It's unknown for us how much the rate up is. However, many months ago I was reading some thread in reddit. There, many whale players where talking about their experiences summoning in rate up, sharing their results, etc. And according to them, the rate up is around 50%.

That means you have 1% to obtain one 5 Servant, and if you obtain one, you have 50% of obtaining the rate-up Servant. Of there are more than one Servant, then you have (100/X)% with each one.

Let's say there is rate up of Artoria Pendragon (Saber) and Mordred (Saber). First you need to succeed in the 1% to get one 5. Then you need to succeed in the 50% to obtain one of the rate-up. Then you have 50% of obtaining Artoria and 50% of obtaininf Mordred.

But, once again, this is just a theory. No one is sure about this.
