Does the added component (intended to disturb equilibrium) always ends up being more than the original amount, in the new equilibrium?

The title can be a little unclear. But what I am basically saying is say we add a reactant to a reaction to push the reaction forward toward the product side, that reactant which was increased in amount/ concentration will surely less. Part of it used to produce more products to gain new equilibrium. **But will it always be more than the original amount in the equilibrium before?**


Without knowing much of advanced math, I just experimented with some simple fractions; thus far I haven't seen anything that violate this rule.
