How Balance Transfer Is Calculated

Current Scenario: Simulates your current debt payoff with your current rate and payment.

Transfer Scenario:

  1. Transfer Fee = Debt Balance × (Transfer Fee % / 100)
  2. Total Transfer Balance = Debt Balance + Transfer Fee
  3. During the intro period, interest is 0%.
  4. After the intro period, interest accrues at the post-intro rate.
  5. The simulation runs month by month until the balance is paid off.

Interest Saved = Current Total Interest − Transfer Total Interest
