I take $400 a week cash out, $50 for DD2s day in care, $50 each for DH and I (lunches/coffees/clothes/personal) and $250 for food and all other 'shops' spending. Petrol and bills go on the CC which is paid in full every month. That leaves us a bit of a buffer in the bank for things like last month when the washing machine dies, i could buy another one straight away (Phew!)
