What is stoozing?

Stoozing is a UK money strategy where you spend on a 0% interest credit card instead of your debit card. The money you would have spent stays in a savings account earning interest. Before the 0% period ends, you pay off the card in full. You keep the interest as profit.

How to maximise your stoozing profit

  • Use a 0% purchase card (no transfer fee) rather than a balance transfer card where possible
  • Park the money in the highest-rate easy access savings account or Premium Bonds
  • Set up a direct debit for at least the minimum payment so you never miss one
  • Set a reminder 2-3 months before the 0% period ends to pay off the balance
  • Don't overspend — only put normal spending on the card, not extra purchases

Risks to watch out for

  • Missing a minimum payment voids the 0% deal immediately — you'll pay the revert rate (typically 22-25% APR)
  • Forgetting to pay off the balance before the 0% period ends
  • Cash withdrawals on credit cards are never 0% and incur fees
  • Applying for multiple credit cards in a short period can temporarily affect your credit score
