Burnley recorded the fifth highest net profit by a European club in the financial year of 2015, ahead of the likes of Bayern Munich, Porto and Ajax.
The Clarets, who made a net profit of 40m euros in the year they were relegated from the Premier League, were one of four English teams joined in the top five by Real Madrid.
"This is a club that has to be run properly," said manager Sean Dyche.
Burnley's operating profit of 54m euros was the 10th best on the continent.
Manchester United returned the highest operating profit - their 143m euros beating the 135m Real Madrid brought in in 2011.
