@Monwmum you said: "However, public sector pensions are still getting contributions of the high 20% figures while private sector pensions range from 4% -10%."
I posted this on another thread last week, but I think it bears repeating as so many people don't understand how public sector pensions work (including lots of PS workers, and myself until quite recently!)
You cannot compare the high 20% employee contributions in the public sector to the 3-10% contributions in the private sector as they are going towards different things. Private sector contributions go directly into your pension 'pot' which is invested in the stock market. Individuals in public sector schemes don't have a pension pot.
The civil service contribution of 27% is going into the overall running of the entire scheme. It has no bearing on what the retiree ends up getting because they receive a career average (not final salary) based on set rates when they retire.
For example, on the 'Alpha' scheme, which all new civil servants join, you will have somewhere between 4.5-7.5% of your monthly salary taken out as a pension contribution. This contribution is used to purchase 2.32% of your salary every year and this accrues until you take your pension.
Let's say you earn £24k (£2k per month) and your contribution rate is 5% – that 5% (£100) buys you £46.40 (2.32% of your £2k salary) for your pension, or £556.80 over a year. If you work there for 20 years (assuming no pay rises/inflation for simplicity) you will have built up an annual pension of £11,136 (£556.80 x 20) which is paid out of the money built up by the employer contributions (27% in the civil service).
It is quite confusing as the media (Telegraph, I'm looking at you) conflate the public sector employer contribution and private sector contributions all the time - But they are chalk and cheese.
However, it is true to say the accrual rate is good and public sector pensions overall are good. They should be too, because the majority of public sector works earn well below what they could earn in the private sector, and the pension is recompense for that.
