I don't remember where but the results of the study were like following ...
if the cost of inserting one row to a table is 1 unit and if you have 5 indexes on the table than total cost of inserting 1 row to the table is
1 (cost of inserting a row)
+ 3*5 (5 indexes)
---------
16
So total cost is about 16 units.
