401(k): A 401(k) is a tax-advantaged, employer-sponsored retirement savings plan. It allows employees to divert a portion of their pre-tax salary into a private investment account, where the funds can grow tax-deferred until withdrawal.
403(b): A retirement plan similar to a 401(k) but available to employees of schools, universities, hospitals, and other non-profit organizations.
4% Rule: A retirement planning guideline asserting that an investor can safely withdraw 4% of their total investment portfolio’s starting value during the first year of retirement, followed by annual adjustments for inflation, with a high probability of maintaining a sufficient account balance to sustain a thirty-year retirement period.

A

Amortization: Amortization is the process of gradually reducing a debt or the value of an intangible asset over a predetermined timeframe through regularly scheduled payments of both principal and interest. In the context of a loan, payments are structured so that the interest expense decreases over time while the principal repayment increases, eventually resulting in a zero balance at the end of the term.
Asset Allocation: The strategy of dividing your investments among different asset types (stocks, bonds, cash) based on your goals and risk tolerance. A common starter allocation is 80% stocks / 20% bonds.

B

Backdoor Roth IRA: A strategy for high-income earners to contribute to a Roth IRA indirectly: contribute to a Traditional IRA, then immediately convert it to a Roth. Subject to pro-rata tax rules if you have existing pre-tax IRA balances.
Bond: A loan you make to a government or corporation. In return, they pay you interest (the coupon) and return your principal at maturity. Bonds are generally lower-risk than stocks but with lower expected returns.
Budget: A plan that tracks your income and categorizes your spending. Creating a budget helps you understand where money goes and identify areas to cut back or redirect toward savings.

C

Capital Gains: The profit from selling an investment for more than you paid for it. Short-term gains (held < 1 year) are taxed as ordinary income; long-term gains (held ≥ 1 year) get preferential tax rates (0%, 15%, or 20%).
Coast FIRE: A financial milestone where you've saved enough that your current investments will grow to your retirement goal without any additional contributions. You can then "coast" and focus on living expenses.
Compound Interest: The interest you earn on your interest. If you invest $1,000 at 7% annual returns for 10 years, you don't just earn $700 — compound returns turn it into ~$1,967. The longer you invest, the more powerful it becomes.
Cost Basis: The original price you paid for an investment. If you bought 10 shares at $50 each (cost basis = $500) and sell at $60 each ($600 revenue), your capital gain is $100.
Credit Score: A three-digit number (300–850) that summarizes your credit history. Lenders use it to decide whether to lend you money and what interest rate to charge. Payment history, credit utilization, and length of credit history are major factors.

D

Debt Avalanche: A debt payoff strategy where you pay the minimum on all debts, then put extra money toward the debt with the highest interest rate. Mathematically optimal because it minimizes total interest paid.
Debt Snowball: A debt payoff strategy where you pay the minimum on all debts, then put extra money toward the smallest debt (by balance). Less mathematically optimal than avalanche, but the quick wins can provide motivation.
Diversification: Spreading your investments across different types of securities, sectors, and geographies to reduce risk. If one investment underperforms, others may offset the loss.
Dollar-Cost Averaging (DCA): Investing a fixed amount of money at regular intervals (e.g., $500/month) regardless of market conditions. Removes the stress of timing the market and prevents investing everything at a peak.

E

Emergency Fund: Money set aside (typically 3–6 months of expenses) in a liquid, easily accessible account for unexpected events: job loss, medical bills, home repairs. Prevents you from going into debt.
Employee Stock Purchase Plan (ESPP): A program that allows employees to purchase company stock at a discount (often 10–15% below market price). The discount is taxable income, but you can realize gains if the stock appreciates.
Estate Planning: The process of documenting how your assets should be distributed after you die, typically through a will, trust, or beneficiary designations. Also covers powers of attorney and healthcare directives.
ETF (Exchange-Traded Fund): A basket of securities (stocks or bonds) traded on an exchange like a stock. ETFs are liquid, have lower expense ratios than mutual funds, and are tax-efficient.
Expense Ratio: The annual fee (as a percentage) a fund charges for management. A fund charging 1% on a $10,000 investment costs $100/year. Index funds typically charge 0.03–0.10%; actively managed funds charge 0.5–2% or more.

F

FIRE (Financial Independence, Retire Early): A movement focused on saving aggressively (often 50%+ of income), investing wisely, and retiring decades earlier than the traditional retirement age. Success depends on reaching a number where your investments cover your expenses.
FI Number (Financial Independence Number): The total amount of invested assets you need to cover your annual spending indefinitely using the 4% rule. Example: if you spend $40,000/year, your FI number is $1 million.
Fixed-Rate Mortgage: A mortgage where the interest rate stays the same for the entire loan term (typically 15, 20, or 30 years). Your monthly payment is predictable and doesn't change with market rates.

H

HSA (Health Savings Account): A tax-advantaged savings account paired with a high-deductible health insurance plan. Contributions are tax-deductible, growth is tax-free, and withdrawals for qualified medical expenses are tax-free. Unused funds roll over forever.

