For many small business owners, opening a Profit and Loss Statement (also called a P&L or Income Statement) can feel like reading a foreign language. Rows of numbers, unfamiliar terms, and accounting jargon often leave business owners wondering, “What am I actually supposed to be looking at?”

The good news is that you don’t need to be an accountant to understand one of the most important financial reports your business produces.

At BD Bookkeeping, we help business owners throughout the Greater St. Louis region and Southern Illinois understand their financial reports so they can make informed decisions with confidence. Here’s a simple guide to reading your Profit and Loss Statement without feeling overwhelmed.

What Is a Profit and Loss Statement?

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

Unlike a Balance Sheet—which provides a snapshot of your business at one point in time—a P&L tells the story of how your business performed during a month, quarter, or year.

Simply put, it answers one important question:

Did your business make money?

But there’s much more information hiding beneath that final number.

Revenue: Money Coming Into Your Business

The first section of a Profit and Loss Statement shows your revenue.

This includes income generated from:

  • Products sold
  • Services provided
  • Contract work
  • Other operating income

Ask yourself:

  • Is revenue increasing?
  • Are sales consistent from month to month?
  • Are seasonal trends affecting income?

Tracking revenue over time helps you identify growth opportunities and potential challenges.

Cost of Goods Sold (COGS)

If your business sells products or performs work requiring materials, you’ll likely see a section called Cost of Goods Sold (COGS).

These are the direct costs required to deliver your product or service, such as:

  • Materials
  • Inventory
  • Subcontractor labor
  • Manufacturing costs
  • Freight for products

Subtracting these costs from your revenue gives you your Gross Profit.

Gross Profit

Gross Profit tells you how much money remains after covering the direct costs of providing your products or services.

A healthy Gross Profit generally indicates that your pricing is appropriate and your direct costs are under control.

If Gross Profit begins shrinking, it could signal:

  • Rising material costs
  • Increased labor costs
  • Pricing that’s too low
  • Inefficient operations

Monitoring this number regularly helps you make proactive adjustments before profits decline further.

Operating Expenses

The next section includes the day-to-day costs of running your business.

Common operating expenses include:

  • Payroll
  • Rent
  • Utilities
  • Insurance
  • Marketing
  • Office supplies
  • Software subscriptions
  • Vehicle expenses
  • Professional services

These expenses are necessary to keep your business operating, but they should also be monitored carefully.

Even small increases across multiple expense categories can significantly impact profitability.

Net Profit: Your Bottom Line

After subtracting all expenses, you’ll arrive at your Net Profit (or Net Income).

This is commonly referred to as “the bottom line.”

Positive net profit means your business earned more than it spent.

Negative net profit means expenses exceeded revenue during the reporting period.

While one slow month isn’t necessarily cause for concern, consistently reviewing your net profit helps you identify trends and make better financial decisions.

Don’t Focus on Just One Month

One common mistake business owners make is judging performance based on a single month’s report.

Instead, compare:

  • Month-to-month performance
  • Quarterly trends
  • Year-over-year results

Looking at trends over time provides much more meaningful insight than isolated numbers.

Use Your P&L to Make Better Business Decisions

Your Profit and Loss Statement isn’t just a report for your accountant—it should serve as a decision-making tool.

A well-maintained P&L can help you answer questions like:

  • Should I raise my prices?
  • Can I afford another employee?
  • Which services are most profitable?
  • Are expenses growing too quickly?
  • Is my business becoming more profitable over time?

The more often you review your financial reports, the more confident you’ll become in using them.

Accurate Bookkeeping Creates Better Reports

Your Profit and Loss Statement is only as accurate as the bookkeeping behind it.

If transactions are miscategorized, accounts aren’t reconciled, or expenses are missing, your reports won’t reflect the true health of your business.

Consistent bookkeeping ensures your financial reports are:

  • Accurate
  • Timely
  • Easy to understand
  • Useful for decision-making

That’s why many business owners choose to partner with a professional bookkeeper.
