How to Calculate Par Value of Common Stock (3 Steps)

Look through the company's financial statements for the balance sheet. It should have three sections: assets, liabilities and shareholders' equity. Go to the shareholders' equity section of the balance sheet. Sometimes the company uses the term 'stockholders' equity,' which means the same thing.
Identify the line referring to the company's issuance of common stock. It will say something such as 'book value of common shares outstanding' or 'book value of common shares.' This line will also provide the number of shares outstanding and the par value of the common stock, if any.
If the par value is not explicitly stated, divide the book value of the common shares outstanding by the number of common shares outstanding. The result is the par value for one share of that company's common stock.

How to Buy Partial Shares of Stock (3 Steps)

Analyze your investment objectives and risk tolerance before you start researching companies that offer direct investment plans. Once you know the kind of stocks that are appropriate for your portfolio, look for companies that offer a direct stock purchase plan. Contact each company's investor relations department and request a plan prospectus and any other company disclosure statements that are available. Read this information carefully to ensure that you understand the plan's provisions, and select a company to trade with.
Open an account with the selected company's plan administrator. Complete a new account application if required, which will ask for some personal information, such as your name, address, contact information, and Social Security number. Some plans allow you to set up a regular, automatic investment plan that drafts a pre-determined checking or savings account. You'll be able to choose whether you want your dividends to be automatically reinvested into additional company shares or to be paid to you in cash, or whether you want a combination of the two.
Deposit the money for your purchase. When you first set up your account you might have to pay an application fee, set-up fee, or new account fee along with the amount of your initial purchase. Rather than purchasing a fixed number of shares of company stock, you'll be contributing a fixed dollar amount. The plan administrator will pool your money with money from all of the other plan participants and purchase company stock in one transaction. The plan administrator will divide the shares among each of the plan participants on a pro rata basis, which will likely result in both whole and partial shares credited to your account.
