celokupno

1. (to the full extent) entirely; wholly; as a whole
   Osiguranje je celokupno nadoknadilo štetu. — The insurance company covered the damage in full.
   Celokupno gledano, sezona je bila uspešna. — Taken as a whole, the season was a success.

The adverb celokupno is rare; u celosti or potpuno are the usual choices. The adjective celokupan ("entire, whole") is far more common: celokupno stanovništvo.
