If I was relying on my pension, then I would not have enough money for everyday expenses, let alone holidays, house maintenance, new car etc. However, I do have access to funds that I saved hard for when I was working - bought ISAs most years, bought Premium bonds, contributed to FAVCS ( like a secondary pension) and other investments. So I supplement my pension by using my investments or drawdown from my supplementary pension ( instead of taking out an annuity) and I feel very secure and am enjoying a good retirement.
Just basing your retirement on pensions is not the full picture for many people like myself, for my last 10 years of work I was earning good money as a Deputy Head in a large comprehensive, mortgage paid off, children financially independent and divorced so only myself to think about.
The fairly recent pension changes to allow draw down instead of having to have a regular income also suits me better, allowing me access to lump sums for expensive purchases instead of having to save up for them.
The value of your house might also be a consideration, especially if you no longer have a mortgage. I own a three bed bungalow in a decent area of Manchester/Cheshire borders and if my savings run out, I plan to sell it and move into a smaller 2 bed apartment releasing a lump sum for me to spend - or pay for care!
So, if I were in my 40s and looking at what my retirement might be like, I’d look at a wider picture than simply having an income from pensions.
I appreciate that I was fortunate to be able to plan ahead but I’ve always been careful with my money, had some tough times with the high interest rates on mortgages in the 1980s when we almost lost our house, and now I can enjoy my retirement.
