A complete personal financial statement will list an individuals assets, liabilities and net worth. Net worth being the balance left after subtracting the liabilities from the assets.
You may also look at it as a personal "Balance Sheet"
A good statement will break down the asset and liability classes:
Assets:
Cash in Banks (list the accounts separately and the specific bank names)
Real Estate Owned: As a minimum list the address, market value, mortgage balance, mortgage payment, and equity on each property.
Stocks and Investment Accounts: Fund name, amount of shares, current share value, and total balance.
Autos: List year, brand and values.
Other: any other assets, business, gold, boats, personal property, life insurance surrender value.
Liabilities:
Mortgage on property
Credit Card debt
Loans on autos, boats, on life policy, against stock or IRA account. etc.
List all debt.
Net Worth:
It is a single line item with a dollar value.
Subtract the liability total from the asset total and that is the number going into the "Net Worth" line.
