The short version
Interest is the price of using money. A saver may earn it; a borrower pays it.
Compounding means interest can be calculated on earlier interest too. That helps long-term savings but can make unpaid debt grow.
Rate, balance, time, and fees all matter. APR helps compare borrowing costs.
