Welcome to the world of financial literacy! Today, we’re going to learn about something called interest, with a little help from our friend, Frankie Finance. Let’s dive in and discover how interest works and how you can calculate it!
Interest is a special kind of money. You either pay it or earn it, depending on the situation. If you borrow money from a bank or someone else, you have to pay interest. People borrow money for lots of reasons, like buying cars, houses, going on vacations, paying for college, or starting a business. Sometimes, people need to borrow money for healthcare expenses too.
But here’s the cool part: if you save money in a bank, you can earn interest! Many people open savings accounts to keep their money safe and earn a little extra through interest.
Before we calculate interest, we need to know two important terms: principal and rate. The principal is the amount of money you start with, whether you’re borrowing or saving. The rate is the percentage the bank charges you for borrowing money or pays you for saving money with them.
Now that we know what interest, principal, and rate are, let’s learn how to calculate interest using a simple equation:
Let’s see how this works with Frankie. Frankie saved $200 and put it into a savings account with an interest rate of 15% per year. How much interest will Frankie earn in one year?
First, we need to change the rate from a percentage to a decimal. So, 15% becomes 0.15.
Now, let’s use the equation:
Using the equation, we find that Frankie will earn $30 in interest after one year. If she leaves the $200 in her account for the whole year, she will have a total of $230.
Now, let’s see how much interest Frankie would earn in 5 years using the same equation. After 5 years, Frankie will earn $150 in interest, bringing her total savings to $350.
It’s important to remember that the opposite is also true. If Frankie borrowed $200 at a rate of 15% per year, she would owe $30 in interest after one year, totaling $230. If it took her 5 years to pay back the loan, she would owe an additional $150 in interest, making her total repayment $350.
Being able to calculate interest is a super useful skill in your financial literacy toolbox. Don’t forget to practice your new skills and share what you’ve learned with others!

Let’s put your new skills to the test! Create a set of different scenarios where you either save or borrow money. Calculate the interest for each scenario using the formula: Interest = Principal × Rate × Time. Share your results with the class and see who can come up with the most interesting scenario!
Write a short story about a character who either saves or borrows money. Describe how they use interest to their advantage or how it affects their decisions. Share your story with a partner and discuss what your characters learned about interest.
Imagine you are visiting a bank to open a savings account. Role-play with a classmate where one of you is the bank manager and the other is the customer. Discuss the benefits of saving money and earning interest. Make sure to ask questions about the principal and rate!
Create a visual representation of how interest works over time. Use graphs, charts, or drawings to show how money grows when saved or how debt increases when borrowed. Display your artwork in the classroom and explain your design to your classmates.
Design a board game where players earn or pay interest as they move around the board. Include spaces that represent different financial decisions, like saving money or taking out a loan. Play the game with your classmates and see who can manage their money the best!

Understanding financial literacy includes knowing what interest is and how to calculate it. Today, we will explore this concept with the help of our friend, Frankie Finance.
Simply put, interest is the amount of money you either pay or earn, depending on the situation. If you borrow money from a bank or another lender, you will have to pay interest. People borrow money for various reasons, such as purchasing cars, homes, vacations, college tuition, or starting businesses. Sometimes, borrowing is necessary for healthcare expenses.
On the other hand, if you save money at a bank, you can earn interest. Many people open savings accounts to keep their money safe while earning interest.
The amount of money you start with, whether borrowing or saving, is called the principal. Another important term is the rate, which is the percentage a bank charges you for borrowing money or pays you for saving money with them.
Now that we understand interest, principal, and rate, we can calculate interest using a simple mathematical equation. Remember this equation for simple interest:
**Interest = Principal × Rate × Time (in years)**
Let’s see how this works with Frankie. Frankie saved $200 and put it into a savings account with an interest rate of 15% per year. How much interest will Frankie earn in one year?
First, we convert the rate from a percentage to decimal format: 15% equals 0.15.
Now, we can use the equation:
– Principal = $200
– Rate = 0.15
– Time = 1 year
Using the equation, we find that Frankie will earn $30 in interest after one year. If she leaves the $200 in her account for the entire year, she will have a total of $230.
Now, let’s calculate how much interest she would earn in 5 years using the same equation. After 5 years, Frankie will earn $150 in interest, bringing her total savings to $350.
It’s important to remember that the opposite is also true. If Frankie borrowed $200 at a rate of 15% per year, she would owe $30 in interest after one year, totaling $230. If it took her 5 years to pay back the loan, she would owe an additional $150 in interest, making her total repayment $350.
