Banking: checking and savings accounts

This lesson focuses on banking: checking and savings accounts. Interdisciplinary approaches reveal connections that single-subject study might miss.

Financial literacy is the ability to understand and manage personal finances. Income: money you earn (wages, salary, investment returns). Gross income is before deductions; net income (take-home pay) is after income taxes, Social Security, and Medicare withholding. Budgeting: tracking income and expenses to ensure you spend less than you earn. The 50/30/20 rule: ~50% needs (housing, food), ~30% wants (entertainment), ~20% saving/debt repayment. Compound interest is the "eighth wonder of the world"—interest earned on principal plus previously earned interest. Example: $1,000 at 7% annual return grows to ~$7,600 in 30 years without adding a penny. Credit score (300–850) reflects borrowing history and determines interest rates offered. Debt management: high-interest debt (credit cards, ~20%) should be paid first. Key principle: make money work for you through saving and investing, not just working for money.

As you engage with this material, consider both the theoretical foundations and practical applications. Think critically about how this concept builds on prior knowledge and where you might apply it beyond the classroom.

Challenge yourself to go beyond memorization—seek to understand the "why" behind the processes and principles.
