Quick Answer
A balance transfer moves credit card debt from a high-interest card (20–29% APR) to a new card with 0% APR for 15–21 months. Transfer fees are 3–5%. On $8,000 in debt, you save $1,500–$2,500 in interest over the promo period. Divide $8,000 by the promo months to calculate required payments: $8,000 ÷ 18 months = $444/month to be debt-free.
Key Takeaways
- Balance transfer cards offer 0% APR for 15–21 months — saving hundreds or thousands in interest.
- Transfer fees are typically 3–5% ($300–$500 on $10,000) — still far cheaper than 22% APR.
- Divide your balance by the promotional months to get your required monthly payment.
- Never make new purchases on a balance transfer card — they usually accrue interest immediately.

If you carry credit card debt at 20%+ APR, a balance transfer is one of the fastest ways to stop bleeding interest and accelerate payoff. The strategy is simple: move your debt to a 0% APR card and pay it off before the promotional period ends.
How Balance Transfers Work
The step-by-step process:
- 1. Apply for a balance transfer card (requires 670+ credit score for best offers)
- 2. Request transfer of your existing balance(s) to the new card — typically within 60 days of opening
- 3. Pay the transfer fee: 3–5% added to your balance (e.g., $300 on $10,000)
- 4. Make fixed monthly payments to eliminate the balance before the 0% period ends
- 5. Pay $0 in interest during the promotional period
Calculating Your Payoff Plan
The critical calculation — can you pay it off in time?
- $5,000 balance + 3% fee ($150) = $5,150 ÷ 18 months = $286/month
- $8,000 balance + 3% fee ($240) = $8,240 ÷ 18 months = $458/month
- $12,000 balance + 3% fee ($360) = $12,360 ÷ 21 months = $589/month
- If you cannot make these payments: A balance transfer still saves money even if you pay off most (not all) of the balance during the promo. But budget aggressively.
Balance Transfer Mistakes to Avoid
These errors can turn a money-saving strategy into a money pit:
- Making new purchases on the BT card: Purchases usually accrue interest immediately at the regular APR while payments apply to the 0% balance first
- Missing a payment: Some issuers cancel the 0% rate after a late payment, jumping to the penalty APR (29%+)
- Not having a payoff plan: Without monthly targets, the promo expires with a remaining balance at 20–26%
- Transferring and continuing to spend: The old card now has a zero balance — do NOT use it. Cut spending first.
- Ignoring the transfer fee: A 5% fee on frequent balance transfers adds up quickly
When NOT to Do a Balance Transfer
Skip the balance transfer if:
- Your credit score is below 650 (you will not qualify for good offers)
- You cannot commit to fixed monthly payments during the promo period
- Your debt is so large that you cannot pay off even 70% during the promo
- You have a history of running up balances on cleared cards (consolidation only works once)

Frequently Asked Questions
Can I do multiple balance transfers?
Yes, you can transfer balances from multiple cards to one balance transfer card, up to your new card's credit limit. You can also apply for a new balance transfer card when the first promo expires — though this requires maintaining good credit and is not a sustainable long-term strategy. The goal should be debt elimination, not perpetual transfers.
What happens when the 0% APR expires?
The remaining balance begins accruing interest at the card's regular APR, typically 20–26%. This is why paying off the full balance during the promo is critical. If you have a remaining balance, consider transferring it to another 0% card (if eligible) or making aggressive payments to eliminate it quickly.
Does a balance transfer close my old credit card?
No — the balance is moved, but both cards remain open. Keep the old card open (even with a zero balance) to maintain your credit history length and reduce utilization ratio. Just do not use it for new purchases until your balance transfer is fully paid off.
