So, what exactly is an income statement? It’s also called a profit and loss statement, or simply a P& L. This document shows how much money your business made and spent during a certain time frame. At the end of the statement, you’ll find out if you made a profit or if you lost money.
Some other names for it include:
– Profit and loss statement
– Earnings report
– Business income report
Expert Opinion:
“The income statement is the heartbeat of a business. Without it, you’re flying blind when it comes to profitability.” — Janice Holland, CPA and Financial Educator
2. How to Prepare an Income Statement: Step-by-Step
Step 1: Choose Your Time Frame
First, decide if you want to make an income statement for a month, three months, or a whole year.
– Monthly: Great for new businesses or small companies wanting to keep an eye on short-term performance.
– Quarterly: Helps you notice seasonal patterns.
– Yearly: Needed for tax purposes and gives a view of long-term performance.
Step 2: Gather Your Financial Records
You need to pull together your:
– Sales data
– Receipts for expenses
– Payroll records
– Bank statements
It’s important that these records are accurate so your income statement reflects what truly happened.
Step 3: Calculate Total Revenue
This is the total money your business made from all its operations.
Formula:
Total Revenue = Sales Revenue + Other Income
Step 4: Subtract the Cost of Goods Sold (COGS)
These are the direct costs related to producing your goods or services.
Formula:
Gross Profit = Total Revenue – COGS
Step 5: Deduct Operating Expenses
Operating expenses are your regular costs. Think rent, employee salaries, utilities, and marketing.
Common operating expenses include:
– Salaries and wages
– Rent
– Marketing costs
– Equipment wear and tear
– Insurance
Step 6: Account for Other Income and Expenses
Include items like:
– Money made from investments
– Interest paid on loans
– Losses from selling assets
Step 7: Calculate Net Income
Finally, this is the money left over after all your expenses are taken out.
Formula:
Net Income = Gross Profit – Operating Expenses ± Other Income/Expenses
Expert Opinion:
“Your net income tells you more than profit—it reveals operational efficiency, expense management, and future potential.” — Luis Fernandez, CFO at FinVisor Inc.

– Revenues: The total amount of income you earn before any deductions. This is usually at the top of the income statement.
– Cost of Goods Sold (COGS): These are the direct costs tied to what you sell, and they help calculate gross profit.
Expert Opinion:
“COGS is a critical metric in product-based businesses. Keeping it low improves your margins significantly.” — Maria Chang, MBA, Financial Analyst
– Gross Profit: This is what you make after subtracting COGS from your revenue.
Formula:
Gross Profit = Revenue – COGS
– Operating Expenses: The ongoing costs that keep your business running.
– Net Income: This is what’s left after all costs have been deducted.
Formula Recap:
Net Income = Revenue – COGS – Operating Expenses ± Other Items

— Dana Lovell, Investment Analyst, MarketEdge
“For tax purposes, the income statement is your best friend. It offers a clear audit trail of how your money was made and spent.”
— Richard Moss, Tax Accountant at Moss & Associates
5. Common Mistakes to Watch Out For
1. Mixing Personal and Business Finances: Keep them separate to avoid confusion and maintain clear records.
2. Ignoring Depreciation: This can influence your costs and taxes.
3. Misclassifying Expenses: Proper labeling helps with understanding where your money goes.
4. Not Updating Regularly: An old income statement is useless for current decision-making.
