Financial experts recommend 3-6 months of essential expenses for most people. If you have an unstable income, are self-employed, or are the sole earner, aim for 6-12 months. Essential expenses include rent/mortgage, utilities, food, insurance, and minimum debt payments — not your entire monthly spending. Start with a $1,000 mini emergency fund, then build from there.

The 50/30/20 rule divides after-tax income into: 50% for needs (housing, food, insurance, minimum debt payments), 30% for wants (entertainment, dining out, hobbies), and 20% for savings/debt repayment. It's a solid starting framework, but adjust based on your situation — in high-cost cities, needs may take 60-70%, so reduce wants to compensate.

As of 2026, top high-yield savings accounts offer 4.0-5.0% APY, significantly higher than the national average of 0.45%. Online banks typically offer the highest rates because they have lower overhead costs. Look for accounts with no minimum balance requirements, no monthly fees, and FDIC insurance up to $250,000. Even at 4.5% APY, $10,000 earns $450/year vs. $45 at a traditional bank.

The average cost of 4 years at a public university is about $110,000 (in-state) and $230,000+ at private universities (2026 estimates including room and board). Using a 529 plan, if you start when your child is born and invest $350/month at 7% average return, you'll have approximately $150,000 by age 18. Starting at age 5 requires about $650/month for the same goal.

Net worth = Total Assets minus Total Liabilities. Assets include: savings accounts, investments, retirement accounts (401k, IRA), home equity, car value, and other property. Liabilities include: mortgage balance, student loans, auto loans, credit card debt, and any other debts. The average American household net worth is about $193,000 (median). Track your net worth quarterly to measure progress.
