Introduction
Darnell's credit card debt is a classic example of a mathematical problem that requires a deep understanding of interest rates, minimum payments, and the concept of amortization. In this article, we will delve into the details of Darnell's credit card debt and provide a step-by-step analysis of how his debt accumulates over time.
The Credit Card Terms
Darnell's credit card has an APR (Annual Percentage Rate) of 19%, calculated on the previous monthly balance. This means that if Darnell has a balance of $100 at the end of the month, he will be charged 1.58% of $100 (19% / 12) as interest for the next month. The minimum payment is 2% of the previous month's balance, which is a relatively low payment compared to the interest rate.
The Credit Card Record
The credit card record for the last 7 months is shown below:
| Month | Balance | Interest | Minimum Payment | Balance After Payment |
|---|---|---|---|---|
| 1 | $100 | $1.58 | $2 | $98.42 |
| 2 | $98.42 | $1.55 | $1.96 | $96.47 |
| 3 | $96.47 | $1.53 | $1.93 | $94.55 |
| 4 | $94.55 | $1.50 | $1.89 | $92.66 |
| 5 | $92.66 | $1.48 | $1.85 | $90.81 |
| 6 | $90.81 | $1.45 | $1.81 | $89.00 |
| 7 | $89.00 | $1.42 | $1.78 | $87.22 |
Calculating the Total Interest Paid
To calculate the total interest paid, we need to add up the interest charges for each month.
| Month | Interest | Total Interest |
|---|---|---|
| 1 | $1.58 | $1.58 |
| 2 | $1.55 | $3.13 |
| 3 | $1.53 | $4.66 |
| 4 | $1.50 | $6.16 |
| 5 | $1.48 | $7.64 |
| 6 | $1.45 | $9.09 |
| 7 | $1.42 | $10.51 |
The total interest paid is $10.51.
Calculating the Total Amount Paid
To calculate the total amount paid, we need to add up the minimum payments for each month.
| Month | Minimum Payment | Total Amount Paid |
|---|---|---|
| 1 | $2 | $2 |
| 2 | $1.96 | $3.96 |
| 3 | $1.93 | $5.89 |
| 4 | $1.89 | $7.78 |
| 5 | $1.85 | $9.63 |
| 6 | $1.81 | $11.44 |
| 7 | $1.78 | $13.22 |
The total amount paid is $13.22.
Conclusion
Darnell's credit card debt is a classic example of how interest rates and minimum payments can lead to a never-ending cycle of debt. By analyzing the credit card record, we can see that the total interest paid is $10.51, while the total amount paid is $13.22. This means that Darnell is paying $2.71 more than the minimum payment required to pay off the principal balance.
Recommendations
Based on the analysis, we recommend that Darnell:
- Pay more than the minimum payment each month to reduce the principal balance and interest charges.
- Consider consolidating his debt into a lower-interest credit card or loan.
- Avoid using credit cards for discretionary purchases and focus on paying off the principal balance as quickly as possible.
By following these recommendations, Darnell can avoid the pitfalls of credit card debt and achieve financial stability.
Mathematical Concepts
This problem involves several mathematical concepts, including:
- Interest rates: The APR of 19% is calculated on the previous monthly balance, resulting in an interest charge of $1.58 for the first month.
- Amortization: The minimum payment of 2% of the previous month's balance is used to pay off the principal balance, while the interest charge is added to the balance.
- Compound interest: The interest charge is calculated on the previous month's balance, resulting in a compounding effect that increases the balance over time.
Real-World Applications
This problem has real-world applications in the following areas:
- Personal finance: Understanding credit card debt and interest rates is essential for making informed financial decisions.
- Business finance: Companies use credit cards and loans to finance their operations, and understanding interest rates and amortization is crucial for managing debt.
- Economics: The concept of compound interest has far-reaching implications for economic growth and development.
