Before you invest a single dollar, build the cushion that protects you when life throws a surprise.
An emergency fund is cash set aside for surprises — a busted phone, a car repair, a sudden gap in income. It lives in a plain savings account, not investments, because you need it to be liquid: instantly reachable without selling anything at a bad time.
Here's the logic. If your money is locked in investments and an emergency hits, you're forced to sell — maybe right when prices are down — or reach for a credit card and its brutal interest. A cash cushion means a surprise stays a small annoyance instead of becoming debt.
A common target is 3 to 6 months of your basic expenses. As a teen with low expenses, even a small starter cushion (say a few hundred dollars) is a huge head start — the habit matters more than the size. Grow it toward 3 months as your expenses grow.
Your emergency fund should sit in a high-yield savings account (HYSA) — a normal savings account that pays a lot more interest than a big bank's basic one, while keeping your money instantly reachable. A few popular options:
Examples to explore, not recommendations — interest rates change constantly, so compare current ones, and open any account with a parent if you're under 18.
Set your monthly expenses, how much you can save each month, and your safety target. See your goal and how long it takes.
Once your cushion's in place, you're ready for the fun part. The rest of these lessons show you how to put money to work: buying stocks and ETFs, using retirement accounts, and letting compound interest run for decades. Your emergency fund is what lets you stay invested through scary markets without panic-selling — because your life money is safe somewhere else.
