The Profit & Loss Statement
Did You Make Money This Period?

What Is a Profit & Loss Statement?
The Profit and Loss Statement (P&L), also called an Income Statement, shows whether your business made or lost money over a specific time period. It answers the fundamental question: “Did we make money this month/quarter/year?”
P&L Structure: From Top to Bottom
A P&L statement reads from top to bottom, starting with revenue and working through various levels of profit until reaching the bottom line: Net Income.
Example Profit & Loss Statement
Here's an example profit and loss statement for a landscaping business, read directly from its accounting data so every column ties out:
| Income | |
| Design income | $14,329.28 |
| Discounts | ($850.00) |
| Landscaping Services | $205,963.36 |
| Services | $1,800.00 |
| Total Income | $221,242.64 |
| Cost of Goods Sold | |
| Cost of Goods Sold | $23,282.12 |
| Job Expenses | $60,118.87 |
| Total Cost of Goods Sold | $83,400.99 |
| Gross Profit | $137,841.65 |
| Expenses | |
| Advertising | $1,400.00 |
| Automobile | $4,214.35 |
| Bank Charges | $300.00 |
| Dues & Subscriptions | $450.00 |
| Insurance | $6,800.00 |
| Legal & Professional Fees | $2,000.00 |
| Office Expenses | $900.00 |
| Payroll Taxes | $6,583.02 |
| Rent or Lease | $8,700.00 |
| Repair & Maintenance | $1,250.00 |
| Supplies | $440.00 |
| Taxes & Licenses | $350.00 |
| Tools | $325.00 |
| Travel | $650.00 |
| Utilities | $1,740.00 |
| Total Expenses | $36,102.37 |
| Net Operating Income | $101,739.28 |
| Other Income | |
| Interest Earned | $55.89 |
| Other Income | $500.00 |
| Total Other Income | $555.89 |
| Other Expenses | |
| Depreciation | $17,085.00 |
| Interest Expense | $3,120.49 |
| Miscellaneous | $325.00 |
| Total Other Expenses | $20,530.49 |
| Net Income | $81,764.68 |
Profit and Loss Categories
A small business P&L groups its accounts into five standard categories, read in the same order. The account names inside each category differ from business to business; the categories do not. Here is where each line of the landscaping example above belongs:
| Category | What goes in it | Lines in the example | Example total |
|---|---|---|---|
| Income | Sales of your services or products, less discounts given | Landscaping Services, Design income, Services, Discounts | $221,242.64 |
| Cost of Goods Sold | Direct costs of doing the work: job labor and materials | Cost of Goods Sold, Job Expenses | $83,400.99 |
| Operating Expenses | Costs of running the business that are not tied to one job | Rent or Lease, Insurance, Payroll Taxes, Automobile, Legal & Professional Fees and ten smaller lines | $36,102.37 |
| Other Income | Income from outside the core business | Interest Earned, Other Income | $555.89 |
| Other Expenses | Costs outside core operations, such as depreciation and loan interest | Depreciation, Interest Expense, Miscellaneous | $20,530.49 |
Where a cost lands changes the margins you read. Job labor sits in Cost of Goods Sold for this service business because the crew's hours go straight into each job. Filed under operating expenses instead, the same dollars would make gross profit look larger than it is.
Monthly P&L vs Annual
The example covers a full year, January 1 to December 31, 2025. A monthly P&L uses the same categories for a single month. The two answer different questions:
- The annual P&L shows the whole year at once: full-year margins, the figures a tax return starts from, and the statement a lender or buyer usually asks for.
- The monthly P&L shows problems while there is still time to act on them: a cost that jumped, a margin that slipped, a slow month that needs cash set aside.
Averages hide the pattern. This business's income works out to about $18,400 a month ($221,242.64 over twelve months), but a seasonal business such as landscaping rarely earns the same amount every month. Compare each month with the same month last year, not only with the month before, so the season is not mistaken for a trend.
Key Profit Levels Explained
The P&L shows several profit levels, each telling you something different about your business:
Gross Profit shows how much money is left after paying for the direct costs of doing the work. In our example, $221,243 in revenue minus $83,401 in Cost of Goods Sold (the crew's job labor and materials) equals $137,842 Gross Profit. This represents a 62.3% gross margin.
Net Operating Income shows profit from core business operations. After deducting operating expenses like rent, insurance, utilities, and payroll taxes, this business generated $101,739 from its landscaping operations.
Net Income is the bottom line. It is total profit after everything, including depreciation and loan interest. This business earned $81,765 in true profit.

Key Ratios and Metrics
From our example P&L, here are the key metrics a business owner should track:
Understanding the Ratios
| Ratio | What It Tells You | Warning Signs |
|---|---|---|
| Gross Margin | Pricing power and direct cost control | Below industry average, declining trend |
| Operating Margin | Efficiency of operations | Below 10% for most businesses |
| Net Profit Margin | Overall profitability | Negative or below 5% |
| Labor Cost Ratio | Workforce efficiency | Increasing without revenue growth |
Cash vs. Accrual Basis
Your P&L can be prepared using two different accounting methods:
| Cash Basis | Accrual Basis |
|---|---|
| Revenue recorded when cash is received | Revenue recorded when earned (invoiced) |
| Expenses recorded when cash is paid | Expenses recorded when incurred |
| Simpler to understand | More accurate picture of profitability |
| Better for cash management | Required by GAAP for larger businesses |
| Common for small businesses | Better for decision-making |
P&L Analysis Checklist
Use this checklist when reviewing your P&L each month:
- Compare revenue to the same month last year. Is it growing?
- Check gross margin. Has it changed from last month?
- Review each expense category as a percentage of revenue
- Look for unusual or unexpected expenses
- Compare actual results to your budget
- Calculate year-to-date totals to see full picture
- Identify the top 3 expense categories to monitor
Advanced: Common-Size Analysis
A powerful technique is converting your P&L to percentages. This is called common-size analysis. Every line item is expressed as a percentage of total revenue.
Why it matters: Dollar amounts change as your business grows. Percentages reveal whether you're becoming more or less efficient over time.
Example: If labor costs were 25% of revenue last year and are 30% this year, that 5-point increase might represent $50,000+ in reduced profit, even if total revenue grew.
How the P&L Connects to Other Statements
The P&L doesn't exist in isolation:
- Net Income flows to the Balance Sheet. It increases Retained Earnings in the Equity section
- Net Income starts the Cash Flow Statement. Then adjustments show why profit differs from actual cash generated
- Revenue timing affects Accounts Receivable. If you're profitable but A/R is growing faster than revenue, investigate
The revenue and expense lines on your P&L are only as accurate as the chart of accounts they roll up from.
