Decoding Business Success: A Closer Look at DuPont Analysis

Warren Buffett always prioritizes one key ratio in a business: Return on Equity.


You: But why? Isn't this a simple ratio: Net Profit divided by Shareholder's Equity?

Yes, it is a straightforward calculation. However, it doesn't provide us with a complete picture of the business.

You: So why does he (Mr. Warren Buffett) use this?

Because he employs DuPont analysis to gain a deeper understanding of the business.

You: What makes DuPont analysis special?

DuPont analysis breaks down the Return on Equity into its components, offering insights into the sources of a company's profitability and efficiency.

Net Profit Margin: It measures a company's profitability by expressing net income as a percentage of revenue.

Asset Turnover Ratio: It evaluates a company's efficiency in generating revenue from its assets.

Equity Multiplier: It assesses the proportion of a company's assets financed by shareholders' equity versus debt.

By utilizing DuPont analysis, we can discern the specific factors influencing the Business Return on Equity.

Increasing margins and efficiency typically indicate positive growth and management effectiveness, while excessive reliance on debt financing could potentially pose risks to the business's stability.

- Below is the DuPont analysis of Kalyan Jewellers, offering insights into their business profitability.

1. Net Profit Margin (A):

- In Mar-18, the net profit margin was 1.04%, which means the company earned a profit of 1.04 paisa for every rupee of revenue.

- In Mar-23, the net profit margin improved significantly to 3.04%, indicating a higher level of profitability compared to previous years.

- The net Profit margin over the years shows fluctuations.

2. Asset Turnover Ratio (B):

- In Mar-18, the asset turnover ratio was 1.23x, indicating that the company generated Rs 1.23 of revenue for every rupee of assets.

- In Mar-23, the asset turnover ratio increased to 1.43x, suggesting improved efficiency in asset utilization.

- It showed a stable trend over the years but in recent years it shot up due to Higher sales.

3. Equity Multiplier (C):

- In Mar-18, the equity multiplier was 101.90x, indicating high financial leverage, with total assets being significantly higher than shareholder equity.

- In Mar-23, the equity multiplier decreased to 95.42x, suggesting a reduction in financial leverage.

- It showed a declining trend in recent years because the company’s total assets are increasing indicating a strong balance sheet.

4. Return on Equity (ROE): This is calculated as the product of net profit margin, asset turnover ratio, and equity multiplier.

- Using the DuPont equation, we can calculate ROE for each year:

- Mar-18: ROE = 1.04% * 1.23x * 101.90x = 129.58%

- Mar-23: ROE = 3.04% * 1.43x * 95.42x = 414.81%

- ROE improved significantly from Mar-18 to Mar-23, driven by improvements in net profit margin, asset turnover ratio, and a decrease in the equity multiplier.

In summary, the DuPont analysis helps in understanding the drivers of changes in ROE over time. In this case, the company's improved profitability, efficient asset utilization, and changes in financial leverage contributed to the significant improvement in ROE from Mar-18 to Mar-23.
