What are the key things that you want to do when you use ratios?
When calculating ratios that include both balance sheet and income statement amounts, we generally use an average of beginning and ending balances for the balance sheet amount.
What is ROE (Return on Equity) & The DuPont Framework?

Return on equity = (net income) / (total owners’ equity)
Return on equity = profitability x operating efficiency x financial leverage
What is the DuPont Framework and what does it measure?
The DuPont Framework expands the ROE formula to consist of three measures:
For any one company, a higher ROE is generally better than a lower ROE.

PROFIT MARGIN FORMULA
The first section of the DuPont Framework, profitability, reveals how much profit is left from each dollar of sales after all expenses have been subtracted.
For H&M in the year 2012, the profit margin was 13.96%. In other words, for every hundred Swedish krona of sales that H&M had, 14 ended up in the net income for the period. Profit margin is an important measure.
A high net profit margin means a company keeps a large proportion of its revenue as profit, so it is better to have a high net profit margin than a low or negative net profit margin. (google)

The Profitability or Profit Margin is calculated by dividing the Net Income by the Revenue. In this case, the calculation is as follows:
Net Income / Revenue = 483,232 / 4,358,100 = 11.09%
The suggested correct answer formula is:
=C9/C4

The Profitability or Profit Margin is calculated by dividing the Net Income by the Revenue. In this case, the calculation is as follows:
Net Income / Revenue = 37,037 / 170,910 = 21.67%
The trick is to recognize that the Revenue is equal to the Cost of Sales plus the Gross Profit (170,910 = 106,606 + 64,304). As we have learned, Revenue minus Cost of Sales equals Gross Profit so it follows that Cost of Sales plus Gross Profit equals Revenue.
The suggested correct answer formula is:
=C12/(C6+C7)
Which of the following ratios measures the ability of a company to make a profit relative to the revenue generated during the period?
How do you calculate the profit margin ratio within the DuPont Framework?
Suppose the profit margin for Cardullo’s Gourmet Shoppe, Inc for Q1 was 4.99% and Q2 was 10.57%. Which of the following statements can you conclude regarding Cardullo’s?
The profit margin for East Corp. for each year from 2011 to 2013 is listed below.
2011: 7.13%
2012: 7.68%
2013: 8.14%
Which of the following is NOT a reasonable explanation for the trend in the ratio?
What is the purpose of Gross Profit Margin and what’s the formula?
Gross Profit Margin- Profitability Ratios
When the profit margin is used to determine profitability using the DuPont Framework, other ratios are also very useful. One of those is the gross profit margin. We’ve already talked about gross profit being revenues minus the cost of goods sold. This ratio is simply converting the numbers into a percentage– gross profit divided by sales. **This tells us what percentage of revenue is left to cover other expenses after the cost of goods sold is subtracted.
Gross Profit Margin = GROSS PROFIT / SALES**
*These values are taken from the income statement

What are the two Profitability Ratios?

Gross Profit Margin is calculated by dividing the Gross Profit (Revenue less Cost of Sales) by the Revenue. In this case, the calculation is as follows:
(Revenue - Cost of Sales) / Revenue = Gross Profit Margin
(170,910 - 106,606) / 170,910 = 37.62%
The suggested correct answer formula is:
=(B1-B4)/B1

Gross Profit Margin is calculated by dividing the Gross Profit by the Revenue. In this case, the calculation is as follows:
Gross Profit / Revenue = 1,619,386 / 4,358,100 = 37.16%
The suggested correct answer formula is:
=B6/B4

Higher demand has allowed Amazon to increase their prices, while higher overhead expenses have been hurting overall profits.
Higher selling prices would result in a higher gross profit margin, but increasing operating expenses could eat away the profits before they hit the bottom line.
The gross profit margin for Amazon for each year from 2010 to 2012 is listed below.
2010: 22.35%
2011: 22.44%
2012: 24.75%
Which explanation below is a reasonable explanation for the trend in the ratio?
Suppose the following were the gross profit margins for Green Mountain Coffee Roasters (GMCR) from 2011 through 2013.
2011: 34.13%
2012: 32.89%
2013: 37.16%
Suppose the gross profit margin for Cardullo’s Gourmet Shoppe, Inc for Q1 was 47.25% and Q2 was 47.70%. Which of the following is a reasonable explanation for the change in the ratio?
What is… Earnings before interest after taxes, or EBIAT?
Earnings before interest after taxes, or EBIAT, is a measure of how much income the business has generated while ignoring the effect of financing and capital structure, or the proportion of debt that the business has. As the name implies, interest expense, which is included on the income statement, is added back, and income tax expense is calculated and subtracted based on earnings before interest.
For H&M, EBIAT for 2012 is 16.8 billion Swedish krona.We will not go further into calculating EBIAT now, but it is an important measure to understand as we will see it again in Module 7.

Define & List the Formula to Asset Turnover
This tells us how well a business is using its assets to produce sales. Initially, it may seem like it is good for a business to have many assets. However, from an efficiency perspective, this isn’t the case. A business that can create more revenue with fewer assets is more efficient.
ASSET TURNOVER = SALES / ASSETS
*These values are taken from the income statement & the balance sheet
H&M’s asset turnover for 2012 was 2.01. This shows that H&M generated sales of about 2 krona on each krona of assets during the period. An interesting thing to note here is that _this ratio uses both the income statement and the balance sheet._ Because the income statement covers the entire year, but the balance sheet is as of a specific point in time, we typically use the average of the beginning and ending balance sheet amounts to estimate the average level of assets during the period.


Asset Turnover is calculated by dividing the annual revenue by the average asset value for the year. In this case, we are using a two-point average of beginning and end of year asset values so the calculation is as follows:
Revenue / Average Assets = 170,910 / 191,532 = 0.89
To calculate average assets, you are given the beginning total of $176,064 but you must calculate the ending total by summing all asset accounts as of Sept 28, 2013 (a shortcut would be to add the Liabilities and Equity at September 28, 2013, since we know A = L + OE). The ending total is $207,000 making the average $191,532.
There are several formulas that could help you arrive at the correct answer, but one solution is presented below:
=B17/AVERAGE(B14,SUM(B2:B9))
Name the Different Efficiency Ratios
Notice how again we used the average inventory balance instead of the ending balance that is typically displayed on the balance sheet. This is especially significant and provides better results than using the ending balance, especially for a firm that is growing quickly, as the level of inventory could have fluctuated during the year. We could further improve the accuracy by averaging more frequent inventory balances, such as quarterly or monthly, but for purposes of this course we’ll use the beginning and ending balances to determine average inventory.
