Which Credit Card Do I Pay First Calculator

Managing multiple credit cards can be confusing, especially when deciding which one to pay first. This calculator helps you determine the optimal payment order based on interest rates, balances, and payment options.

How to Use This Calculator

To use this calculator effectively:

Enter the current balance for each credit card you want to compare
Input the interest rate for each card (APR)
Select your payment method for each card (minimum payment or full balance)
Click "Calculate" to see the recommended payment order
Review the results and chart to understand the impact of each payment strategy

This calculator assumes you'll make all payments on time and won't incur any additional fees. Results are based on the current balances and interest rates you enter.

How the Calculation Works

The calculator uses a simple but effective method to determine which card to pay first:

Calculate the interest cost for each card if you pay only the minimum payment
Calculate the interest cost for each card if you pay the full balance
Determine the difference in interest cost between these two scenarios
Rank the cards by the interest savings you'll realize by paying the full balance

Interest Cost Calculation:

Monthly interest cost = (Balance × APR ÷ 12) ÷ 100

Total interest over 12 months = Monthly interest cost × 12

The calculator then compares these values to recommend the most cost-effective payment order.

Example Calculation

Let's look at an example with two credit cards:

Card A: $1,000 balance, 18% APR
Card B: $500 balance, 24% APR

If you pay the minimum payment on both cards:

Card A: $15 interest (assuming 2% minimum payment rate)
Card B: $10 interest (assuming 2% minimum payment rate)
Total interest: $25

If you pay the full balance on Card B first:

Pay $500 to Card B (no interest)
Remaining balance: $500 on Card A
Interest on Card A: $7.50 (assuming 2% minimum payment rate)
Total interest: $7.50

In this example, paying Card B first saves you $17.50 in interest over 12 months.

Frequently Asked Questions
