Retirement savings

My view.
It seems that the average amount that most people need for retirement in the USA is $1 million. I suppose that this include the value of the house. A similar amount will be needed in Singapore, i.e. $500,000 as value of house and $500,000 cash for retirement. At 4% yield (hopefully), $500,000 will produce $20,000 a year or $1,600 a month. This is similar to what most people comments in an earlier article in my blog.

However, if I am mistaken and most people expect $1 million cash on top of a fully paid house, then they are looking at monthly expenses of $3,200.
