Deep Dive
Step-by-step breakdown
Step 1. A
The credit industry uses specialized terminology drawn from banking regulation, statistical modeling, and consumer law. Terms that appear straightforward often have precise technical definitions that differ from colloquial usage. Understanding these definitions at the institutional level -- how regulators define them, how scoring models interpret them, and how creditors apply them -- provides a foundation for navigating credit reports, disputes, and lending decisions effectively.
Many credit terms have different meanings in different contexts. 'Default' means one thing in a credit card agreement (missed minimum payment), another in a mortgage agreement (specific contractual breach conditions), and yet another in regulatory reporting (Metro 2 Account Status codes 80-97). Similarly, 'credit limit' has a standard definition for revolving accounts but a different treatment for charge cards (which report 'high balance' instead). These contextual differences affect how information appears on credit reports and how scoring models process it.
This glossary provides institutional-level definitions for credit terms as they function within the FCRA, Metro 2 reporting standard, FICO scoring framework, and major lending regulations. Where a term has different applications across these contexts, the glossary notes the distinctions.
- Adverse Action: A creditor decision to deny, revoke, or change the terms of credit. Governed by ECOA/Regulation B, which requires written notice with specific reasons within 30 days.
- Annual Percentage Rate (APR): The annualized cost of borrowing including interest and certain fees, calculated per Truth in Lending Act (TILA/Regulation Z) methodology. Includes periodic interest but excludes certain closing costs.
- Authorized User (AU): A person added to a credit account who can make purchases but is not legally liable for the balance. The account history reports to the AU's credit file under Regulation B (12 CFR 1002.7).
- Account Status Code: A Metro 2 field (positions 17-18) that reports the current condition of an account. Codes include 11 (current), 71 (30 days late), 78 (60 days), 80 (90 days), 84 (charge-off).
- Automated Consumer Dispute Verification (ACDV): The electronic form bureaus use to forward consumer disputes to data furnishers through the e-OSCAR system. Limited character fields may compress dispute details.
Step 2. APR (Annual Percentage Rate)
APR is calculated according to the methodology prescribed by the Truth in Lending Act (TILA, 15 USC 1601 et seq.) and implemented through Regulation Z (12 CFR 1026). For credit cards, APR represents the periodic interest rate multiplied by the number of periods in a year. For mortgages, APR includes both interest and certain prepaid finance charges (origination fees, mortgage insurance premiums), making it a broader cost measure than the note rate alone.
Variable APRs are typically calculated as a margin plus a benchmark index. Most credit card variable APRs use the Wall Street Journal Prime Rate as the index (currently 8.50% as of Q1 2026). When the Federal Reserve raises the federal funds rate, the Prime Rate moves correspondingly, and all variable-rate credit card APRs adjust. A card with a 'Prime + 16.49%' margin would have a current APR of 24.99%. The CARD Act of 2009 limits when issuers can increase APRs on existing balances and requires 45 days notice for rate increases.
Penalty APRs -- higher rates triggered by late payments -- are separately disclosed and can reach 29.99% or higher. Under the CARD Act, penalty APRs can only be applied to new transactions after two consecutive late payments, and the issuer must review the account every 6 months to determine if the penalty rate should be reduced. Some issuers (notably Citi and Discover) have eliminated penalty APRs entirely, while others (Capital One, Chase) maintain them but with the CARD Act review requirement.
- Balance Transfer: Moving existing debt from one credit card to another, typically at a promotional 0% APR for 12-21 months. The transfer fee (3-5% of the transferred amount) effectively creates a one-time interest charge.
- Bankruptcy: Federal court proceeding under Title 11 of the US Code. Chapter 7 (liquidation) remains on credit reports for 10 years from filing date. Chapter 13 (reorganization) remains for 7 years from filing date.
- Bureau (Credit Bureau/CRA): A Consumer Reporting Agency under FCRA Section 603(f). The three nationwide CRAs are Equifax, Experian, and TransUnion. Specialty CRAs include ChexSystems (banking), LexisNexis (insurance/tenant), and NCTUE (utilities).
- Business Days: Under FCRA, business days exclude Saturdays, Sundays, and federal holidays. The 30-day investigation window uses calendar days, but bureau response deadlines and freeze processing use business days.
- Billing Cycle: The period between credit card statement closing dates, typically 28-31 days. Utilization is measured at the statement closing date, not the payment due date.
