Should I budget with gross or net income?

Always budget with net (after-tax) income. Gross income is misleading since taxes, FICA, and pre-tax deductions are taken out before you receive your paycheck.

Paycheck Budget Breakdown

Q: What is the 50/30/20 budget rule?

The 50/30/20 rule allocates 50% of after-tax income to needs (housing, food, transport), 30% to wants (dining out, entertainment), and 20% to savings/debt repayment.

Q: How much should I budget for housing?

Financial advisors generally recommend housing costs (rent or mortgage, plus utilities) should not exceed 30% of your gross monthly income, or about 35-40% of after-tax income.

Q: What percentage should go to savings?

At minimum, aim for 10-15% of after-tax income toward savings. The 20% bucket in the 50/30/20 rule covers savings and debt payoff. Emergency fund target: 3-6 months of expenses.

Take your after-tax paycheck and split it into practical percentage buckets. Whether you follow the 50/30/20 rule or create a custom allocation, this tool shows you exactly how much to put toward housing, savings, essentials, and lifestyle spending.
