Most balance transfer offers require a different card issuer than your current one, and the fee is usually added to your new balance.

💳 What Is a Balance Transfer Calculator?
A balance transfer calculator compares two paths for paying off credit card debt: staying on your current card at its regular interest rate, or moving the balance to a new card offering a temporary low or 0% introductory APR. Transferring usually comes with a one-time fee — typically 3-5% of the amount moved — so the real question isn't whether 0% sounds better than 22%, it's whether the interest you'd save actually outweighs that fee, and whether you can realistically pay it off before the introductory rate expires.
🖱️ Try It Yourself: Three Real Scenarios
Click any scenario below to load it into the calculator above and see the real numbers instantly.
An $8,000 balance at 22.99% APR, transferred to a card with a 3% fee and 18-month 0% intro period, paid at $500/month. The transfer clears in 17 months and costs just the $240 fee — zero interest. Staying on the original card takes 20 months and costs $1,645.54 in interest. Transferring saves about $1,405.54.
Same $8,000 balance and 3% fee, 18-month 0% intro period — but instead of comparing, solve for the exact payment needed to hit zero right as the intro period ends. The required payment comes out to about $457.78/month, guaranteeing zero interest paid on the entire balance.
A $3,000 balance at 26.99% APR, transferred with a 5% fee to a shorter 12-month 0% offer, paid at $200/month. Even with a higher fee percentage and shorter window, transferring still meaningfully outperforms staying — load this example to see exactly by how much.
🔢 Formula Used
The intro APR applies for the stated number of months, after which any remaining balance switches to the post-intro APR for the rest of the payoff — this calculator simulates that month by month rather than assuming a single flat rate for the whole payoff, since real balance transfer cards work exactly this way.
👥 Who This Is For
- Anyone carrying credit card debt at a high APR considering a 0% transfer offer
- People comparing multiple transfer offers with different fees and intro lengths
- Anyone wanting a target payment that guarantees full payoff before interest kicks back in
- Credit counselors and planners quantifying the real benefit of a transfer for a client

What is a balance transfer fee?
A one-time charge, typically 3-5% of the amount transferred, added to your new card's balance. A $10,000 transfer at 3% adds $300 to what you owe.
Is a balance transfer worth it if I have a fee?
Usually yes, if interest saved during the intro period exceeds the fee. On a large balance at a high APR, the fee is often recovered within the first month or two of the 0% period.
What happens if I don't pay off the balance before the intro period ends?
Any remaining balance starts accruing interest at the post-intro APR, which can be as high as or higher than a typical card's standard rate — quickly eroding the benefit.
Does a balance transfer hurt my credit score?
Opening a new card causes a small, temporary dip from the inquiry. Successfully paying down debt through a transfer typically improves your score over time by lowering utilization.
Can I transfer a balance between two cards from the same bank?
Most issuers do not allow this — the transfer generally needs to move debt to a different card issuer.
How long do 0% intro APR offers typically last?
Common intro periods range from 12 to 21 months, with longer offers usually reserved for stronger credit profiles.
