What Is a Profit and Loss Statement? Its Importance and Examples for FY26

A profit and loss statement (P&L), also called an income statement, shows your business’s revenue, costs, and net profit or loss over a set period. It is one of the core financial statements used to track profitability, support tax preparation, and assess business performance.

However, many small business owners have never made or analysed a profit and loss statement before, and approaching one for the first time can be confusing,, especially if you’re not using an accounting software platform to track all of your financial data. In this guide, we’ll explain what a profit and loss statement is, how to read one and show you how to create your own.

What Is a Profit and Loss Statement?

A profit and loss statement is a financial document that breaks down your business’s net income over a set period of time. It shows key financial metrics like your revenue, cost of goods sold, and operating expenses.

Many businesses choose to prepare a profit and loss statement monthly, quarterly, or annually since it makes it easy to monitor changes to your business’s profitability over time.

You may hear profit and loss statements referred to by several different names. They’re also called income statements, P&L statements, earning statements, statements of profit, or statements of operations.

Profit and loss statement example

The best way to understand how profit and loss statements work is with an example. Here’s a simple P&L statement for a small business.

Gross profit is defined as your revenue minus your cost of goods sold—that is, the cost of any raw materials or labour that went into producing and delivering your products. Operating profit is your gross profit minus all of your business’ operating expenses. Your net profit is your operating profit minus any interest you pay on debt and any taxes your business pays.

Your profit and loss statement can be as detailed as you need. For example, you can break down revenue to show income from different product lines, business locations, or even specific customers. You can also break down operating expenses into categories like advertising, office supplies, travel, payroll, and insurance. These breakdowns are very important for analysing your P&L statement and drawing insights about your business.

How To Analyse a Profit and Loss Statement

Use your P&L to answer three questions fast: Are sales growing? Are costs under control? Is profit improving? This all matters because it allows a business to show a paper profit but still have cash flow problems if customers pay late.

What to check first

• Revenue (top line)
• COGS (direct costs)
• Gross profit
• Operating expenses
• Net profit (bottom line)

How to analyse P&L quickly

• Compare periods: month-on-month, quarter-on-quarter, year-on-year.
• Check margins:
  • Gross margin = Gross profit ÷ Revenue
  • Net margin = Net profit ÷ Revenue
• Convert costs to % of revenue (common-size analysis) to see whether costs are rising faster than sales.
• Spot unusual changes: spikes in payroll, marketing, rent, software, etc.
• Review with other statements: use your cash flow statement and balance sheet alongside the P&L for a full picture.

Why Do You Need a Profit and Loss Statement?

A P&L helps you track performance, prepare for taxes, and prove financial health to lenders or investors.

Main reasons to use one:

• Track profitability: See whether your business is making money and what is driving changes.
• Make better decisions: Spot rising costs, weak margins, or underperforming products/services.
• Support tax preparation: A P&L organises much of the same income and expense data you’ll need for tax reporting.
• Apply for funding: Banks and investors often ask for P&L statements to assess risk and performance.
• Plan growth: Useful for budgeting, hiring, pricing, and expansion decisions.

How To Make Your Own Profit and Loss Statement

You can create a P&L in accounting software, Excel, or a template. The key is using accurate figures and consistent categories.

1) Choose a reporting period

Pick the date range:

• Monthly
• Quarterly
• Annually

2) Choose your accounting method

Use one method consistently:

• Cash basis: record income/expenses when money moves
• Accrual basis: record income/expenses when earned/incurred

3) Add up revenue

Include all income for the period, such as:

• Sales
• Services
• Other income (e.g. interest)

4) Calculate COGS

Add direct costs linked to what you sold (materials, stock, direct labour).

Gross profit = Revenue − COGS

5) Add operating expenses

List overheads like:

• Payroll (non-direct labour)
• Rent and utilities
• Insurance
• Marketing
• Software
• Travel

Operating profit = Gross profit − Operating expenses

6) Subtract interest and taxes

Add interest and tax lines (if included in your format).

Net profit (or loss) = Operating profit − Interest − Taxes

7) Review and save

Before sharing or using it:

• Check totals
• Check categories are consistent
• Avoid double-counting (especially COGS vs expenses)

Common P&L Mistakes to Avoid

These mistakes make a P&L look accurate while hiding real problems.

• Mixing personal and business expenses: Use a separate business account.
• Double-counting costs: Don’t record the same cost in both COGS and operating expenses.
• Inconsistent categories: Keep category names and rules the same across periods.
• Focusing only on revenue: Revenue can rise while profit falls. Check margins too.
• Confusing profit with cash: A profitable month does not always mean cash is available.
• Missing small recurring costs: Subscriptions and software charges add up over time.
• Only reviewing the P&L once a year: Review monthly or quarterly to catch issues early.
