How do you work out the size of your nest egg?
Do the math based upon a 4% return after inflation and taxes. If you move to the right places or get a good accountant, taxes can be eliminated or reduced considerably.
For every $1,000,000 in productive assets, you should receive an income of $40.000 per annum so if you think you need $200,000 per year to support the lifestyle that you wish to enjoy, you need $5,000,000 in assets excluding the family home.
The family home does not count. It yields nothing. It is an overhead as long as you live in it.
If you want the lifestyle of the rich and famous, you'll probably need about $30 million or more. You then enter the realm of private yachts, chartered jets and fancy penthouses.
Less than $20 million and you're very comfortably well off but not really rich.
Remember that this thread is about achieving financial independence and not about becoming super wealthy. I emphasise this because I believe that just about anybody can achieve a target of $4 to 5 million. All it takes is willpower and perseverance. Becoming a billionaire is a different ball game altogether.
