How to Use This Glossary
Credit reports are dense documents filled with industry language that most people were never taught. If you've ever opened yours and felt lost, you're not alone. This reference is designed to give you plain-English definitions for the terms you're most likely to encounter — no financial background required.
If you're newer to these concepts, the plain-language starting point for credit and debt is a good place to begin before diving into individual terms. If you want a walkthrough of how a credit report is actually structured, see Reading Your Credit Report Without Getting Lost.

Why These Terms Matter for Your Score
Knowing the vocabulary is only half the picture. Understanding how these items connect to your actual credit score helps you make sense of why a score moves up or down.
Payment history and credit utilization together account for roughly 65% of a standard FICO score. That means on-time payments and keeping balances reasonable relative to your limits are the two levers with the most impact. Derogatory marks like charge-offs and collection accounts sit in the payment history category and can drag a score down significantly — though their impact typically fades over time.
