Return on Equity – Definition, Calculation and Formula of ROE

Return on Equity, or ROE, is a useful metric for gauging how well a company is using your money. It shows how effectively a company uses the money you and other shareholders invest to generate a profit. In this article, we'll go over what ROE means, look at some examples, and discuss what to be aware of. 

Key Highlights:

• ROE measures how efficiently a company uses shareholders' equity to generate profits.
• It is calculated by dividing Profit After Tax (PAT) by Net Worth.
• A higher ROE generally indicates better profitability and efficient use of shareholders' funds. 

What is Return on Equity (ROE)?

ROE shows how well a company uses the money its owners, or shareholders, put in. Shareholders own a piece of the company by buying its stock. 

The company then uses that money to operate, buy equipment, set up shops, hire staff, and so on. ROE tells you how much profit the company generates for every unit of money shareholders have invested. 

Let’s use a simple example:

Imagine you invest ₹10,000 to help your friend open a small tea stall. After one year, the business earns a profit of ₹2,000 after paying all expenses, such as rent, ingredients, and salaries. To understand how effectively your investment was used, you calculate the return earned on your money:

• Profit = ₹2,000
• Money invested = ₹10,000
• ROE = ₹2,000 ÷ ₹10,000 = 0.2 or 20%

This means your investment generated a 20% return, or ₹2,000 in profit for every ₹10,000 invested. Return on Equity (ROE) works the same way for companies; it measures how efficiently a business uses shareholders' money to generate profits. 

How Do You Calculate ROE?

Calculating ROE is simple once you know the two main numbers you need:

Profit After Tax (PAT): This is the money the company makes after paying all its expenses, taxes, and other costs. It’s the “net profit” left over.

Net Worth: This is the total amount of money that shareholders invest in the company, plus any profits the company has retained over the years.

The formula for ROE is:

ROE = Profit After Tax (PAT) ÷ Net Worth

Let’s break it down with an example:

Suppose a company called Happy Sweets Ltd. makes a profit of ₹2,000 crore after paying taxes. The shareholders have given the company ₹15,000 crore in total. 

To find the ROE:

• PAT = ₹2,000 crore
• Net Worth = ₹15,000 crore
• ROE = ₹2,000 ÷ ₹15,000 = 0.1333 or 13.33%

This means for every ₹100 of shareholders’ money, Happy Sweets Ltd. makes ₹13.33 in profit.

Understanding ROE Through DuPont Analysis 

If you want to calculate ROE yourself, you can find the numbers in a company’s financial statements, which are like its money report card. 

Here’s where to look:

• Profit After Tax (PAT): Check the company’s income statement. This document shows how much money the company earned, spent, and kept as profit.
• Net Worth: Look at the company’s balance sheet. Net worth is calculated as:

Net Worth = Equity Capital + Reserves and Surplus

• Equity Capital is the money shareholders paid to buy shares.
• Reserves and Surplus are the extra money the company saved from past profits.
• These reports are usually available on the company’s website or stock exchange websites.

A Deeper Look: The DuPont Analysis

ROE sounds simple, but there’s a clever way to break it down to understand why a company has a high or low ROE. This is called the DuPont Analysis, and it breaks down ROE into three components to give you a clearer picture. Don’t worry, it’s easier than it sounds.

The DuPont formula is:

ROE = Net Profit Margin × Total Asset Turnover × Equity Multiplier

Comparing Two Companies

Let’s look at two imaginary companies, Sunny Toys Ltd. and Happy Games Ltd., to see how ROE and DuPont Analysis work. Both companies make toys and are about the same size, but their ROE tells different stories.

Step 1: Calculate ROE

• Sunny Toys Ltd.
  • ROE = ₹2,400 ÷ ₹2,600 = 0.923 or 92.30%
• Happy Games Ltd.
  • ROE = ₹2,620 ÷ ₹5,000 = 0.524 or 52.40%

At first glance, Sunny Toys looks amazing because its ROE is much higher. But let’s use DuPont Analysis to dig deeper.

Step 2: DuPont Analysis

Let’s break down the ROE for both companies:

• Net Profit Margin:
  • Sunny Toys: ₹2,400 ÷ ₹12,000 = 0.2 or 20%
  • Happy Games: ₹2,620 ÷ ₹11,800 = 0.222 or 22%
  • Winner: Happy Games keeps more profit from each sale.
• Asset Turnover Ratio:
  • Sunny Toys: ₹12,000 ÷ ₹5,200 = 2.3
  • Happy Games: ₹11,800 ÷ ₹5,000 = 2.4
  • Winner: Happy Games uses its assets slightly better to make sales.
• Equity Multiplier:
  • Sunny Toys: ₹5,200 ÷ ₹2,600 = 2
  • Happy Games: ₹5,000 ÷ ₹5,000 = 1
  • Winner: Sunny Toys, because it uses debt to boost its ROE.

