Financial Glossary

1099

The family of IRS forms reporting income outside a regular paycheck — freelance pay, bank interest, dividends, brokerage proceeds. If you earned it without a W-2, a 1099 probably documented it.

401(k)

A retirement account offered by your employer. You contribute pre-tax dollars straight from your paycheck, the money grows tax-deferred, and many employers match part of your contribution — free money.

403(b)

The 401(k)'s twin for teachers, nurses, nonprofit and government workers. Same idea: pre-tax paycheck contributions, tax-deferred growth, often with an employer match.

529 Plan

A tax-advantaged account for education costs. Contributions grow tax-free and withdrawals for qualified education expenses — college, and now more — are tax-free too.

Amortization

Paying down a loan through fixed payments on a schedule, where early payments are mostly interest and later payments are mostly principal.

APR (Annual Percentage Rate)

The yearly cost of borrowing, expressed as a percentage. It includes the interest rate plus most lender fees, so it reflects the true price of a loan better than the rate alone.

APY (Annual Percentage Yield)

The real yearly return on savings, including compounding. Unlike a plain interest rate, APY tells you what $10,000 actually becomes after one year.

Asset Allocation

How you divide your portfolio between asset classes — stocks, bonds, cash, real estate. It is the single biggest driver of your long-term returns and risk.

Backdoor Roth IRA

A legal workaround for high earners locked out of Roth IRAs: contribute to a Traditional IRA (no income limit on contributions) and immediately convert it to Roth.

Bear Market

A sustained 20%+ drop from recent highs, driven by fear, recession, or crisis. Painful, normal, and historically always temporary.

Bonds

Loans you make to a government or company. They pay fixed interest on a schedule and return your principal at maturity — steadier and duller than stocks.

Brokerage Account

A standard taxable investing account with no contribution limits and no special tax treatment. Maximum flexibility, zero tax shelter.

Bull Market

A sustained rise in prices — commonly defined as a 20% climb from recent lows — driven by optimism, growth, and rising corporate profits.

Capital Gains

The profit when you sell an investment for more than you paid. Hold longer than a year and it is a long-term gain, taxed at lower rates than ordinary income.

Compound Interest

Interest calculated on both your original money and the interest it has already earned. It is the mechanism that turns steady, boring contributions into large sums over decades.

Credit Score

A 300–850 number summarizing how reliably you handle debt. Lenders use it to set your interest rates — a good score saves tens of thousands over a lifetime of borrowing.

Credit Utilization

The percentage of your available credit you are using. It is 30% of your credit score — the fastest-moving factor you control.

Debt Avalanche

Pay minimums on everything, then throw every extra dollar at the highest interest rate first. Mathematically the cheapest way out of debt.

Debt Snowball

Pay minimums on everything, then throw every extra dollar at the smallest balance first. Quick wins build momentum that math alone cannot.

Diversification

Spreading money across many investments so no single one can wreck you. It is the only free lunch in investing: less risk without necessarily less return.

Dividends

Cash payments companies send shareholders from profits, usually quarterly. It is getting paid to own the stock, on top of any price gains.

Dollar-Cost Averaging

Investing a fixed amount on a fixed schedule — every paycheck, every month — regardless of what the market is doing. You automatically buy more shares when prices are low.

Emergency Fund

Cash set aside for true emergencies — job loss, medical bills, car repairs — so a bad month does not become high-interest debt. It is insurance, not an investment.

Escrow

Money held by a neutral third party until conditions are met. In mortgages, part of each payment goes into escrow so property taxes and insurance get paid on time.

ETF (Exchange-Traded Fund)

A basket of investments — stocks, bonds, or both — that trades on an exchange like a single stock. Most ETFs are index funds you can buy and sell any time the market is open.

Expense Ratio

The annual fee a fund charges, expressed as a percentage of your investment. A 0.03% expense ratio costs you $3 per year on every $10,000 invested.

Fiduciary

An advisor legally required to act in your best interest — not just sell you something "suitable." If your advisor is not a fiduciary, their advice serves two masters.

FSA (Flexible Spending Account)

An employer account letting you pay for medical or dependent-care costs with pre-tax dollars. The catch: most of it is use-it-or-lose-it each year.

Home Equity

What your home is worth minus what you owe on it. It is usually most homeowners' largest asset — and their least liquid one.

HSA (Health Savings Account)

A savings account tied to a high-deductible health plan with triple tax benefits: pre-tax contributions, tax-free growth, and tax-free withdrawals for medical costs. No other account does all three.

Index Fund

A fund that simply owns everything in a market index — like the S&P 500 — instead of trying to pick winners. You get instant diversification at a near-zero fee.

Inflation

The gradual rise in prices that shrinks what each dollar buys. Cash sitting still is not standing still — it is losing purchasing power every year.

Mutual Fund

A pooled investment where many investors' money is combined and managed as one portfolio. You buy and sell once per day at the closing price, not during market hours.

Net Worth

Everything you own minus everything you owe. It is the single number that best measures financial health — more honest than income or lifestyle.

PMI (Private Mortgage Insurance)

Insurance you pay to protect the lender when your down payment is under 20%. It protects them, not you — and you can drop it once you hit 20% equity.

Rebalancing

Periodically selling what has grown and buying what has lagged to restore your target asset allocation. It forces you to sell high and buy low on a schedule.

REIT (Real Estate Investment Trust)

A company that owns income-producing real estate — apartments, offices, warehouses — and trades like a stock. By law it must pay out most of its income as dividends.

Risk Tolerance

How much portfolio pain you can stomach — and afford — without abandoning your plan. It is part psychology, part math, and most people overestimate it.

RMD (Required Minimum Distribution)

The amount the IRS forces you to withdraw each year from tax-deferred retirement accounts, starting at age 73. Skip it and the penalty is brutal.

Roth IRA

A retirement account you fund with after-tax dollars. The money grows tax-free and qualified withdrawals in retirement are tax-free — you pay the tax now so you never pay it again on that money.

Rule of 72

Divide 72 by your annual return to estimate how many years it takes money to double. The fastest mental math in finance.

Social Security

The federal program paying monthly benefits in retirement, disability, or to surviving family — funded by payroll taxes on your wages. For most retirees it is the foundation, not the whole house.

Standard Deduction

The no-questions-asked amount you subtract from income before tax is calculated. For 2026 it is $16,100 for single filers and $32,200 for married couples filing jointly.

Stocks

Partial ownership in a company. When the business grows and profits, your slice becomes worth more — and you share the risk if it does not.

Tax Bracket

The rate applied to each slice of your income. The U.S. system is marginal: only the dollars inside a bracket are taxed at that bracket's rate.

Tax-Loss Harvesting

Selling a losing investment in a taxable account to "harvest" the loss, which offsets gains and up to $3,000 of ordinary income per year. The portfolio stays invested; the tax bill shrinks.

Time Horizon

How long until you need the money. It is the most important input to every investing decision — more important than your opinions about the market.

Traditional IRA

A retirement account you fund yourself, independent of any employer. Contributions may be tax-deductible now, the money grows tax-deferred, and you pay income tax on withdrawals in retirement.

Volatility

How much and how fast prices swing. High volatility means bigger ups and bigger downs — the price of higher long-term returns.

W-2

The annual form your employer sends showing your wages and the taxes withheld. It is the official record of your earned income for the year.
