Barcelona have already raked in €35.55 million from this season's run to the Champions League.
With warnings of limited transfer funds this summer, Barca's success in the summer market could depend on victory at Wembley against Manchester United.
An extra €4.5 million will be due should Barca win the final, with another €10-20 million due from UEFA over its share of television rights revenue. A further €2.5 million would also come from the European Super Cup next season.
However, running against all the above are the bonuses due to the players for such success - with estimates suggesting €50 million due to the squad should they complete a La Liga and Champions League Double.
