The return on assets calculator is created to help you determine if you are wisely using the assets that are controlled by your business. The calculation is made in several steps.

The first step is to determine your average inventory for the past year. Enter in the ending inventory for each of the past 12 months.

The second step is to total your operating expenses for a 12 month period. Do that in the "Annual Operating Expenses" section.

The third section is where you input the amount of assets at year end. After that you input your cash sales and charge sales. Charge sales are not bank card sales, but are from 'house' or corporate charge accounts.

The input of 'cost of goods sold' should be from a year end profit and loss statement. Miscellaneous business income is often for income from investments, dividends from buying groups, or rent collected for space that is provided to other businesses.
