How Is ROE Calculated?

The formula for return on equity is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for SG Fleet Group is:

9.1% = AU$48m ÷ AU$529m (Based on the trailing twelve months to December 2021).

The 'return' is the profit over the last twelve months. So, this means that for every A$1 of its shareholder's investments, the company generates a profit of A$0.09.

Does SG Fleet Group Have A Good ROE?

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 is clear from the image below, SG Fleet Group has a better ROE than the average (7.0%) in the Commercial Services industry.

That is a good sign. Bear in mind, a high ROE doesn't always mean superior financial performance. Especially when a firm uses high levels of debt to finance its debt which may boost its ROE but the high leverage puts the company at risk.

How Does Debt Impact ROE?

Virtually all companies need money to invest in the business, to grow profits. That cash can come from issuing shares, retained earnings, or debt. In the first and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt used for growth will improve returns, but won't affect the total equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

SG Fleet Group's Debt And Its 9.1% ROE

It seems that SG Fleet Group uses a huge volume of debt to fund the business, since it has an extremely high debt to equity ratio of 3.05. Most investors would need a low share price to be interested in a company with low ROE and high debt to equity.
