What Is An Income Statement?

An income statement, also called a profit and loss (P&L) statement, summarizes a company’s revenues, expenses, and net income over a specific period of time, such as a quarter or year. It provides a snapshot of a company’s financial performance and is one of the three main general purpose financial statements, along with the balance sheet and cash flow statement.

The income statement primarily focuses on the company’s operating performance particularly how much profit it generated from its core business operations. By subtracting expenses from revenues, you can calculate a company’s net profit or loss over the period being reported.

Income statements are usually prepared on a monthly, quarterly, and annual basis. Public companies are required to file quarterly and annual income statements with regulators like the SEC. Looking at income statements over several periods helps identify financial trends and growth.

Key Sections of an Income Statement

While income statements vary in appearance, they generally include the same key components:

Revenue

This section shows the total revenues earned by the company from its operations and other income sources over the reporting period. Revenues are usually broken out into categories like sales of products or services.

Cost of Goods Sold (COGS)

COGS refers to the direct expenses involved in producing the goods or services sold by the company. This includes things like raw material costs, labor, and manufacturing overhead. Subtracting COGS from revenue yields a company’s gross profit.

Operating Expenses

These are a company’s expenses related to normal business operations, excluding COGS. Common line items include things like:

• Research and development (R&D)
• Sales, general and administrative (SG&A) expenses
• Depreciation and amortization

Operating Income

Also called operating profit, this is the profit earned from core business operations and is calculated by subtracting operating expenses from gross profit.

Other Income and Expenses

Other revenue sources (like interest income) and expenses (like interest expense) not related to the core business operations are listed here.

Income Tax Expense

This line item represents the total income tax owed by the company over the reporting period.

Net Income

Also known as net profit or net earnings, this is the company’s total profits after subtracting all expenses and taxes from total revenues. It represents the final bottom line for the company.

How to Read an Income Statement

When reviewing an income statement, it helps to follow these steps:

1. Identify the reporting period. Income statements reflect performance over a specific time, such as a quarter or fiscal year. Make sure you know the covered time frame.

2. Check revenue trends. Look at the different revenue line items and how they changed compared to prior periods. Increasing revenue is a positive sign of business growth.

3. Review expenses. Analyze the major expense items like COGS and SG&A. Are certain expenses growing disproportionately to revenue? This could signal problems.

4. Assess profitability. Look at the various profitability metrics like gross, operating and net profit margins. Compare them to previous periods and industry benchmarks.

5. Note unusual items. Unusual gains or losses can skew results. Factor them in when evaluating performance.

6. Check footnotes. The footnotes contain useful details about accounting policies, acquisitions, segment performance and more that can provide greater insight when reading the statement.

Key Financial Metrics and Ratios

To perform an effective income statement analysis, focus on these key metrics and financial ratios:

Revenue Growth

This measures how much total revenue has increased over a period of time. Higher growth signals greater customer demand and market share gains.

Gross Profit Margin

Gross profit divided by total revenue. It shows how much gross profit is generated per dollar of revenue and reflects production efficiency.

Operating Profit Margin

Operating income as a percentage of total revenue. It measures profitability from core business operations.

Net Profit Margin

Net income divided by total revenue. It reflects overall company profitability after all expenses. Higher margins are better.

Earnings Per Share (EPS)

Net income divided by the number of outstanding shares. Increasing EPS helps drive share price.

Compare these ratios over time to identify positive or negative trends in a company’s financial performance. Also benchmark them against industry averages and key competitors.

Real-World Income Statement Example

Let’s look at a simplified example income statement for a fictional retail company, Superstore Inc:

Superstore Inc. Income Statement For the year ended Dec 31, 2022(in millions)Revenue  Product Sales   $550  Services Revenue       $50  Total Revenue       $600   COGS  Product COGS         $200   Services COGS       $10  Total COGS            $210  Gross Profit             $390Operating Expenses  Selling & Marketing $100  General & Administrative $50  Total Operating Expenses $150 Operating Income       $240  Other Expenses  Interest Expense      $20  Income Before Tax     $220  Income Tax Expense    $80  Net Income                $140 

In this example, we can see that Superstore earned $600 million in total revenue for the year. COGS totaled $210 million, resulting in a gross profit of $390 million. After operating expenses of $150 million, operating income was $240 million. Additional expenses and taxes resulted in a final net income of $140 million.

By dividing key metrics, we can analyze:

• Gross Profit Margin = Gross Profit/Revenue = $390M/$600M = 65%
• Operating Profit Margin = Operating Income/Revenue = $240M/$600M = 40%
• Net Profit Margin = Net Income/Revenue = $140M/$600M = 23%

Looking at the margins, we can see Superstore converted 65% of revenue into gross profit. Its operating and net margins are lower, but still relatively healthy. Comparing these metrics historically and to competitors would help further assess Superstore’s performance.

Tips for Better Income Statement Analysis

Here are some tips to improve your income statement analysis skills:

• Compare multiple periods – Look at 3-5 year trends to identify positive or negative momentum.

• Use common size ratios – Common size ratios like % of revenue provide better period-to-period comparability.

• Conduct vertical analysis – Evaluate line items as a % of total revenue to understand relative weight.

• Do horizontal analysis – Identify changes in income statement line items over time.

• Compare to competitors – Context is key. Benchmark against at least 3-5 peer companies.

• Adjust for one-time items – Factor out unusual gains, losses, and other one-time items to analyze core performance.

• Review footnotes and MD&A – Check the footnotes and management discussion and analysis for insight into results.

• Focus on key metrics – Pay closest attention to revenue growth, profit margins, and EPS trends.
