How to Read Your P&L in Five Minutes

What's a P&L, Really?

A P&L (profit and loss statement) is just a scoreboard for your business over a specific time period — usually a month or a year. It shows how much money came in (revenue), how much went out (expenses), and what you're left with (profit or loss). That's it.

The Big Three Sections

1. Revenue (aka "The Money In")

This is all the income your business earned. It's usually broken down by source — product sales, service fees, affiliate income, whatever applies to you. Don't overthink it: revenue is what your customers paid you.

2. Cost of Goods Sold (COGS)

These are the direct costs to deliver what you sell. For a product-based business, it's materials and manufacturing. For a service business, it might be subcontractor fees or software subscriptions tied to delivering your service. This is NOT overhead — it's the stuff that scales with your sales.

3. Operating Expenses

Everything else: rent, salaries, insurance, marketing, utilities. These are the costs of running your business that don't directly tie to each individual sale. This section is often where business owners make their big discoveries — you might realize you're spending way more on some categories than you thought.

The Numbers You Actually Care About

Most P&Ls show three profit numbers:

• Gross profit: Revenue minus COGS. Shows how much margin you have on what you actually sell.
• Operating profit: Gross profit minus operating expenses. This is your business's efficiency at running itself.
• Net profit: The final line. Money left after everything. This is what actually matters for taxes and your wallet.

One Simple Question to Ask Every Month

When you look at your P&L, ask: "Did I make more or less money this month than last month, and why?" If revenue is down, dig into which income streams dropped. If expenses are up, find out where the spike came from. Most P&L problems are easy to solve once you see them clearly.

Pro Tips for Small Business Owners

1. Look at your P&L every month, not just at year-end. Monthly checks let you catch problems while there's still time to fix them.
2. Compare your P&L month-to-month and year-to-year. Trends matter more than one number in isolation.
3. Ask your bookkeeper or accountant to flag anything unusual. If a line item suddenly doubled, there's usually a reason.
