Yes, to have your ultimate absorb 100/125/150 damage, you and your allies within it will have to take at least 500/625/750 non-tower damage from when you casted, since the ultimate would absorb 20% of that, equal to the amount of absorbed damage needed to get maximum damage from the ultimate.

That should also work against jungle monsters if such a desperate situation ever happens to you.
