You can calculate your liquid net worth on your own with a piece of paper and a calculator. List out all the assets you can cash out today, bank accounts, certificates of deposits, savings accounts, and stocks. Then turn to your liabilities, and sum up all you owe. Your liquid total minus the liabilities gives you the liquid net worth. If you want to add the illiquid items, you must subtract 10 to 30%, but ideally 20%, of their value.
