you just need to do the maths right and double triple check it
i'm 55 and just taking my NHS pension early ( when I started normal retirement age was 60 so I'm taking it 5 years early so there is a reduction for taking it 5 years early), my Dh will be state pension age in 4 years ( roughly 10K as untaxed) mine is 12 years away ( roughly 8K as mine will be taxed) so we have 4 years when our income will be 18K less than max, and 8 years when it will be 8k less than max. I will also get a lump sum equivalent to 3 years pension
However we do not need the max to live on, we have paid our mortgage off a couple of years ago, my NHS pension will pay for us to live covering all reasonable annual costs, what myself and DH earn in next few years as P/T and self employed will pay for all the extras holidays , newish car in 3-4 years from now. we are generally fairly frugal in that we don't spend a lot on clothes or entertainment or TV packages but we do spend on decent food and we like to travel a bit but not long haul or 5 star hotels, more exploring little unknown areas from a nice apartment or B and B , we like history, antiques and gardening i'm involved at church. my calculations for holidays etc mean we need to earn around 6-8 k after tax for the next 4 years then nothing more.
The lump sum will help with DD at Uni, we live in Scotland so no tuition
we have other savings and once DD is at uni we will downsize probably not a lot of equity as may move to more expensive sunnnier area
you need to do your sums check your pension is index linked etc and that you can afford not just day to day expenses but also central heating breaking
also as you get older you probably find you need to pay more people to do simple DIY and maintenace or gardening that you used to do yourself, but by that stage you maybe spending less on travel etc
for many people living with less money more simply and content with simple pleasures is a trade off against working more for more money and it depends on you and your circumstances whether it is possible
the best advice to young people is never ever opt out of a pension unless you are in danger of starving, and always live below your means and save if you can especially in the good years saving when your kids are between 0-5 years is very hard. buy the biggest house you need not the biggest house you can get with the maximum the bank will lend you, if the house you need and like costs 400K don't buy a 600k house just because they bank will lend 600K
lifestyle inflation is the enemy of savings
