basically anything that isn't essential such as going to the cinema going to restaurants etc
at the moment for me 0% mainly just the essentials for me
I don't go out drinking have not done so for many years, apart from having a drink with a meal, which I aim to do at least once per week. I enjoy a single glass of wine with a meal at home, so I make my own wine every few months, 30L at a time. I've not visited the cinema for 30 years and only then, to take kids. I do enjoy watching a good film, but good films come along rarely and the TV serves more than adequately for those.
I have never felt the need for 'retail therapy', I am quite happy buying from the charity shops - not because I need to, just because it helps the charities and I don't like to see waste. I carefully avoid any clothes with makers names emblazoned on them on principle - I expect to be paid to advertise for them.
I've never been one generally for just deciding to buy something on the spot, rather I will usually do the research and look for the best price. Often I will decide to drop the idea, or talk myself out of it, before getting to the committing to purchase stage.
I keep a car and a tourer caravan, which I cannot strictly classify as being essential, as I have a bus pass and an extremely good service quite close to home.
I eat/heat well, and so far have made no concessions towards economising. I did spend a bit a few years ago, towards reducing my energy consumption, without reducing comfort, by way of investment. I would like to add solar, but cannot justify it on cost / payback time grounds.
I think debt and interest can be one of the worst possible problems, something I have been wary of all of my life and paying interest can cause a life misery. All that is needed is to be a few pounds ahead of your spending, by waiting and delaying spend.
Everyone's ideas of what they class as essential, will vary and even then it varies as time goes on. No one 20 years ago would have described broadband as an essential, but no it is almost and essential service.
