How Balance Transfers Work
A balance transfer moves debt from one or more high-interest credit cards to a new card with a promotional 0% APR period. During this period - typically 12–21 months - you pay no interest on the transferred balance, allowing every payment dollar to reduce your principal.
Balance Transfer Math: $5,000 at 24% APR
Without Balance Transfer
$5,000 at 24% APR
Paying $250/month
= 26 months to pay off
Total interest: ~$1,340
With Balance Transfer (18 months 0%)
$5,000 + 3% fee = $5,150
Paying $286/month
= 18 months to pay off
Total cost: $150 fee. Savings: $1,190
Step-by-Step Balance Transfer Process
Audit your current debt
List every card, balance, and interest rate. Calculate how much you're paying monthly in interest alone.
Check your credit score
Most 0% balance transfer cards require 670+. Use our credit score simulator to assess your eligibility.
Compare offers
Look for: length of promotional period (longer is better), transfer fee percentage, and regular APR after promo ends.
Apply for the card
Apply for one card only. Multiple applications hurt your score through <InternalLink href='/glossary/hard-inquiry'>hard inquiries</InternalLink>.
Request the transfer
Once approved, initiate the balance transfer. Provide the creditor's information and amount. Allow 1–2 weeks to process.
Create a payoff plan
Divide the transferred balance by the number of promotional months. That's your minimum payment goal each month.
Set up autopay
Never miss a payment. Many issuers will cancel the promotional rate if you miss a payment.
Avoid new purchases on the transfer card
New purchases often don't qualify for the 0% rate and may have higher rates. Keep this card strictly for payoff.
When Balance Transfers Make Sense (and When They Don't)
| Good Situation | Poor Situation |
|---|---|
| You have a specific payoff plan and can pay it off within the promo period | You don't have a plan and will just accumulate more debt |
| Current APR is 15%+ and you have 670+ credit score | Current APR is already low (under 8%) |
| The fee is less than 3 months of current interest charges | You'll need to make the minimum only - promo period too short |
| You can avoid new spending on the transfer card | You plan to use the card for new purchases |
For debts too large for a balance transfer, consider a debt consolidation loan. For the optimal payoff order, see debt snowball vs. avalanche.
Frequently Asked Questions
What credit score do I need for a balance transfer card?
Most 0% APR balance transfer cards require good credit (670+). The best offers typically require 720+. If your score is lower, work on improving it first before applying.
Is there a fee for balance transfers?
Most cards charge a balance transfer fee of 3–5% of the transferred amount. On $5,000, that's $150–$250. This is usually still worth it compared to months of 20%+ interest.
What happens at the end of the promotional period?
Any remaining balance reverts to the regular APR, which is typically 19–29%. The goal is to pay off the entire balance before the promotional period ends.
