Changing the iTunes account on my iPhone?

So, I have decided that I want my own iTunes account separate from the rest of my family's. I know that when i change the account on my iphone, songs and apps will be lost, but i have figured out a way to keep them. So my question is that when i change the account on my phone, will my contacts be deleted? If it helps, i haven't set up icloud yet.thanks.

Added (1). @Valerie, that wasn't my question…

Go to settings, then store, then apple id, sign out, then go to apple id again, and select create a new apple id
