Let's say you have a debt of $14,000, which you move to a new card that doesn't charge a balance transfer fee and has a 0% intro APR on balance transfers for six months. During the promotional period, you're able to pay the debt down to $11,000. Now that it's over, you'll start paying a 19% variable APR.
Here's how much you could save by transferring the balance again, assuming:
A 3% balance transfer fee is charged.
You're able to pay the debt down to $6,000 during the intro period.
The balance transfer fee brings the total debt to $11,330. That means it would take $5,330 to pay it down to $6,000.
Had you paid interest on the previous card during those six months, it would've run about $900. Meaning once you account for the balance transfer fee, the second transfer will have saved you about $570.
