Questions you'll answer

Mo buys shopping on day 1 of a 30-day statement period. The bill is due 25 days after the statement. How long until he must pay, interest-free, if he clears it in full?

Quick facts

  • Shopping, with the full statement balance paid by the due date → No interest. That's the interest-free deal working as designed.
  • Taking cash out of a cash machine on the credit card → Interest charged. Cash withdrawals usually cost a fee AND interest from day one.
  • Shopping, then paying only half the statement balance → Interest charged. On most cards, not clearing it in full means interest on purchases.
  • A train ticket, cleared in full by direct debit → No interest. Direct debit for the full balance = no purchase interest.
  • Paying the full balance two days after the due date → Interest charged. Late means interest, a late fee and a mark on your file.
  • Fact: “Cash withdrawals on a credit card usually come with a fee and interest from day one.” — No interest-free days for cash. It can also show on your credit file as a cash advance.
  • Myth: “If you pay part of the balance, the interest-free period still covers every purchase.” — On most cards, anything less than the full balance means interest. Check your card's terms.
  • Myth: “Every purchase gets exactly the same number of interest-free days.” — It depends on when in the statement month you buy: early buys get longer.
