Rule of thumb, if you are single, and still want to live a decent good life, you could easily save half of your after tax salary. eg. if you make 110k a year, after taxes, 401k, health, etc... you are probably bringing about 60-k65k home. You should be easily saving about 30k a year. If you are in expensive areas like SF, live with roomates, and adjust to it. If you are an engineer making about 130k a year, you can upgrade to your own one bedroom and still be able to save about 35k -40k a year. If you are frugal and really good with money, add 10k to those estimates.