I

Index Fund: A fund that holds all or most of the securities in a market index (e.g., the S&P 500) in the same proportions, aiming to match that index's performance. Low fees and historically outperform most actively managed funds.
Inflation: The rate at which the general level of prices for goods and services rises over time. If inflation is 3%, something that costs $100 today will cost $103 next year. Reduces your purchasing power.
Interest Rate: The percentage of principal you pay (on a loan) or earn (on savings) per year. A 5% interest rate on a $10,000 loan costs $500/year. Higher rates are better for savings, worse for borrowing.
IRA (Individual Retirement Account): A personal retirement account you can open independent of your employer. Two main types: Traditional (contributions may be tax-deductible, withdrawals are taxed) and Roth (contributions are after-tax, withdrawals are tax-free).

L

Lease: A contract to use an asset (often a car) for a fixed period and fee, after which it's returned. You don't own the asset but pay monthly for use. Typically requires lower upfront costs than buying.
Lump-Sum Investing: Investing a large amount of money all at once, rather than gradually over time (dollar-cost averaging). Historically, lump-sum investing has slightly higher expected returns, but comes with timing risk.

M

Marginal Tax Rate: The tax rate on your last dollar of income. If you're in the 24% bracket, your marginal rate is 24% (not your average rate across all income). Important for understanding the true cost of additional income.
Mortgage: A loan to purchase real estate, secured by the property itself. If you fail to pay, the lender can foreclose. Most mortgages are amortized over 15 or 30 years.

N

Net Worth: Your total assets (home, investments, cash) minus your total liabilities (mortgage, loans, credit card debt). A snapshot of your financial position.

P

Paycheck Deductions: Amounts withheld from your paycheck for taxes, benefits, retirement contributions, etc. Gross pay minus deductions equals net pay (take-home).
PMI (Private Mortgage Insurance): Insurance you pay if you put down less than 20% on a home purchase. It protects the lender if you default. Once your equity reaches 20%, you can request PMI removal, saving ~$100–300/month.
Principal: The original amount of money borrowed (or invested). In a loan, your monthly payment is split between principal (reducing the loan balance) and interest (the lender's fee).

R

Rebalancing: Periodically adjusting your portfolio back to your target allocation. If stocks rise and now make up 75% (instead of your target 60%), you sell stocks and buy bonds to rebalance.
Required Minimum Distribution (RMD): The minimum amount you must withdraw from certain retirement accounts (Traditional IRA, 401k) starting at age 73 (as of 2023). The IRS requires this to ensure taxes are eventually paid.
Roth 401(k): An employer-sponsored retirement account where contributions are after-tax (unlike a Traditional 401k). Growth and withdrawals in retirement are tax-free, making it powerful for high earners.
Roth IRA: A personal retirement account where contributions are after-tax. Growth and withdrawals are tax-free in retirement, and there are no required minimum distributions. Contribution limits apply ($7,000/year for most people in 2024).

S

Savings Rate: The percentage of your income that you save instead of spend. If you earn $100,000 and save $30,000, your savings rate is 30%. Higher savings rates accelerate wealth building.
S&P 500: The Standard & Poor's 500 Index: a basket of 500 large-cap U.S. companies weighted by market cap. Often used as a benchmark for the overall U.S. stock market and the basis for index funds.
Safe Withdrawal Rate: The percentage of your portfolio you can withdraw annually in retirement while minimizing the risk of running out of money. The 4% rule is the most famous example.
Sequence of Returns Risk: The risk that market returns arrive in an unfavorable order, especially early in retirement. Poor stock returns right after you retire are more harmful than poor returns later, because withdrawals amplify losses.
Social Security: A U.S. government program that pays retirees a monthly benefit based on work history and contributions. You can claim as early as 62 or delay until 70 to get higher payments.
Student Loan: A loan to pay for education, typically with lower interest rates than credit cards. Federal loans may offer income-driven repayment plans, forgiveness programs, and deferment options.

T

Tax Bracket: A range of income subject to a specific tax rate. U.S. federal tax brackets are progressive: 10%, 12%, 22%, 24%, 32%, 35%, 37%. You don't pay one rate on all income; each bracket is taxed at its own rate.
Tax-Loss Harvesting: Selling losing investments to realize capital losses that offset capital gains (or up to $3,000 of ordinary income). You can then buy a similar investment to stay invested, harvesting the tax benefit.
Term Life Insurance: Life insurance that covers you for a fixed term (e.g., 20 or 30 years) at a low, fixed premium. Pays a death benefit if you die during the term, but builds no cash value.
Traditional IRA: A personal retirement account where contributions may be tax-deductible in the year made. Growth is tax-deferred, but withdrawals in retirement are taxed as ordinary income.
True Cost of Car: The total expense of owning a car over its lifetime: purchase price, depreciation, fuel, insurance, maintenance, registration, and financing costs. Often much higher than purchase price alone.

V

Vesting Schedule: The timeline for when you gain ownership of employer contributions to your retirement plan (e.g., 401k match). A common schedule vests 25% per year over 4 years; you forfeit unvested amounts if you leave.

W

W-2: A tax form showing your annual wages and taxes withheld as a W-2 employee. You receive it from your employer by January 31 and use it to file your tax return.
