How to Read a Profit and Loss Statement

A Profit and Loss statement (also called an income statement or P&L) summarises your business's revenue, expenses, and profit over a specific period. It is the single most important financial report for understanding how your Calgary business is actually performing.

The Basic Structure

A P&L has three main sections:

• Revenue (top line): All income your business earned during the period — sales, service fees, commissions, etc.
• Expenses: All costs incurred to operate the business — rent, wages, supplies, marketing, insurance, etc.
• Net Profit (bottom line): Revenue minus expenses. This is what your business actually earned (or lost).

Key Line Items to Watch

Gross Profit is your revenue minus the direct cost of goods or services sold (COGS). This tells you how much money you make before overhead. If gross profit is shrinking, your pricing or direct costs need attention.

Operating Expenses are the ongoing costs of running the business that aren't directly tied to producing your product or service — rent, utilities, office supplies, marketing, and insurance. These should be relatively stable month to month.

Net Profit is what remains after all expenses. This is the truest measure of your business's financial health. A positive net profit means you're making money; a negative number means you're losing it.

Percentages Matter More Than Dollars

Smart business owners look at each expense category as a percentage of revenue. If your rent is 15% of revenue and industry average is 10%, that's a red flag. Percentages also let you compare performance across months and years regardless of revenue changes.

Monthly Comparison Is Key

A single month's P&L tells you something, but comparing month-over-month and year-over-year tells you much more. Look for trends: Is revenue growing? Are certain expense categories creeping up? Is your profit margin improving or declining?
