How To Calculate Return On Equity?

Return on equity can be calculated by using the formula:

Does Tohoku Electric Power Company Have A Good Return On Equity?

Arguably the easiest way to assess company's ROE is to compare it with the average in its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As you can see in the graphic below, Tohoku Electric Power Company has a higher ROE than the average (19%) in the Electric Utilities industry.

That's what we like to see. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. A higher proportion of debt in a company's capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

Why You Should Consider Debt When Looking At ROE

Most companies need money -- from somewhere -- to grow their profits. The cash for investment can come from prior year profits (retained earnings), issuing new shares, or borrowing. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. Thus the use of debt can improve ROE, albeit along with extra risk in the case of stormy weather, metaphorically speaking.

Tohoku Electric Power Company's Debt And Its 37% ROE

We think Tohoku Electric Power Company uses a significant amount of debt to maximize its returns, as it has a significantly higher debt to equity ratio of 4.00. Its ROE is clearly quite good, but it seems to be boosted by the significant use of debt by the company.
