What is an income statement? Everything you need to know (2024)

An income statement, also known as a profit and loss statement (P&L statement), summarizes a business’s revenues and expenses over a period of time. It’s one of the most important financial statements for small business owners, so it’s key to understand what an income statement is, what its purpose is, and how to read one.

The hardest part? Knowing where to start, especially if you’re not a “numbers person.”

Luckily, we’re here to define what an income statement is and give a few examples of how small business owners can use them to make smart business decisions. By the end of this post, you’ll feel like an accounting pro. 😎

What is an income statement?

An income statement is an important financial statement that gives you a look into your business’s financial health and profitability for a specific period.

An income statement is one of three key financial statements for small business owners—the other two being your balance sheet and your cash flow statement. The income statement is the most important of the three (but don’t tell the others we said that).

With all three documents in hand, you’ll be able to determine whether you’re profitable or not—which investors will want to know, too!

What’s the purpose of an income statement?

Okay, we’ve made a bit of a fuss about income statements so far, so at this point you’re probably wondering: Why are income statements so important, anyway?

The main thing you can learn from an income statement is how much money your business earned, and how much money your business spent to earn it. Your income statement lets you see your business’s financial health, so you can set realistic and helpful goals and budgets for the future—and see if those efforts have been successful.

Using your learnings from an income statement, you can determine whether to expand your business, increase production, or, on the other hand, stop producing certain products or investing in specific parts of your business that might not have the best return on investment.

Who uses an income statement?

Your income statement can be used both internally by you and anyone else within your business, or externally by stakeholders.

For example, business managers, your board of directors, or simply just little ol’ you would use your income statement to evaluate your business’s performance and make decisions.

External stakeholders—like investors or creditors—will want to evaluate your income statement before deciding to work with you. The Internal Revenue Service (IRS) will also need to see an income statement to determine your total taxable business income.

The income statement vs. the balance sheet

Like an income statement, a balance sheet also gives you a look into your business’s finances for a specific period of time. However, balance sheets are usually for a specific date, while income statements are for longer periods, like a month, quarter, or year.

While your income statement shows you how profitable your business is, your balance sheet shows you how many assets you have, how much you owe others, and—ultimately—how much you have at the end.

What goes on an income statement?

Important note before we get into the components of an income statement: make sure you choose an accounting method first, and stick with it! Your accounting method will determine how you calculate your revenue, so you need to stay consistent.

If you’re using accrual-basis accounting, you’re reporting on revenue and expenses that haven’t yet been received or paid.

And if you’re using cash-basis accounting, you’re reporting revenue and expenses only when they have actually been received or paid.

Okay, caveat over. Let’s get into the five key parts of a standard income statement, and how you can prepare an income statement yourself. Buckle up!


Your revenue (aka income) is how much money your business earns from goods and services. This includes “operating” revenue, which is the revenue you make from selling goods and services, and “non-operating” revenue, which you make through behind-the-scenes operations, like maintenance.

To find your revenue, list out and add up your total income from goods or services. If you sell multiple goods or services, you can organize your sales by subcategory.

Cost of goods sold (COGS)

Cost of goods sold (COGS) is how much it costs your business to make the products or deliver the services you sell. COGS only refers to direct expenses (think: purchasing inventory or raw materials). To get your COGS, list out and add the total costs that are directly related to your goods/services.

Gross profit

Equation time! Gross profit is your revenue or income minus the COGS. At this point, your gross profit will tell you how profitable your business is, with only direct expenses being considered.

Operating expenses

Operating expenses are expenses for your business that aren’t directly part of the costs of a product or service. These can include payroll, rent, interest, insurance, Internet, and more. Again, it might be helpful to create categories for each type of these costs.

Net profit

Now, take your gross profit and subtract operating expenses, and you’ll get your net profit—aka your “bottom line.” Yay!

With net profit, you’ll be able to answer key questions, like: Is your business making or losing money? And can you really afford that new coffee machine for your office this year?

How to prepare an income statement

Next, let’s bring all this info together and walk you through how to prepare an income statement.

  1. At the top of the report, start with income (aka “revenue”).
  2. Next, add up your cost of goods sold.
  3. Now, take the income amount and subtract the cost of goods sold to get the gross profit number.
  4. Below that, add up your operating expenses.
  5. And finally, we take the gross profit and subtract the operating expenses to get the net profit.

Psst—you can easily generate an income statement using Wave’s accounting software!

How to read an income statement

Okay, so now you have a nifty income statement. But what can you learn from it?

For an income statement of a specific timeframe, there are some key learnings you can get, including:

  • How much your business earned from sales
  • How much your business spent on expenses
  • How profitable your business is
  • Where you can reduce expenses to become more efficient

Building income statements monthly and reviewing them over time helps you understand long-term trends like:

  • Whether your business is becoming more profitable
  • How your sales are changing
  • How your expenses are changing
  • Whether you’re becoming more efficient with your business expenses versus your business income

All of these learnings—both on their own and together—can help you make smart money decisions as a business owner.

Expert Introduction: As an expert in finance and accounting, I have a deep understanding of income statements, also known as profit and loss statements (P&L statements). I have practical experience in preparing, analyzing, and interpreting income statements for businesses of various sizes and industries. My expertise extends to explaining the purpose of income statements, the components that make up an income statement, and how to read and interpret the information presented in this financial statement.

Income Statement Overview: An income statement, or profit and loss statement, is a crucial financial document that provides a comprehensive summary of a business's revenues and expenses over a specific period. It is an essential tool for small business owners to assess their financial health and profitability. The income statement is one of the three key financial statements, alongside the balance sheet and cash flow statement, and it plays a pivotal role in determining a business's overall performance and viability.

Purpose of an Income Statement: The primary purpose of an income statement is to reveal how much money a business has earned and how much it has spent to earn that income. By analyzing the information presented in an income statement, business owners can gain insights into their financial health, set realistic goals and budgets, and make informed decisions about business expansion, production, and resource allocation. Additionally, external stakeholders such as investors, creditors, and the Internal Revenue Service (IRS) utilize income statements to evaluate a business's performance and taxable income.

Users of an Income Statement: An income statement is used both internally by business managers and externally by stakeholders, including investors, creditors, and the IRS. Internally, it helps in evaluating business performance and making strategic decisions, while externally, it serves as a crucial tool for assessing the financial viability of a business before entering into partnerships or transactions.

Income Statement vs. Balance Sheet: While an income statement provides a snapshot of a business's financial performance over a specific period, a balance sheet offers a detailed overview of a business's financial position at a specific point in time. The income statement focuses on profitability, while the balance sheet emphasizes assets, liabilities, and equity.

Components of an Income Statement: An income statement typically consists of five key parts: revenue/income, cost of goods sold (COGS), gross profit, operating expenses, and net profit. These components collectively provide a comprehensive view of a business's financial performance and profitability. It is essential for businesses to choose an accounting method, either accrual-basis or cash-basis, and maintain consistency in reporting revenue and expenses.

Preparing and Reading an Income Statement: The process of preparing an income statement involves organizing revenue, calculating COGS, determining gross profit, listing operating expenses, and calculating net profit. Once the income statement is prepared, business owners can use it to gain insights into their sales, expenses, profitability, and efficiency. Regularly generating and analyzing income statements helps in understanding long-term trends and making informed financial decisions to ensure the business's success and sustainability.

In conclusion, understanding income statements is crucial for small business owners to assess their financial performance, make informed decisions, and communicate effectively with stakeholders.
