2% per year of service, calculated based on the average of the best 5 consecutive years of service, up to a maximum of 35 years. The federal servant pension scheme is contributory, that is, employees contribute half and the government the other half unlike the private industry which is usually non-contributory. The contribution is close to 7% of your salary.
The selling point is:
1. Because it is a defined benefit scheme, that is, the pension payout is only dependent on your salary only and not controlled by how the stock market and/or the company is doing, it is very secure.
2. It is also indexed, i.e. it increases based on living standard increase calculated by some magic formula.
I know, because I am a retired civil servant.
