If you've ever heard the term "profit and loss statement" and quietly nodded while having absolutely no idea what it means — this article is written for you.
You don't need to be an accountant to understand your business finances. You just need someone to explain it in plain language, without the jargon.
So let's do exactly that.
What is a profit and loss statement?
A profit and loss statement — also called a P&L, an income statement, or a statement of comprehensive income — is a financial report that summarizes three things:
How much money your business earned (income)
How much money your business spent (expenses)
Whether your business made a profit or a loss (the difference)
That's it. At its core, a profit and loss statement answers one simple question: did your business make money during this period?
Why is it called "profit and loss"?
Because the end result is always one of two things:
Profit — your income was higher than your expenses. Your business made money. ✅
Loss — your expenses were higher than your income. Your business spent more than it earned. ❌
The statement shows you exactly which one — and by how much.
What does a profit and loss statement look like?
A basic profit and loss statement has three main sections:
1. Revenue (Income)
This is the total amount your business earned from selling products or services during the period. Every payment received from every client or customer goes here.
Example:
Total revenue: S$18,500
2. Expenses
This is the total amount your business spent to operate during the period. This includes everything — rent, software subscriptions, professional fees, transport, marketing, and any other legitimate business costs.
Example:
Total expenses: S$11,200
3. Net Profit or Net Loss
This is the final number — your revenue minus your expenses. If it's positive, you made a profit. If it's negative, you made a loss.
Example:
Net profit: S$18,500 − S$11,200 = S$7,300
Simple as that.
What period does a profit and loss statement cover?
A profit and loss statement always covers a specific time period — usually:
Monthly — for internal review and tracking
Quarterly — for performance check-ins
Annually — for tax filing and year-end reporting
Unlike a balance sheet which shows a snapshot of one specific date, a profit and loss statement shows everything that happened over a period of time.
Why does your small business need one?
For micro and small business owners, a profit and loss statement serves several critical purposes:
1. Tax filing Your tax authority needs to know how much profit your business made so they can calculate how much tax you owe. The profit and loss statement is the primary document used for this. Without one, your accountant cannot file your taxes accurately.
2. Understanding your business Your bank balance tells you how much cash you have right now. Your profit and loss statement tells you whether your business is actually profitable — which are two very different things.
A business can have a healthy bank balance but still be losing money. A profit and loss statement shows the real picture.
3. Spotting problems early When you review your P&L regularly, patterns become visible. Maybe your expenses are creeping up quietly. Maybe one revenue stream is declining. Maybe your profit margins are shrinking. Catching these early gives you time to act — before they become serious problems.
4. Making better decisions Thinking of hiring someone? Expanding your services? Investing in new equipment? A profit and loss statement gives you the real numbers to make informed decisions — instead of guessing based on your bank balance.
5. Credibility with banks and investors If you ever need a business loan or want to bring in an investor, a clean profit and loss statement is one of the first things they will ask for.
What's the difference between a profit and loss statement and a balance sheet?
This is one of the most common questions small business owners ask. Here's the simplest way to understand it:
Think of it this way — the profit and loss statement is like your business report card for the term. The balance sheet is like a photograph of your business finances on one specific day.
Both tell you something different. Both are important.
How is a profit and loss statement prepared?
A profit and loss statement is prepared from your bookkeeping records. Every transaction that has been recorded, categorised, and reconciled throughout the period gets summarised into the statement.
This is why clean, accurate bookkeeping is so important. If your records are incomplete or inaccurate, your profit and loss statement will be wrong — and everything built on top of it (your tax filing, your business decisions, your loan applications) will be wrong too.
The process looks like this:
Step 1 — All income transactions are recorded and totalled
Step 2 — All expense transactions are recorded, categorised, and totalled
Step 3 — Expenses are subtracted from income
Step 4 — The result is your net profit or net loss
When your bookkeeping is done properly throughout the year, preparing a profit and loss statement is straightforward. When it isn't — it becomes a painful, expensive exercise in reconstruction.
How often should you review your profit and loss statement?
For micro and small businesses, reviewing your P&L monthly is ideal. It takes less than 10 minutes to read and gives you a clear picture of how your business performed that month.
Waiting until year end to look at your P&L is like driving with your eyes closed for 12 months and then checking where you ended up. By the time you see the problem, it's too late to fix it.
