How to Read a Profit & Loss Statement | Small Business Guide

Not sure how to read your Profit & Loss statement? Learn what revenue, expenses, and net profit tell you about your small business and how to use your P&L to make better financial decisions.

Your Profit & Loss statement may be one of the most important financial reports in your business.

But if you only look at it during tax season—or immediately scroll to the bottom to see whether you made a profit—you’re missing much of what this report can tell you.

A Profit & Loss statement, often called a P&L or income statement, shows how your business performed financially over a specific period of time.

More importantly, it can help you answer questions like:

• Is my revenue growing?
• Are my expenses increasing too quickly?
• Which areas of my business are most profitable?
• Am I actually making money?
• Are there trends I need to address?

You don’t need to be an accountant to understand your P&L. You just need to know what you’re looking at.

What Is a Profit & Loss Statement?

A Profit & Loss statement summarizes your business’s income and expenses over a specific period of time.

You might review a P&L for:

• One month
• One quarter
• Year-to-date
• An entire year

At its simplest, the report follows this basic formula:

Revenue – Expenses = Profit or Loss

But each section of the report tells you something different about your business.

Revenue: What Your Business Earned

The top section of your P&L typically shows your revenue or income.

Depending on your business, revenue may be separated by service, product, location, program, or another category.

Don’t just look at the total.

Ask:

• Is revenue increasing or decreasing?
• Which services generate the most revenue?
• Are there seasonal patterns?
• How does this period compare with last year?
• Are we on track to meet our annual goal?

Revenue is an important measurement of growth, but revenue alone doesn’t tell you whether your business is financially healthy.

That’s where the rest of the P&L becomes important.

Cost of Goods Sold: What It Costs to Deliver Your Product or Service

Some businesses have a section called Cost of Goods Sold, or COGS.

These are costs directly related to producing the products or services you sell.

Depending on your business, this could include:

• Materials
• Inventory
• Direct labor
• Subcontractors
• Shipping or production costs

Subtracting these costs from revenue gives you your gross profit.

Gross Profit: What Remains Before Operating Expenses

Gross profit shows how much money remains after paying the direct costs associated with generating your revenue.

This number can be particularly useful when evaluating pricing.

For example, your revenue may be increasing, but if the cost of delivering your services is increasing even faster, your gross profit margin may be shrinking.

More sales don’t automatically mean more profit.

Operating Expenses: What It Costs to Run the Business

Next, you’ll typically see your operating expenses.

These may include:

• Rent
• Insurance
• Payroll
• Marketing
• Software subscriptions
• Professional fees
• Office expenses
• Utilities

This section deserves more than a quick glance.

Compare expenses from month to month and year to year.

Are certain costs gradually increasing?

Are you paying for subscriptions you no longer use?

Did an expense suddenly jump?

Understanding where your money is going can help you identify opportunities to improve profitability without necessarily increasing revenue.

Net Profit: What Did the Business Actually Earn?

Near the bottom of your P&L, you’ll find your net income or net profit.

This is what’s left after the expenses shown on the P&L are deducted from revenue.

If the number is positive, your business generated a profit during that period.

If it’s negative, your business experienced a loss.

But don’t evaluate this number in isolation.

One unusual expense could make a profitable business show a loss for a particular month. Seasonal businesses may naturally have profitable and unprofitable periods.

The trend over time often tells you more than a single month’s result.

Profit Doesn’t Mean Cash

Here’s where many business owners get confused.

Your P&L says you made $20,000.

So why isn’t there an extra $20,000 sitting in the bank?

Because profit and cash flow aren’t the same thing.

Loan principal payments, owner draws or distributions, equipment purchases, accounts receivable, and other balance sheet activity can affect your bank balance without appearing as ordinary expenses on your P&L.

That’s why your Profit & Loss statement shouldn’t be reviewed by itself.

It is one piece of your overall financial picture.

Don’t Just Look at the Bottom Line

One of the most common mistakes business owners make is opening the P&L, scrolling directly to net income, and closing the report.

Instead, look at the story behind that number.

Imagine two businesses both report $100,000 in revenue.

Business A earns $25,000 in profit.

Business B earns $5,000.

The revenue is identical, but their financial performance is very different.

Understanding why is where your P&L becomes valuable.

Compare Your P&L Over Time

A single P&L gives you information.

Comparative P&Ls give you insight.

Consider comparing:

• This month to last month
• This quarter to the previous quarter
• This year to last year
• Actual results to your budget

These comparisons help you identify trends that may otherwise be easy to miss.

A small expense increase may not seem significant during one month. If that expense has increased every month for six months, however, it’s worth investigating.

How Often Should You Review Your P&L?

For most small businesses, reviewing the Profit & Loss statement monthly is a good starting point.

You don’t need to spend hours analyzing it.

Instead, develop a habit of asking a few consistent questions:

• Is revenue where I expected it to be?
• Are any expenses unusually high?
• Is my profit margin changing?
• Is anything significantly different from last month or last year?
• Is there something here I need to investigate?

A regular monthly review helps you catch changes while there’s still time to respond.

Your P&L Should Help You Run Your Business

Your Profit & Loss statement isn’t simply something your accountant needs at tax time.

It’s a management tool.

When your bookkeeping is accurate and you understand how to read your P&L, you can use it to make better decisions about pricing, spending, hiring, growth, and profitability.

The goal isn’t to become an accountant.

It’s to understand your business well enough to know what your numbers are telling you.
