How do you know if you're saving enough for retirement?

First determine what you want "retirement" to look like! Then, you get to figure out how much that life will cost (both annually and monthly).

Then, how much income will you bring in? Think rental real estate, pensions, Social Security.

Finally, how much will your savings return? This could be in IRA's, 401k's, 403b's, Superannuation, or mutual funds outside of these accounts.

Note: I'm always looking for at least an average 10% annual return. Example, $500,000 invested well will provide you with $50,000/year.
