APR, charge-off, hard inquiry, debt-to-income ratio — clear definitions of the terms you'll encounter when managing credit and debt.
Why Credit and Debt Vocabulary Matters
When you apply for a loan, review a credit card agreement, or check your credit report, you're confronted with a dense set of industry terms. Misreading even one — say, confusing APR with a simple interest rate — can lead to costly misunderstandings. This reference guide defines the most common terms you'll encounter, in plain language you can act on.

Core Credit and Debt Terms Defined
Use the glossary below as a lookup reference. Terms are grouped by concept area to make related ideas easier to compare.
Annual Percentage Rate (APR)
The yearly cost of borrowing expressed as a percentage, including both interest and certain fees. APR gives you a more complete picture of borrowing costs than the interest rate alone, making it the better number to compare across loan offers.
Credit Utilization Ratio
The percentage of your available revolving credit that you are currently using. For example, a $2,000 balance on a $10,000 credit limit equals 20% utilization. Lower utilization generally supports a stronger credit score.
Hard Inquiry
A review of your credit report triggered when a lender evaluates your application for credit. Hard inquiries can temporarily lower your credit score by a few points and remain on your report for up to two years.
Soft Inquiry
A credit check that does not affect your credit score, such as when you check your own credit or when a lender pre-screens you for an offer. Soft inquiries are visible only to you, not to other lenders.
Debt-to-Income Ratio (DTI)
Your total monthly debt payments divided by your gross monthly income, expressed as a percentage. Lenders use DTI to gauge how much additional debt you can reasonably manage. A lower DTI signals stronger repayment capacity.
Charge-Off
When a creditor declares a seriously delinquent debt (typically 120–180 days past due) as a loss on its books. A charge-off does not erase what you owe — the debt may be sold to a collection agency — and it damages your credit report for up to seven years.
Revolving Credit
A type of credit with a reusable limit that you can borrow against, repay, and borrow again — such as a credit card or home equity line of credit. The balance and minimum payment fluctuate based on how much you use.
Installment Loan
A loan repaid in fixed, scheduled payments over a set term, such as a car loan, personal loan, or mortgage. Unlike revolving credit, the credit limit does not replenish as you pay it down.
Principal
The original amount of money borrowed, not including interest or fees. Interest charges accrue on the outstanding principal balance, so reducing principal faster generally reduces total interest paid.
Delinquency
A status that occurs when a payment is past its due date. Most lenders report delinquency to credit bureaus after 30 days, and the negative mark intensifies at 60-, 90-, and 120-day intervals.
Secured vs. Unsecured Debt
Secured debt is backed by collateral (an asset the lender can claim if you default), such as a mortgage or auto loan. Unsecured debt — like most credit cards and personal loans — relies solely on your promise to repay, which typically means higher interest rates.
Grace Period
A window of time after a billing cycle closes during which you can pay your credit card balance in full and avoid interest charges. Not all loan types include a grace period, so always confirm the terms with your lender.
Understanding these definitions side by side can reveal how they interact. For example, a high debt-to-income ratio often reflects a pattern of high utilization across revolving accounts — both of which affect your credit score.
If you're managing credit cards specifically, our guide on managing credit cards without accumulating debt explains how these concepts apply in everyday use. And if you're weighing whether a particular loan is worth taking on, our article on good and bad debt offers a more nuanced framework than the common shorthand suggests.

Americans with a subprime credit score (below 670)
According to FICO data, roughly one in four U.S. adults carries a credit score that lenders typically classify as subprime, limiting access to favorable loan terms.
