No, you won't. Why would they give you back your initial investment? What's the point of them existing then?
You will just get the profit from mining with that speed minus whatever fees they list (management and electricity fee are usually in play).
Anyway, you will probably not earn much or even earn at all from cloud mining. It's widely known that you should avoid using any cloud mining.
But if that is your only option, that someone will more experience will chime in, as I tested cloud mining for 3 months or so before I got into real mining, and never looked back.
