For those in relationships, how do you guys split the finances? I read many of those his money is hers and hers is hers type replies regarding money but how does it relate to real life?

Its seems unfair if the net income is 6k a month (him 4, her 2) and costs per month are 4k to have him pay 100%, keep nothing while she keeps her 2k...

We do a split based on income. I work fullltime, she works parttime, split is 60/40 while she does more in the household than me.

We have a shared bank account for all costs including groceries and gas. Both have seperate accounts for personal stuff alongside a shared savings account.

Works better than 1shared account imo since there is less questions about who spend what.

I wonder whats common in other situations?
