What is the 50/30/20 budgeting rule?

The 50/30/20 rule divides take-home income into three buckets: 50% for needs (rent, groceries, utilities), 30% for wants (dining, entertainment, subscriptions), and 20% for savings and debt repayment beyond minimums. It's a simple framework to ensure you're saving consistently.

How do I calculate my net worth?

Net worth = Total Assets - Total Liabilities. Assets include: cash, investments, real estate equity, vehicles, and other valuable property. Liabilities include: mortgage balance, car loans, student loans, credit card balances, and other debts.

What is ROI and how is it calculated?

ROI (Return on Investment) = (Gain - Cost) / Cost × 100%. For example, investing $1,000 and getting back $1,500 gives an ROI of 50%. For time-adjusted comparisons, use annualized ROI = [(Final/Initial)^(1/years) - 1] × 100%.

How do I calculate take-home pay?

Net (take-home) pay = Gross salary - Federal income tax - State income tax - FICA (Social Security 6.2% + Medicare 1.45%) - Pre-tax deductions (401k, HSA) - Post-tax deductions (benefits, garnishments). The exact amount depends on filing status and deduction elections.
