Your bookkeeper sends the month-end reports. You open the profit and loss statement and see revenue near the top, net income at the bottom, and a column of categories in between. Sales felt strong last month, yet the bottom line is lower than you expected, and you can’t tell why.
Many small business owners in Calgary are in this spot. They know the business well and they’re good at what they do, but nobody ever showed them how to read their financial statements. So the P&L gets a quick look at the last line and then sits in an inbox.
This guide explains how to read a profit and loss statement for a small business in Canada in plain language. It shows how each section connects to the next and gives you a short monthly routine for spotting trends. It also shows you what questions to bring to your accountant.
What a Profit and Loss Statement Shows (and What It Does Not)
A profit and loss statement, also called an income statement, summarizes what your business earned and what it spent to earn it over a set period. That period is usually a month, a quarter or a year.
It answers one main question: did the business make a profit during this period?
That question matters, but it’s narrower than many owners assume. A P&L does not tell you:
- How much cash you have. A profitable month can still leave your bank account tight if clients haven’t paid their invoices yet.
- What you own and owe. Loans, equipment, money owed to suppliers and GST you’ve collected but not yet remitted appear on the balance sheet, not the P&L.
- Whether the business is “healthy” overall. One statement is a snapshot of one period. It’s a starting point for questions, not a full diagnosis.
Business owners often get into trouble when they treat net income as money available to spend. Keep that distinction in mind as you read the rest of the statement.
The Five Lines That Matter Most
Most P&L statements follow the same basic flow from top to bottom. To make it concrete, here’s a simple example.
The following example is illustrative only. The business and figures are fictional and rounded for clarity.
Chinook Home Services is a small Calgary residential cleaning company with a team of six cleaners. Here’s its P&L for March:
| Line | Amount |
|---|---|
| Revenue | $40,000 |
| Cost of sales | $22,000 |
| Gross profit | $18,000 |
| Operating expenses | $10,000 |
| Net income (before tax) | $8,000 |
Revenue
Revenue, sometimes labelled sales or income, is what the business earned from its services during the period. For Chinook, that’s $40,000 of cleaning work.
If your business is registered for GST, revenue on the P&L should generally exclude the GST you charged clients. That GST isn’t yours. It’s collected on behalf of the CRA and sits as a liability until you remit it. If you’re unsure how that works, our GST guide for new Alberta corporations covers the basics.
Cost of Sales
Cost of sales, also called cost of goods sold or direct costs, covers the expenses tied directly to delivering your service. If you did less work, these costs would drop.
For Chinook, that’s mainly cleaner wages and cleaning supplies, totalling $22,000.
The real test is whether a cost rises and falls with the work. Office rent doesn’t change when you book three more jobs. Cleaner hours do.
Gross Profit and Gross Margin
Gross profit is revenue minus cost of sales. Chinook’s gross profit is $18,000.
Gross margin is the same figure as a percentage of revenue: $18,000 ÷ $40,000 = 45%. It tells you how much of each sales dollar is left after paying for the work itself.
Owners often ask what a “good” gross margin is. The honest answer is that it depends on your industry, pricing, staffing model and how your books are set up. A figure that works for one business may be a warning sign for another. For most owners, how your own margin changes over time is more useful than any outside benchmark.
Operating Expenses
Operating expenses, often called overhead, are the costs of running the business that don’t change much with each job. For Chinook, they might include:
- Office and storage rent: $2,000
- Administrative wages: $4,000
- Vehicle costs: $1,200
- Marketing: $1,500
- Software and subscriptions: $500
- Insurance: $400
- Professional fees: $400
Total operating expenses come to $10,000.
Net Income
Net income is gross profit minus operating expenses. Chinook shows $8,000 in net income before tax for March.
This is the “bottom line.” It’s important, but it makes the most sense when you understand every line above it.
Five Month-over-Month Questions to Ask
A single P&L tells you a little. Comparing it to previous months tells you much more. Good accounting software can show columns side by side, and setting that up once is worth the effort.
Here’s what Chinook’s April looked like next to March:
| Line | March | April |
|---|---|---|
| Revenue | $40,000 | $44,000 |
| Cost of sales | $22,000 | $26,400 |
| Gross profit | $18,000 | $17,600 |
| Gross margin | 45% | 40% |
| Operating expenses | $10,000 | $10,200 |
| Net income | $8,000 | $7,400 |
Revenue went up by $4,000, but net income went down. Five questions help explain a result like this.
