Try it freeThe 50/30/20 rule is a simple budgeting framework: split your after-tax income into 50% needs, 30% wants, and 20% savings and debt repayment. It's popular because it's easy to remember and flexible enough to fit almost any income.
The essentials you'd struggle to live without: housing, groceries, utilities, transportation, insurance, and minimum debt payments. If your needs creep above half your income, that's the first signal to look at bigger fixed costs.
The lifestyle spending that makes life enjoyable but isn't strictly required: dining out, streaming, travel, hobbies, and shopping. This is usually where the easiest adjustments hide — and where seeing line-item receipts makes the biggest difference.
Building your emergency fund, investing for the future, and paying down debt faster than the minimum. Automating this slice — moving it the day you're paid — is the single most effective budgeting habit.
Knowing your targets is easy. Keeping the plan current is the work. Cosmic Budget tracks your category budgets as transactions sync, so you can see which parts of the plan need attention without rebuilding a spreadsheet.
