2 Credit Cards Payoff Calculator

Reviewed by Calculator Editorial Team

Managing two credit cards can be overwhelming, but our 2 credit card payoff calculator helps you create a clear plan to pay them off efficiently. Whether you're using the debt snowball or debt avalanche method, this tool will show you the best approach based on your balances and interest rates.

How to Use This Calculator

Using our 2 credit card payoff calculator is simple:

  1. Enter the current balance for each of your two credit cards
  2. Input the interest rate for each card (APR)
  3. Specify your monthly payment amount
  4. Choose your preferred payoff strategy (snowball or avalanche)
  5. Click "Calculate" to see your payoff timeline

The calculator will show you how long it will take to pay off each card and the total time to pay off both. It also provides a visual chart showing your progress over time.

Best Payoff Strategies

There are two main strategies for paying off multiple credit cards:

Debt Snowball Method

The debt snowball method involves paying the minimum amount on all your debts except the smallest one, which you pay as much as possible toward. Once that smallest debt is paid off, you roll that payment into the next smallest debt and repeat the process.

Pros: Psychological boost from seeing debts disappear quickly, motivation to keep going

Cons: Higher total interest paid compared to avalanche method

Debt Avalanche Method

The debt avalanche method focuses on paying off the debt with the highest interest rate first, then the next highest, and so on. This method typically results in paying less interest over time.

Pros: Lower total interest paid, faster overall payoff

Cons: Can be demotivating to see larger debts remain unpaid for longer

Our calculator helps you compare both methods to see which works best for your situation.

Worked Example

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

Card Balance APR
Card A $3,000 18%
Card B $5,000 24%

Using the debt avalanche method with a monthly payment of $500:

  1. First pay off Card B ($5,000 at 24% APR) in about 11 months
  2. Then apply the $500 payment to Card A ($3,000 at 18% APR)
  3. Card A will be paid off in about 7 months
  4. Total payoff time: 18 months

Using the debt snowball method with the same $500 payment:

  1. First pay off Card A ($3,000 at 18% APR) in about 7 months
  2. Then apply the $500 payment to Card B ($5,000 at 24% APR)
  3. Card B will be paid off in about 11 months
  4. Total payoff time: 18 months

In this example, both methods take the same total time, but the avalanche method pays off more interest over the life of the debt.

Formula Explained

The calculator uses the following formula to determine payoff time for each card:

Payoff Time (Months) = -ln(1 - (Balance × (APR/1200))) / ln(1 + (Monthly Payment - (Balance × (APR/1200)))/Balance)

Where:

  • Balance = Current balance of the credit card
  • APR = Annual Percentage Rate (as a percentage)
  • Monthly Payment = Your regular monthly payment

The calculator applies this formula iteratively to each card based on your selected payoff strategy.
