Net worth is arrived at by taking all of your assets (everything that you own) and subtracting your liabilities (everything that you owe). The infographic shows the U.S. median household net worth based on a report issued by the U.S. Census Bureau in 2011.
Ultimately, your savings goal and amount of net worth you want to have by age 65 will depend on how you would like to spend your retirement years based on many considerations including, but not limited to, your health, the amount of traveling you will be doing, your level of activity and other income streams (social security, earnings from investments, etc.)
