The problem with basing the pensionable future on a couple is that you migh have split before becoming pensioners.
And at some point one if you is going to die
We really need to be able to be able to afford retirement as a single person & that is very hard.
I would love a CS job but I do wonder how much longer the pensions will be as good as they are.
This is sadly the most important thing to bear in mind as I have only recently fully grasped.
My H is 66 and has just been diagnosed with a terminal illness. I am 64 and will get the full New State Pension at 66, plus slightly less than £500 per year private pension, so a total (after April's rise) of around £10,000 a year.
If my H dies before I am 66 I will get half his Defined Benefit Pension, which will be approximately £5,500 a year. That is clearly not enough to live on so I will probably have to get a job at a time when I will be seriously grieving and have lots of other practical things to think about too.
If he lives until I am at least 66, so approx another 16 months, I will have an annual income of 10 + 5,500k, which will be taxed, and so the nett amount will be just under £15k. Which I will have to manage on.
I had thought we'd planned our retirement really quite well, with an annual income of around £30k (including 2 full state pensions and good annual increase of 5% to the private pension part) which would have been comfortable for us as a couple. Yet on my own, with household costs (very high council tax and fuel bills) I think I will have to live quite a frugal life with just £1,200 ish per month for everything. And I will have to pay for stuff to be done that my H used to do without thinking - mending things etc, and some gardening if I can't manage it all.
I had thought I might have to manage alone one day in my old age, but in my mind that wasn't until my late 70's / eighties, when my spending would likely be a lot less. Not thinking for a minute I would be in my mid 60s and still feel young and have to get on with life on my own.
So yes, even if you are thinking of your retirement income as a couple, always keep in mind it might be just you in the years ahead. Hope for the best, prepare for the worst is the best plan.