Step 3: What Does This Mean?

• Sunny Toys has a much higher ROE (92.30%) because it borrows money (has ₹2,600 crore in debt). This raises its equity multiplier, boosting ROE.
• Happy Games has no debt, so its equity multiplier is 1. Its ROE is lower (52.40%), but it’s safer because it doesn’t have to pay interest on loans.
• Happy Games is actually better at generating sales profits (higher profit margin) and using its assets (higher turnover), but Sunny Toys’ debt makes its ROE look better.

Step 4: Which Company is Better?

Sunny Toys appears more profitable due to its high ROE, but it’s riskier. If it can’t pay the interest on its ₹2,600 crore debt, it could get into trouble. 

Happy Games is safer because it doesn’t borrow money, but its ROE is lower. If you’re an investor, you might prefer Happy Games for safety or Sunny Toys if you’re okay with some risk for a higher return.

What Factors Affect ROE?

Several factors influence ROE and understanding them helps explain why one company generates higher returns than another. 

• Net Profit Margin: It is a metric that shows how much profit is generated for every one rupee of sales. The higher the value of the ratio, the better the company is at creating profits and controlling costs.
• Total Asset Turnover: It is a metric that determines how successfully the firm is generating sales from its assets. The higher the ratio, the more efficiently the company utilises its assets to generate revenue.
• Equity Multiplier: It is a metric that shows how much of the firm’s assets are financed by debt. The higher the value, the more debt is used to finance the company’s assets, and the more risky it is for shareholders.

Why Does ROE Matter?

Return on Equity (ROE) matters because it reflects a company's efficiency at using shareholders' money to generate profits. A consistently high ROE often indicates strong management, efficient use of capital, and better long-term growth potential, making it an important metric for evaluating a company's financial performance. 

• Helps choose good companies: If you want to invest in a company by buying its stock, ROE shows how well it generates profits. A higher ROE generally means the company is performing well.
• Lets you compare companies: You can use ROE to compare two companies in the same industry. For instance, if two companies sell clothes, the one with a higher ROE is likely better at generating profits from its investments.
• Indicates management effectiveness: The company's managers are responsible for using shareholder money effectively. A good ROE suggests they are doing a good job.
• Tracks performance over time: By looking at a company's ROE over several years, you can tell if its profit-making ability is improving or declining. 

Example: If a company’s ROE is 15% every year for five years, it’s probably a stable and reliable business. But if the ROE fluctuates, it might be risky.

Limitations of ROE

While ROE is a valuable measure of profitability, it should not be used in isolation, as it has a few important limitations.

• Can be inflated by high debt: A company with significant borrowings may report a high ROE even if its overall financial health is weak.
• Ignores debt levels: ROE focuses only on shareholders' equity and does not reflect the amount of debt the company has taken on.
• Less useful for comparing different industries: Since capital requirements vary across industries, ROE should be compared only within the same sector.
• Affected by one-time gains or losses: Exceptional income or expenses can temporarily increase or reduce ROE, giving a misleading picture.
• Negative equity can distort ROE: Companies with negative shareholders' equity may report an unusually high or meaningless ROE, making the ratio unreliable.

Tips for Using ROE Wisely

If you’re thinking about investing in a company, here’s how to use ROE smartly:

• Look for Consistency: A company with an ROE of 15%–20% for 5- 7 years is usually a good bet. Avoid companies with ROE that jump around a lot.
• Check the Industry: Compare a company’s ROE to others in the same business. A 10% ROE might be great for a bank but terrible for a tech company.
• Watch Out for Debt: Use DuPont Analysis to see if a high ROE comes from borrowing. If the equity multiplier is high, the company might be risky.
• Combine with Other Tools: ROE is just one number. Look at other things like profit growth, debt levels, and how the company is managed before investing.

Conclusion

Return on Equity, or ROE, is an important metric that shows how well a company uses the money its shareholders have invested. A high ROE usually means a company is profitable and well managed, but you shouldn't look at that alone. It's also best to check the company's debt, profit margins, and cash flow.
