The formula that you would use for calculating net worth would look something like this Assets – Liabilities = Net Worth. You would start by totaling up all your assets both liquid and fixed. Liquid assets are cash or anything that can easily be turned into cash, whereas fixed assets are things that would take a little longer to get the cash out of, for example if you were trying to sell your home. You would total all your assets together and then deduct the total of your liabilities which are any debts that you owe. This will then give you your net worth.
