Retiree wealth has jumped over the last 40 years, and disposable income is now at a record high of £22,000 on average, according to the Office for National Statistics (ONS).
But many pensioners have disposable income that is thousands of pounds higher than working households.
The richest retirees are likely to fall into three distinct categories, and those who fall into all are typically the best off, shows analysis by pension provider Aviva.
Britons who are men, born in 1950 and married have typically hit the retirement jackpot.
People born in the 1950s have benefitted from the generous final salary employer pensions, which were at their height in the 1970s to early 1990s.
Since then the schemes have largely been phased out and replaced by defined contribution schemes.
Private employers give around six times more into final salary pensions, according to Aviva.
Britons born in 1950 have also benefited from the state pension triple lock – increasing the value of the state pension by at least 2.5 per cent each a year since 2010.
At the same time, male and married pensioners have enjoyed more income in retirement than those who are women or single, analysis has consistently showed.
Men were the most likely to be members of final salary pensions.
For example, in 1975, 58 per cent of men in private sector employment were in occupational schemes, but only 17 per cent of women.
Men born in 1950 have also avoided the impact of the planned increases in the state pension age.
Alistair McQueen, head of savings and retirement at Aviva said: “Few, on average, are likely to enjoy a greater retirement income than a married man born in 1950.
“He is, on average, a member of a fortunate generation that has benefited from generous workplace pensions; been rewarded by the state pension triple lock; and has avoided planned increases in the state pension age.
“The new challenge is to support those not enjoying this relative good fortune – especially the young.
“The young are far less likely to enjoy the same generous defined benefit occupational pensions.
“Instead, automatic enrolment into defined contributions is to be the vehicle that carries them to their retirement.
“Our responsibility is to celebrate all those who begin saving today, but also to educate them on how their retirement may differ from that enjoyed by their parents or grandparents if we stick to minimum levels of saving.”
