WEALTH
Wealth has come to mean an abundance of items of economic value, or the state of controlling or possessing such items, and encompasses money, real estate and personal property. In many countries wealth is also measured by reference to access to essential services such as health care, or the possession of crops and livestock. An individual who is wealthy, affluent, or rich is someone who has accumulated substantial wealth relative to others in their society or reference group. In economics, wealth refers to the value of assets owned minus the value of liabilities owed at a point in time.

Sustainable Wealth
According to the author of Wealth Odyssey, Larry R. Frank Sr, wealth is what sustains you when you are not working. It is net worth, not income, which is important when you retire or are unable to work (premature loss of income due to injury or illness is actually a risk management issue). The key question is how long would a certain wealth last? Ongoing withdrawal research has sustainable withdrawal rates anywhere between approximately 3 percent and 8 percent, depending on the research’s assumptions. Time, how long wealth might last, then becomes a function of how many times does the percentage withdrawal rate go into all the assets. Example: withdrawing 3 percent a year into 100 percent equals 33.3 years; 4 percent equals 25 years; 8 percent equals 12.5 years, etc. This ignores any growth, which presumably would be used to offset the effects of inflation. Growth greater than the withdrawal rate would extend the time assets may last, while negative growth would reduce the time assets may last. Clearly a lower withdrawal rate is more conservative. Knowing this helps you determine how much wealth you need also. Example: you know you will need $40,000 a year and use a 4 percent withdrawal rate, then you need to use 5 percent and therefore need $800,000, etc. This simple “wealth rule” helps you estimate both the time and the amount.(1)
