Análisis profundo
The belief that credit scores begin at age 25 likely stems from confusion between the minimum age to independently open a credit account (18 under the CARD Act of 2009, or 21 without a cosigner or proof of income) and when a score is first generated. FICO and VantageScore do not reference a consumer's date of birth anywhere in their scoring algorithms.
A credit score is generated once a consumer has at least one account reported to a credit bureau that meets minimum scoring criteria. For FICO, this requires at least one account that has been open for six months and at least one account reported to the bureau within the past six months. VantageScore 3.0 and 4.0 can generate a score with as little as one month of history on a single account.
According to Experian data from 2023, approximately 67 million Americans have thin credit files or no credit file at all. Many of these consumers are under 25, but the barrier is lack of reported accounts rather than age.
A credit score is generated when a consumer meets the minimum scoring criteria of a particular model. When a person is added as an authorized user on a parent's credit card at age 16, that account's full history may appear on the minor's credit report. If the account meets FICO's six-month threshold, a score will be generated regardless of the user's age.
The initial score a consumer receives depends entirely on the characteristics of their first reported accounts. A consumer whose first account is a secured credit card with a $500 limit and on-time payments for six months will typically see an initial FICO score between 630 and 670. A consumer whose first reported item is a collections account will see an initial score well below 600.
VantageScore's ability to score thinner files means that more young consumers can receive a score earlier than under FICO alone. As of 2024, VantageScore claims it can score approximately 37 million more consumers than conventional models, many of whom are in the 18-24 age range.
FICO Score 8, the most widely used model, weights five categories: payment history (35%), amounts owed (30%), length of credit history (15%), new credit (10%), and credit mix (10%). None of these categories involve the consumer's chronological age. The 'length of credit history' category measures the age of accounts on the credit report, not the age of the person.
VantageScore 4.0 uses six categories with different weightings: payment history (41%), depth of credit (20%), utilization (20%), balances (6%), recent credit (5%), and available credit (3%). Trended data, which tracks whether balances are increasing or decreasing over time, plays a larger role in VantageScore 4.0 than in FICO 8.
A 22-year-old who was added as an authorized user on a parent's credit card at age 15 can have a longer credit history (7 years) than a 30-year-old who opened their first account at age 28 (2 years). The 22-year-old would score higher on the length-of-history component despite being younger.
Experian's 2023 State of Credit report shows average FICO scores by generation: Gen Z (18-26) averaged 680, Millennials (27-42) averaged 690, Gen X (43-58) averaged 709, Baby Boomers (59-77) averaged 745, and the Silent Generation (78+) averaged 761. These differences correlate with length of credit history and financial behavior patterns, not with any age-based scoring mechanism.
Younger consumers tend to have shorter credit histories, fewer accounts, and higher utilization ratios. The average Gen Z consumer has 2.1 open accounts compared to 5.8 for Baby Boomers. Higher utilization among younger consumers (30% average for Gen Z versus 15% for Boomers) accounts for a significant portion of the score gap.
The Federal Reserve Bank of New York's 2023 Household Debt and Credit Report found that consumers aged 18-29 had an average of $6,004 in credit card debt with lower credit limits, producing higher utilization. Consumers aged 60-69 averaged $6,650 in credit card debt but with significantly higher credit limits, producing lower utilization ratios.
Consumers under 18 can begin building credit through authorized user status. A 2022 study by the Consumer Financial Protection Bureau found that authorized users gained an average of 30-35 points on their FICO score compared to peers with equivalent standalone accounts. The key factor is that the primary cardholder's payment history and account age transfer to the authorized user's report.
Secured credit cards remain the most accessible entry point for consumers with no credit history at any age. These cards require a refundable deposit (typically $200-$500) that serves as the credit limit. Major issuers including Discover, Capital One, and Bank of America report secured card activity to all three bureaus. After 6-12 months of on-time payments, most issuers will upgrade the account to an unsecured card and return the deposit.
Credit-builder loans, offered by institutions like Self Financial and many credit unions, work by holding the loan proceeds in a savings account while the borrower makes monthly payments. These payments are reported to the bureaus. A 2020 CFPB study found that credit-builder loans increased scores by an average of 60 points for consumers who had no existing debt, but had minimal effect for consumers who already carried other debt obligations.
The time from account opening to first FICO score generation varies by account type. Credit cards and retail cards typically appear on bureau reports within 30-60 days of the first statement closing. Since FICO requires six months of history, a consumer opening their first credit card can expect a score approximately 7-8 months after account opening.
Installment loans such as auto loans, student loans, and personal loans are generally reported to bureaus within 30-60 days of the first payment due date. Mortgage accounts follow a similar timeline. For VantageScore, which requires only one month of history, a score could appear as early as 60-90 days after the first account is opened.
Consumers who open multiple account types simultaneously may see faster score growth due to credit mix benefits. FICO's credit mix category (10% of the score) rewards having both revolving and installment accounts. However, opening multiple accounts at once generates multiple hard inquiries, which can temporarily reduce the score by 5-10 points per inquiry for approximately 12 months.

Preguntas frecuentes
There is no minimum age for having a credit score. A minor added as an authorized user on a parent's credit card can have a score generated once the account meets minimum reporting requirements (6 months for FICO, 1 month for VantageScore). To independently open a credit card, the CARD Act requires consumers to be at least 21, or 18 with proof of independent income or a cosigner.
There is no universal starting score. The initial score depends on the characteristics of the first reported accounts. A consumer with a single on-time secured card after six months typically receives an initial FICO score between 630 and 670. Consumers whose first reported item is a negative entry such as a collection will see initial scores well below 600.
Yes, through authorized user status. When a parent or guardian adds a minor to their credit card account, that card's full payment history and account age can appear on the minor's credit report. This is the primary way consumers under 18 establish credit history.
Older consumers tend to have longer credit histories (15% of FICO), more accounts contributing to credit mix (10% of FICO), higher total credit limits producing lower utilization (30% of FICO), and decades of on-time payments (35% of FICO). These factors compound over time, but the scoring models do not award points for age itself.