Step 3. Authorized User
An authorized user is a person added to a credit card account by the primary cardholder. The legal framework for AU reporting rests on Regulation B (12 CFR 1002.7), which was originally designed to ensure spousal credit access under the Equal Credit Opportunity Act. When an AU is added, the full account history (open date, limit, balance, payment record) reports to the AU's credit file at the next statement cycle.
The AU mechanism is exploited in credit building because FICO Score 8 and earlier versions treat AU tradelines similarly to primary account tradelines for scoring purposes. The entire account history -- including years of payment data from before the AU was added -- appears on the AU's report and factors into their score. FICO Score 10 and 10T include algorithms designed to detect and potentially discount AU tradelines that appear inconsistent with the consumer's overall profile.
The 'tradeline renting' industry sells AU access on strangers' accounts for $200-$1,000+ per tradeline. While not explicitly illegal under federal law, FICO has stated its models are designed to detect piggybacking. Several tradeline companies have faced FTC scrutiny. The Fannie Mae Selling Guide (B3-5.3-08) specifically addresses how mortgage underwriters should evaluate AU accounts during underwriting.
- Charge-Off: An accounting designation where the creditor writes off the balance as a loss, typically after 180 days of non-payment. The debt is not forgiven -- it may be sold to a collector or pursued through litigation. Reports with Metro 2 Status Code 97.
- Collection Account: A tradeline opened when a debt collector reports a purchased or assigned debt to credit bureaus. Must include the original creditor's name per Metro 2 standards. 7-year reporting clock runs from the original account's DOFD.
- Consumer Reporting Agency (CRA): FCRA term for credit bureaus and tenant screening companies. Any entity that assembles consumer data for third-party use under FCRA Section 603(f).
- Credit Utilization: Balance divided by credit limit on revolving accounts, expressed as a percentage. FICO measures both per-card utilization and aggregate utilization across all revolving accounts.
Step 4. B
The B section of the credit glossary covers several foundational concepts including balance transfers, bankruptcy, and bureau operations. Balance transfers represent one of the most commonly used credit management tools, allowing consumers to consolidate high-interest revolving debt onto a card with a promotional 0% APR period. The economics of balance transfers depend on comparing the transfer fee (3-5% of the amount transferred) against the interest saved during the promotional period.
Bankruptcy law intersects with credit reporting through specific FCRA provisions. Chapter 7 bankruptcy (liquidation) discharges most unsecured debts but remains on credit reports for 10 years from the filing date. Chapter 13 bankruptcy (reorganization with a repayment plan) remains for 7 years from the filing date. Individual debts included in a bankruptcy should be updated to show 'included in bankruptcy' or 'discharged in bankruptcy' status and cannot be reported as delinquent after the discharge date.
The bureau operations framework is governed by the FCRA and overseen by the Consumer Financial Protection Bureau. Each bureau maintains its own independent database and uses its own matching algorithms to associate incoming data with consumer files. The bureaus compete for data furnisher relationships and lender customers, which creates both redundancy (most major furnishers report to all three) and gaps (smaller furnishers may report to only one or two).
- Date of First Delinquency (DOFD): The date a consumer first became 30+ days past due on the account that led to the current negative status. Controls the 7-year FCRA reporting window under Section 605(a). Cannot be reset by selling the debt to a collector.
- Data Furnisher: Any entity that reports consumer credit data to a CRA. Includes creditors, lenders, collection agencies, and public records sources. Subject to accuracy requirements under FCRA Section 623.
- Debt-to-Income Ratio (DTI): Total monthly debt payments divided by gross monthly income. Not a component of credit scores but independently evaluated by mortgage and loan underwriters. Fannie Mae maximum: 50% with compensating factors.
- Dispute: A consumer challenge to the accuracy of information on a credit report. Filed under FCRA Section 611 (to bureaus) or Section 623 (directly to data furnishers). Bureau must investigate within 30 days.
- Derogatory: Any negative credit entry including late payments, collections, charge-offs, bankruptcies, and repossessions. Impact decreases with age but remains on reports for 7-10 years depending on type.
Step 5. Balance Transfer
A balance transfer moves existing credit card debt from one issuer to another, typically to take advantage of a promotional 0% APR period lasting 12-21 months. The transfer fee is typically 3-5% of the transferred amount ($150-$250 per $5,000 transferred). The economic break-even occurs when the interest saved during the promotional period exceeds the transfer fee. At a current average credit card APR of 24.99%, transferring $5,000 at a 3% fee ($150) saves approximately $1,250 in interest over 12 months -- a clear net benefit.
