What is a profit and loss statement?

A profit and loss statement is a financial report that shows how much your business earned and spent over a set period. The difference tells you whether you made a profit or a loss.

You’ll also hear it called an income statement. It can cover a single month or a full financial year, depending on what you need.

Picture a café owner who’s busy every weekend but still short of money at month end. A P&L shows whether the cause is thin margins on each coffee or overheads such as rent eating into the takings.

Reviewing your P&L regularly helps you catch changes in sales early and respond before they affect your bottom line. It’s one of the core reports in small business accounting, and it’s the one you’ll check most often.

What does a profit and loss statement include?

A P&L groups your figures into a handful of line items, and each one builds on the line before. Most P&L statements include:

revenue, which is the money you earn from sales before any costs come out
cost of goods sold (COGS), which is the direct cost of making or buying what you sell, such as coffee beans or wholesale stock
gross profit, which is revenue minus COGS
operating expenses, which are the day-to-day costs of running the business, such as rent and salaries
non-operating items, which are income and costs outside your main activity, such as interest on a loan
net profit or net loss, which is what’s left after every expense, including interest and tax

Expenses also split into fixed and variable costs. Fixed costs such as rent stay the same each month, while variable costs such as ingredients rise and fall with your sales.

Profit and loss statement formulas

Every figure on a P&L comes from a simple formula, so you can check any line yourself. These are the ones you’ll use most:

gross profit = revenue minus COGS
operating profit = gross profit minus operating expenses
profit before tax = operating profit plus non-operating income, minus non-operating expenses such as interest
net profit = profit before tax minus income tax
gross profit margin = gross profit divided by revenue, multiplied by 100
net profit margin = net profit divided by revenue, multiplied by 100

Margins turn raw figures into percentages, so you can compare a quiet month with a busy one. A net profit margin calculator gives you the answer in seconds.

How to read a profit and loss statement

Read a P&L from the top down, starting with revenue and finishing at net profit. Each line tells you something different about how the business is performing.

Gross profit shows how efficiently you produce or source what you sell. If your gross profit is RM60,000 on revenue of RM150,000, your gross profit margin is 40%. A falling margin can point to rising supplier costs or prices set too low.

Operating profit shows whether your core business makes money before interest and tax. Net profit is the final result, and your net profit margin shows how much of every ringgit of revenue you keep.

Compare each period with the last one, or with the same month last year, to see which lines are moving. Then express each line as a percentage of revenue, so a rent increase stands out even when sales grow.

These comparisons are the basis of profitability ratios, which help you track performance over time.

How to prepare a profit and loss statement

You can prepare a P&L in six steps once your bookkeeping is up to date. Work through them in order, because each step uses the figure from the one before.

Choose your reporting period. Pick the dates you want to cover, then record your transactions for that period so nothing is missing.
Add up your revenue. Total your sales for the period, and keep non-operating income such as interest earned separate.
Calculate your cost of goods sold. Add up the direct costs of the goods or services you sold in the period.
Work out your gross profit. Subtract COGS from revenue.
List your operating expenses. Group the costs of running the business, such as rent and wages, into clear categories.
Calculate your net profit or net loss. Subtract operating expenses from gross profit, adjust for non-operating items, then deduct tax.

Before you finalise the figures, run a trial balance to confirm your debits and credits match. It catches missing or doubled entries before they reach your P&L.

Accounting software can produce a P&L automatically from the transactions you’ve already recorded. If you’d rather use a spreadsheet, a free profit and loss template gives you the layout. An accountant or bookkeeper can also prepare it and check your categories.

Profit and loss statement example

A worked example makes the formulas easier to follow. Here’s a simplified P&L for Kopi Kita, a fictional café in Petaling Jaya, for the quarter ending 30 June 2026:

revenue from drinks and food: RM150,000
cost of goods sold (coffee beans, milk and baking ingredients): RM54,000
gross profit: RM96,000
operating expenses (rent, staff wages, utilities and marketing): RM72,000
operating profit: RM24,000
interest on a business loan: RM1,500
profit before tax: RM22,500
income tax (estimated): RM4,500
net profit: RM18,000

Kopi Kita’s gross profit margin is 64% (RM96,000 divided by RM150,000), and its net profit margin is 12% (RM18,000 divided by RM150,000). If ingredient prices climb next quarter, the owner will see the gross margin slip first.

