For the book The Millionaire Next Door, researchers asked the question, 'Do you know how much your family spends each year for food, clothing and shelter?' Almost two thirds (62.4 percent) of the millionaires said 'yes.' Only about 35% of non-millionaires said they did, even though they are high-income earners.
The millionaires also budgeted very carefully for savings and most save 20% or more of their gross income. Few save less than 15%. 'Why save so much,' you ask? Quite simply, for emergencies, opportunities and to provide future income.
