Enter your balance, what you can truly pay each month, and the offer you’re looking at. The calculator shows the interest saved – and more importantly, whether your repayment actually clears the debt before the 0% period ends and the revert rate (typically 20-26% p.a.) takes over. That’s the bet the bank is making against you.

New to the concept? Read what a balance transfer is and the trap most people fall into, then how to pick the right offer (hint: the longest 0% period is frequently not the cheapest). If you’re in financial difficulty, the National Debt Helpline (1800 007 007) is free and independent.
