Introduction

Dennis, a credit card holder, has an APR of 10.14% and a billing cycle of 30 days. To understand how his credit card APR and billing cycle affect his transactions, we need to analyze the data from his November transactions. In this article, we will delve into the world of credit card finance and explore how APR and billing cycle impact credit card holders.

What is APR?

APR, or Annual Percentage Rate, is the interest rate charged on a credit card account. It is expressed as a yearly rate, but it is applied monthly to the outstanding balance. In Dennis's case, his APR is 10.14%, which means that if he has an outstanding balance of $100, he will be charged $10.14 in interest over the course of a year.

How is APR Applied?

APR is applied to the outstanding balance on a monthly basis. This means that if Dennis has an outstanding balance of $100 at the end of the billing cycle, he will be charged 10.14% of $100 in interest for the next month. This interest will be added to the outstanding balance, resulting in a new balance of $110.14.

What is a Billing Cycle?

A billing cycle is the period of time between credit card statements. It is usually 30 days, but it can vary depending on the credit card issuer. During this time, credit card holders are expected to pay their outstanding balance in full or make a minimum payment. If they fail to do so, interest will be charged on the outstanding balance.

Dennis's November Transactions

The following table shows Dennis's transactions with his credit card in November:

Date	Amount ($)	Discussion category
1st	100	Purchase
5th	50	Purchase
10th	200	Purchase
15th	100	Purchase
20th	50	Purchase
25th	200	Purchase
30th	100	Purchase

Calculating Interest

To calculate the interest charged on Dennis's credit card, we need to calculate the outstanding balance at the end of the billing cycle. We will assume that the billing cycle ends on the 30th of November.

Date	Amount ($)	Outstanding Balance ($)
1st	100	100
5th	50	150
10th	200	350
15th	100	450
20th	50	500
25th	200	700
30th	100	800

As we can see, the outstanding balance at the end of the billing cycle is $800. To calculate the interest charged, we need to multiply the outstanding balance by the APR.

Interest = Outstanding Balance x APR = $800 x 0.1014 = $81.12

Conclusion

In conclusion, Dennis's credit card APR and billing cycle have a significant impact on his transactions. The APR of 10.14% means that he will be charged $81.12 in interest for the month of November. The billing cycle of 30 days means that he has 30 days to pay his outstanding balance in full or make a minimum payment. If he fails to do so, interest will be charged on the outstanding balance.
