Introduction
In today's digital age, credit cards have become an essential part of our financial lives. However, with the convenience of credit cards comes the risk of accumulating debt and high interest charges. In this article, we will delve into the world of credit card APR (Annual Percentage Rate) and billing cycle, and explore how they impact our financial decisions.
What is APR?
APR is the interest rate charged on a credit card account over a year. It is expressed as a yearly rate, but the interest is charged on a monthly basis. In the case of Hannah's credit card, the APR is 11.90%. This means that if Hannah carries a balance of $100 on her credit card for a year, she will be charged an interest of $11.90.
What is a Billing Cycle?
A billing cycle is the period of time between two consecutive billing statements. It is usually 30 days, but can vary depending on the credit card issuer. In Hannah's case, the billing cycle is 30 days. This means that her credit card statement will be generated every 30 days, and she will be charged interest on her outstanding balance for the previous 30 days.
Hannah's Transactions in April
The following table shows Hannah's transactions in the month of April:
| Date | Amount ($) |
|---|---|
| April 1 | 100 |
| April 5 | -50 |
| April 10 | 200 |
| April 15 | -75 |
| April 20 | 150 |
| April 25 | -100 |
| April 30 | 250 |
Calculating the Outstanding Balance
To calculate the outstanding balance, we need to add up all the transactions in the table. The total amount of transactions is:
100 - 50 + 200 - 75 + 150 - 100 + 250 = 475
Since the billing cycle is 30 days, we need to calculate the interest charged on the outstanding balance for the previous 30 days. The interest rate is 11.90% per year, which is equivalent to 0.989% per month.
Calculating the Interest Charged
To calculate the interest charged, we need to multiply the outstanding balance by the interest rate. The interest charged is:
475 x 0.00889 = 4.21
Calculating the New Balance
The new balance is the sum of the outstanding balance and the interest charged:
475 + 4.21 = 479.21
Conclusion
In this article, we have explored the concept of APR and billing cycle, and how they impact our financial decisions. We have also calculated the outstanding balance, interest charged, and new balance for Hannah's credit card transactions in April. By understanding these concepts, we can make informed decisions about our credit card usage and avoid accumulating debt.

Q: What is APR, and how is it calculated?
A: APR (Annual Percentage Rate) is the interest rate charged on a credit card account over a year. It is calculated by dividing the annual interest rate by 12 (the number of months in a year). For example, if the annual interest rate is 11.90%, the monthly interest rate would be 0.989% (11.90% / 12).
Q: What is a billing cycle, and how does it affect my credit card balance?
A: A billing cycle is the period of time between two consecutive billing statements. It is usually 30 days, but can vary depending on the credit card issuer. During the billing cycle, interest is charged on the outstanding balance, and the balance is updated on the next billing statement.
Q: How is interest charged on my credit card balance?
A: Interest is charged on the outstanding balance at the end of the billing cycle. The interest rate is applied to the outstanding balance, and the result is added to the balance.
Q: Can I avoid paying interest on my credit card balance?
A: Yes, you can avoid paying interest on your credit card balance by paying the full balance in full each month. This is known as a "zero-balance" or "no-interest" payment.
Q: What happens if I don't pay my credit card balance in full each month?
A: If you don't pay your credit card balance in full each month, you will be charged interest on the outstanding balance. The interest rate will be applied to the outstanding balance, and the result will be added to the balance.
