Find a product you can promote using paid traffic, which yields you enough margins.

Assuming that you get paid monthly, that there are no caps on the product, and that you get the same margins consistently:

A product with 100% margin will have you grossing $1 million in four months.

A product with 50% margin will have you grossing $1 million in six months.

A product with 25% margin will have you grossing $1 million in eleven months.

A product with 20% margin will have you grossing $1 million in fourteen months.

Even a product with a mere 10% margin will have you grossing $1 million in a little over two years.

Assuming you can sell the whole of your inventory in 1 month, re-invest all income and do the same for the next month?

Also assuming the margins are after all expenses? Isn't Amazon FBA taking like 30% cut?
