Joe played Mickey Miller in EastEnders and is friends with Ben’s sister, Brooke Kinsella, who also starred in the BBC One soap, and her family.
An ITV spokeswoman said the money raised by viewers’ votes was still being calculated. Reports have put the money at £30,000.
The Ben Kinsella fund was set up by the 16-year-old’s family after he was stabbed to death in June in north London.
The fund will provide money for charities and finance anti-street crime campaigns.
Joe told the Sun: “This campaign means a lot to me… I hope any money I may have got from people will be able to make a difference.
“Knife crime is getting out of hand.”
