I'm not the guy you're responding to, but I have the same experience. If anything, 1/4 cost underestimates the savings.
The analogy is like pointing out that you can have a robot vacuum clean your floors every day. Before the robot, you'd do it maybe once a week, just no time - "too expensive" to even think about doing it daily. The robot makes it happen all the time for a tiny, tiny fraction of the cost.
