T-SQL - How to do subtotals?

I have a table with customers and a customertype.  I would like to get  a subtotal of the number of customer types.  Here is an example.  Note that the "Total" field is not in the database.

Type  Total
Good   100
Bad      25
Other    9

Thank you

Here is what I have done so far... IT does give a total, but not a subtotal by Type.
 
SELECT    CustType
FROM        Customer
ORDER BY CustType
COMPUTE COUNT(CustType)
