Roll Down Debt Calculator Credit Cards

Rolling down your credit card debt means transferring balances from higher-interest cards to lower-interest cards to save on interest charges. This strategy can significantly reduce the total amount you pay over time. Our calculator helps you determine exactly how much you'll save by comparing different roll down scenarios.

How Roll Down Debt Works

Credit card interest rates can vary significantly between cards. By transferring balances from higher-interest cards to lower-interest cards, you can reduce the total interest you pay. This strategy is often called "roll down debt" or "balance transfer strategy."

Key Concepts

Interest Rate Difference: The primary benefit comes from the difference in interest rates between your cards.
Balance Transfer Fees: Some cards charge a fee for balance transfers, which should be considered when calculating savings.
Minimum Payments: Paying only the minimum on high-interest cards can lead to long repayment periods and high total interest.

Interest Calculation Formula

The total interest paid can be calculated using the formula:

Total Interest = (Balance × Interest Rate × Time) / 100

Where Time is in years.

Example Scenario

Suppose you have $5,000 in debt on a card with a 20% APR and want to transfer it to a card with a 12% APR. Over 2 years, the interest saved would be:

Interest Saved = ($5,000 × 20% × 2) - ($5,000 × 12% × 2) = $2,000 - $1,200 = $800

Example Calculations

Let's look at two different scenarios to illustrate how roll down debt can save you money.

Scenario 1: High Interest Rate

Current balance: $3,000
Current APR: 24%
Transfer APR: 15%
Time: 1 year

Interest saved: $180

Scenario 2: Long Repayment Period

Current balance: $10,000
Current APR: 18%
Transfer APR: 12%
Time: 3 years

Interest saved: $1,800
