How to Read a Profit and Loss Statement
"My accountant sends me this report every month. I nod. I file it. I have no idea what I'm looking at." — We hear this constantly. Let's fix it.
The Profit and Loss statement (also called an Income Statement) is the most important financial document your business produces. It answers one question: did your business make or lose money in this period?
But knowing you made $40,000 in net profit is one thing. Understanding why, and what you should do about it, is another. That's what this guide is for.

The 4 Numbers That Actually Matter
💰
Gross Profit Margin
Gross Profit ÷ Revenue × 100. This tells you how efficient your core business is. A low margin means your product or service is too expensive to deliver.
Target: 50-70% for service businesses
📉
Operating Expense Ratio
Operating Expenses ÷ Revenue × 100. If this is creeping up month over month, your overhead is growing faster than your revenue. Red flag.
Watch for upward trends
🏦
Net Profit Margin
Net Profit ÷ Revenue × 100. The ultimate efficiency number. How many cents of every dollar you keep after all costs. Below 10% and you're running thin.
Target: 10-20% for small businesses

Month-over-Month Trend
A single P&L is a snapshot. Three months compared side by side is a trend. A trend tells you if things are improving or quietly getting worse.

Warning Signs in Your P&L
Revenue growing but profit shrinking — your costs are growing faster than your sales. Find what's leaking.
COGS above 60% for a service business — your delivery costs are too high. Review pricing or efficiency.
One line item dominating expenses — if a single cost is over 30% of your operating expenses, you are dependent on that vendor or employee.
Net profit positive but bank account empty — this means cash flow timing issues. You have profitable sales but customers aren't paying fast enough.
Your P&L Should Tell You a Story.
