Quick answer

Credit has its own vocabulary, and most of it was written by lenders, for lenders, which is why so many terms sound like accusations. This glossary translates them into plain English. One rule holds throughout: these words describe account statuses and system mechanics, not your character. A "delinquency" is a date math outcome; a "derogatory mark" is an entry on a file. Knowing the words is half of feeling less pushed around by them.

The absolute basics

  • Debt: money owed. Nothing more loaded than that: a mortgage, a student loan, and a credit card balance are all debt.
  • Credit: the arrangement of borrowing now and paying later. Using credit isn't a failure to afford things; it's how most people buy homes, cars, and education.
  • Loan: borrowed money repaid over time, usually with interest added.
  • Principal: the original amount borrowed, before any interest.
  • Interest: the cost of borrowing, charged by the lender.
  • Interest rate: that cost as a percentage, so loans can be compared.
  • APR (annual percentage rate): borrowing cost expressed as a yearly rate. What it includes varies by product (a credit card's APR, for example, generally doesn't fold in most fees), so compare the APR along with the fees and terms, not the APR by itself.
  • Balance: what you currently owe on an account right now. It moves as you spend and pay, but the figure that matters for your credit is the one reported to the bureaus, usually your balance on the statement closing date, not your live day-to-day balance.
  • Minimum payment: the smallest amount that keeps an account in good standing for the month. Paying the minimum on time protects your payment history; it's a legitimate move in a tight month, not a failure.
  • Due date: when a payment must arrive. (A payment a few days past it usually means a late fee, not a credit report entry; see delinquency.)
  • Statement: the monthly summary of what was charged, paid, and owed, generated on your statement closing date. The balance on that closing date is usually what gets reported to the bureaus, a quirk that matters for utilization.
  • Grace period: on a credit card, the stretch between the end of a billing cycle and the payment due date during which you can avoid interest by paying your statement balance in full. That's separate from any lender-specific late-fee or cure period after the due date. Terms vary; it's in the fine print.
  • Autopay: payments that happen automatically. The most reliable protection for payment history, and worth checking periodically, because autopay can silently break (expired card, changed account) through no action of yours.
  • Overdraft: when a payment processes for more than the account holds at that moment. Usually a timing mismatch (a deposit clearing a day late, two bills landing the same morning), not a math failure.
  • NSF (non-sufficient funds): a payment that bounced because the account didn't cover it right then. Between you, your bank, and the biller; it does not appear on your credit report by itself.
  • Creditor / lender: who the money is owed to / who extends the credit.
  • Borrower: the person on the other side of the loan. That's it. The word carries no judgment, and neither should the role.

Credit reports and scores

  • Credit report: the file of your reported account history, meaning accounts, balances, payments, and applications. You have (at least) three, one per bureau, and they don't always match, which is one reason errors are common and worth checking for.
  • Credit bureau: one of three companies (Equifax, Experian, and TransUnion) that compile credit reports. They record what lenders send them; lenders sometimes send mistakes, which is why you have a legal right to dispute.
  • Credit score: a three-digit number (300–850) summarizing the payment history in your reports. It measures reported account behavior, not income, savings, employment, or worth as a person. A score can be low because of a thin file, old events, high balances, or plain errors; the number doesn't say which, which is why the report underneath matters more than the score on top.
  • Credit history: how long accounts have existed and how they've been handled. Its length is a scoring factor, which is why younger people score lower on average, by design, not by fault.
  • "Good" / "bad" credit: informal shorthand for score ranges lenders price against. Useful shorthand, terrible adjectives: a score describes a file, not a person, and files change.
  • Credit utilization: the share of available revolving credit currently in use. One of the biggest score factors and the most fixable one: most widely used scores respond primarily to your currently reported balance, so paying balances down tends to show up fast (though some newer models also weigh balance trends over time).
  • Credit limit: the most a lender lets you borrow on a revolving account, like a credit card. It's the denominator in your utilization, so the same balance against a higher limit means lower utilization, and closing a card removes its limit from your total available credit.
  • Hard inquiry / soft inquiry: a hard inquiry usually arises from an application or transaction you initiated (small, temporary score effect), and an inquiry made without a permissible purpose may be disputable; a soft inquiry is any other check, including you checking your own credit, which never affects your score, no matter how often.
  • Revolving credit: borrow, repay, borrow again (credit cards).
  • Installment credit: a fixed loan repaid on schedule (auto, student, personal loans). Installment balances don't count toward utilization, the mechanical reason consolidating card debt into a loan can raise a score.
  • Credit mix: having both revolving and installment accounts. A minor factor; never worth borrowing money you don't need.
  • Tradeline: industry word for a single account entry on a report.
  • Authorized user: someone added to another person's card account. When the issuer reports it (many do, some don't, and practices vary by issuer and scoring model), that account's history can show up on the authorized user's file, so a well-managed account may help while a high-balance or late-paying one may hurt. An authorized user generally isn't responsible for repaying the debt unless they're also a joint holder or otherwise liable. It can be a low-cost way to strengthen a file, but it isn't a guaranteed one.
  • Scoring model / FICO / VantageScore: the formulas that turn a report into a score. Different models and versions produce different numbers from the same file, which is why two apps show two scores. Neither is "wrong"; they're different rulers.
  • Rapid rescore: a lender-initiated paid service that updates report data faster than the normal cycle, typically during a mortgage application.

