If you want to receive Rs 6000 a month as a pension when you retire, this is probably not enough money for a comfortable retirement if you have just started earning. However, if you are 25 and want to start saving Rs 6000 a month towards your retirement, this could be a good amount to start with. But imagine getting Rs.6000 every month to live your life after 20-25 years, when the cost of goods would have increased due to inflation. The amount may not be sufficient to take care of your post-retirement expenses.
