That’s a staggering sum, especially in an era of stagnating wages, rocketing prices and volatile stock markets.
The Pension and Lifetime Savings Association (PLSA) calculates that roughly speaking, a single person needs total pension income £12,800 a year after tax to achieve the “minimum” living standard.
This rises to £23,300 a year for a “moderate” lifestyle, and £37,300 a year to be “comfortable”.
Inevitably, couples need more money: £19,900 a year as a bare minimum, £34,000 for a moderate living standard and £54,500 to enjoy a bit of comfort.
Many pensioners will look at those figures and wonder how anyone can generate that much, as millions scrape by on much less.
For pensioners who only get the state pension, even the minimum will be out of reach.
The new state pension pays £10,600 a year, but only to those who have made the maximum 35 years of National Insurance contributions.
Those who retired before April 6, 2016 on the basic state pension will get £8,122 a year at most.
While many will get that topped up by additional state pension such as Serps and S2P, others get even less and should apply for means-tested benefit Pension Credit.
It’s clear that we all have to build wealth in our own names to have any hope of enjoying retirement.
Most pension projections assume retirees pensioners have paid off their mortgage but this needs to change as younger generations struggle to get on the housing ladder, Webb said.
Most of the talk around “generation rent” has focused on people in their 20s and 30s who are fighting to get on the property ladder, but plenty of older people are stuck renting, too.
As generation rent gets older its problems will only intensify.
Saving for retirement can look like mission impossible, but there is one positive.
Typically, Tom Cruise only has a day or two to save the world, while workers have 40 years or more to build their pension.
Given the scale of the challenge, they can’t afford to waste a single day of it.
Some people have shown it’s possible, like this flight attendant, who saved £521,000 and was able to retire early. But it’s not easy.
