Entropy And Black Holes

According to some theories the area of a black holes event horizon and the entropy put into the hole, combines to an equation somewhat like this:
dA + dS >= 0
Meaning that the total entropy of the universe added with the area of the event horizon (with some factor) will always increase.
If this is correct, and the mass of the black hole determines the area of the event horizon, then there should be some kind of proportionality between the mass dropped into the black hole and the entropy dropped into the black hole.
