If you try to use your debit card when there is not enough money in your account to cover the transaction and your account  can allow overdrawing to pay later without interest.

If your bank does pay your overdraft, you will  not be charged a hefty fee for each overdraft transaction.

If the limit is overdrawn, the borrower pays a penalty interest rate.

Select the current account you would like to see the overdraft limit for.

Even if your current account is always in credit, it can be a good idea to have an overdraft facility arranged with your bank.
