What a strange list!!! Whoever compiled this? Nothing allowed for gas, leccie, insurances, phone line, etc.
Why is it only those living as a couple has allowance for hair colouring? Obviously, singletons do not need this.
The food amount is very high for singles -assume this also includes toiletries, cleaning materials, etc.
Surely, the wine and cans of beer should be part of the weekly 'food' bill.
No allowance made for on-going repair/replacement costs on any household items or clothes/shoes.
Do wonder at the algorythms........!!!
