Why does this matter?
Most schools do not teach personal finance. You graduate, get your first credit card, and suddenly you are making decisions about APR, minimum payments, and compound interest without any background.
The difference between understanding these concepts and not understanding them is often tens of thousands of dollars over your lifetime. A 5% difference in credit card APR on a $5,000 balance costs you an extra $250 per year in interest alone.
These guides are written for people in their 18s and 20s who are encountering this stuff for the first time. Every concept includes real numbers so you can see the actual impact on your money.
