APR (Annual Percentage Rate)

The yearly cost of borrowing money, expressed as a percentage. APR includes both the interest rate and any fees, making it a more complete measure of loan cost than the interest rate alone. Credit cards, mortgages, and personal loans all express their cost as APR.

Asset

Anything you own that has monetary value or generates income. Assets include cash, investments, real estate, vehicles, and business interests. Building assets is the foundation of wealth — assets put money in your pocket.

Balance Transfer

Moving debt from one credit card to another, typically to take advantage of a lower interest rate (often 0% for an introductory period). A balance transfer can save hundreds or thousands in interest if you pay off the balance before the promotional rate expires.

Brokerage Account

A taxable investment account that lets you buy and sell stocks, ETFs, mutual funds, and bonds. Unlike retirement accounts, there are no contribution limits and no restrictions on withdrawals — but gains are subject to capital gains taxes.

Budget

A plan for how you will spend and save your money each month. A budget tells your dollars where to go instead of wondering where they went. Common budgeting methods include zero-based budgeting (every dollar has a job) and the 50/30/20 rule.

Cap Rate (Capitalization Rate)

A real estate metric that measures a rental property’s annual return, calculated as: Net Operating Income ÷ Property Value. A 7% cap rate means the property generates 7% of its value in annual income before debt service. Higher cap rates indicate higher potential returns but often higher risk.

Cash Flow

Money left over after all expenses are paid. In real estate: monthly rent minus mortgage, taxes, insurance, and maintenance. Positive cash flow means the property generates income; negative cash flow means you’re paying out of pocket each month.

Compound Interest

Interest calculated on both the principal and previously earned interest, causing growth to accelerate over time. Often called “the eighth wonder of the world.” $1,000 at 7% compounded annually becomes $7,612 in 30 years — without adding a single extra dollar.

Credit Score

A three-digit number (300–850) that measures your creditworthiness based on your payment history, credit utilization, length of credit history, credit mix, and new inquiries. A higher score unlocks lower interest rates and better loan terms.

Credit Utilization

The percentage of your available credit you’re currently using. If you have a $10,000 credit limit and a $3,000 balance, your utilization is 30%. Keeping utilization below 30% (ideally below 10%) is one of the fastest ways to improve your credit score.

Debt Avalanche Method

A debt payoff strategy where you make minimum payments on all debts and put every extra dollar toward the debt with the highest interest rate. When that debt is paid off, you roll that payment to the next highest-rate debt. The avalanche method minimizes total interest paid.

Debt Snowball Method

A debt payoff strategy where you make minimum payments on all debts and put every extra dollar toward the smallest balance first. When that debt is paid off, you roll that payment to the next smallest. The snowball method creates quick wins that build momentum.

Debt-to-Income Ratio (DTI)

Your monthly debt payments divided by your gross monthly income, expressed as a percentage. Lenders use DTI to evaluate loan eligibility. A DTI below 36% is generally considered healthy; above 43% makes it difficult to qualify for most mortgages.

Dividend

A portion of a company’s profits paid to shareholders, typically quarterly. Dividend-paying stocks and ETFs provide regular income in addition to potential share price appreciation. Dividend investing is popular for building passive income streams.

Emergency Fund

A cash reserve set aside specifically for unexpected expenses — medical bills, car repairs, job loss. Financial experts recommend 3–6 months of living expenses in a high-yield savings account. An emergency fund prevents debt from derailing your financial plan.

ETF (Exchange-Traded Fund)

A basket of securities (stocks, bonds, or other assets) that trades on an exchange like a single stock. ETFs offer instant diversification, low costs, and flexibility. A total market ETF like VTI gives you exposure to thousands of companies with one purchase.

Expense Ratio

The annual fee an ETF or mutual fund charges, expressed as a percentage of your investment. A 0.03% expense ratio on a $10,000 investment costs $3/year. Lower is always better — high expense ratios compound into significant losses over decades.

High-Yield Savings Account (HYSA)

A savings account that pays a significantly higher interest rate than a traditional bank savings account — often 4–5% APY vs. the national average of 0.01–0.06%. HYSAs are ideal for emergency funds and short-term savings goals.

Index Fund

A fund designed to track a specific market index (like the S&P 500) by holding the same securities in the same proportions. Index funds are passively managed, which means lower fees and historically better long-term performance than most actively managed funds.

Liability

A debt or financial obligation — money you owe to someone else. Liabilities include mortgages, car loans, student loans, and credit card balances. Net worth = Assets − Liabilities. Reducing liabilities builds wealth.

Net Worth

The total value of everything you own (assets) minus everything you owe (liabilities). Net worth is the most accurate snapshot of your financial health. Tracking net worth monthly shows whether your financial plan is working over time.

REIT (Real Estate Investment Trust)

A company that owns income-producing real estate and trades on stock exchanges like a stock. REITs let you invest in real estate without buying property directly. They are required by law to pay at least 90% of taxable income as dividends to shareholders.

Roth IRA

An individual retirement account funded with after-tax dollars. Your money grows tax-free and qualified withdrawals in retirement are completely tax-free. Roth IRAs have annual contribution limits ($7,000 in 2025; $8,000 if 50+) and income phase-out thresholds.

401(k)

A tax-advantaged retirement savings plan offered by employers. Traditional 401(k) contributions reduce your taxable income now; Roth 401(k) contributions are after-tax with tax-free growth. Many employers match contributions — always contribute at least enough to get the full match (it’s free money).

Sinking Fund

Money set aside in advance for a planned future expense — car replacement, vacation, home repair, holiday gifts. Sinking funds prevent predictable expenses from feeling like emergencies. You give each fund a name, a target amount, and a monthly contribution.
