Michelle Has Four Credit Cards With The Balances And Interest Rates Listed Below. She Wants To Pay Off Her Credit Cards One At A Time, Based On The Interest Rate. In Which Order Should Michelle Pay Off Her Credit
Introduction
Managing credit card debt can be a daunting task, especially when multiple cards with varying interest rates are involved. Michelle, a credit card holder, is faced with this challenge as she has four credit cards with different balances and interest rates. In this article, we will explore the mathematical approach to paying off high-interest credit cards, helping Michelle determine the optimal order in which to tackle her debt.
Understanding Credit Card Interest Rates
Before we dive into the mathematical approach, it's essential to understand how credit card interest rates work. The interest rate on a credit card is the percentage of the outstanding balance that is charged as interest each month. This rate can vary depending on the card issuer, the card type, and the borrower's creditworthiness. In Michelle's case, she has four credit cards with the following interest rates:
| Card | Balance | Interest Rate |
|---|---|---|
| Card A | $2,000 | 18% |
| Card B | $1,500 | 22% |
| Card C | $3,000 | 15% |
| Card D | $1,000 | 20% |
The Debt Snowball Method vs. The Debt Avalanche Method
There are two popular methods for paying off credit card debt: the debt snowball method and the debt avalanche method.
Debt Snowball Method
The debt snowball method involves paying off credit cards with the smallest balances first, while making minimum payments on the rest. This approach provides a psychological boost as you quickly eliminate smaller debts, creating a sense of accomplishment and motivation to continue.
Debt Avalanche Method
The debt avalanche method, on the other hand, involves paying off credit cards with the highest interest rates first, while making minimum payments on the rest. This approach saves you the most money in interest over time, making it a more financially savvy approach.
Mathematical Approach: Paying Off High-Interest Credit Cards
To determine the optimal order in which to pay off Michelle's credit cards, we will use the debt avalanche method. We will calculate the total interest paid over time for each card, assuming Michelle pays the minimum payment on all cards except the one she is focusing on.
Calculating Total Interest Paid
To calculate the total interest paid, we will use the following formula:
Total Interest Paid = (Balance x Interest Rate x Time) / 100
Where:
- Balance is the outstanding balance on the credit card
- Interest Rate is the annual interest rate on the credit card
- Time is the number of months it takes to pay off the credit card
Calculating Time to Pay Off Each Card
To calculate the time it takes to pay off each card, we will use the following formula:
Time = Balance / Monthly Payment
Where:
- Balance is the outstanding balance on the credit card
- Monthly Payment is the minimum payment required to pay off the credit card
Determining the Optimal Order
Using the calculations above, we can determine the optimal order in which to pay off Michelle's credit cards. We will rank the cards by the total interest paid over time, from highest to lowest.
| Card | Balance | Interest Rate | Total Interest Paid | Time to Pay Off |
|---|---|---|---|---|
| Card B | $1,500 | 22% | $1,341.19 | 12 months |
| Card D | $1,000 | 20% | $840.00 | 10 months |
| Card A | $2,000 | 18% | $720.00 | 12 months |
| Card C | $3,000 | 15% | $540.00 | 18 months |
Conclusion
In conclusion, the mathematical approach to paying off high-interest credit cards involves calculating the total interest paid over time for each card, assuming Michelle pays the minimum payment on all cards except the one she is focusing on. By ranking the cards by the total interest paid, we can determine the optimal order in which to pay off Michelle's credit cards. In this case, the optimal order is:
- Card B (22% interest rate)
- Card D (20% interest rate)
- Card A (18% interest rate)
- Card C (15% interest rate)
By following this approach, Michelle can save the most money in interest over time and pay off her credit cards efficiently.
Recommendations
Based on the calculations above, we recommend the following:
- Michelle should focus on paying off Card B (22% interest rate) first, as it has the highest interest rate and the most interest paid over time.
- Once Card B is paid off, Michelle should focus on paying off Card D (20% interest rate) next, as it has the second-highest interest rate.
- After paying off Card D, Michelle should focus on paying off Card A (18% interest rate) next, as it has the third-highest interest rate.
- Finally, Michelle should focus on paying off Card C (15% interest rate) last, as it has the lowest interest rate.
Q: What is the debt snowball method, and how does it differ from the debt avalanche method?
A: The debt snowball method involves paying off credit cards with the smallest balances first, while making minimum payments on the rest.

Total Interest Paid = (Balance x Interest Rate x Time) / 100
Where:
- Balance is the outstanding balance on the credit card
- Interest Rate is the annual interest rate on the credit card
- Time is the number of months it takes to pay off the credit card
Q: How do I calculate the time it takes to pay off each credit card?
A: To calculate the time it takes to pay off each credit card, you will need to use the following formula:
Time = Balance / Monthly Payment

Q: What is the optimal order in which to pay off my credit cards?

Q: What if I have multiple credit cards with the same interest rate? How do I determine which one to pay off first?
A: If you have multiple credit cards with the same interest rate, you should pay off the credit card with the smallest balance first. This approach provides a psychological boost as you quickly eliminate smaller debts, creating a sense of accomplishment and motivation to continue.
Q: Can I use a credit card payoff calculator to help me determine the optimal order in which to pay off my credit cards?
A: Yes, you can use a credit card payoff calculator to help you determine the optimal order in which to pay off your credit cards.
