Money in College: The Financial Skills That Prevent a

The financial decisions made between ages 18–24 set patterns that often last decades. The good news: building good patterns at 20 is far easier than recovering from bad ones at 30.

The financial priorities for college students

1. Build one credit card (single, low limit): Charge one small predictable expense (a streaming subscription). Pay it in full every month. This builds credit history that benefits you for decades. Start at 18 — age of credit accounts matters.
2. Don't take more student loans than necessary: The FAFSA shows how much you're eligible for — not how much you should take. Only borrow what's needed for tuition, fees, and essential living costs. Every $1,000 in additional loans costs $1,300–$1,800 repaid over 10 years.
3. Open a Roth IRA with any earned income: If you work during college (work-study, summer job): contribute up to your earned income to a Roth IRA. $1,000 at 20 at 7% = $29,000 at 65. This is the best investment you can make at this age.
4. Build $500 in savings before anything else: College emergencies (car repair, medical, travel home) happen. Without a buffer, they go on a credit card at 20%+ APR.

The purchases that hurt most

• Financed cars while in college: A $15,000 car loan at 12% APR = $333/month for 5 years = $4,980 in interest. On a student budget, this derails everything.
• Private student loans (not federal): Private loans have no forgiveness programs, no income-driven repayment options, and often variable rates. Borrow federal first.
• Credit card balances: The first month you carry a balance, the reward system breaks. The card now costs you money instead of earning you money.

The one financial concept every college student must understand

The opportunity cost of time. $200/month invested starting at 22 vs starting at 32 (same 30 years total contributed = $72,000): the 22-year-old has $1.1M at 65 vs the 32-year-old's $520,000. The extra 10 years of compounding is worth more than the total contributions in either scenario.
