30% Rule: A widely used financial guideline suggesting that an housing expenses—including rent/mortgage, utilities, taxes, and insurance—should not exceed 30% of a household’s gross monthly income.

401(k): Employer-sponsored retirement plan where you contribute pre-tax money; many employers match contributions (free money!).

403(b): A retirement savings plan similar to a 401(k), but offered mainly to employees of public schools, nonprofits, hospitals, and certain tax-exempt organizations. Contributions are often pre-tax (reducing your current taxes), and many employers match a portion—great for building long-term savings with tax advantages.

457(b): A retirement savings plan for state and local government employees and some nonprofit workers. Similar to a 401(k) — you contribute pre-tax money that grows tax-deferred until withdrawal.

APR (Annual Percentage Rate): The yearly cost of borrowing, including interest and some fees—helps compare loans/credit cards.

APY (Annual Percentage Yield): The real yearly return on savings/investments, including compound interest—higher is better for savers.

Asset: Anything you own that has financial value, such as cash, a car, a house, stocks, or retirement accounts.

Bond: A loan you make to a company or government; they pay back principal plus interest over time (generally safer than stocks).

Budget: A plan that tracks your income and expenses to decide how to allocate money each month (helps prevent overspending).

Compound Interest: Interest earned on both the original amount and previously earned interest—often called “interest on interest.” It accelerates growth over time.

Covered Calls: A strategy where you own shares of a stock and sell (write) a call option against those shares. You collect money upfront from the buyer. If the stock doesn’t rise much, you keep both the shares and the money you were paid. It’s one of the most popular ways to earn extra income from stocks you already own.

Credit: The ability to borrow money now and pay later, based on trust in your repayment history.

Credit Report: A detailed record of your borrowing history, including accounts, payments, and debts—used to calculate your credit score.

Credit Score: A three-digit number (usually 300–850) that shows lenders how reliably you manage credit. Higher scores mean better loan terms.

Debt: Money borrowed that must be repaid, usually with interest (good debt like a mortgage can build wealth; bad debt like high-interest credit cards drains it).

Diversification: Spreading investments across different types (stocks, bonds, etc.) to reduce risk—if one drops, others may hold steady.

Dividend: A portion of a company’s profit paid to shareholders. Public companies that pay dividends usually do so on a fixed schedule, although they can issue them at any time. Unscheduled dividend payments are known as special dividends or extra dividends.

Emergency Fund: Money set aside in a safe, accessible account (ideally 3–6 months of living expenses) for unexpected events like job loss or repairs.

Emergency Fund: A dedicated cash reserve (typically in a high-yield savings account) set aside for unexpected expenses or income disruptions, such as medical bills, car repairs, or job loss. Aim for 3–6 months (or more) of essential living expenses to avoid debt in emergencies.

Employer Match: Free money your employer adds to your retirement account when you contribute. For example, they might match 50% of what you put in up to a certain percentage of your pay. It’s one of the best deals in personal finance.

Employer Sponsored Plans (ESP): Retirement or savings plans offered by your employer. Common examples include 401(k), 403(b), and 457(b) plans. Many include tax advantages and sometimes free matching money from the employer.

Envelope Method: A budgeting system where you divide your income into categories (e.g., groceries, entertainment) and allocate a fixed amount of cash (or digital “envelopes”) to each. Once the money in an envelope is gone, spending in that category stops until the next budget period—helping control impulse buys and stick to a plan.

ETF (Exchange-Traded Fund): A basket of investments (like stocks) traded on stock exchanges throughout the day, often low-cost.

Excise Tax: An indirect, per-unit or percentage-based tax imposed on specific goods, services, or activities—such as fuel, tobacco, alcohol, and air travel—rather than on general sales.
Often included in the product’s price, these taxes are typically levied to reduce consumption of certain items (sin taxes) or to fund related public services.

Expenses: Money you spend on needs (housing, food, utilities) and wants (entertainment, dining out).

FDIC Insured: Government protection that guarantees your money in a bank or High-Yield Savings Account (HYSA) is safe — even if the bank fails. The FDIC (Federal Deposit Insurance Corporation) will insure up to $250,000 per person, per bank. So if your bank goes under, you get your money back (usually within a few days). This is why smart snowball builders only keep cash in FDIC-insured accounts — your principal is protected while you earn interest.

FICA Tax: FICA tax stands for Federal Insurance Contributions Act tax. It’s a payroll tax that funds Social Security and Medicare programs.

Components (employee share):
• Social Security: 6.2% on wages up to the wage base ($184,500 in 2026).
• Medicare: 1.45% on all wages (no cap).

