How to Prepare an Income Statement: Step-by-Step Guide
Step 1: Determine the Reporting Period
Best Practice: Align your reporting period with your fiscal year and industry norms. Consistency is key for year-over-year comparisons.
Example: ABC Tech Inc. decides to prepare its income statement for the fiscal year ending December 31, 2023.

Example: ABC Tech Inc.’s revenue for 2023:
- Product sales: $500,000
- Consulting services: $200,000
- Interest income: $5,000
Total Revenue = $705,000
Step 3: Calculate Cost of Goods Sold (COGS)

COGS = Beginning Inventory + Purchases – Ending Inventory
Best Practice: Regularly conduct physical inventory counts to ensure accuracy.

- Beginning inventory: $50,000
- Purchases: $300,000
- Ending inventory: $75,000
COGS = $50,000 + $300,000 – $75,000 = $275,000
Step 4: Calculate Gross Profit
Subtract the Cost of Goods Sold from your Total Revenue to get your Gross Profit.
Gross Profit = Total Revenue – Cost of Goods Sold
Best Practice: Monitor your gross profit margin (Gross Profit / Total Revenue) over time to track pricing and cost management effectiveness.

Example: ABC Tech Inc.’s Gross Profit:
Gross Profit = $705,000 – $275,000 = $430,000
Gross Profit Margin = $430,000 / $705,000 = 61%
Step 5: List Operating Expenses
Next, list all operating expenses incurred during the period. These typically include:
- Salaries and wages
- Rent and utilities
- Office supplies
- Marketing and advertising
- Depreciation and amortization
- Insurance
- Any other business-related expenses
Best Practice: Use a consistent chart of accounts to categorize expenses for easy tracking and analysis.
Example: ABC Tech Inc.’s Operating Expenses:
- Salaries and wages: $200,000
- Rent and utilities: $50,000
- Marketing and advertising: $30,000
- Depreciation: $20,000
- Other expenses: $25,000
Total Operating Expenses = $325,000
Step 6: Calculate Operating Income
Subtract your Total Operating Expenses from your Gross Profit to get your Operating Income.
Operating Income = Gross Profit – Total Operating Expenses
Best Practice: Compare operating income to industry benchmarks to assess your operational efficiency.
Example: ABC Tech Inc.’s Operating Income:
Operating Income = $430,000 – $325,000 = $105,000
Step 7: Account for Other Income and Expenses
Include any other income or expenses not directly related to your core business operations, such as:
- Interest expense on loans
- Gains or losses from sale of assets
- One-time expenses or income
Best Practice: Clearly distinguish between recurring and non-recurring items for accurate future projections.
Example: ABC Tech Inc.’s Other Income and Expenses:
- Interest expense: $10,000
- Gain on sale of equipment: $5,000
Net Other Income/Expense = -$5,000
Step 8: Calculate Net Income
Finally, add or subtract these other income and expenses from your Operating Income to arrive at your Net Income.
Net Income = Operating Income + Other Income – Other Expenses
Best Practice: Calculate your net profit margin (Net Income / Total Revenue) to track overall profitability.
Example: ABC Tech Inc.’s Net Income:
Net Income = $105,000 – $5,000 = $100,000
Net Profit Margin = $100,000 / $705,000 = 14.2%
Step 9: Review and Format
Review your calculations for accuracy and format the income statement in a clear, easy-to-read manner. Typically, the income statement is presented in a top-down format, starting with revenue and ending with net income.
Best Practice: Use a consistent format across reporting periods and include prior period comparisons for context.
