I cannot seem to create a budget that actually works. There are always things I haven't thought of, or it's just unrealistic - would so welcome any advice or help as we're currently going overdrawn at the end of every month, which is obviously not ideal.
Basically, after mortgage and all bills are paid each month, we have almost exactly £600 left. We need to put fuel in two cars (one used for commuting, one only used occasionally), which I think swallows at least £120 per month. We need to feed and clothe DP, DS(1) and I, buy toiletries, cleaning products etc, and occasionally have fun.
In my head this should be more than possible, but I am spectacularly bad at it. We already shop mostly in Lidl but occasionally nip into other places for top-ups/ stuff we can't get. Try to make that mostly Tesco but it's sometimes Sainsburies. We just seem always to spend more than I expect, and random things always come up - family birthdays/ invitations we have to take a bottle of wine to, stuff like that. If you budget successfully, how do you do it?!
