Lesson: Understanding Credit Cards & Interest


1.​ What is a credit card?
A credit card allows you to borrow money from a bank to make purchases.
●​ You must pay the money back
●​ If you don't pay the full balance, the bank charges interest
●​ Credit cards have a credit limit (the maximum amount you can borrow)
​ Example:
​ If your credit limit is $2,000, you cannot spend more than that amount.

2.​ Key Credit Card Terms
●​ Balance – The amount you owe.
●​ Credit Limit – Maximum amount you can borrow.
●​ Minimum Payment – The smallest amount you must pay each month.
●​ Interest Rate (APR) – The percentage the bank charges for borrowing.
●​ Grace Period – The time
●​ you have to pay before interest starts.
​ Most credit cards have interest rates around 19%--25%.

3.​ How Interests Work
Interest is the cost of borrowing money.
Simple examples:
You owe $1,000
Interest rate = 20%
Interest for one year:
​ ​ ​ ​ 1000x0.20= 200
After one year, you would owe:
$1,200
But credit cards usually calculate interest monthly, which makes it grow faster.

4.​ The Minimum Payment Trap
If you only pay the minimum payment:
●​ Your debt lasts longer
●​ You pay much more in interest
●​ It can take years to pay off small amounts
​ Example:
Example:
$1,000 debt at 20% interest
If you only pay $25/month →
You could pay hundreds extra in interest.
