Seems I'm in the minority, but just to give a different perspective.
We have separate finances. Married with 2 kids. Both employed full time and both juggle the usual childcare and household responsibilities.
Our salaries go into our own personal bank accounts. We then transfer a set amount each month into a joint account to cover joint bills like mortgage, utilities, kids clubs, groceries etc.
Everything else is individual money. So our own clothes, shoes, cars, phone, Indurance, gym & golf membership etc.
I earn more that DH. It I'm also a saver, so we now have a very decent savings pot for rainy day / emergencies. Plus we use my savings for big purchases like replacement freezer, new oven, most holidays etc. So really 'my' savings are family money.
Works for us.
If we only had joint accounts I think it'd burn a hole in my DH pocket! He's not good with money.