When payments go wrong (the de-shamed section)

  • Delinquency: the status an account enters when a payment is past due. Lenders generally report it to the bureaus only at 30+ days past due; a few days late means a fee, not a report entry. The word sounds criminal; it's date arithmetic.
  • Derogatory mark: industry umbrella term for any negative report entry (late payment, collection, charge-off). Worth knowing mostly because it sounds worse than what it names.
  • Charge-off: an accounting status, meaning the lender has written the debt off as a loss for their books. It does not mean the debt is forgiven or uncollectible; it means the lender's accountants moved a number. The debt can still be collected or sold.
  • Collections: an unpaid debt handed to or sold to a collection agency. Collections can appear on reports; under the nationwide bureaus' current voluntary policy, paid medical collections and unpaid medical collections with an initial reported balance under $500 generally shouldn't appear, and newer scoring models count paid collections of any kind less or not at all.
  • Dispute: the formal, free-by-law process of challenging a report entry you believe is wrong. The bureau generally has 30 days (sometimes 45) to investigate. Errors are common; disputing one isn't gaming the system, it's the system working as designed.
  • Secured credit card: a card backed by a refundable cash deposit, making approval easy without history. The standard starter and rebuilder tool.
  • Credit-builder loan: a small loan built to generate payment history; the money is typically held until the payments finish. It works, and it costs interest and fees; compare against a secured card before paying for one.
  • Debt-to-income ratio (DTI): monthly debt payments as a share of monthly income. Lenders use it alongside your score, especially for mortgages. Not part of your credit score itself.
  • Secured / unsecured debt: backed by collateral (house, car) vs. not (most cards). Matters most in hardship: secured debt can take the collateral.
  • Debt consolidation: replacing several debts with one, usually at a better rate. You still owe everything; it's reorganization, and done right it can help a score (see utilization).
  • Debt settlement: negotiating to pay less than owed, usually after payments stop. Not the same as consolidation, despite ads that blur them; settlement typically does serious credit damage along the way. The distinction protects people; that's why it's in a glossary.
  • Statute of limitations (on debt): the time limit (varies by state) for a creditor to sue over a debt. Old debt may be past it; a payment or written acknowledgment can restart the clock in some states, worth knowing before engaging with very old collections.
  • Judgment: a court ruling that a debt is owed, which can enable garnishment.
  • Garnishment: court-ordered repayment taken from wages. Requires legal process; it doesn't happen by surprise from a missed card payment.
  • Bankruptcy (Chapter 7 / Chapter 13): the legal processes for discharging (7) or restructuring (13) debt that can't be paid. Bankruptcy is a tool the law provides, not a moral verdict; it exists because sometimes the honest answer is that the math will never work, and the system offers a reset. It stays on reports for up to 10 years (Ch. 7) or 7 (Ch. 13), and people rebuild from it all the time.
  • CROA: the federal consumer-protection law governing companies that sell dispute help: no charging before services are performed, no promising to remove accurate information. If a company violates either, that's the red flag.
  • Credit freeze / lock: restricting access to your report, which makes it much harder for someone to open most new credit accounts in your name (you may need to lift it to apply for credit yourself). Free, reversible, and one of the strongest fraud protections available.
  • Public record: court-sourced items (like bankruptcies) that appear on reports outside normal account history.

Where Solid Credit fits

Most of the intimidation in credit is vocabulary: statuses that sound like verdicts. Solid's free tools do the translation on your actual file: they read your reports and tell you in plain language what each entry is, whether it looks accurate, and what (if anything) to do about it. The glossary is the general map; your reports are the territory.

This glossary is for general information, not financial or legal advice.

Common questions

There's a term on my report that isn't in this list. What do I do?

Don't assume the worst. Every entry on your report has to be accurate no matter what it's called, so if a term is unfamiliar or the details next to it don't match your records, that's a reason to look closer, not to panic. Reading the report section it sits in usually tells you what it is; our guide on how to read your credit report walks through it.

Now that I know the words, where should I actually start?

With your own reports. The vocabulary only matters once you apply it to your file, so pull all three reports and read them section by section. That's the step that turns definitions into a plan you can act on.

Which of these terms should I actually worry about?

It depends on what's on your report. The status dragging one person's score down is often irrelevant to another's, so there's no universal list to fear. Our piece on why credit advice isn't one-size-fits-all explains how to find the one or two things that actually apply to you.

Do the negative statuses, like a charge-off or a collection, stay on my report forever?

No. Most negative items age off after about seven years (a Chapter 7 bankruptcy can stay up to ten), and some come off sooner, especially paid medical collections. How long the whole picture takes to improve is its own question; we cover it in how long it takes to fix your credit.
