A savings account is generally designed for holding money and earning modest interest, and often comes with limits on how many free withdrawals or transactions you can make per month before fees apply. A current account is built for frequent day-to-day transactions - salary deposits, bill payments, and card spending - typically without earning interest, but with unlimited or high-volume transaction allowances and sometimes an attached chequebook facility that most savings accounts don't offer.
