Profit is what’s left after you subtract your costs from your revenue. The basic formula is simple: Revenue minus Expenses equals Profit. But in practice, there are three distinct levels of profit, each telling you something different about how a business is performing. Knowing which costs to subtract at each stage is the key to finding profit accurately.
The Three Levels of Profit
An income statement calculates profit in stages, like walking down a staircase. You start with total revenue at the top and subtract different categories of costs as you move down. Each subtraction gives you a different profit figure.
Gross profit is the first stop. It tells you how much money is left after covering only the direct costs of producing what you sell. The formula is:
Gross Profit = Revenue − Cost of Goods Sold (COGS)
Operating profit goes one step further by subtracting the overhead costs of running the business, things like rent, office salaries, marketing, and insurance. The formula is:
Operating Profit = Gross Profit − Operating Expenses
Net profit is the final number, sometimes called the bottom line. It’s what remains after you also account for interest payments and income taxes. Net profit reflects the true earnings a business keeps.
Net Profit = Operating Profit − Interest − Taxes
Which Costs Go Where
The trickiest part of finding profit is categorizing your costs correctly. A useful test: ask yourself whether a particular expense would still exist even if you made zero sales. If the answer is yes, it’s an operating expense, not a cost of goods sold.
Cost of goods sold (COGS) includes everything directly tied to producing or delivering your product. For a coffee shop, that means the beans, cups, lids, filters, and water. For a retailer, it’s the wholesale price paid for merchandise. For a manufacturer, it includes raw materials and the wages of assembly-line workers.
Operating expenses cover the costs of keeping the business running regardless of how much you sell. Common examples include:
- Rent for office or retail space
- Utilities like electricity and internet
- Administrative payroll for accountants, marketing staff, and office managers
- Insurance premiums
- Office supplies and legal costs
- Depreciation on equipment and property
The same type of expense can land in different categories depending on its role. Payroll for a factory worker building products is COGS. Payroll for an accountant tracking the books is an operating expense. Getting this distinction right is what makes your gross profit and operating profit figures meaningful.
A Step-by-Step Example
Suppose you run an online store that sold $200,000 worth of products last year. Here’s how you’d walk through the profit calculation:
First, add up your cost of goods sold. You paid $80,000 for wholesale inventory and $10,000 for shipping materials. Your COGS totals $90,000.
Gross Profit = $200,000 − $90,000 = $110,000
Next, tally your operating expenses. You spent $24,000 on rent, $18,000 on employee salaries (non-production), $12,000 on marketing, and $6,000 on software and office supplies. That’s $60,000 in operating expenses.
Operating Profit = $110,000 − $60,000 = $50,000
Finally, you paid $3,000 in interest on a business loan and $9,400 in income taxes.
Net Profit = $50,000 − $3,000 − $9,400 = $37,600
That $37,600 is the actual money the business earned for the year after every cost is accounted for.
How to Find Profit on a Financial Statement
If you’re reading a company’s income statement rather than building your own, the structure follows the same staircase. The top line shows total revenue (sometimes called gross revenue or sales). Below that, you’ll see a deduction for returns and allowances, leaving you with net revenue.
The next major line item is cost of goods sold. Subtract that from net revenue and you get gross profit, which is usually labeled on its own line. Below gross profit, you’ll see operating expenses broken into categories like selling, general, and administrative expenses (often abbreviated SG&A) and depreciation. After those deductions, you reach operating profit, sometimes labeled “income from operations.”
Further down, interest income is added and interest expense is subtracted. After income tax is deducted, you arrive at net profit (also called net income or net earnings). Public companies are required to report these figures, so if you’re researching a stock, the income statement in a company’s annual filing will lay out each profit level clearly.
Profit Margins Tell You More Than Profit Alone
A raw profit number doesn’t tell you much without context. A business earning $50,000 in net profit on $200,000 in revenue is performing very differently from one earning $50,000 on $5 million in revenue. That’s where profit margin comes in.
Profit margin converts your profit into a percentage of revenue:
Net Profit Margin = (Net Profit ÷ Revenue) × 100
In the first example above, the net profit margin would be ($37,600 ÷ $200,000) × 100 = 18.8%. You can calculate a margin at any profit level. Gross margin, operating margin, and net margin each reveal how efficiently a business handles different types of costs.
What counts as a “good” margin varies enormously by industry. Service-based businesses with low production costs, like consulting firms or software companies, can see net margins well above 20%. Retailers and restaurants, where COGS eats a large share of revenue, often operate on single-digit net margins. Comparing your margin to industry averages is more useful than targeting an arbitrary number.
Why Profit Isn’t the Same as Cash
One important distinction that trips up many business owners: showing a profit on paper doesn’t necessarily mean you have cash in the bank. Profit measures revenue minus expenses over a period, but it doesn’t account for the timing of when money actually moves in and out.
For example, you might record a $10,000 sale in March, but your customer doesn’t pay you until June. Your income statement shows $10,000 in revenue for March, but your bank account won’t reflect it for months. Meanwhile, you still need to pay suppliers, employees, and rent on time. This is why a profitable business can still run into serious cash problems. Tracking cash flow alongside profit gives you the full picture of your financial health.
Tracking Profit Over Time
Finding profit once is useful. Finding it consistently, month after month, is what actually helps you make better decisions. Set up a simple system where you record revenue and categorize every expense as either COGS or an operating expense. Even a basic spreadsheet works for a small business or freelance operation.
Compare your profit figures across months and quarters to spot trends. If gross profit is shrinking while revenue stays flat, your production costs are climbing. If operating profit drops while gross profit holds steady, your overhead is growing faster than your sales. Each profit level acts as a diagnostic tool, pointing you toward the specific area of your finances that needs attention.
