Plain-English glossary

Every confusing money word, explained simply. 88 terms and growing.

1099 / Independent contractor: A worker who is paid in full with no taxes withheld and reported on a 1099 form. Contractors owe both halves of FICA (15.3% self-employment tax) and pay quarterly estimated taxes themselves.
401(k) match: Free money: when your employer adds to your retirement account based on what you contribute, up to a limit. Always try to contribute enough to get the full match.
50/30/20: A simple starter budget that splits your take-home pay into 50% needs, 30% wants, and 20% saving and debt. Treat the percentages as a starting point you adjust to your real life, not a fixed rule.
Amortization: How a loan is paid off over time in equal payments. Early payments are mostly interest; later payments are mostly principal.
APR (Annual Percentage Rate): The yearly cost of borrowing money, shown as a percentage. On a credit card, your APR divided by 365 is roughly what you are charged per day on a balance.
APY (Annual Percentage Yield): The yearly amount you earn on savings, including the effect of compounding. A higher APY means your money grows faster.
Avalanche method: A debt-payoff strategy that targets your highest-interest-rate debt first while paying minimums on the rest. Because it kills the most expensive interest first, it pays the least total interest of any order.
Average daily balance: The average of what you owed each day across a billing cycle. Card interest is charged on this average, not on your starting or ending balance — which is why paying down a balance earlier in the cycle lowers the interest.
Beneficiary: The person you name to receive a policy's or account's money if you die. Naming one — and keeping it current after big life changes — is free, takes minutes, and keeps the money from getting stuck in legal limbo.
Brokerage account: An account at a company that holds your investments and executes purchases — the investing equivalent of a bank account. Look for $0 minimums, no commissions on basic trades, and index funds on the menu.
Buy Now, Pay Later (BNPL): A short installment plan that splits a purchase into four equal, interest-free payments (Klarna, Afterpay, etc.). The risk is not interest but late fees and stacking several plans until the combined payments overwhelm your budget.
Capitalization (student loans): The moment unpaid interest is added to a loan's principal, so future interest accrues on the bigger balance. It mainly happens when you exit a deferment on an unsubsidized loan or when you consolidate — one unpaid year quietly raises the cost of every year after.
Cash advance: Using your credit card to get actual cash (for example at an ATM). It gets no grace period, so interest starts immediately, usually at a higher APR, plus an upfront fee of 3–5%. One of the most expensive ways to borrow.
Compound interest: Interest calculated on your original money plus the interest already added. It is why savings snowball over time — and why debt can spiral.
Copay: A flat, fixed fee (like $20 or $30) you pay for a covered doctor visit or prescription, with the health plan covering the rest of that service's cost. Short for "copayment."
Credit: Borrowing money you promise to pay back, usually with interest. The word also means your reputation for paying it back, which lenders, landlords, and sometimes employers can check.
Credit freeze: A free, reversible lock you place on your credit file with the credit bureaus. It blocks new accounts from being opened in your name, which stops most identity theft; you lift it temporarily when you actually apply for credit.
Credit report: The detailed file the credit bureaus keep on your borrowing — accounts, balances, and payment history. Your credit score is calculated from it. Get yours free at AnnualCreditReport.com and dispute any errors.
Credit score: A number (commonly 300–850) that lenders use to judge how reliably you repay debt. Higher is better and means cheaper borrowing. Payment history and credit utilization move it the most.
Credit utilization: The share of your available credit you are using — your balance divided by your credit limit. A major factor in your credit score; keeping it well under 30% generally helps.
Daily periodic rate (DPR): Your credit card APR divided by 365 — the slice of interest charged each day on what you owe. A 24% APR is about 0.0658% per day, applied every day of the billing cycle.
Debt collections: When an unpaid debt is handed to (or sold to) a company whose job is to collect it. Federal law (the FDCPA) gives you rights: written validation of the debt, freedom from harassment, and the ability to limit contact in writing.
Debt consolidation: Combining several debts into one new loan or payment — one due date, ideally one lower rate. It only saves money if the total interest actually drops and you avoid running the old balances back up.
Deductible (insurance): The amount you pay out of your own pocket before your insurance starts sharing the cost. Choosing a higher deductible usually lowers your premium — pick one your emergency fund could cover without flinching.
Deferment: A legal pause on federal student loan payments — while in school, unemployed, or in hardship. On an unsubsidized loan, interest keeps accruing the whole time and can capitalize when the deferment ends.
Direct deposit: Having your paycheck sent electronically straight into your bank account instead of as a paper check. It is faster, free, and often the easiest way a bank will waive a monthly account fee.
Diversification: Spreading your money across many companies instead of betting on one, so a single company's collapse barely dents you. An index fund diversifies automatically — one purchase holds hundreds of companies.
Down payment: The upfront chunk of a home's price you pay in cash, with a mortgage covering the rest. Putting 20% down avoids mortgage insurance, but that's a guideline, not a law — many buyers put down less.
Emergency fund: Money set aside only for unexpected costs (a car repair, a medical bill, a lost job). A starter goal is $1,000; a fuller goal is 3–6 months of essential expenses.
