31k sounds an awful lot.......
That would require a private pension of approx 300k to give a pension of 20k, with the state at 11k.
People as they age tend to do less, eat less, shop less.
But of course the pensions industry a: wants us to pay in more and b; delay taking our pensions, thats how they make more money after all.
Well, I'm in my 60s, still working for myself and taking an occupational pension. It's not true for everyone that you spend less. With more time, I want to travel and enjoy hobbies, not make my world smaller and stay at home.
Which is why everyone needs to work out their 'number' - if you were on modest income before and are happy to stay home and knit (although craft stuff is expensive now) and not help your kids and grandkids financially, you will manage on less. If you want to go out more, maintain your home, run a car etc, then you need more money.
There's no simple answer, everyone is different. My advice to younger people (especially women) is to think about this as early as you can as the effects of compounding make a huge difference.
