Calum Thomas Hood was born on 25 January 1996 and raised in Mount Druitt, New South Wales. His father, David Hood, is a former Coca-Cola employee, while his mother, Joy Hood, worked in the superannuation industry. Through his father he claims Scottish descent, and through his mother he claims Māori descent. Hood is the younger brother of singer-songwriter, Mali-Koa. Hood recalls his childhood upbringing to be "middle-class" and "not the most glamorous life". Hood attended Norwest Primary School where he befriended future band-mate Michael Clifford in the third grade. For his high-school education, Hood attended Norwest Christian College where he befriended future band-mate Luke Hemmings in Year 7 after they performed a Secondhand Serenade cover at a school talent show.
Throughout his childhood and early teenage years, Hood took a keen interest in sports, particularly football (soccer), which he had a "promising future" in and visited a Brazil training camp for, in order to pursue the sport as a career. However, after the formation of the band and due to the band's move to London in late 2012, he ultimately decided to stop playing football to instead pursue music. Hood later recalled that after quitting football, "there was a period of a month where my parents thought I was making the worst decision of my life. My mum threw out all the clothes in my closet. And I left [...] just being like, I made one of the biggest decisions. But now it's worked out". Following his decision to quit playing football, he dropped out of high-school in 2012 after completing Year 11.
