DH and I, teen DD and a dog.
I budget €1,200 per month (€300 per week) and over the course of the year, that has worked out just about right for what I spend. But DD has brought DH out fairly frequently as well which is not included.
There's an element of treating ourselves as the world fell to chaos, and also convenience as despite WFH DH and I are flat out. DD has also become very very fussy about food (ASD issues around textures etc, and also very sporty so burns off a lot, and mid-teen girl fads all rolled into one), and seems to be a bottomless pit on some things but throws out lots that has gone off before she eats (and yes, it is HER food that she has put in the trolley so DH and I don't go at it). And there has been significant food price increases to deal with as well.
There's also having my stores somewhat higher than normal due to Covid, the difficulties with shopping and the potential we may need to isolate. And a number of delivery fees for various grocery related items - between online groceries from the local SM to postage fees for the lovely hot choc mix we can't get in the farmer's market just now but they will post etc. And buying from local artisan butchers and the good local deli etc as small treats.
But it covers everything I spend in the supermarket, butcher, fish monger, off licence etc, any hair and beauty items from Boots etc (although not meds), cleaning products, coffee pods etc.
And there are some months that are much lower as I have veg from the garden and use up what's in the house - but other months that are well over as I go to various bulk stores or specialist stores to restock...so a monthly budget that I keep a track of the annual cost works well for me.
In early 2019, I had increased from €750 to €800 per month, I saw that needed to go up in early 2020 to €1,000 per month, but bowed to the inevitable in Feb 2020 and increased to €1,200 at that stage. We can afford it, but I want to tackle it a bit now as we get back to a semblance of normality, so my aim is to bring it back down again this winter and get ourselves back into good habits around batch cooking and bulk freezing, and spending less on takeaways and conveniences as well.
