young，无房无家庭单身*性，应该放多少401(k)

for first 3-5 years, maximum your 401k as Fed tax limit if your emergence fund is already enough. And you still have some money enjoy your life.
invest them whole into stock section.

later on , just throw some money for the company match

later later on , you need buy a tax shelter

invest for your future before too late.

: 工作第一年就开始放？过了几年再放？还是一点不放？
: 放5%（公司match5%),还是更多？
: 另外放在那种基金最适合？
