Why This Glossary Exists
Credit reports, loan disclosures, and card statements are full of terms that sound technical but aren't hard to understand once someone explains them plainly. This glossary defines the words you're most likely to encounter — alphabetically organized, jargon-free, and focused on what each term actually means for you as a borrower.
For a broader foundation, see Understanding Credit and Debt From the Ground Up, which covers how credit works, how scores are built, and how repayment strategies compare. When you're ready to apply these terms to your own file, Reading Your Credit Report for the First Time walks through every section line by line.
This article is general financial information and education, not personalized financial or legal advice. For decisions specific to your situation, consult a licensed financial professional.
APR (Annual Percentage Rate)
The yearly cost of borrowing expressed as a percentage, including interest and certain fees. It lets you compare the true cost of different loans or credit products on an apples-to-apples basis. A higher APR means you pay more to carry a balance.
Principal
The original amount borrowed, before any interest is added. When you make a loan payment, part goes toward interest and the remainder reduces the principal — the part that actually shrinks your debt.
Credit Utilization
The percentage of your available revolving credit (such as credit card limits) that you're currently using. For example, a $500 balance on a $2,000 limit is 25% utilization. It's a significant factor in most credit scoring models.
Hard Inquiry
A review of your credit report triggered when you apply for new credit — a card, loan, or mortgage. Hard inquiries typically have a small, temporary effect on your credit score and remain visible on your report for about two years.
Soft Inquiry
A credit check that does not affect your score. Examples include checking your own credit, pre-qualification checks by lenders, and background checks by employers. Only you can see soft inquiries on your own report.
Charge-Off
When a creditor declares a seriously delinquent debt (typically after 120–180 days of non-payment) as a loss on their books. A charge-off does not erase the debt — you still owe it — and it remains on your credit report for up to seven years.
Minimum Payment
The smallest amount a lender requires you to pay each billing cycle to keep the account current. Paying only the minimum on revolving debt often extends repayment for years and significantly increases the total interest paid.
Grace Period
A window of time — typically 21–25 days after a billing cycle closes — during which you can pay your statement balance in full and avoid interest charges on purchases. Not all loans have a grace period; credit cards commonly do.
Revolving Credit
A credit arrangement with a reusable limit, such as a credit card or home equity line of credit. You borrow, repay, and borrow again up to your limit. Your balance and required payments fluctuate based on usage.
Installment Loan
A loan repaid in fixed, regular payments over a set term — mortgages, auto loans, and student loans are common examples. Unlike revolving credit, the limit does not reset as you pay down the balance.
Delinquency
The status of a loan or credit account when a payment is past due. Delinquency is typically reported to credit bureaus after 30 days and can negatively affect your credit score; the impact generally increases the longer the account remains unpaid.
Debt-to-Income Ratio (DTI)
Your total monthly debt payments divided by your gross monthly income, expressed as a percentage. Lenders use DTI to assess whether you can realistically afford additional debt. A lower DTI is generally viewed more favorably.
Key Concepts Worth Expanding
APR in practice. A card's APR is divided by 365 to get a daily periodic rate, which is applied to your average daily balance each billing cycle. Even a modest balance compounds quickly — How Interest Compounds on Revolving Debt walks through exactly how that math works and why minimum payments can keep a balance alive far longer than most people expect.
Credit utilization and your score. Utilization — the share of available revolving credit you're currently using — is one of the more actively shifting inputs in most scoring models. Keeping it low is generally considered favorable, but the exact impact varies by model and individual profile. See Credit Utilisation: The Ratio That Lenders Watch Closely for a full breakdown of how it's calculated.
Secured vs. unsecured debt. Whether collateral backs a loan changes what happens when a borrower defaults. Secured vs. Unsecured Debt: What's the Real Difference? explains the practical consequences of each structure.
Credit scores as a summary. The score itself is a three-digit output of a complex model — not an identity or a moral judgment. Credit Scores Explained: What the Number Actually Means covers what the number represents and the factors that move it up or down.
