Balance Transfer

Plain-English definition of Balance Transfer — part of our borrowing glossary.

By · Updated · Methodology

Definition

Moving a credit card balance to a new card — typically with a promotional 0% APR window of 12–30 months and a small transfer fee (2–4%). Almost always worth doing if you can clear the balance inside the 0% period.

Worked example

Moving £4,000 of credit card debt onto a 21-month 0% card with a 3% fee costs £120 upfront. At the old 22% APR, you would have paid roughly £700+ of interest over the same period — net saving around £580.

Why it matters

Borrowing costs compound fast. A few percentage points of APR, or a few months of faster payoff, can change the total cost of a debt by thousands of pounds over its lifetime. Understanding the mechanics before you sign lets you choose the cheapest credible option rather than whatever is advertised first.

Common mistake

The most common mistake is comparing monthly payments instead of total cost. A lower monthly payment usually means a longer term and more total interest. Always compare the total amount paid over the full term, not just the headline monthly figure.
