What is a 0% purchase credit card and how is it different from a 0% balance transfer card?

Full answer

0% purchase cards and 0% balance transfer cards are frequently confused, but they serve distinct purposes and it is important to choose the right type for what you actually need. **What a 0% purchase card is for** A 0% purchase card allows you to buy things -- a large one-off purchase like furniture or a holiday, or simply everyday spending -- without paying interest on that spending for a set introductory period, commonly ranging from several months to a few years depending on the card and current market offers. This is useful for spreading the cost of a planned purchase interest-free, provided you have a plan to repay it within the promotional window. **How it differs from a balance transfer card** A 0% balance transfer card is designed to move existing debt already sitting on another credit card onto the new card at 0% interest -- it is a debt management tool for existing balances, not a facility for new spending. Many balance transfer cards charge a much higher rate (or no 0% period at all) on new purchases made on the same card, so using a balance transfer card for everyday spending can be a costly mistake if you assume the same 0% rate applies. **Cards offering both** Some credit cards offer separate 0% periods for both purchases and balance transfers on the same card -- but these periods, and any associated fees, can differ, so always check the specific terms for each type of transaction rather than assuming they are identical. **Discipline is essential** As with any 0% promotional card, the interest-free period only genuinely saves you money if you clear the balance before it ends -- once the introductory period expires, any remaining balance reverts to the card's standard purchase interest rate, which can be significantly higher than typical unsecured loan rates. **Using a 0% purchase card well** Calculate the total cost of your planned purchase, divide it by the number of months in the 0% purchase period, and aim to pay at least that amount each month, so the full balance is cleared before the promotional rate ends and no interest is ever paid. **Worked example** Someone buys a £1,800 sofa using a card offering 0% on purchases for 18 months. By paying £100 per month, they clear the balance in full within the interest-free window, effectively spreading the cost with no interest charged at all. **Practical tip** Set up a reminder a month or two before your 0% purchase period ends, so you have time to either clear the remaining balance or plan a balance transfer to a new 0% card if needed.
