A raised garden bed

A raised garden bed

Okay I am making a raised garden bed on a slight hill. I will need to flatten the area out and I figured I could just used fill dirt. But I was also wondering about the typical ratio of fill dirt to top soil for my raised bed. It's going to be 20" tall so I know it would be costly to do all top soil but I of course want to ensure fertile soil. Any suggestions? Thanks!
