Familiar terms you should know

Budget

A plan for how you’ll spend and save your money. Think of it as a grocery list for your dollars—you decide what to buy now and what to save for later.

Savings

Money you tuck away today so you can use it later. It’s like seeds you plant for a bigger harvest.

Interest

The small amount a lender pays you (or you pay a lender) for borrowing or using money. It’s the “thank you” for letting someone else hold your cash.

Debt

Money you owe to someone else. Like when you borrow a toy and promise to return it plus a thank-you note.

Credit score

A number that tells lenders how risky it is to lend you money. Higher is better, like getting a gold star for paying on time.

Loan

Money you borrow that you promise to pay back, usually with interest. It’s a temporary cash boost for bigger purchases or needs.

Mortgage

A loan specifically for buying a home. You pay back a little each month, and the house is the collateral if you don’t pay.

Inflation

The general rise in prices over time. It’s why your dollar might buy less next year than today.

Emergency fund

Extra money set aside just in case something unexpected happens, like a car repair or a broken appliance. It’s your financial safety net.

Diversification

Don’t put all your eggs in one basket. Spread money across different types of investments so one poor choice doesn’t ruin everything.

Risk

The chance that you might lose some or all of your money. Higher potential reward usually means higher risk.

Return

The money you earn from an investment, including gains and income like interest or dividends.

A charge for handling money, buying something, or managing an investment. Sometimes small, sometimes sneaky—watch for them.

Commission

A fee paid to a person (like a broker) for helping you buy or sell something, often a percentage of the deal.

Index

A measurement that shows how a group of investments is doing. It’s like a report card for the market.

Mutual fund

A pool of many people’s money invested together in lots of stocks and/or bonds. A manager helps choose what to buy.

Exchange-traded fund (ETF)

A fund like a mutual fund, but it trades on an exchange like a stock. It can be bought and sold throughout the day.

Stock

Owning a piece of a company. If the company does well, your stock can rise in value and pay dividends.

Bond

A loan you give to a company or government. You get regular interest payments and your original money back at the end.

Dividend

A small share of a company’s profits paid to shareholders. It’s like a “thank you” gift for owning the stock.

Asset

Anything valuable you own (cash, stocks, a house, a car). If it can be sold for money, it’s an asset.

Liability

Something you owe money on, like a loan or credit card balance. It’s money you’re responsible for paying.

Net worth

The total value of your assets minus your liabilities. It’s your financial scoreboard.

Principal

The original amount of money you borrow or invest, before interest or growth.

APR

Annual Percentage Rate—the yearly cost of borrowing, including interest and some fees. It helps you compare loans.

Interest rate

The percentage charged or earned on money borrowed or saved. It’s the rate that makes money grow or shrink.

Debit card

A card that spends money directly from your bank account. It’s like using cash, but fast and digital.

Credit card

A card that lets you borrow money to spend now and pay later. It can build your credit if you pay on time, but watch the interest.

Already covered above, but worth noting again: a loan to buy a home with the house as collateral.

Refinance

Replacing an old loan with a new one—usually to get a lower rate or lower monthly payments.

Amortization

How a loan is paid off over time. Early payments often cover more interest; later payments cover more principal.

Budget variance

Inflation rate

The speed at which prices are rising in general. A higher rate means prices go up faster.

Recession

A period when the economy shrinks, people may lose jobs, and spending slows down. Not fun, but common in cycles.

Liquidity

Dollar-cost averaging
