Equity is the amount of capital invested or owned by the owner of a company. The equity is evaluated by the difference between liabilities and assets recorded on the balance sheet of a company. The worthiness of equity is based on the present share price or a value regulated by the valuation professionals or investors. This account is also known as owners or stockholders or shareholders equity.
Equity Formula:
The accounting equation is Assets – Liabilities = Equity
A bond is a debt security, similar to an IOU. Borrowers issue bonds to raise money from investors willing to lend them money for a certain amount of time.
When you buy a bond, you are lending to the issuer, which may be a government, municipality, or corporation. In return, the issuer promises to pay you a specified rate of interest during the life of the bond and to repay the principal, also known as face value or par value of the bond, when it "matures," or comes due after a set period of time.