Total employee FICA rate: 7.65% (employer matches another 7.65%, for 15.3% combined).

Self-employed pay both shares (15.3%, with some deductions).
Additional Medicare tax (0.9%) applies for high earners (e.g., over $200,000 single).
Unlike regular income tax, FICA is flat-rate and applies only to earned wages (not investment income).

Financial Independence (FI): A state where you have enough savings, investments, or passive income to cover your living expenses indefinitely without needing to work for money. It provides the freedom to choose how you spend your time, even if you continue working by choice. Often linked to the FIRE movement (Financial Independence, Retire Early).

FIRE (Financial Independence, Retire Early): A lifestyle and financial movement where people aim to save and invest aggressively (often 50%+ of income) to achieve financial independence and retire much earlier than traditional ages (e.g., in their 30s, 40s, or 50s). The goal is to build enough assets to cover living expenses without needing a job.

Fixed Expenses: Costs that stay the same each month, like rent/mortgage, car payments, or insurance.

Frugality: The conscious, intentional practice of being economical with resources—money, time, and food—to avoid waste and increase savings. It involves prioritizing quality over quantity, DIY skills, and mindful spending to foster financial independence and sustainability. Benefits include reduced financial stress, greater security, and a simpler, often more fulfilling lifestyle.

Gross Income: Your total income before taxes or deductions are taken out.

High Yield Savings Account: A type of savings account that pays a significantly higher interest rate (expressed as APY, or annual percentage yield) than traditional savings accounts, often 10–20 times (or more) above the national average for standard accounts. This allows your money to grow faster through compound interest while remaining safe (typically FDIC-insured up to $250,000), liquid (easy access to funds), and low-risk—ideal for emergency funds or short-term savings.

High Yield Savings Account (HYSA): A savings account that pays a much higher interest rate (APY) than traditional bank savings accounts — often 10x to 20x higher. Your money grows faster through compound interest while staying safe (FDIC-insured up to $250,000), liquid, and low-risk. Perfect for your emergency fund or short-term cash that you don’t want sitting in a 0.01% account doing nothing.

Income: Money you receive, such as salary, wages, bonuses, side hustle earnings, interest, dividends, or government benefits.

Income Tax: Income tax is a tax levied on the income earned by individuals or businesses during a tax year. In the U.S., the federal income tax is progressive (higher rates on higher income levels) and applies to wages, salaries, tips, interest, dividends, rental income, business profits, and more (after deductions and exemptions). It’s calculated on taxable income (gross income minus allowable deductions). States often have their own income taxes too. The IRS collects it via withholding from paychecks or quarterly estimated payments.

Index Fund: A simple, low-cost way to own a tiny piece of hundreds or thousands of stocks all at once. Instead of picking individual companies, an index fund just copies a market index (like the S&P 500 or total U.S. stock market). You get broad diversification, very low fees (often 0.03–0.05%), and the long-term growth of the overall market — without needing to be a stock-picking genius. This is one of the most popular “set it and forget it” tools for building a snowball.

Inflation: The general rise in prices over time, which reduces purchasing power (e.g., $100 today buys less in 10 years).

Inflation: The steady rise in the cost of goods and services over time. It quietly eats away at your purchasing power — meaning a dollar today buys less in the future than it does right now. This is why simply keeping cash in a low-interest account can actually make you poorer over the long run.

Interest: The cost of borrowing money (you pay it on loans) or the reward for saving/lending (you earn it on savings/investments).

Investment Policy Statement (IPS): A written document outlining your investment goals, risk tolerance, time horizon, asset allocation preferences, and guidelines for managing your portfolio. It serves as a roadmap for you (or your advisor) to make disciplined, consistent decisions and avoid emotional reactions during market volatility.

IRA (Individual Retirement Account): Personal retirement account you open yourself; traditional (tax-deferred) or Roth (tax-free growth).

Liability: Something you owe, like a loan, credit card balance, mortgage, or unpaid bill.

Mutual Fund: A pool of money from many investors managed by professionals to buy stocks, bonds, or other assets.

Net Income: Your income after taxes, insurance, retirement contributions, and other deductions are subtracted.

Net Worth: Your total assets minus your total liabilities. A snapshot of your overall financial health.

Option Trading: Buying and selling contracts that give you the right (but not the obligation) to buy or sell a stock at a specific price by a certain date. Options can be used to make bets on price movement, generate income, or protect your investments.

