Assets found on left hand side of an accounting balance sheet represent the investment decisions of a firm’s managers. This side includes cash, machinery, land, plant, equipment and anything else of value owned by the company. The right hand side of the balance sheet includes both liabilities and owner’s equity. Liabilities are anything that the company owes such as long-term debt, short-term debt, notes, and unearned revenue.
Included on the right side of the balance sheet is the owner’s equity or a calculation of what the company is worth. This value also represents the value to the company’s owners, typically the stockholders of a corporation. These two sides of a balance sheet give rise to the balance sheet identity. As its name implies, everything on the left side of balance sheet must equal everything on the right side. The balance sheet identity is given as:
Assets = Liabilities + Owner’s Equity
At first glance, the balance sheet identity does not make intuitive sense. However, doing some simple algebra, we can rearrange the identity to look like this:
Owner’s Equity = Assets – Liabilities
Now the identity makes more sense. It states that what a company is worth (owner’s equity) is its assets minus its liabilities; the company’s worth is determined by removing from its assets what it owes in debt. This basic identity is the foundation for calculating personal net worth.