Estimated taxes: Quarterly payments you send the IRS yourself when no employer is withholding for you — generally required if you'll owe $1,000 or more for the year. The pay-as-you-go system for side income and self-employment.
Expense ratio: The percentage of your money a fund skims every year to run itself. Index funds typically charge a tiny fraction (often 0.05% or less) of what stock-picking funds charge — a gap that compounds in your favor for decades.
FDIC insurance: Federal protection that guarantees the money in your bank deposit accounts (up to the legal limit) even if the bank fails. Look for "FDIC-insured" when choosing a bank — credit unions have equivalent NCUA coverage.
FICA: Payroll taxes for Social Security and Medicare, automatically taken from your paycheck (7.65% of pay for most employees).
Fixed rate: An interest rate that stays the same for the entire life of the loan or account, so your cost is predictable and never moves on its own.
Flexible spending account (FSA): An employer account that lets you pay predictable medical costs (glasses, copays, prescriptions) with pre-tax money. Use-it-or-lose-it: money unspent at the plan-year deadline is forfeited, so fund it only to what you'll actually spend.
Forbearance: A temporary pause or reduction of federal student loan payments, typically during financial difficulty. Interest always keeps accruing during a forbearance, so the balance keeps growing while payments rest.
Grace period: The window between your credit card statement date and due date. Pay the full statement balance within it and you owe zero interest. Carry a balance and you lose it.
Gross pay: Your salary before any taxes or deductions are taken out.
Hard vs. soft inquiry: A soft inquiry (like checking your own score) does not affect your credit. A hard inquiry happens when a lender checks your credit because you applied for something, and it can lower your score slightly and temporarily.
Health savings account (HSA): A medical savings account available only with a high-deductible health plan. Money goes in pre-tax, grows untaxed, and comes out tax-free for qualified medical costs — and unlike an FSA, it's yours forever and rolls over every year.
High-deductible health plan (HDHP): A health plan with lower monthly premiums and a higher deductible — the amount you pay before insurance kicks in. It's the only plan type that lets you contribute to an HSA.
High-yield savings account (HYSA): A savings account that pays meaningfully more interest than a typical big-bank savings account, usually online.
Income-driven repayment (IDR): A family of federal student loan plans that set your monthly payment from your income, recalculated each year, with the remaining balance forgiven after a long horizon. Lower payments now usually mean a longer horizon and more total interest.
Index fund: A low-cost investment that holds a little of many companies at once, tracking the whole market instead of betting on single stocks.
Installment debt: A fixed amount you borrow once and pay back in equal scheduled payments until it reaches zero — auto loans, student loans, and mortgages. Unlike revolving debt, the schedule marches it to a known payoff date.
Itemizing: Adding up specific deductions (mortgage interest, state and local taxes, donations) and subtracting that total instead of the flat standard deduction. Only worth it when your itemized total beats the standard amount — rare on a first job.
Lease: A legally binding contract between you and a landlord setting the rent, the term (usually 12 months), and the rules for living there — including what breaking it early costs. Read every line before signing; once signed, all of it is enforceable.
Liquidity: How quickly you can turn money into spendable cash without losing value or paying a penalty. Cash in a savings account is highly liquid; an emergency fund must be liquid so it is there the moment you need it.
Loan servicer: The company hired to handle a student loan's billing, payments, and paperwork on the lender's behalf. You don't choose it and it can change — but it's who you contact about repayment plans, deferment, and payoff.
Marginal vs. effective tax rate: Your marginal rate is the rate on your next dollar earned (your top bracket); your effective rate is the average across all your income, which is always lower. A raise into a higher bracket only taxes the new dollars, never your whole income.
Minimum payment: The smallest amount you can pay on a credit card to stay current. Paying only the minimum keeps you in debt for years and maximizes interest.
Net pay: Your take-home pay — what actually lands in your account after taxes and deductions.
Open enrollment: The once-a-year window when you pick or change your workplace benefits — health plan, FSA/HSA amounts, coverage. Miss it and you're locked into this year's choices unless a qualifying life event (like marriage or losing other coverage) opens a special window.
Out-of-pocket maximum: The most you can be required to pay for covered care in a plan year — once your deductible, copays, and cost-sharing reach it, the plan pays 100% of covered services. It's the cap that makes a health plan's worst case a known number.
Overdraft: Spending more than your checking balance. With overdraft "coverage" turned on, the bank lets the charge through and hits you with a flat fee (often about $35); turn it off and the card simply declines instead.
Pay yourself first: The habit of moving money into savings on payday, before you spend on anything else — like a bill owed to your future self. It beats saving "whatever is left over," which is usually nothing.
Payday loan: A small, short-term loan due in full on your next payday, with a flat fee that hides a triple-digit APR (a typical one is around 400%). It is built around rollovers, so a quick fix often becomes a months-long debt trap — try cheaper alternatives first.
Penalty APR: A much higher interest rate (often around 29.99%) a credit card can apply to your balance after a late payment. It can stay in effect for months, making the same balance far more expensive — which is why on-time payment matters.
