Is a Balance Transfer Worth It?
A 0% balance transfer card lets you move existing credit card debt to a new card and pay zero interest for an introductory period — typically 12 to 30 months. Every pound you pay during this window reduces principal directly, making it one of the most powerful tools for accelerating debt payoff.
Understanding the Transfer Fee
Most balance transfer cards charge a one-off fee of 1–3% of the transferred amount. On a £4,000 balance with a 3% fee, you pay £120 upfront (added to the balance). However, if your current card is charging 22.9% APR on that balance, you may pay £800+ in interest over the same period — making the transfer fee clearly worthwhile.
The Break-Even Point
The break-even point is the number of months after which the interest savings from the transfer exceed the fee paid. This calculator helps you find it automatically. If your break-even is month 4 of a 24-month deal, the transfer almost certainly makes sense.
The Revert Rate Trap
After the introductory period ends, any remaining balance reverts to the card's standard APR — often 20–30%, higher than your original card. Ensure you either: (a) clear the full balance before the intro period ends, or (b) transfer again to a new deal. Set a calendar reminder 2 months before the intro expires.
Balance Transfers vs Debt Consolidation Loans
If your credit score qualifies you for a low-rate personal loan (e.g., 6–10% APR), that may be more predictable than a balance transfer — no revert rate risk and a fixed monthly payment. Use our Credit Card Payoff Calculator and Debt Payoff Planner to compare scenarios.
