**Calculating Credit Card Interest: A Comprehensive Guide**

Understanding Credit Card APR and Interest Rates

When it comes to credit cards, understanding the Annual Percentage Rate (APR) and interest rates is crucial in making informed decisions about your financial transactions. In this article, we will delve into the world of credit card interest rates and explore how to calculate the interest on your credit card balance.

Introductory APR and Standard APR

Clayton transferred a balance of $\$ 4125$ to a new credit card at the beginning of the year. The card offered an introductory APR of $7.9\%$ for the first 5 months and a standard APR of $25.7\%$ thereafter. This means that for the first 5 months, Clayton will be charged an interest rate of $7.9\%$ , and after that, the interest rate will increase to $25.7\%$ .

Calculating Interest for the Introductory Period

To calculate the interest for the introductory period, we need to use the formula:

Interest = Principal x Rate x Time

Where:

Principal is the initial balance of $\$ 4125$
Rate is the introductory APR of $7.9\%$
Time is the number of months in the introductory period, which is 5 months

Plugging in the values, we get:

Interest = $\$ 4125$ x $7.9\%$ x 5 months

Interest = $\$ 4125$ x 0.079 x 5

Interest = $\$ 1625.25$

So, the interest charged during the introductory period is $\$ 1625.25$ .

Calculating Interest for the Standard Period

After the introductory period, the interest rate increases to $25.7\%$ . To calculate the interest for the standard period, we need to use the same formula:

Interest = Principal x Rate x Time

Where:

Principal is the remaining balance after the introductory period, which is $\$ 4125$ - $\$ 1625.25$ = $\$ 2499.75$
Rate is the standard APR of $25.7\%$
Time is the number of months in the standard period, which is 7 months (from month 6 to month 12)

Plugging in the values, we get:

Interest = $\$ 2499.75$ x $25.7\%$ x 7 months

Interest = $\$ 2499.75$ x 0.257 x 7

Interest = $\$ 4433.51$

So, the interest charged during the standard period is $\$ 4433.51$ .

Total Interest Charged

To find the total interest charged, we need to add the interest charged during the introductory period and the standard period:

Total Interest = $\$ 1625.25$ + $\$ 4433.51$

Total Interest = $\$ 6058.76$

So, the total interest charged on Clayton's credit card balance is $\$ 6058.76$ .

Conclusion

Calculating credit card interest can be a complex task, but by understanding the APR and interest rates, you can make informed decisions about your financial transactions. In this article, we explored how to calculate the interest on a credit card balance with an introductory APR and a standard APR. By using the formula Interest = Principal x Rate x Time, we can calculate the interest charged during each period and find the total interest charged.
