How to make calculated column with values based from result of substring search

Hi!

I've kind of painted myself into a corner. I have a table containing

SELECT [DepositID]
      ,[OrderTicket]
      ,[DepositTime]
      ,[OrderTypeNumber]
      ,[OrderProfit]
      ,[OrderComment]
      ,[DateKey]
  FROM [dbo].[Deposits]

I need a new calculated column named IsFee, and to automatically set that column to true if the word "Fee" is found anywhere in the OrderComment field, else false. OrderComment is of type varchar(27,null).

TIA!