Premium: The amount you pay, usually monthly, just to have an insurance policy — the small, known cost you trade for protection against a much bigger one. On workplace health plans it typically comes out of your paycheck pre-tax.
Principal: The original amount of money you borrowed or invested, before any interest.
PSLF (Public Service Loan Forgiveness): A federal program that forgives your remaining federal student loan balance after 120 qualifying monthly payments — ten years' worth, not necessarily consecutive — while working for a qualifying employer (government or many nonprofits). Certify your employment annually so payments are counted as you go.
Refinancing: Replacing an existing loan with a new one, usually to get a lower interest rate or change the term. Because a new loan can carry fees and a longer term, compare the total cost over the full term, not just the monthly payment.
Revolving debt: Debt with a credit limit you can borrow against, repay, and borrow against again, with no fixed payoff date — a credit card is the classic example. The balance "revolves" up and down, and nothing forces it to zero but you.
Roth account: A retirement account you fund with money you have already paid tax on, so qualified withdrawals in retirement are tax-free.
Rule of 72: A quick shortcut: divide 72 by the annual interest rate to estimate how many years it takes money to double. At 6%, that is about 12 years.
Secured credit card: A starter credit card you back with a refundable cash deposit, which becomes your credit limit. Because the deposit lowers the lender's risk, it is approvable with no credit history and reports your activity to the bureaus, helping you build credit.
Secured vs. unsecured debt: Secured debt is backed by something you own (collateral) the lender can take if you stop paying — a house for a mortgage, a car for an auto loan — so its rate is usually lower. Unsecured debt (most credit cards and personal loans) has no collateral, just your promise, so it carries a higher rate.
Security deposit: Money you give a landlord before moving in (often about one month's rent) that they hold against damage or unpaid rent, returned under your state's rules minus documented damage beyond normal wear. Photograph everything at move-in — the photos are what get it back.
Self-employment tax: The 15.3% Social Security and Medicare tax (both the employee and employer halves) owed on 92.35% of net self-employment earnings once you net $400 or more in a year. It applies on top of regular income tax.
Simple interest: Interest calculated only on the original amount, never on interest already added.
Sinking fund: Money you set aside a little each month for a known, irregular cost that you can see coming (like annual car insurance or the holidays). Dividing a big once-a-year bill by 12 turns it into a calm monthly habit instead of a budget shock.
Snowball method: A debt-payoff strategy that targets your smallest balance first, regardless of rate, then rolls that payment into the next debt. You pay a little more interest than avalanche, but you clear a whole debt fast for an early motivational win.
Social Security wage base: The annual wage ceiling above which the 6.2% Social Security tax stops applying — $184,500 in 2026. Medicare tax has no such cap.
Standard deduction: A flat amount of income the IRS lets you subtract before figuring your tax — $16,100 for a single filer in 2026. Most first-job filers take it instead of itemizing.
Statement balance: The amount you owed on a credit card at the moment the billing cycle closed — the number you are billed for. Pay this in full by the due date to owe no interest, separate from the current balance that keeps moving as you spend.
Subsidized vs. unsubsidized loans: On a subsidized federal student loan, the government pays the interest while you're in school and during deferment. On an unsubsidized loan, interest accrues from day one and all of it is yours — which is why unpaid stretches are so expensive.
Tax credit: An amount subtracted directly from your tax bill, dollar-for-dollar — a $2,500 credit saves the full $2,500. A credit always beats a same-size deduction.
Tax deduction: An amount subtracted from your taxable income before tax is figured, so it's worth your marginal rate — a $2,500 deduction in the 12% bracket saves about $300, not $2,500.
Tax refund vs. liability: Your liability is the tax you actually owe for the year; a refund is just money returned when your withholding was more than that liability. A refund is your own money back, not a bonus.
Term (of a loan): How long you have to pay a loan back, usually in months. A longer term lowers the monthly payment but adds months of interest, so it raises the total you pay; a shorter term costs more monthly but far less overall.
Term life insurance: Life insurance that covers you for a set period (often 10–30 years) and pays your beneficiary only if you die during that term. It's pure protection with no investment component, which is why it costs less than whole life for the same coverage.
Time horizon: How long until you will actually need the money you are saving. A short horizon (a few years or less) calls for safe cash savings; a long horizon (many years) is where investing fits.
Two-factor authentication (2FA): A second login step beyond your password — usually a code from an app or a tap on your phone — so a stolen password alone can't get into your account. Use an authenticator app over text-message codes where you can.
Variable rate: An interest rate tied to an outside index (like the prime rate), so it can rise or fall over time — meaning your cost can change without you doing anything. Most credit cards use one.
Vesting: The schedule by which employer retirement contributions become permanently yours. Your own contributions are always 100% yours immediately; employer match money may unlock over a few years — leave before it vests and you forfeit the unvested part.
W-2: The year-end form from your employer summarizing what you earned and what taxes were withheld. You use it to file your tax return.
W-4: The form you give your employer that tells them how much tax to withhold from each paycheck.
Withholding: The federal (and state) income tax your employer takes out of each paycheck and sends to the government on your behalf, based on your W-4.
