Balance transfers

💳 Credit Cards · 4 min read · Last reviewed 2026-10-02 · By the AlfaFinances editorial team

A balance transfer moves existing debt from a high-interest card onto a new card offering 0% (or a reduced rate) for a promotional period, so more of your payment goes toward the actual debt instead of being eaten by interest. There's usually a one-off transfer fee, commonly a percentage of the amount moved, so it's worth checking whether the interest saved outweighs that fee, for any meaningful balance, it very often does.

A worked example

Moving a $5,000 balance from a card charging 24% APR onto a new card offering 0% for 18 months, with a 3% transfer fee ($150), means you pay that one-off $150 fee but then pay zero interest on the $5,000 for a year and a half, versus potentially $900+ in interest over the same period on the original card. The transfer fee is a small cost compared to what continuing to carry the debt at 24% would have cost.

Key takeaways

Balance transfers redirect your payments toward the actual debt instead of interest, for a limited window.
A transfer fee (often 1-5% of the amount moved) applies, but usually still saves money versus continuing to pay high interest.
The promotional rate is temporary, treat the end date as a hard deadline to be debt-free on that amount.

Common mistakes

Not comparing the transfer fee against the interest actually being saved before assuming it's worth it.
Missing the transfer window, many offers only apply if you transfer within a limited period after opening the new card.
Continuing to add new spending on the old card after transferring the balance, undermining the whole point.

Test yourself

1. What does a balance transfer do?

Deletes your debt entirely
Moves existing debt to a new card, usually with a reduced/0% promotional rate
Increases your interest rate
Closes your old account automatically

Answer: Moves existing debt to a new card, usually with a reduced/0% promotional rate. A balance transfer moves debt to a card offering better promotional terms, redirecting payments toward the principal.

2. What cost is typically involved in a balance transfer?

No cost at all, ever
A one-off transfer fee, often a percentage of the amount moved
A monthly subscription fee
A tax to the government

Answer: A one-off transfer fee, often a percentage of the amount moved. Most balance transfers involve a one-time fee, commonly 1-5% of the transferred amount.

3. Why is the promotional period end date important?

It isn't important
Any remaining balance typically starts accruing interest at the standard rate after that date
The card is cancelled on that date
You get a bonus on that date

Answer: Any remaining balance typically starts accruing interest at the standard rate after that date. The promotional rate is temporary, after it ends, standard (often much higher) interest applies to whatever balance remains.
