You’re actually right. I must admit I didn’t pay too much attention to Mrs MBs pension I thought the career average was divided by 80 but it’s 54 and I didn’t realise the NHS contributions were that high - I thought it was the total. She’s worth more than I thought ;)
It doesn’t make a lot of sense though as they don’t pay out basis a specific pot value like you and I will have in our private pots it’s a defined benefits one - maybe it’s because they don’t invest it even at draw down like you would do a private scheme. Anyroad it is what it is, so your point stands.
I would assume its to do with investment risk. Stock markets are volatile, yes you can make a lot if you invest in the right funds but you can also lose a lot. The government are more likely to put the funds (assuming there really is a fund !) in the international bond markets or gold, where returns are much lower but the volatility is lower. This in essence is why people refer to them as gold plated by comparison to defined contribution (DC) pensions as there is no risk or uncertainty when it comes to the value when drawing the pension.
To obtain an annuity which pays around 20k (40/60ths of a 30k salary) per year from the age of 67 at todays rates, which have improved due to interest rates being higher, you would need a pot of around £380k. Go back a few years and you were looking to £500k for the same amount. Someone earning 30k wouldn't stand a chance in a DC pension of reaching 380k after 40 plus years working unless they took an exceptionally high risk approach.
In terms of typical employer contribution in the private sector...
Tesco (one of the UKs largest private employers) - match up to 7.5% of salary of employees contributions
Barclays - pay a flat 8% on top assuming employees pay a minimum of 3% capped at 5%
Balfour Beatty (One of the UK's largest construction companies) - match employees up to 5% and pay 2% on top.
The business I work for pay double contributions up to 5% of salary.
As for shares and significant bonuses, unless you are in senior management in most companies, shares are off the table and bonuses are low single digit percentages of salary if the board decide you can have one.
You could say that the private sector should pay more into pensions and they should, but there would need to be more support for small businesses as they would be unable to do it.
Whether people are better off working in the private sector or public sector financially is really dependent on where you end up. Manage to climb the greasy pole to the top table of a private company and the money pours in but if you're just another employee then you'd have been better off in the long run working in the public sector.
