A 0% purchase credit card charges no interest on eligible purchases for a set introductory period, provided you make at least the minimum payment on time each month. You’ll still need to repay the balance, and any amount left when the promotional period ends will usually be charged at the card’s standard rate. Check the terms for the exact end date, minimum payments and whether cash withdrawals or balance transfers are treated differently. Approval and the credit limit depend on the provider’s assessment of your circumstances.
