One of the best investments we can make is in our own knowledge and skill set. With that in mind, this article will work through how we can use Return On Equity (ROE) to better understand a business. By way of learning-by-doing, we'll look at ROE to gain a better understanding of Spark New Zealand Limited (NZSE:SPK).
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.
How Is ROE Calculated?
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Spark New Zealand is:
14% = NZ$194m ÷ NZ$1.4b (Based on the trailing twelve months to December 2024).
The 'return' is the income the business earned over the last year. So, this means that for every NZ$1 of its shareholder's investments, the company generates a profit of NZ$0.14.

Does Spark New Zealand Have A Good Return On Equity?
One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. However, this method is only useful as a rough check, because companies do differ quite a bit within the same industry classification. As is clear from the image below, Spark New Zealand has a better ROE than the average (11%) in the Telecom industry.
That's clearly a positive. However, bear in mind that a high ROE doesn’t necessarily indicate efficient profit generation. 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.

Why You Should Consider Debt When Looking At ROE
Companies usually need to invest money to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the first two cases, the ROE will capture this use of capital to grow. In the latter case, the use of debt will improve the returns, but will not change the equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
Combining Spark New Zealand's Debt And Its 14% Return On Equity
Spark New Zealand does use a high amount of debt to increase returns. It has a debt to equity ratio of 1.30. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.
