401(k)
retirementA tax-advantaged employer-sponsored retirement savings plan in the US where contributions are made pre-tax (traditional) or after-tax (Roth). Many employers match a portion of employee contributions.
Amortization
debtThe process of paying off a debt over time through regular scheduled payments. Each payment covers both interest and a portion of the principal balance.
Annual Percentage Rate (APR)
creditThe yearly cost of borrowing money, expressed as a percentage. Unlike a simple interest rate, APR includes fees and additional costs, making it a more complete measure of loan cost.
Asset
generalAnything of value you own that can be converted to cash — including savings accounts, investments, real estate, vehicles, and retirement accounts.
Asset Allocation
investingThe strategy of dividing a portfolio among different asset classes — stocks, bonds, cash, and real assets — to balance risk and return based on your goals and time horizon.
Avalanche Method
debtA debt payoff strategy where you pay minimums on all debts but direct every extra dollar to the highest-interest debt first. Minimizes total interest paid.
Balance Transfer
creditMoving an existing credit card balance to a new card, typically one offering a 0% introductory APR. Used to pause interest and pay down debt faster during the promotional window.
Bear Market
investingA period when stock prices fall 20% or more from recent highs, typically over at least two months. Often associated with economic slowdowns or recessions.
Bonds
investingDebt instruments where you lend money to a government or corporation in exchange for regular interest payments and return of principal at maturity. Generally lower risk than stocks.
Budget
budgetingA plan that allocates your income across spending categories, savings, and debt payments. A budget helps ensure you spend intentionally and live within your means.
Bull Market
investingA period of rising stock prices — typically defined as a 20% or greater increase from a recent low — often associated with economic expansion and investor optimism.
Capital Gains
investingProfit earned from selling an investment (stock, real estate, fund) for more than you paid for it. Short-term gains (held under 1 year) are taxed at ordinary income rates; long-term gains at lower rates.
Compound Interest
investingInterest calculated on both the principal and the accumulated interest from previous periods. Often called the 'eighth wonder of the world' because it allows wealth to grow exponentially over time.
Credit Score
creditA numerical rating (300–850 in the US) that represents your creditworthiness based on payment history, utilization, credit age, credit mix, and recent inquiries. Higher is better.
Credit Utilization
creditThe percentage of your available revolving credit currently in use. Calculated as current balance divided by credit limit. Keeping this below 30% (ideally under 10%) helps maximize your credit score.
Debt Consolidation
debtCombining multiple debts into a single loan, ideally at a lower interest rate and/or with a simpler single monthly payment. Can simplify repayment but doesn't reduce the total amount owed.
Debt-to-Income Ratio (DTI)
debtThe percentage of your gross monthly income that goes toward debt payments. Lenders use DTI to evaluate loan applications — most prefer a DTI below 36-43%.
Diversification
investingSpreading investments across different asset classes, sectors, and geographies to reduce risk. The idea: if one investment falls, others may hold steady or rise, smoothing out overall portfolio volatility.
Dividend
investingA portion of a company's earnings paid to shareholders, typically quarterly. Dividend-paying stocks provide income in addition to any capital appreciation.
Dollar-Cost Averaging (DCA)
investingInvesting a fixed dollar amount at regular intervals regardless of price. This strategy automatically buys more shares when prices are low and fewer when prices are high, reducing average cost over time.
Emergency Fund
budgetingA dedicated savings reserve of 3-6 months of essential living expenses, kept in a liquid account. Protects against unexpected financial setbacks without resorting to debt.
Equity

ETF (Exchange-Traded Fund)
investingA basket of securities that trades on a stock exchange like a single stock. ETFs offer instant diversification, low costs, and tax efficiency. Index ETFs track market benchmarks like the S&P 500.
Expense Ratio
investingThe annual fee charged by a mutual fund or ETF to cover operating costs, expressed as a percentage of assets. Lower is better — index funds often charge 0.03–0.20%, while active funds may charge 0.5–1.5%+.
FICO Score
creditThe most widely used credit scoring model, created by the Fair Isaac Corporation. Scores range from 300-850. About 90% of top US lenders use FICO scores in lending decisions.
Financial Independence (FI)
retirementThe point at which your investment portfolio generates enough passive income to cover all your living expenses indefinitely — making paid work optional.
Fixed Expenses
budgetingRecurring costs that remain the same each month, such as rent, mortgage payments, car loans, and insurance premiums. These are the most predictable part of a budget.
Gross Income
generalTotal income before taxes and deductions are removed. Distinct from net (take-home) income, which is what you actually receive in your paycheck.
Hard Inquiry
creditA credit check initiated when you apply for credit (a loan, mortgage, or credit card). Hard inquiries remain on your credit report for 2 years and may temporarily lower your score by a few points.
High-Yield Savings Account (HYSA)

Index Fund
investingA mutual fund or ETF that tracks a market index (like the S&P 500) by holding the same securities in the same proportions. Offers broad market exposure with minimal costs.

Net Income
generalIncome after all taxes and deductions have been removed — your actual take-home pay. Also called 'take-home pay'. Used as the basis for most personal budgets.

Portfolio
investingThe collection of all your financial investments — stocks, bonds, ETFs, real estate, cash, and other assets. A well-diversified portfolio spreads risk across multiple asset types.

Rebalancing
investingThe process of realigning a portfolio back to its target asset allocation after market movements have shifted the actual percentages. Typically done annually or when allocations drift significantly.
Roth IRA
retirementAn individual US retirement account funded with after-tax dollars. Qualified withdrawals in retirement are completely tax-free, including all investment gains.
RRSP

Snowball Method
debtA debt payoff strategy where you pay minimums on all debts but direct extra payments to the smallest balance first, regardless of interest rate. Creates psychological momentum through quick wins.

TFSA
retirementTax-Free Savings Account — a Canadian account where contributions are made with after-tax dollars but all growth and withdrawals are completely tax-free.
Traditional IRA
retirementAn individual US retirement account where contributions may be tax-deductible. Taxes are owed on withdrawals in retirement. Required minimum distributions (RMDs) start at age 73.
Variable Expenses
budgetingSpending that changes from month to month, such as groceries, dining out, entertainment, and clothing. The most flexible part of a budget and the easiest to reduce when cutting costs.
Yield
investingThe income earned on an investment, expressed as a percentage of the investment's cost or current market value. A bond with a $1,000 face value paying $50/year has a 5% yield.
Zero-Based Budgeting
budgetingA budgeting method where every dollar of income is assigned a specific purpose (spending, saving, or debt payoff) so that income minus all allocations equals zero at the end of planning.
