What is considered income?

Twice your current income

Another Answer:

Wealth is not directly related to income. The usual measure of wealth is "Net Worth", which is the total value of an individual's assets (not including a primary residence and not including cars) minus any debts (mortgage, car loans, credit cards).

For many people, the threshold of being "wealthy" means having sufficient assets to maintain their lifestyle without being employed by someone else--in other Words, to be able to retire, regardless of age. The usual rule of thumb is that you need to have accumulated a net worth that is 20 times the net income that you need. Or, to look at it another way, you need to be able to live on a 5% return on your assets.

There are many people who have high incomes, but have not accumulated very much wealth. They are at a disadvantage because they are accustomed to a lifestyle that will not permit them to accumulate wealth at a sufficient rate. Conversely, there are many people who have modest incomes but have accumulated enough assets to be financially independent.
