How to share income after marriage and kids?
My own personal point of view. I earn about twice what my wife to be earns. We are planning on getting married next year.  I ultimately do all the finances (basically because she hates that kind of thing) not because I'm in charge or whatever. To work out how we do this I wrote a spreadsheet:  At the top it has my monthly pay in one column and her's in another. I add all our bills (against me initally). At the bottom I have a total of both of our "spending money". Spending money is wage - bills - savings I then move money out of my column into her column. My goal is that we pay all the bills and save a decent amount and have roughly the same amount to spend each month. So each persons spending money should be roughly equal. I then fine tune this as things change (if we get a pay rise we alter it, if a bill goes up or down we alter it) To manage this we have 4 accounts, a joint account to pay bills (both give a set amount to each mont), a savings acount (both give a set amount to each month) and our own accounts (where we get paid and where our spending money lives). Like everyone else says, this seems fair to me. I don't earn more, we both earn "an amount" and this should be split equally.
