My girlfriend and I are planning to move in together in ~3 months.
I own a small apartment in Amsterdam, my mortgage, heating, water and electricity is about 2000 Euro a month, and I earn 30% more than she does.
Some context: Amsterdam is damn expensive and in an housing crisis, since living here she’s been paying about 1000/m to rent a room. Both of us earn quite well and money isn’t tight
What is a fair way to split costs? I’ve heard everything from she should live here for free because I was paying for everything anyway to we should split everything 50/50, and I’m not sure what is fair.
I don’t think 50/50 is fair, because the way I see it, I’m going to get back a fair amount of the money I pay to my mortgage when I sell the apartment.
So what is fair? My gut feeling is something like we split the heating, electricity, groceries etc. 50/50. And she pays say 500 Euro a month for living here (less than half what she’s used to paying in rent)
Like others have said, one option is to have a chat with her.
Another option could be coming up with a percentage that fits your 30% increase in earnings:
Assuming you start with a 50/50 split, we can add a 30% increase to your share:
0.5 * (1 + 0.3) = 0.65This 30% increase leads to a 65/35 ratio, where you would be paying 65%, and she 35%.
Math is off.
He makes 30% more than her. If she makes 100, he makes 130. The total income is 230.
Her income is 43% of that (100/230) and his is 57% (130/230).
