I don't know if this will help but what I do it get a plain sheet of paper - doc format (or use excel if your comfortable with it) use household income as your total, subtract what I call the 'non-negotiables' (bills) - Mortgage, loans, Electricity, Petrol & diesel (gas), heating, phone = subtotal 1
Then (usually at the very start of the year but doesn't have to be) I calculate what I call yearly expenses. These are one off payments that come up every year such as - health & eye checks, house insurance, car tax, car insurance, car service, holidays, Christmas, expenses, birthdays etc. This sum I divide by 12 and have deducted every month to go into a seperate account so it is there to meet the expenses as they come up - so we have no "surprises". That leaves sub-total 2. Out of this them comes, groceries, lunches etc during the month, savings, clothes,what we call fun money for socialising etc and discretionary spending.
When it comes groceries, I meal plan per half-month / fortnight and I make a list, so we only buy what's needed, I know approximately the cost of each item as its listed also. I find this cuts down on expense and cuts down on waste as well.
In case you haven't guessed - I do the budgetting and cooking in our house

This probably sounds quite boring and old-fashioned but because my beloved is not very disciplined whren it comes to money management, it works for us.