Ordinary Income: Refers to most types of earned or unearned income taxed at regular federal income tax rates, including wages, salaries, tips, business income, and—importantly—interest earned from savings accounts (including high-yield ones). The interest you earn on a HYSA is reported to the IRS (via Form 1099-INT if over $10) and taxed as ordinary income in the year it’s credited, even if you don’t withdraw it. Only the interest is taxed—not your principal deposits.

Personal Property Tax: An annual tax levied by local governments on movable, tangible assets like vehicles, boats, and business equipment. Unlike real estate tax, it applies to items that can be moved, with rates typically based on the asset’s assessed value. It is often referred to as tangible property tax, vehicle tax, or business personal property tax.

Puts: A type of options contract that gives the buyer the right to sell a stock at a specific price by a certain date. Most people buy puts when they think a stock price will go down (to make money from the drop) or to protect their portfolio from falling prices.

Real Property Tax: An ad valorem (based on value) tax levied by local governments on real estate, including land and buildings. As the primary revenue source for municipalities and counties, these taxes fund essential public services like schools, police, fire departments, road maintenance, and libraries.

Retirement Account: Special accounts (e.g., 401(k), IRA) for long-term savings, often with tax advantages to encourage saving for retirement.

Rule of 72: A simple way to estimate how long it takes for an investment to double in value at a fixed annual return: divide 72 by the interest rate (e.g., 72 ÷ 8% = 9 years). It’s a quick mental math tool for understanding compound growth and planning long-term savings or investments.

S&P 500: A stock market index that tracks the performance of 500 of the largest U.S. companies. It is widely used as a benchmark for how the overall U.S. stock market is doing.

Sales Tax: A consumption tax imposed by governments on the sale of goods and services, typically calculated as a percentage of the purchase price and collected by retailers from consumers at the point of purchase.

Savings: Money set aside from income instead of spending it, often in a savings account or other low-risk place.

Savings Rate: The percentage of your after-tax income that you save rather than spend. Calculated as (savings ÷ disposable income) × 100. A higher savings rate accelerates wealth-building and is a key metric in achieving financial independence.

SEP IRA (Simplified Employee Pension IRA): Simplified Employee Pension IRA. A retirement plan mainly for self-employed people and small business owners. Only the employer (you, if self-employed) makes contributions — easy to set up with high contribution limits.

SIMPLE IRA: Savings Incentive Match Plan for Employees IRA. A retirement plan for small businesses with 100 or fewer employees. Employees can contribute from their paycheck, and the employer must either match contributions or make a small contribution for everyone.

Solo 401k: Also called a One-Participant 401(k) or Individual 401(k). A retirement plan for self-employed individuals or business owners with no employees. You can contribute as both the employee and the employer, allowing very high total contributions.

Stock: A small ownership share in a company; value can rise/fall based on company performance.

Tax: A tax is a mandatory financial charge or contribution imposed by a government (federal, state, or local) on individuals, businesses, or other entities to fund public services, infrastructure, defense, social programs, etc. It’s not a voluntary payment—failure to pay can result in penalties. Taxes come in many forms (income, sales, property, payroll, etc.), and the U.S. system includes federal taxes administered by the IRS, plus state/local variations.

Tax Bracket: A range of income taxed at a specific, progressive rate in a graduated tax system. Instead of taxing all income at one rate, the U.S. system applies higher rates only to the portion of income that exceeds certain thresholds, meaning you pay different rates on different chunks of your earnings.

Tax Deduction: An expense or amount that you subtract from your gross income to lower your taxable income, which reduces the amount of tax you owe. Common examples include the standard deduction (a fixed amount everyone can claim) or itemized deductions (like mortgage interest, charitable donations, or medical expenses if they exceed certain thresholds). Deductions help keep more of your money in your pocket by shrinking what the IRS taxes.

Taxable Income: The portion of your income subject to taxes after deductions/exemptions.

TSP (Thrift Savings Plan): A low-cost retirement savings plan for federal government employees and uniformed service members (like military). It works like a 401(k) with automatic contributions, potential employer matching, and simple investment options (funds tracking stocks, bonds, etc.)—one of the most efficient retirement vehicles available.

Variable Expenses: Costs that change month to month, like groceries, gas, or entertainment.

VFIAX (Vanguard 500 Index Fund Admiral Shares): Vanguard 500 Index Fund Admiral Shares. A mutual fund that tries to match the performance of the S&P 500. It is a low-cost way to invest in the 500 largest U.S. companies.

VOO: Vanguard S&P 500 ETF. An exchange-traded fund that tracks the S&P 500 index. Like VFIAX but trades like a stock throughout the day and usually has a slightly lower expense ratio.
