of your bank statement often reveals services you have forgotten about and no longer use.
50/30/20 Budget Rule Guide
| Category | Target % | For $5,000/mo income |
|---|---|---|
| Fixed needs | 50% | Up to $2,500 |
| Flexible wants | 30% | Up to $1,500 |
| Savings / debt | 20% | $1,000+ |
