How Do I Calculate ROE?

The formula for ROE is:

Return on Equity = Net Profit ÷ Shareholders’ Equity

Or for Monolithic Power Systems:

16% = US$105m ÷ US$640m (Based on the trailing twelve months to December 2018.)

It’s easy to understand the ‘net profit’ part of that equation, but ‘shareholders’ equity’ requires further explanation. It is the capital paid in by shareholders, plus any retained earnings. You can calculate shareholders’ equity by subtracting the company’s total liabilities from its total assets.

What Does Return On Equity Signify?

Return on Equity measures a company’s profitability against the profit it has kept for the business (plus any capital injections). The ‘return’ is the yearly profit. That means that the higher the ROE, the more profitable the company is. So, as a general rule, a high ROE is a good thing. That means ROE can be used to compare two businesses.

Does Monolithic Power Systems Have A Good ROE?

Importantly, this is far from a perfect measure, because companies differ significantly within the same industry classification.

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 and second cases, the ROE will reflect this use of cash for investment in the business. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders’ equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.

Combining Monolithic Power Systems’s Debt And Its 16% Return On Equity

Monolithic Power Systems is free of net debt, which is a positive for shareholders. Its respectable ROE suggests it is a business worth watching, but it’s even better the company achieved this without leverage. After all, with cash on the balance sheet, a company has a lot more optionality in good times and bad.

In Summary

Return on equity is a useful indicator of the ability of a business to generate profits and return them to shareholders. Companies that can achieve high returns on equity without too much debt are generally of good quality. If two companies have around the same level of debt to equity, and one has a higher ROE, I’d generally prefer the one with higher ROE.

But when a business is high quality, the market often bids it up to a price that reflects this. It is important to consider other factors, such as future profit growth — and how much investment is required going forward. So you might want to take a peek at this data-rich interactive graph of forecasts for the company.
