No matter how you pay for college, understanding basic financial concepts is important. This includes liquidity, risk, interest/returns, inflation, taxes, financial aid impact, and fees. Liquidity refers to how easy it is to access money from an account. Risk is the chance of losing money. Interest and returns are money earned over time. Inflation measures rising prices, so returns should exceed inflation. Accounts are taxed differently and can affect aid. Always ask about fees, penalties, minimums and maximums when choosing accounts. Getting informed helps make the best choices.
