Common Questions
How much should I save from each paycheck?
The 50/30/20 rule is a solid starting framework: 50% needs, 30% wants, 20% savings and debt repayment. Even saving 10% consistently builds significant wealth through compound interest.
Should I pay off debt or start investing?
Pay off high-interest debt (credit cards above 7%) first. For low-interest debt (mortgage, student loans under 5%), you can invest simultaneously since market returns historically exceed these rates.
What's the best savings account right now?
High-yield savings accounts at online banks offer 4-5% APY, far more than traditional banks. Look for FDIC insurance, no monthly fees, and easy transfers.
How do I start investing with no experience?
Start with a diversified index fund through a brokerage account or Roth IRA. Invest consistently regardless of market conditions (dollar-cost averaging). As you learn, diversify further.
Key Terms
Compound Interest
Interest calculated on both the principal and previously earned interest — "interest on interest." The engine behind long-term wealth building. $10,000 at 7% for 30 years grows to $76,122 through compounding. Starting early matters more than investing more later.
Dollar-Cost Averaging (DCA)
Investing a fixed amount at regular intervals regardless of market conditions. Buying more shares when prices are low and fewer when high, reducing the impact of volatility. Automatic 401(k) contributions are DCA by default. Removes emotion from investing decisions.
Index Fund
A mutual fund or ETF that tracks a market index (S&P 500, total market, international) by holding all or a representative sample of its components. Offers broad diversification at minimal cost. Most actively managed funds underperform index funds over 10+ year periods.
Exchange-Traded Fund (ETF)
A basket of securities (stocks, bonds, commodities) that trades on exchanges like a stock. ETFs offer diversification, low fees, and tax efficiency. Unlike mutual funds, ETFs trade throughout the day at market prices. Popular examples: VTI (total market), VOO (S&P 500), VXUS (international).
Roth IRA
A retirement account funded with after-tax dollars. Contributions can be withdrawn anytime tax-free. Earnings grow tax-free and withdrawals after age 59½ are tax-free. 2024 contribution limit: $7,000 ($8,000 if 50+). Income limits apply. The most powerful retirement tool for young earners.
