What Is an Income Statement and How Do You Create One?

An income statement is a fundamental financial document that summarizes a company's revenues and expenses over a specific period, ultimately revealing its net profit or loss. It is essential for internal decision-making and external stakeholder analysis, providing a clear picture of operational efficiency and profitability.

How Does an Income Statement Guide Business Decisions? For business owners and managers, the income statement acts as a report card on the company's financial health. It enables informed decisions regarding spending on areas like marketing or hiring by showing the direct impact of these costs on the bottom line. Externally, it provides investors and creditors with the data needed to assess the company's growth potential and ability to generate returns or repay loans. According to mainstream financial reporting standards, an income statement typically includes the following components, moving from top-line revenue to bottom-line net income:

• Revenue (or Sales): This is the gross total income generated from the sale of goods or services before any expenses are deducted.
• Cost of Goods Sold (COGS): These are the direct costs attributable to the production of the goods or services sold by a company, including materials and direct labor.
• Gross Profit: Calculated as Revenue minus COGS, this figure indicates the efficiency of production processes.
• Operating Expenses: This category includes Selling, General & Administrative (SG&A) expenses, such as marketing, salaries for administrative staff, rent, and utilities.
• Operating Income: This is the profit remaining after all operating expenses are subtracted from the gross profit.
• Non-Operating Expenses: Items like interest expense on loans fall under this category.
• Pre-Tax Income: Also known as Earnings Before Tax (EBT), this is the final subtotal before taxes are applied.
• Net Income: This is the final profit or loss after all expenses, including taxes, have been subtracted from total revenue.

What Are the Key Steps to Creating an Income Statement? Creating an accurate income statement involves a formulaic process that starts with data from your accounting records. Based on our assessment experience, the following steps provide a reliable framework:

1. Choose a Reporting Period: Determine the timeframe the statement will cover (e.g., monthly, quarterly, or annually).
2. Generate a Trial Balance: This internal report lists the end-of-period balances for all accounts, ensuring debits and credits match.
3. Calculate Total Revenue: Aggregate all revenue from sales and other income sources for the period.
4. Determine Cost of Goods Sold: Tally all direct costs associated with production.
5. Calculate Gross Profit: Subtract COGS from Total Revenue.
6. Tally Operating Expenses: Sum all SG&A expenses.
7. Calculate Operating Income: Subtract Operating Expenses from Gross Profit.
8. Account for Interest and Taxes: Subtract interest expenses to find Pre-Tax Income, then calculate and subtract the applicable corporate tax.
9. Arrive at Net Income: The final figure is the profit or loss after all deductions.

Single-Step vs. Multi-Step Income Statement: Which Format is Right for You? The choice of format depends on the detail required for analysis. A single-step income statement is simpler, grouping all revenues and all expenses, and is suitable for a quick overview. A multi-step income statement provides greater detail by separating operating activities from non-operating activities and calculating gross profit and operating income separately. This format is more useful for in-depth financial analysis.

To leverage the income statement effectively, focus on these core takeaways: track trends over time to identify patterns, use the multi-step format for deeper insights into operational efficiency, and ensure accuracy by reconciling with your trial balance. This document is not just a historical record but a vital tool for shaping future business strategy.
