What Is a Profit and Loss Statement?
A profit and loss statement (also called a P&L or income statement) is a report that shows how much money your business earned, how much it spent, and what’s left over during a specific period — usually a month, quarter, or year.
It answers the most fundamental question in business: are you making money or losing it?
The Key Sections
A P&L flows from top to bottom, and each section builds on the one above it:
1. Revenue (Top Line)
This is the total money your business earned from selling products or services. It’s called the “top line” because it sits at the top of the report.
If you sold $50,000 worth of design services in a quarter, that’s your revenue.
2. Cost of Goods Sold (COGS)
These are the direct costs of delivering what you sell. For a product business, it’s materials and manufacturing. For a service business, it might be subcontractor costs or direct labour.
3. Gross Profit
Revenue minus COGS equals gross profit. This tells you how much money you make before accounting for overhead.
$50,000 revenue - $15,000 COGS = $35,000 gross profit
Your gross margin (gross profit as a percentage of revenue) is a critical number. In this example, it’s 70%.
4. Operating Expenses
These are the costs of running your business that aren’t directly tied to delivering your product or service:
- Rent and utilities
- Salaries (non-production staff)
- Marketing and advertising
- Software and subscriptions
- Insurance
- Professional fees
5. Operating Profit
Gross profit minus operating expenses. This shows how much your core business operations generate.
$35,000 gross profit - $20,000 operating expenses = $15,000 operating profit
6. Net Profit (Bottom Line)
After accounting for any other income (like interest) and other expenses (like taxes and loan interest), you arrive at net profit — the actual money your business kept.
This is the “bottom line” — the number that tells you whether your business is truly profitable.
How to Use Your P&L
Compare Periods
Look at your P&L month over month or year over year. Is revenue growing? Are expenses creeping up? Trends tell you more than a single snapshot.
Watch Your Margins
If your gross margin is shrinking, you’re either charging too little or your direct costs are rising. Either way, it needs attention.
Find the Leaks
A P&L makes it easy to spot expense categories that are growing faster than your revenue. That marketing spend that doubled last quarter — is it actually driving more sales?
Make Informed Decisions
Thinking about hiring someone? Your P&L shows whether you can afford it. Considering a price increase? Your margins will tell you if it’s necessary.
Share With Stakeholders
Banks, investors, and partners will ask for your P&L. It’s the standard way to demonstrate your business’s financial performance.
A Simple Habit
Review your P&L at least monthly. It takes five minutes and gives you a clear picture of where your business stands. In Fastbooks, your P&L is always up to date and available with a single click — no waiting for your accountant to prepare it.
