Ronaldo, who boasts a following of 106million on the social network, is a prolific contributor - regularly adding multiple images each day of his excursions around the world.
And Hopper says that every time he does so, he adds a significant chunk to his already considerable riches.
Ronaldo is one of only two sportsmen in the top 10.
Basketball sensation LeBron James sits in 10th with each of his posts apparently earning him £93,000.
He and Ronaldo are the only two men on the list, with reality TV family the Kardashians dominating.
As well as Kim, Kourtney and Khloe Kardashian and Kendall and Kyle Jenner all occupy places in the top seven.
The rest of the line-up is made up by Cara Delevingne and Gigi Hadid.
