Companion summary

Have you ever wondered how a bank can actually pay you just for keeping your money safe with them? Every time someone takes out a loan or uses a credit card, interest is quietly adding up in the background. A credit card balance of 500 pounds, left unpaid, could grow to over 600 pounds in just one year with a typical interest rate. When you finish, try working out what 20 percent interest would add to a 200-pound debt — the answer might surprise you.

The Magic — and the Trap — of Percentages

Imagine you lend a friend £100 and they pay you back £110 a year later. Where did that extra £10 come from? Now flip it: you borrow £100 from someone, and a year later you owe them £110. Same maths — but very different feelings. Money has a hidden power: it can grow on its own, or it can quietly drag you deeper into trouble. Today you will find out exactly how that works.

💭 Think about this

Think of something you would really like to buy that you cannot afford right now. How might you get that money — and what could go wrong if you borrowed it?
