2017 Add-on: The "last time" mentioned above was 1999. Now, 18 years later, my wife and I are living in a condo in South Florida, surviving totally on Social Security and my website business/hobby. Only possible, I think, becuase wer were able to pay off house, cars, etc. Only bills now are every day living expenses, condo fees, taxes, and ... of course ... the occasional "unexpected emergency." Not saying my retirement advice is necessarily correct for all, but it worked pretty well for us.

The amount it takes to retire depends upon one factor only -- how expensively you plan to live. I wrote a book a few years ago entitled "Retire and Travel for $1000 a Month" -- Click here to go read it online. My wife claims she could write a rebuttal demonstrating how no sane person would try it for $1000 per month. I explain in the book, however, what this entails. I provide a budget, showing the actual expenses when we tried this for about 5 months. If you read it and decide you can't live with the restrictions, then $1000 a month isn't enough for you. Also, I forgot about a couple of things which may be significant for you, as explained on the More on RV Travel page. I also included many updated ideas in the sequel "Retire and Travel - 20 Years Later." Click here to read about it and/or purchase a copy. Finally, you can see the opinions and experience of website viewers summarized in my Retirement Survey.

When I did a search (in Yahoo!) on "retire", I got 550,000 webpage hits. I obviously can't say that I perused them all, but I've spent many hours wandering through many of them. One thing I've found is that there are many people out there who have spent much more time than I on the question of how much it takes to retire. I've done spreadsheets that assume a reasonable rate of return on your IRA and a specific monthly allowance, but some of the sites I found have complete programs dedicated to the questions. Take a look at some of the following and pick the one you like best -- they each have their own ideas on how to "size your stake".

HOW MUCH DO I NEED?
First, you get my opinion. What are my credentials? Well, I've retired four times, going back to work each time except the last one. This could either be viewed as "experienced, therefore can give advice" or "hasn't gotten it right in 3 tries, therefore shouldn't give advice". I'll go with the former and give some advice. You, of course, can ignore it or follow it, as you wish. Also, I wasn't real serious about staying out until this last time.
