Saving vs borrowing:
Assets are everything you own that is worth money, like cash, savings, investments, real estate, and valuable items. In other words, an asset is something you own that has value. On the other hand, a liability is something you owe that is a financial obligation.
Sort the items into assets and liabilities. Remember, assets are things that you own that have value and liabilities are things you owe!
A loan is money or property that you borrow with a promise to repay the original amount, called the principal, plus extra charges like interest or fees. Loan repayments can be one-time or ongoing.
What kinds of loans are there? Explore the diagram below to discover some common types of loans.
Compound interest is interest that is calculated not just on the original loan or deposit — the principal — but also on the interest already added. This concept is often referred to as interest on interest.
In contrast, simple interest is calculated only on the principal amount.
Use this calculator to find simple or compound interest. Enter the required parameters for your specific case and choose the interest type to get the result.
Ethan buys a gaming laptop for $1000 using a credit card with a 20% annual interest rate, compounded monthly. He was offered a deal where he doesn't have to make any payments for the first year, so he doesn't.

Option | Logic | Conclusion |
---|---|---|
Pay off the full balance right away. | No balance remains to accrue interest if paid immediately. | No interest will be paid ✓ |
Buy a cheaper laptop. | A lower purchase amount reduces total interest but doesn’t prevent it from accruing. | Less interest would be paid overall × |
Pay the balance off in equal payments over the course of the year. | Interest accrues from the first month, but consistent payments reduce the balance faster. | Less interest would be paid overall × |
Negotiate with the credit card company for better terms and conditions. | A successful negotiation might lower the interest rate but won't guarantee zero interest. | Less interest might be paid × |
When borrowing money, both the interest rate and the annual percentage rate are important to understand.
The annual percentage rate (APR) represents the annual cost of borrowing money, shown as a percentage. It includes the interest rate plus any extra fees or costs associated with the loan.
Banks often advertise the interest rate instead of the APR because it's more attractive. This is because the interest rate only shows the cost of borrowing, while the APR includes interest plus fees. APR is usually higher and gives a more complete picture of the total cost of a loan. By highlighting the lower interest rate, banks make their loans appear more appealing.
Layla takes out a $10000 loan to buy her first car. She is told that the interest rate is 5%, compounded monthly, and she plans to pay it off in 5 years. She uses this number to build her budget. After reviewing her contract, she learns that there are extra fees included in the loan, which brings the annual percentage rate (APR) to 6%.

Loans can help you pay for important things — like a car, college tuition, or even a home — but only if you understand how they really work.
When you borrow money, you're not just paying back the amount you took out — you're actually paying back extra money in the form of interest and possibly fees. That's why it's so important to know:
If you don't read the fine print or don't understand these terms, you could:
Understanding loans now helps you make smarter financial decisions later, so you're in control of your money — instead of your money controlling you.
