How to Make an Income Statement Step-by-Step

An income statement, often called a profit and loss (P&L) statement, summarizes a company’s financial performance over a specific period. This document details revenues, expenses, gains, and losses, ultimately arriving at a net profit or loss. It offers insight into a business’s operational efficiency and overall profitability. The income statement is one of three primary financial statements, working alongside the balance sheet and cash flow statement to provide a comprehensive view of a company’s financial health.

Identifying Essential Components

Understanding the core components of an income statement is essential. Revenue represents the total money a company earns from its primary business activities, such as selling goods or services, and appears at the top of the statement. This figure reflects the gross proceeds before any expenses are considered.

Cost of Goods Sold (COGS) includes the direct costs incurred in producing goods sold or services rendered. These costs encompass raw materials, direct labor, and manufacturing overhead. Subtracting COGS from revenue yields Gross Profit, which indicates the profit generated from sales before considering operating expenses.

Operating Expenses are the costs associated with running a business’s day-to-day operations not directly tied to production. Examples include salaries and wages, rent, utility bills, marketing costs, and depreciation. Deducting operating expenses from gross profit results in Operating Income, revealing the profitability of a company’s core business activities before interest and taxes.

Non-Operating Income and Expenses arise from activities outside a company’s primary business operations. Interest income from investments or interest expense on debt are common examples. Gains or losses from asset sales also fall into this category. After accounting for these non-operating items, the remaining amount is Income Before Taxes.

Income Tax Expense represents the taxes a company owes on its earnings, calculated based on the income before taxes. Deducting this expense leads to Net Income, often called the “bottom line,” as it represents the company’s total profit after all expenses, including taxes, have been accounted for.

Gathering Financial Data

Collecting the necessary financial data is an essential step in constructing an accurate income statement. Revenue figures, representing total sales of goods or services, can be sourced from sales records, customer invoices, and point-of-sale (POS) systems.

Information for Cost of Goods Sold comes from purchase invoices for raw materials or inventory, alongside inventory management records. Detailed records of direct labor costs, often found in payroll systems, are also crucial for accurately calculating COGS.

Operating expenses are compiled from various sources across the business. Payroll records provide data for salaries and wages, while rent agreements and utility bills offer precise amounts for occupancy costs. Marketing expenses are traceable through advertising invoices and campaign spending reports. Asset registers and depreciation schedules determine depreciation expense for tangible assets.

Non-operating income and expenses require review of specific financial instruments and transaction records. Interest income details are found on bank statements or investment account summaries. Interest expense figures are pulled directly from loan agreements and statements from lenders. Documentation for asset sales, including original cost and sale price, is necessary to determine any gains or losses.

Calculating Key Figures

The first major calculation is Gross Profit, determined by subtracting the Cost of Goods Sold (COGS) from Revenue. For example, if revenue is $500,000 and COGS is $200,000, gross profit is $300,000. This reflects the profitability of core production or service delivery before other operational costs.

Next, Operating Income is calculated by subtracting total Operating Expenses from Gross Profit. This involves summing expenses like salaries, rent, utilities, marketing, and depreciation. If gross profit is $300,000 and operating expenses are $150,000, operating income is $150,000. This figure provides insight into the efficiency of a company’s primary business operations.

Income Before Taxes is then derived by adjusting Operating Income for Non-Operating Income or Expenses. This involves adding non-operating income (e.g., interest earned) and subtracting non-operating expenses (e.g., interest paid or asset sale losses). For instance, if operating income is $150,000, with $5,000 in interest income and $10,000 in interest expense, income before taxes is $145,000.

Finally, Income Tax Expense is calculated based on the Income Before Taxes, typically by applying the applicable corporate income tax rate. If income before taxes is $145,000 and the tax rate is 21%, the tax expense is $30,450. Subtracting this tax expense from Income Before Taxes yields Net Income, the final profit after all costs and taxes. In this example, net income is $114,550.

Assembling the Statement

The final step involves assembling these figures into a structured income statement. The multi-step format is commonly used for its clarity, systematically presenting profitability at various stages. This structure begins with the revenue earned from sales or services at the top.

Following revenue, the Cost of Goods Sold is presented and subtracted to arrive at the Gross Profit. This subtotal provides an immediate view of profitability from core sales activities. Below gross profit, all operating expenses are listed, typically grouped by their nature, such as salaries, rent, utilities, and marketing costs. These expenses are totaled and subtracted from gross profit to show the Operating Income.

Subsequently, non-operating income and expenses are detailed. These items, such as interest income, interest expense, or gains and losses from asset sales, are added or subtracted from the operating income. This leads to the subtotal of Income Before Taxes. The income tax expense is then presented and subtracted to reach Net Income, positioned at the very bottom of the statement.

The income statement must clearly indicate the reporting period it covers, such as a fiscal quarter or year, and specify the currency used. Professional presentation ensures the financial performance is easily understandable for stakeholders to assess profitability and operational effectiveness over the defined period.
