Roll-Down Your Credit Card Debt Calculator

Managing credit card debt can feel overwhelming, but using a strategic approach like roll-down can help you pay it off faster while saving on interest. This calculator helps you determine the optimal roll-down strategy for your specific debt situation.

How to Use This Calculator

Enter your current credit card balance, interest rate, and minimum monthly payment. The calculator will show you how much you can save by using the roll-down strategy compared to paying the minimum balance each month.

Note: The roll-down strategy works best when you have multiple credit cards with different interest rates. You'll pay the minimum on the highest-interest card first, then roll that balance to the next card, and so on.

What Is Roll-Down Debt Strategy?

The roll-down debt strategy is a method of paying off multiple credit cards by focusing on the highest-interest debt first, then rolling that balance to the next card. This approach helps you save on interest charges while paying off your debt faster.

Key Formula: The total interest saved using roll-down is calculated by comparing the interest paid under roll-down versus paying the minimum balance on all cards each month.

How the Roll-Down Strategy Works

The roll-down strategy involves these steps:

Identify all your credit card balances and interest rates
Pay the minimum balance on the highest-interest card first
Once that card is paid off, roll the balance to the next highest-interest card
Repeat the process until all cards are paid off

This method ensures you're always paying the highest-interest debt first, which saves you the most money on interest charges.

Worked Example

Let's say you have two credit cards:

Card A: $2,000 balance, 18% APR
Card B: $1,500 balance, 15% APR

With the roll-down strategy:

Pay the minimum on Card A ($100/month)
Once Card A is paid off, roll the balance to Card B
Pay the minimum on Card B ($75/month)

This approach would save you approximately $120 in interest charges compared to paying the minimum on both cards each month.

Frequently Asked Questions

How does roll-down compare to the avalanche method?

Both methods focus on paying off high-interest debt first, but roll-down involves transferring balances between cards, while avalanche keeps all payments on the same card. Roll-down can be more efficient if you have multiple cards with different interest rates.

Can I use roll-down if I only have one credit card?

No, the roll-down strategy requires multiple credit cards with different interest rates to be effective. If you only have one card, you should focus on paying it off as quickly as possible.

What if I can't pay the minimum on the highest-interest card?

If you can't pay the minimum, you may need to consider other debt payoff strategies or negotiate with your credit card company for a temporary reduction in interest or minimum payment.
