Interest Earned

What is Interest Earned?

Interest is a fee charged by a lender to a borrower for lending money. For a business, interest earned usually arises on money deposited with a financial institution such as a bank, and can be simple or compound interest.

Interest earned is usually reported in the financial statements of a business in the accounting period in which it is earned under the accounting categories of interest income, interest revenue, or investment revenue.

The amount of interest earned depends on the amount invested, the interest rate, and the length of time over which it is invested.

For example, if a business has deposited 10,000 with a bank earning 5% simple interest, at the end of the year, the interest earned is 10,000 x 5% = 500. If the interest is deposited in the bank account of the business, the accounting journal to post this interest earned to the accounting records would be as follows.

Cash 500
Interest income 500
Total 500 500

The Accounting Equation

The Accounting Equation, Assets = Liabilities + Owners Equity means that the total assets of the business are always equal to the total liabilities plus the equity of the business. This is true at any time and applies to each transaction. For this transaction the Accounting equation is shown in the following table.

In this case one asset (cash) increases representing money received in respect of interest earned, this increase is balanced by the increase in owners equity. The credit to the income statement for the interest income increases the net income which increases the retained earnings and therefore the owners equity in the business.
