## What Is the DuPont Analysis?

The DuPont analysis (also known as the DuPont identity or DuPont model) is a framework for analyzing fundamental performance popularized by the DuPont Corporation. DuPont analysis is a useful technique used to decompose the different drivers of return on equity (ROE). The decomposition of ROE allows investors to focus on the key metrics of financial performance individually to identify strengths and weaknesses.

### Key Takeaways

• The DuPont analysis is a framework for analyzing fundamental performance originally popularized by the DuPont Corporation.
• DuPont analysis is a useful technique used to decompose the different drivers of return on equity (ROE).
• An investor can use analysis like this to compare the operational efficiency of two similar firms. Managers can use DuPont analysis to identify strengths or weaknesses that should be addressed.

## Formula and Calculation of DuPont Analysis

The Dupont analysis is an expanded return on equity formula, calculated by multiplying the net profit margin by the asset turnover by the equity multiplier.

﻿ \begin{aligned} &\text{DuPont Analysis} = \text{Net Profit Margin} \times \text{AT} \times \text{EM} \\ &\textbf{where:}\\ &\text{Net Profit Margin} = \frac{ \text{Net Income} }{ \text{Revenue} } \\ &\text{AT} = \text{Asset turnover} \\ &\text{Asset Turnover} = \frac{ \text{Sales} }{ \text{Average Total Assets} } \\ &\text{EM} = \text{Equity multiplier} \\ &\text{Equity Multiplier} = \frac{ \text{Average Total Assets} }{ \text{Average Shareholders' Equity} } \\ \end{aligned}﻿

## What DuPont Analysis Tells You

A DuPont analysis is used to evaluate the component parts of a company's return on equity (ROE). This allows an investor to determine what financial activities are contributing the most to the changes in ROE. An investor can use analysis like this to compare the operational efficiency of two similar firms. Managers can use DuPont analysis to identify strengths or weaknesses that should be addressed.

There are three major financial metrics that drive return on equity (ROE): operating efficiency, asset use efficiency, and financial leverage. Operating efficiency is represented by net profit margin or net income divided by total sales or revenue. Asset use efficiency is measured by the asset turnover ratio. Leverage is measured by the equity multiplier, which is equal to average assets divided by average equity.

## DuPont Analysis Components

DuPont analysis breaks ROE into its constituent components to determine which of these factors are most responsible for changes in ROE.

### Net Profit Margin

The net profit margin is the ratio of bottom line profits compared to total revenue or total sales. This is one of the most basic measures of profitability.

One way to think about the net margin is to imagine a store that sells a single product for $1.00. After the costs associated with buying inventory, maintaining a location, paying employees, taxes, interest, and other expenses, the store owner keeps$0.15 in profit from each unit sold. That means the owner's profit margin is 15%, which can be calculated as follows:

﻿ \begin{aligned} &\text{Profit Margin} = \frac{ \text{Net Income} }{ \text{Revenue} } = \frac{ \0.15 }{ \1.00 } = 15\% \\ \end{aligned}﻿

The profit margin can be improved if costs for the owner were reduced or if prices were raised, which can have a large impact on ROE. This is one of the reasons that a company's stock will experience high levels of volatility when management makes a change to its guidance for future margins, costs, and prices.

### Asset Turnover Ratio

The asset turnover ratio measures how efficiently a company uses its assets to generate revenue. Imagine a company had $100 of assets, and it made$1,000 of total revenue last year. The assets generated 10 times their value in total revenue, which is the same as the asset turnover ratio and can be calculated as follows:

﻿ \begin{aligned} &\text{Asset Turnover Ratio} = \frac{ \text{Revenue} }{ \text{Average Assets} } = \frac{ \1,000 }{ \100 } = 10 \\ \end{aligned}﻿

A normal asset turnover ratio will vary from one industry group to another. For example, a discount retailer or grocery store will generate a lot of revenue from its assets with a small margin, which will make the asset turnover ratio very large. On the other hand, a utility company owns very expensive fixed assets relative to its revenue, which will result in an asset turnover ratio that is much lower than that of a retail firm.

The ratio can be helpful when comparing two companies that are very similar. Because average assets include components like inventory, changes in this ratio can signal that sales are slowing down or speeding up earlier than it would show up in other financial measures. If a company's asset turnover rises, its ROE will improve.

## DuPont Analysis vs. ROE

The return on equity (ROE) metric is net income divided by shareholders’ equity. The Dupont analysis is still the ROE, just an expanded version. The ROE calculation alone reveals how well a company utilizes capital from shareholders.

With a Dupont analysis, investors and analysts can dig into what drives changes in ROE, or why an ROE is considered high or low. That is, a Dupont analysis can help deduce whether its profitability, use of assets, or debt that’s driving ROE.

## Limitations of Using DuPont Analysis

The biggest drawback of the DuPont analysis is that, while expansive, it still relies on accounting equations and data that can be manipulated. Plus, even with its comprehensiveness, the Dupont analysis lacks context as to why the individual ratios are high or low, or even whether they should be considered high or low at all.

### What is the difference between 3-step and 5-step DuPont analysis?

There are two versions of DuPont analysis, one utilizing decomposition of ROE via 3 steps and another utilizing 5 steps. The three-step equation breaks up ROE into three very important components:

\begin{aligned} &\text{ROE} = \frac{ \text{Net Income} }{ \text{Sales} } \times \frac{ \text{Sales} }{ \text{Assets} } \times \frac{ \text{Assets} }{ \text{Shareholders' Equity} } \\ \end{aligned}

\begin{aligned} &\text{ROE} = \frac{ \text{EBT} }{ \text{S} } \times \frac{ \text{S} }{ \text{A} } \times \frac{ \text{A} }{ \text{E} } \times ( 1 - \text{TR} ) \\ &\textbf{where:} \\ &\text{EBT} = \text{Earnings before tax} \\ &\text{S} = \text{Sales} \\ &\text{A} = \text{Assets} \\ &\text{E} = \text{Equity} \\ &\text{TR} = \text{Tax rate} \\ \end{aligned}
