A 0% APR balance transfer sounds like free money. It's not.
I had a client — Tanya — who transferred $5,000 to a 0% card. She thought she'd pay it off in 15 months. But she missed the fine print: the 0% APR was only on new purchases, not on balance transfers. She didn't notice until her first statement arrived with 22% interest on the transferred balance.
She was furious. I don't blame her. The card company had buried the condition on page 3 of the agreement, in a paragraph about "introductory rates."
Here are three traps to watch for:
1. Balance transfer fee. Most cards charge 3-5%. On $10,000, that's $300-500. That fee eats into your savings. If you're only saving 6 months of interest, the fee might wipe it out.
2. Deferred interest. Some "0%" offers actually have deferred interest. If you don't pay off the full balance before the promo ends, they charge you ALL the back interest — sometimes at 25% or more. I've seen people pay hundreds in surprise interest.
3. Payment allocation. If you transfer a balance and also make purchases, your payments typically go to the lowest APR first. So you could pay off the 0% transfer while the higher-rate purchases sit there accruing interest. It's legal. It's shady.
How to avoid these traps:
- Read the "Schumer box" (the fee disclosure table). It's required by law.
- Ask directly: "Is this deferred interest or true 0%?"
- Don't use the card for purchases if you've done a balance transfer.
- Set up auto-pay for more than the minimum to ensure you pay off the transfer in time.
Tanya ended up canceling the transfer and paying the balance transfer fee as a lesson. She paid off the original card in 10 months with a strict budget. She still has the card but never uses it.
Balance transfers can work. But read the fine print. Assume the bank is trying to trick you. Because they are.
I will keep posting updates on this. Check back soon.
P.S. I forgot to mention: Tanya also called the card company to complain. They offered to waive the fee if she paid off the balance in 90 days. She did. So sometimes complaining works. Not always. But sometimes.
