Introduction to the Income Statement
(also called the Statement of Earnings or Profit & Loss Statement)
| Section | Typical Line Items | What It Represents |
|---|---|---|
| Revenue (Sales) / Net Sales | Gross sales, sales returns & allowances, discounts | Total amount earned from core business activities before any expenses. |
| Cost of Goods Sold (COGS) | Direct material, direct labor, manufacturing overhead | The cost directly tied to producing the goods or services sold. |
| Gross Profit | Revenue – COGS | Profit after covering production costs; indicates efficiency of core operations. |
| Operating Expenses | • Selling, General & Administrative (SG&A) • Research & Development (R&D) • Depreciation & Amortization (if not included in COGS) |
Costs required to run the business that are not directly linked to production. |
| Operating Income (EBIT) | Gross Profit – Operating Expenses | Earnings before interest and taxes; measures profitability from core operations. |
| Non‑Operating Items | • Interest expense / interest income • Gains or losses on asset sales • Other miscellaneous income/expenses |
Items that arise from activities outside the primary business. |
| Income Before Taxes (EBT) | Operating Income ± Non‑Operating Items | Profit before the impact of income taxes. |
| Income Tax Expense | Current tax + deferred tax | Taxes owed on the period’s earnings. |
| Net Income | EBT – Income Tax Expense | Bottom‑line profit (or loss) attributable to shareholders. |
| Format | Description | When Used |
|---|---|---|
| Single‑Step | All revenues are grouped together, all expenses are grouped together; the difference is net income. | Simpler businesses, educational examples. |
| Multi‑Step | Separates operating from non‑operating items; highlights gross profit and operating income. | Most public‑company reports; provides more analytical detail. |
| Condensed | Summarized version for interim reports or brief disclosures. | Quarterly filings, management summaries. |
| Concept | Formula | Insight |
|---|---|---|
| Gross Margin | Gross Profit ÷ Revenue | Efficiency of production; higher = better cost control. |
| Operating Margin | Operating Income ÷ Revenue | Profitability of core operations before financing costs. |
| Net Profit Margin | Net Income ÷ Revenue | Overall profitability after all expenses and taxes. |
| Earnings Per Share (EPS) | Net Income ÷ Weighted‑average shares outstanding | Profit attributable to each common share; key metric for investors. |
| EBITDA | Operating Income + Depreciation + Amortization | Cash‑flow‑proximate measure, excludes non‑cash and financing effects. |
