The ROA figure gives investors an idea of how effectively the company is converting the money it has to invest into net income.
The higher the ROA number, the better, because the company is earning more money on less investment.
For example, if one company has a net income of $1 million and total assets of $5 million, its ROA is 20%; however, if another company earns the same amount but has total assets of $10 million, it has an ROA of 10%. Based on this example, the first company is better at converting its investment into profit. When you really think about it, management’s most important job is to make wise choices in allocating its resources. Anybody can make a profit by throwing a ton of money at a problem, but very few managers excel at making large profits with little investment.
