📘 About the Balance Transfer Calculator

A balance transfer moves debt from a high-interest card to a new card with 0% or low interest for a set period, usually 12 to 24 months, for a one-off fee of 2–5% of the balance.

The saving is the interest you no longer pay, minus the fee. To get the full benefit, pay the balance off before the promotional rate ends.

❓ Frequently asked questions

Is a balance transfer worth it?

Usually, if the interest you save is more than the fee and you can clear most of the balance in the promo period.

Does a balance transfer hurt my credit score?

The application causes a small, temporary dip; lower interest helps you pay down debt faster.

Can I transfer a balance between cards from the same bank?

Usually not — the new card must be from a different issuer.

What happens when the 0% period ends?

Any remaining balance starts charging the card's standard APR.
