The return on assets ratio formula is calculated by dividing net income by average total assets.

Average total assets are usually used because asset totals can vary throughout the year. Simply add the beginning and ending assets together on the balance sheet and divide by two to calculate the average assets for the year. The net income can be found on the income statement

In this case, the company invests money into capital assets and the return is measured in profits.

In short, this ratio measures how profitable a company’s assets are.