Balance transfer cards have specific underwriting requirements that affect credit reports. Opening a new card generates a hard inquiry and creates a new account that lowers average account age. The new card's credit limit increases total available credit, potentially improving aggregate utilization. However, if the original card is closed after the transfer, total available credit decreases and utilization may worsen. The optimal strategy is to transfer the balance, keep the original card open at $0 balance, and pay off the transfer before the promotional period expires.
FICO scoring treats balance transfer cards the same as any other revolving account. The transferred balance appears as utilization on the new card, so a $5,000 transfer to a card with a $6,000 limit produces 83% utilization on that card -- enough to significantly impact the per-card utilization component of the score. Some consumers spread transfers across multiple cards to keep per-card utilization lower, but this creates multiple inquiries and new accounts.
- e-OSCAR: Electronic platform (Online Solution for Complete and Accurate Reporting) used by bureaus to forward disputes to data furnishers. Compresses disputes into Automated Consumer Dispute Verification (ACDV) forms with standardized codes.
- Equifax: One of three nationwide CRAs, headquartered in Atlanta, GA. Suffered a 2017 data breach affecting 147 million consumers. Uses FICO Score 5 for mortgage-specific scoring.
- ECOA (Equal Credit Opportunity Act): Federal law (15 USC 1691) prohibiting credit discrimination based on race, color, religion, national origin, sex, marital status, age, or receipt of public assistance. Implemented through Regulation B (12 CFR 1002).
- Experian: One of three nationwide CRAs, headquartered in Dublin, Ireland (US operations in Costa Mesa, CA). Uses FICO Score 2 for mortgage-specific scoring. Only major bureau without a free standalone credit lock product.
- Extended Fraud Alert: A 7-year fraud alert available to identity theft victims who have filed an Identity Theft Report. Requires creditors to take reasonable steps to verify the consumer's identity before extending credit.
Step 6. Bankruptcy
Bankruptcy is a federal court proceeding governed by Title 11 of the United States Code. The two types most relevant to consumer credit are Chapter 7 (liquidation of non-exempt assets to discharge debts) and Chapter 13 (reorganization through a 3-5 year repayment plan). Both types create a public record that appears on credit reports: Chapter 7 for 10 years from the filing date, Chapter 13 for 7 years from the filing date.
The credit impact of bankruptcy extends beyond the public record notation. All accounts included in the bankruptcy should be updated by data furnishers to show 'included in bankruptcy' or 'discharged' status with a $0 balance. If these accounts continue to report delinquent payment status or outstanding balances after the discharge date, this is a disputable error under the FCRA. Post-discharge reporting errors are among the most common credit report inaccuracies and produce significant score damage because the consumer appears to have both a bankruptcy and ongoing delinquent accounts.
Waiting periods after bankruptcy vary by loan product. Conventional mortgages (Fannie Mae/Freddie Mac) require 4 years from Chapter 7 discharge and 2 years from Chapter 13 discharge. FHA requires 2 years from Chapter 7 discharge and 1 year of satisfactory Chapter 13 payments. VA requires 2 years from Chapter 7 discharge. Auto loans from subprime lenders may be available within months of discharge. Credit cards (particularly secured cards) may be available immediately after discharge.
- FCRA (Fair Credit Reporting Act): Federal law (15 USC 1681 et seq.) governing credit reporting, consumer disputes, and data furnisher obligations. Key sections: 611 (disputes), 623 (furnisher duties), 605 (reporting periods), 612 (free reports).
- FDCPA (Fair Debt Collection Practices Act): Federal law (15 USC 1692 et seq.) regulating third-party debt collector behavior. Prohibits harassment, false statements, and unfair practices. Does not apply to original creditors collecting their own debts.
- FICO Score: Credit scoring model created by Fair Isaac Corporation, used in 90%+ of US lending decisions. Multiple versions exist simultaneously: FICO 8 (general), FICO 2/4/5 (mortgage), FICO 9 (ignores paid collections), FICO 10T (trended data).
- Forbearance: A temporary agreement to reduce or suspend payments, typically during financial hardship. Does not forgive debt. May be reported as current or delinquent depending on the agreement terms and furnisher practices.
- Frivolous Dispute: Under FCRA 611(a)(3), a bureau may dismiss a dispute that does not include sufficient information to investigate or that is substantially similar to a previously submitted dispute with no new information.
