It really depends on your circumstances, stage of life and priorities. Also what you count as 'savings'.
Some people count every penny they don't spend in a particular month as 'savings'. Others account for every last irregular/unexpected expense such as holidays, Christmas, insurance, broken cars, pets and washing machines etc etc before they regard money as truely disposable.
Some people's basic costs (the percentage of their income they spend on housing, food and bills) are a large part of their income, either by necessity or choice and they have little left for outings, activities and other general things so the percentage is small.
Some people have debts that they need to be repaying, some want to overpay their mortgage, some want to save for a mortgage deposit so need to prioritise that and likely spend less on other things.
Others might have plenty of disposable income but spend a lot of it on day to day non essentials so as well as your outings and activities, lots of food and drink out of the house, and clothes, accessories and grooming etc, so they still save little.
Etc etc.
You need to review your incomings and outgoings and arrange them in the way that fits best for you.

Even the amount of disposable income saved varies - some people live for today and spend all their money, others save most or all of their disposable. Both ways can have their downsides.
Obviously it's not great to spend all your money on fun stuff and then not be able to afford to replace the washing machine when it breaks in 6 months time, but equally there's no point working and living like a monk then dying as a millionaire. Somewhere in the middle would be what to aim for.
People will cope in different ways with increasing costs depending on where they were before and where they are now. Has their disposable income been wiped out, or just reduced. Or have they managed to mitigate the impact by increasing their income?