Single-step vs multi-step profit and loss statements

There are two common P&L formats, and the right one depends on how much detail you need. Both reach the same net profit figure.

A single-step P&L adds up all revenue and subtracts all expenses in one calculation. It suits sole proprietors and very small businesses with simple finances.

A multi-step P&L sorts income and expenses into operating and non-operating groups, as the Corporate Finance Institute explains. That split puts gross profit and operating profit on their own lines, so you can see how your core business performs before interest and tax. The Kopi Kita example above uses this format.

Why a profit and loss statement matters for your business

Your P&L is the clearest record of whether your business model works. You can use it to:

set prices that cover your costs and leave a healthy margin
spot rising costs early, before they eat into profit
decide which products or services to grow and which to drop
support a loan application with a record of past profits
estimate your tax before filing deadlines arrive

Each of these decisions depends on figures you can trust. That’s why the mistakes below are worth checking for every time.

Common profit and loss statement mistakes

Small errors on a P&L can lead to big decisions based on the wrong numbers. Watch for these common slips:

mixing personal and business spending, which distorts your expenses and your profit
putting costs in the wrong category, such as recording ingredients as an operating expense instead of COGS
treating cash received as revenue earned, which makes some months look better or worse than they were
reviewing one period in isolation, which hides seasonal patterns and slow trends
leaving out non-cash costs such as depreciation, which overstates your profit

Keeping profit and cash apart in your records is a big part of managing cash flow well.

How a profit and loss statement differs from a balance sheet

A P&L and a balance sheet answer different questions about your business. Together they give you a fuller picture.

Think of your P&L as a video of the period and your balance sheet as a photo taken on its last day. The P&L shows what you earned and spent, while the balance sheet shows what you own, what you owe and the owner’s equity.

The two financial statements are linked, because your net profit or loss flows into the equity section of the balance sheet. A third report, the cash flow statement, tracks how cash moved in and out over the same period.

If you use accrual accounting, your P&L records sales when you make them and expenses when you incur them, even if cash moves later. That’s how a profitable quarter can still leave your bank balance low.

Profit and loss statements in Malaysia

If you run a business in Malaysia, your reporting duties depend on how the business is set up. Here’s what applies to companies and sole proprietors, plus the record-keeping and e-Invoice rules.

Private limited companies (Sdn Bhd)

Private limited companies report under the Companies Act 2016, which the Companies Commission of Malaysia (SSM) administers. Under SSM’s practice directive, a Sdn Bhd circulates its financial statements to members within six months of year end, then lodges them within 30 days.

The Malaysian Accounting Standards Board lets private companies report under the Malaysian Private Entities Reporting Standard (MPERS) or the full Malaysian Financial Reporting Standards (MFRS).

Your P&L figures are also the starting point for your company’s tax return. You file Form C with the Inland Revenue Board of Malaysia (LHDN) electronically within seven months of the close of your accounts.

Sole proprietors

As a sole proprietor, you report your business results on your personal tax return. Form B is the return for individuals with business income, and you file it by 30 June of the following year.

Record keeping and e-Invoicing

Two more rules affect how you keep the records behind your P&L. Malaysian company and tax law generally require you to keep business records for seven years.

LHDN’s e-Invoice guideline currently exempts businesses with annual turnover or revenue under RM3 million. The exemption doesn’t apply if a non-individual shareholder, holding company, related company or joint venture has turnover of RM3 million or more. Check LHDN’s latest guidance before you rely on this threshold.

FAQs on profit and loss statements

Here are quick answers to other common questions about P&L statements.

What’s the difference between gross profit and net profit?

Gross profit is revenue minus the direct cost of what you sell, while net profit is what’s left after all other expenses, including interest and tax. A business can show a healthy gross profit and still make a net loss if its overheads are too high.

Is a P&L the same as an income statement?

Yes, P&L, income statement and statement of profit or loss are different names for the same report. Whatever it’s called, check the period it covers before you compare it with another statement.

How often should you prepare a profit and loss statement?

Monthly suits most small businesses, because it lets you fix problems while they’re still small. You’ll also need an annual P&L for your year-end accounts and tax return.

Do sole proprietors in Malaysia need a profit and loss statement?

A P&L is the simplest way to work out the business figures you declare on Form B. It also keeps your business results apart from your personal spending, which makes tax time quicker.
