Financial Terms.

Clear definitions for the vocabulary behind money, debt, credit, and planning.

APR · Annual Percentage Rate
The yearly cost of borrowing money, expressed as a percentage. Includes interest plus most lender fees. Higher APR = more expensive.
APY · Annual Percentage Yield
The yearly return you earn on savings, accounting for compounding. The savings counterpart to APR.
Amortization
A schedule that breaks each loan payment into interest and principal. Early payments are mostly interest; later ones are mostly principal.
Asset
Anything you own that has monetary value: cash, investments, property, vehicles.
Bear market
A sustained drop in market prices, typically 20% or more from a recent peak. Opposite of a bull market.
Bond
A loan you make to a government or company. They pay you interest and return the principal at maturity.
Budget
A plan for your money over a period of time. Permission to spend, not a punishment.
Bull market
A sustained rise in market prices. Opposite of a bear market.
Capital gains
The profit when you sell an investment for more than you paid. Often taxed at a different rate than ordinary income.
Compound interest
Interest earned on interest. Each period, the new balance grows on top of the previous balance, accelerating over time.
Credit score
A number lenders use to estimate how likely you are to repay debt. Built mostly from payment history, amounts owed, and account age.
Credit utilization
The ratio of your current credit-card balance to your credit limit. Lower is better for your credit score; under 30% is a common target.
Diversification
Owning many different investments so that one bad outcome does not sink the whole portfolio.
Dividend
A cash payment a company sends to shareholders out of profits, usually quarterly.
Emergency fund
Cash set aside in an accessible account for unexpected costs. Three to six months of essential expenses is a common target.
ETF · Exchange Traded Fund
A basket of investments that trades on an exchange like a stock. Index ETFs are a low-fee way to own a slice of a whole market.
Index fund
A fund that tries to match the performance of a market index rather than beat it. Low fees, broad ownership.
Inflation
The rate at which prices generally rise. If inflation is 3% and your savings earn 1%, you are losing purchasing power.
Interest
The price of borrowing money, or the reward for saving it. Expressed as a percentage rate.
Liability
Anything you owe: loans, credit-card balances, unpaid bills. Subtract liabilities from assets to get net worth.
Liquidity
How quickly an asset can be turned into cash without losing value. Cash is most liquid; a house is not.
Mortgage
A loan used to buy property, secured by the property itself. If you stop paying, the lender can take the property.
Mutual fund
A pooled investment fund. Bought and sold once per day at the closing price. Often more expensive than an ETF.
Net worth
Assets minus liabilities. A single number that captures your financial picture. Track the trend, not the number.
Principal
The original amount of money you borrowed or invested, before interest.
Recession
A meaningful, sustained decline in economic activity. Often defined as two consecutive quarters of negative GDP growth.
Refinancing
Replacing an existing loan with a new one, usually to lower the interest rate or change the term.
Stock
A share of ownership in a company. Stocks rise and fall with the company's fortunes and the broader market.
Tax bracket
An income range taxed at a specific rate. Only the income inside the bracket is taxed at that rate, not all of your income.
Withholding
Money your employer or bank deducts and sends to the tax authority on your behalf. Common for income and investment earnings.
