How Do You Calculate Return On Equity?
ROE can be calculated by using the formula:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity
So, based on the above formula, the ROE for Northrop Grumman is:
16% = US$2.4b ÷ US$15b (Based on the trailing twelve months to September 2024).
The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.16 in profit.
Does Northrop Grumman 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. Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification. As you can see in the graphic below, Northrop Grumman has a higher ROE than the average (12%) in the Aerospace & Defense industry.
That's clearly a positive. 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 Return On Equity?
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 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 Northrop Grumman's Debt And Its 16% Return On Equity
Northrop Grumman clearly uses a high amount of debt to boost returns, as it has a debt to equity ratio of 1.10. While its ROE is pretty respectable, the amount of debt the company is carrying currently is not ideal. Debt does bring extra risk, so it's only really worthwhile when a company generates some decent returns from it.
