FYI: The butter in my fridge has 743kcal per 100g.

Could you share how much butter you bought per month and what the package size was?

I'd estimate that my family of four was going through a pound of butter a week. As I mentioned above, I doubt that butter alone was the cause, since the butter was always accompanied by something else.

My whole family has reduced our butter intake quite drastically, so I don't have a good estimate of how much I was personally consuming.
