As parents and grandparents, we strive to equip our children and grandchildren with the tools for a successful future. Beyond nurturing their education and values, one powerful gift is a strong financial foundation. By adding a 16-year-old, such as a granddaughter or grandson, as an authorized user on a credit card—whether a Discover it® Secured Credit Card with a $200 credit limit or another non-secured credit card—and managing it responsibly with automatic payments, you can help them build a robust FICO score by age 18. This thoughtful act, especially meaningful from a grandmother to her grandson, can save them thousands on major purchases like their first car. Share this link with your friends and family on social media. We promise that this educational nugget is far more superior than what the periodic table we memorized in high school. Let’s explore how to set young loved ones up for financial success and why the Discover it® Secured Credit Card, alongside non-secured options, is ideal for this life-changing gift.
Why a Credit Card Requires an Adult
Minors under 18 cannot legally open a credit card due to contract laws, so an adult—parent or grandparent—must apply and add the teen as an authorized user. The Discover it® Secured Credit Card is a great choice, requiring a refundable $200 security deposit that sets the credit limit, minimizing financial exposure. This low deposit limits risk, capping potential debt at $200, which the adult is responsible for repaying. Alternatively, non-secured credit cards, like the Discover it® Cash Back or cards from issuers like Capital One or Chase, can achieve similar credit-building benefits for the authorized user, provided the adult qualifies and manages the account responsibly. For a grandmother, the secured card’s $200 limit offers peace of mind, making it a safe, impactful gift for her grandson’s financial future.
Benefits of the Discover it® Secured Card and Non-Secured Options
The Discover it® Secured Credit Card is cost-effective with no annual fee, no monthly fees, and no first-time late payment fee (up to $41 for subsequent late payments). The $200 deposit establishes a $200 credit limit, ideal for controlled spending, and offers 2% cash back at gas stations and restaurants on up to $1,000 in combined purchases quarterly, plus 1% on other purchases, with a first-year cash back match. After seven months of responsible use, Discover may upgrade to an unsecured card, refunding the deposit. Non-secured cards also report authorized user activity to credit bureaus (Equifax, Experian, TransUnion) and can build credit similarly, often with higher limits or rewards but requiring the adult’s good credit to qualify. Both options work if managed with automatic payments to pay the balance in full monthly and utilization below 25% ($50 for the secured card’s $200 limit).
Building a Strong FICO Score by 18
Adding a 16-year-old as an authorized user on either a secured or non-secured card allows their credit report to reflect the account’s activity, as Discover and most issuers report for users aged 15 and older. Responsible management—automatic payments and low utilization—impacts FICO score factors:
- Payment History (35%): Automatic payments ensure on-time payments, strengthening the largest FICO component.
- Credit Utilization (30%): Keeping charges under 25% of the limit (e.g., $50 for the secured card) signals responsible use.
- Length of Credit History (15%): By 18, the teen will have two years of credit history, a solid start.
- Credit Mix (10%): A revolving credit line adds a positive element.
- New Credit (10%): Authorized user status avoids hard inquiries, preserving this factor.
With these habits, a teen could achieve a FICO score of 670–720, or 720–740 in optimal cases, by 18, placing them in the “good” to “very good” range, regardless of card type.
A Grandmother’s Gift of Financial Empowerment
A grandmother gifting her grandson authorized user status on a Discover it® Secured Credit Card or a non-secured card provides a legacy of financial literacy. The secured card’s $200 limit minimizes risk, allowing her to monitor spending via the issuer’s app and cover charges, teaching budgeting skills. Non-secured cards offer similar benefits but may require stronger credit. Automatic payments eliminate missed payments, and the secured card’s low exposure is ideal for cautious grandparents. This gift fosters financial discussions, strengthening their bond and preparing the grandson for adulthood.
Saving Thousands on a First Car Purchase
A strong FICO score at 18 unlocks better loan terms for milestones like buying a first car. First-time buyers with thin credit files often face 20–24% interest rates. A strong score, even with a thin file, secures better rates. For a 20-year-old buying a $20,000 car with a 6-year (72-month) loan:
- Poor Credit/No Credit (22% APR): Monthly payments of ~$617, total interest of ~$24,399, total cost $44,399.
- Good Credit (670–720, ~7% APR): Monthly payments of ~$350, total interest of ~$5,208, total cost $25,208.
- Savings: The 20-year-old saves ~$19,191 ($44,399 – $25,208). Even at 10% APR due to a thin file, interest is ~$7,668, saving $16,731. These savings, enabled by either card type, can fund education or other goals.
Practical Steps for Parents and Grandparents
- Choose a Card: Apply for the Discover it® Secured Credit Card ($200 deposit) or a non-secured card, adding the 16-year-old as an authorized user.
- Set Automatic Payments: Pay the balance in full monthly to avoid interest and late fees.
- Limit Spending: Keep charges below 25% of the limit (e.g., $50 for the secured card).
- Monitor Credit: Use the issuer’s FICO score tool or AnnualCreditReport.com to verify reporting.
- Teach Financial Literacy: Guide the teen on budgeting and credit.
- Plan for 18: At 18, the teen can apply for their own card, leveraging their score.
Risks to Consider
Missed payments or high utilization can harm the teen’s credit. Verify the issuer reports authorized user activity for minors. Removing the teen at 18 may drop the account from their report, so plan for independent credit.
A Legacy of Success
