Like all other qualities which increase by CP: The number of CP you need to reach the next level is equal to that level.

So, to get Renown (or any other quality) from 20 to 21 you need 21 CP. to get from 49 to 50 you need 50 CP.

The action on this page provides 28 CP for the cost of 7 Favours (plus some other items).
