The family (My wife, daughter and I) are considering a vacation. We would split a house near a beach with my sister-in-law (single) and a friend who is a single mom, bringing three kids. But, interesting enough, I am at a bit of a loss as to how to split the bill. Assuming the house is $4000 to keep the math easy, these are the choices:
So, the first line shows that if simply count people, it’s $500 per person and this is the split. But if we count bedrooms (there are 5), the sister-in-law uses one, we use 1-1/2 as our daughter would share a room with the friend’s daughter, and the friend uses 2-1/2, one for her, one for the two boys she has and one half split with her daughter and ours. In this choice we pay $300 less at the expense of my sister-in-law. The third proposal, that we each pay one third just seems crazy, why should my sister-in-law pay the same as the friend bringing three kids or the three of us? Last choice, the 40/40/20 split. This costs us the most, but seemed fair in comparison to the other choices.
I know this isn’t rocket science, how would you split the bill? Any other way I’ve missed?
