1 separate current account each, which our individual paychecks go into, and 1 shared joint account, which all household expenses, bills, mortgage etc. comes out of.
We both put the same percentage of our individual monthly income into the joint account each month to cover the bills. As we're not paid the same though, this means one of us covers more of the bills than the other.
We have a fixed direct debit set up to transfer this into the joint account at the end of each month.
For non-regular big purchases, holidays etc. we usually split costs the same way, based on the ratio of our incomes. Simple but fair!
Same here - optimizing for equal purchasing power definitely makes things simple. Do we want to order pizza for the third time in a week? Well, it will hurt our financials equally.
