Introduction

Credit card consolidation is a common financial strategy used by individuals to manage their debt by combining multiple balances into one lower-interest loan. In this article, we will explore the mathematical concept behind credit card consolidation and provide a step-by-step guide on how to consolidate two credit card balances into one.

Brandon's Credit Card Situation

Brandon has two credit cards with the following information:

Credit Card	Balance	Interest Rate
Card A	$2,000	18%
Card B	$1,500	12%

Brandon wants to consolidate the two balances into one balance on the card with the lower interest rate, which is Card B with an interest rate of 12%.

Mathematical Formulation

Let's denote the balance on Card A as $A$ , the balance on Card B as $B$ , and the interest rate on Card A as $r_A$ and on Card B as $r_B$ . The total balance to be consolidated is $A + B$ .

The interest paid on Card A per month is given by:

I_A = A \times r_A \times \frac{1}{12}

Similarly, the interest paid on Card B per month is:

I_B = B \times r_B \times \frac{1}{12}

The total interest paid per month on both cards is:

I_{total} = I_A + I_B = A \times r_A \times \frac{1}{12} + B \times r_B \times \frac{1}{12}

Consolidation Strategy

To consolidate the two balances into one, Brandon will pay off the balance on Card A and transfer the remaining balance to Card B. The new balance on Card B will be:

B_{new} = B + A

The interest rate on the new balance will be the interest rate on Card B, which is 12%.

The interest paid on the new balance per month is:

I_{new} = B_{new} \times r_B \times \frac{1}{12} = (B + A) \times r_B \times \frac{1}{12}

Comparison of Interest Paid

Let's compare the total interest paid per month on both cards before consolidation and after consolidation:

Before consolidation:

I_{total} = A \times r_A \times \frac{1}{12} + B \times r_B \times \frac{1}{12}

After consolidation:

I_{new} = (B + A) \times r_B \times \frac{1}{12}

Since $r_B < r_A$ , the interest paid per month after consolidation is less than the total interest paid per month before consolidation.

Conclusion

Credit card consolidation is a mathematical concept that involves combining multiple balances into one lower-interest loan. By using the mathematical formulation and consolidation strategy outlined in this article, Brandon can consolidate his two credit card balances into one balance on the card with the lower interest rate, resulting in lower interest paid per month.

Benefits of Credit Card Consolidation

Credit card consolidation offers several benefits, including:

Lower interest paid per month
Simplified payment schedule

Real-World Example

Let's consider a real-world example of credit card consolidation. Suppose John has two credit cards with the following information:

Credit Card	Balance	Interest Rate
Card A	$3,000	20%
Card B	$2,000	15%

John wants to consolidate the two balances into one balance on the card with the lower interest rate, which is Card B with an interest rate of 15%.

Using the mathematical formulation and consolidation strategy outlined in this article, John can consolidate his two credit card balances into one balance on Card B, resulting in lower interest paid per month.
