🏛️ Section 1: Banking, Liquidity, and Cash Management
This section covers how you move, save, and protect your day-to-day money.
APY (Annual Percentage Yield): This is the "real" interest rate you earn on your savings. It includes Compounding, which means it accounts for the interest you earn on your interest. In 2026, always look for an APY above 4.5%.
ACH (Automated Clearing House): The electronic network used for US bank-to-bank transfers. This is how your paycheck is "Direct Deposited" and how you pay most bills online.
CD (Certificate of Deposit): A "savings lockbox." You give the bank your money for a fixed time (e.g., 1 year) in exchange for a higher interest rate than a regular savings account. If you take the money out early, you pay a penalty.
Checking Account: Your "working" account. It’s for daily spending. It usually pays 0% interest.
HYSA (High-Yield Savings Account): A savings account, usually at an online bank, that pays 10x to 20x more interest than a traditional "Big Bank" (like Chase or Bank of America).
Joint Account: An account owned by two people (usually spouses). Both have 100% access to the money.
Liquid Assets: Money you can touch immediately (Cash, Checking, Savings). A house is not a liquid asset because it takes months to sell.
Overdraft Protection: A service where the bank covers a transaction if you have $0 in your account. Warning: Banks often charge $30+ per transaction for this "favor." In 2026, it is better to disable this and have the card simply decline.
Routing Number: A 9-digit code that identifies your specific bank. You need this + your Account Number to set up direct deposit.
💳 Section 2: Credit, Debt, and Lending
Understanding these terms determines how much you pay for your "life" (houses, cars, and lifestyle).
Amortization: The schedule of your loan payments. In a 30-year mortgage, the first 10 years of payments go mostly to interest. Only in the later years do you truly start "owning" the house (paying the principal).
APR (Annual Percentage Rate): The total cost of a loan, including interest and fees. The Golden Rule: Always compare APR, not just the "Interest Rate," when shopping for a car or house.
Credit Utilization Ratio: The amount of credit you are using divided by your total limit. If you have a $1,000 limit and spend $300, your utilization is 30%. Keep this under 10% for the highest credit score.
Debt-to-Income (DTI) Ratio: Your monthly debt payments divided by your monthly gross income. Banks want to see this below 36% before they give you a mortgage.
FICO Score: The most common credit scoring model (300 to 850). It is calculated based on payment history (35%), amounts owed (30%), length of credit history (15%), new credit (10%), and credit mix (10%).
Hard Inquiry: When a lender checks your credit to give you a loan. This temporarily drops your score by a few points.
Principal: The actual amount you borrowed. If you take a $10,000 loan, the principal is $10,000. The interest is the "rent" you pay on that money.
Secured Credit Card: A credit card for people with no credit. You give the bank a $500 deposit, and they give you a $500 limit. It’s a "training wheels" card to build your score.
Variable Interest Rate: An interest rate that can change (up or down) based on the economy. Fixed rates stay the same forever.
📈 Section 3: Investing and Wealth Building
This is the language of the stock market and retirement.
401(k) / 403(b): Retirement accounts offered by employers. The money is taken out of your paycheck before you pay taxes.
Bear Market: When the stock market drops by 20% or more.
Bull Market: When the stock market is rising.
Capital Gains: The profit you make when you sell an investment. If you buy a stock for $10 and sell it for $15, your capital gain is $5.
Dividend: A portion of a company's profit paid out to stockholders. Think of it as a "reward" for owning the stock.
ETF (Exchange Traded Fund): A collection of stocks or bonds that you can buy and sell like a single stock. It is the most efficient way for beginners to invest in 2026.
Expense Ratio: The annual fee you pay to own a fund. If a fund has a 1% expense ratio, they take $1 out of every $100 you have every year. Look for "Low Cost" funds with ratios below 0.10%.
Index Fund: A type of fund that simply tracks a list of companies (like the S&P 500). It doesn't try to "beat" the market; it just follows it. This is the most recommended investment for long-term wealth.
Roth IRA: An individual retirement account where you pay taxes on the money now, but the money grows and comes out 100% tax-free after age 59.5.
S&P 500: An index of the 500 largest companies in the US. It is the "thermometer" for the US economy.
Volatility: How much a stock price jumps up and down. High volatility means high risk (and potentially high reward).
📑 Section 4: Taxes and Government Regulations
The rules of the IRS (Internal Revenue Service) in 2026.
AGI (Adjusted Gross Income): Your total income minus specific deductions (like student loan interest). This number is used to see if you qualify for many government credits.
Deduction: An amount you subtract from your income so you pay less tax. (e.g., if you earn $50k and have a $10k deduction, you only pay tax on $40k).
FICA: Federal Insurance Contributions Act. These are the taxes taken out of your check to pay for Social Security and Medicare.
Standard Deduction: A fixed dollar amount that the government lets everyone take off their income automatically. In 2026, it is approximately $15,500 for single filers.
Tax Credit: Better than a deduction. A credit reduces your tax bill dollar-for-dollar. A $1,000 credit means you pay exactly $1,000 less in taxes.
Tax Bracket: The percentage you pay in tax. The US uses a "Progressive" system, meaning you only pay the higher percentage on the money earned within that bracket.
W-2: The form your employer gives you in January showing how much you earned and how much tax you already paid.
W-4: The form you fill out when you start a job to tell the government how much tax to take out of your check.
🛡️ Section 5: Insurance and Risk Management
How to protect yourself from financial ruin.
Beneficiary: The person who gets your money or assets if you die. You must name these on your bank and investment accounts!
Coinsurance: Your share of a medical bill (e.g., you pay 20%, insurance pays 80%).
Deductible: The amount you pay out-of-pocket before the insurance company pays a penny.
HSA (Health Savings Account): A special account for people with high-deductible health plans. The money goes in tax-free, grows tax-free, and comes out tax-free for medical bills.
Out-of-Pocket Maximum: The most you will have to pay for medical care in a single year. This is your "worst-case scenario" number.
Premium: The monthly fee you pay to have insurance.
Term Life Insurance: Insurance that pays your family a set amount if you die within a certain time (e.g., 20 years). It is cheap and essential if you have children.
