The skipper made the charitable gesture on Monday night and said that it was "the least" that he could do to help the campaign.
"It was something I wanted to do behind the scenes because I've got my own connection [to Hillsborough] through my own family," Gerrard told BT Sport.
"The people in this city have always supported me and it was the least I could do. Of course [Everton fans have been supportive]. When there's a tragedy in this city, there's a big togetherness.
"I want to say a big 'thank you' to all the Everton fans who have supported this campaign."