1. Did revenue change, and do I know why?
An increase or drop should match what you saw on the ground: more clients, a price change, a seasonal shift or a large one-time job. If the number surprises you, that’s worth looking into before anything else.
2. Did gross margin hold steady?
This is often the most revealing question. Chinook’s margin fell from 45% to 40%. Possible causes include overtime, new staff still learning, a price discount, or jobs that took longer than quoted. Margin changes usually point to pricing or efficiency, and the P&L alone can’t tell you which.
3. Did any operating expense jump or appear for the first time?
Scan the overhead lines for anything that changed noticeably. A new software subscription, a one-time repair or a marketing push can all be reasonable. The point is to know why the number moved.
4. Is net income moving with revenue, or against it?
When revenue rises and profit falls, as it did for Chinook, the business may be growing in a way that costs more than it earns. That’s not automatically a problem, but it’s a strong signal to dig deeper.
5. Does anything look wrong, not just different?
Sometimes a number changes because the books changed, not the business. That leads to the next section.
Common Distortions That Make a P&L Misleading
Accountants often see P&L statements that tell a misleading story because of how transactions were recorded. Before drawing conclusions, check for these.
Owner and Personal Items
Personal purchases run through the business account can inflate expenses. On the other hand, some owner-related amounts shouldn’t appear as expenses at all. For a corporation, dividends paid to shareholders are not an operating expense, though a salary paid to an owner generally is. For a sole proprietor, money you take out for yourself is a draw, not an expense.
When these get mixed together, profit can look much better or much worse than it really is.
Timing
If your books are kept on a cash basis, or bills aren’t entered in the right period, one month can look unusually strong and the next unusually weak. A few common examples:
- An annual insurance premium recorded entirely in one month
- A large invoice sent late, pushing revenue into the following month
- Supplier bills entered in a batch whenever someone gets to them
Spreading these costs across the right periods, or at least knowing they’re there, gives you a more accurate picture.
Miscoding
A cleaning supply purchase coded as office expense moves money from cost of sales into overhead. That inflates your gross margin and hides a real cost of delivering the service. Small coding errors add up, and they’re one of the areas where small mistakes create bigger problems later. Our article on bookkeeping mistakes Calgary entrepreneurs make covers several of these in more detail.
Items That Don’t Belong on the P&L
A few transactions regularly land in the wrong place:
- Loan principal payments. Only the interest portion is generally an expense. The principal reduces a liability on the balance sheet.
- Large equipment purchases. A new vehicle or major piece of equipment is usually recorded as an asset and expensed gradually through amortization (depreciation), rather than all at once.
- GST remittances. As noted above, these relate to a liability, not an expense.
When to Look at the Balance Sheet and Cash Flow Too
The P&L works best as one of three statements read together.
Look at the balance sheet when you want to know what the business owns and owes. It shows how much clients owe you, what you owe suppliers and lenders, how much GST you’re holding, and the owner’s equity in the business. If net income looks strong but debt or unpaid client invoices keep growing, the balance sheet will show it.
Look at cash flow when profit and your bank balance don’t seem to match. A cash flow statement or a simple cash forecast shows where money actually came from and went. That includes slow-paying clients, loan payments and equipment purchases that don’t fully appear on the P&L.
As a general rule, bring all three to the table when you’re making a bigger decision: hiring, taking on financing, buying equipment, or planning around year-end and tax. The P&L alone isn’t enough to support lending, investment or tax decisions, and an accountant can help you read it alongside the rest of your financial picture.
A Simple Monthly P&L Routine
You don’t need hours each month. A focused 20 to 30 minutes is often enough:
- Confirm the books are current. Bank and credit card accounts should be reconciled for the month. Our bookkeeping checklist for new Calgary businesses is a helpful reference.
- Pull a side-by-side comparison of this month, last month and the same month last year if you have it.
- Work through the five questions above and jot down anything you can’t explain.
- Check for distortions such as owner items, timing issues and miscoding.
- Bring your list to your accountant or bookkeeper rather than guessing.
Doing this regularly turns the P&L from a report you skim into a tool you actually use. It fits well with the other habits we describe in 5 smart accounting habits every Calgary business owner should know.
