What Is a Balance Transfer?
A balance transfer moves your credit card balance to a card with a lower introductory APR — often 0% for 12–21 months. That window of zero interest can save hundreds or thousands, but the transfer fee (typically 3–5%) and what happens after the intro period matter.
The calculator compares your current card with the transfer offer: interest paid on each, the fee, savings over the intro period, and what the balance costs if it is not cleared before the intro APR ends.
The Method
Both plans are simulated with the same monthly payment. The comparison shows the total interest + fee for each, and the break-even.

Frequently Asked Questions
How much does a balance transfer save?
On a $5,000 balance at 22% APR, a 12-month 0% offer with a 3% fee typically saves $800–1,000 even after the fee.
What is the transfer fee?
Usually 3–5% of the transferred amount, charged upfront by the new issuer.
What happens after the intro period?
The rate jumps to the card's regular APR (often 18–25%). The calculator shows the cost if the balance remains.
Can I transfer to the same issuer?
Most issuers do not allow transferring between their own cards.
Will a balance transfer hurt my credit?
The new card application causes a small, temporary dip; utilization changes can help or hurt — overall, transferring to pay down faster typically helps.
