For couples/roommates with different incomes — how do you split shared expenses fairly?
My partner and I earn pretty differently, and lately splitting everything 50/50 has started to feel off — the person earning less feels a much bigger pinch on the same bill.
I've seen some people split proportionally to income instead (if you earn 60% of the combined total, you cover 60% of shared costs). It sounds fairer in theory, but I'm curious how it works in practice for people actually doing it.
For those of you living with a partner or roommate:
Do you split evenly, proportionally, or some other way?
How do you actually track it without it becoming a monthly argument?
Does anyone bother with apps for this, or is it just a shared note / spreadsheet?
Trying to figure out a system that feels fair long-term. Curious what's worked (or blown up) for you.
