The income statement presents all the income and expenses a company incurs over a period of time. An analyst can analyze the statement with the use of various ratios to assess the company’s performance over time and make forecasts/predictions. The most common ratios are:

On their own, these ratios won’t offer more than just a number. Instead, they can be used as comparable metrics by comparing a company’s profitability from one year to the next or with a competitor for the same period.

To demonstrate these ratios, let’s look at the comparison between two similar companies. We’ll use Coca-Cola vs Pepsi for the year-ended 2017:

The first step is to review the income statements and identify the items needed for the margin calculations.

Operating Margin

Operating margin is a profitability ratio and measures how much profit a company makes per one dollar of sales. We need to identify two items for this calculation, the reported revenue and operating profit for the year ended 2017. For Coca-Cola, this is presented as the operating income but means the same figure. The data is reported below:

The operating margin is calculated by dividing the reported operating profit by the sales for that period. The results show that for every 100 dollars of profit made, $21 dollars is contributing towards Coca-Cola’s operating profit and $17 dollars towards Pepsi’s. This shows that Coca-Cola are managing their costs more efficiently to generate a profit. Pepsi who operate in a similar industry will want to review their pricing strategy and direct materials costs.

Net Income Margin

Net income is the total profit available after all expenses have been deducted for the period. The net income margin shows the percentage of revenue left after all expenses have been deducted. This is another profitability ratio which measures the amount of net income generated in relation to a company’s sales.

EBIT Margin

Earnings before interest or tax (EBIT) is a calculated figure which shows the profitability of a company from its operations after excluding non-recurring items. Excluding these items can improve comparisons with competitors as well as providing a useful starting point for predicting future profitability.

For many companies, this figure may be the same as operating profit and it’s up to the analyst to decide which items need adjusting to generate a “clean EBIT” figure. The calculation starts with operating profit and adjustments are made for any deemed non-recurring items.

For Coca-Cola, there is a line item in their income statement called “other operating charges”. It is not clear what this item includes and is a good place to start.

The MD&A or footnotes usually provide us with more information on these items. Below is an extract from Coca-Cola’s 8-K report, which highlights non-recurring items identified by management including the amounts involved in other operating charges.

For PepsiCo, the income statement itself doesn’t highlight any non-recurring items. However, the MD&A does provide some detail on these, as shown in PepsiCo’s 8-K extract below.

We now need to decide which items above we view as non-recurring. We then add them back to the operating profit line for a “clean EBIT” figure.

The table below includes the reported operating profit with a list of all the non-recurring items that can be added back to the earnings figure. The adjusted operating profit figure shows a large increase for Coca-Cola in comparison to the operating profit margin (21% to 27%). This shows the profitability generated from operations is much greater when excluding non-recurring items, as the company is undergoing a large restructuring program.

PepsiCo only had one item added back to their operating profit figure. Due to their high sales figure for the period, this made little difference to the margin (remains at 17%).


Earnings before interest, tax, interest, depreciation and amortization is calculated by taking our EBIT number and adding back the expenses relating to long lived assets. Companies may have different depreciation and amortization policies for these assets, resulting in a larger (or smaller) expense. This will in turn reduce (or increase) their EBIT. Adding back these expenses can make it easier to compare with competitors.

The EBIT figure has already been calculated, so the depreciation and amortization expense (“D&A”) needs to be identified from the statements and added back. The figures can be found in the statement of cash flows under operating activities.

The table below shows the EBITDA figure calculation using our EBIT figure from above and the reported D&A figure. The margin can be calculated by dividing EBITDA by the sales for the same period.

We notice that Coca-Cola has an EBITDA margin of 31%, which is higher than the PepsiCo’s EBITDA margin of 21%.
