Your profit and loss statement lands in your inbox every month, and if you are honest, you scroll straight to the bottom line. Up or down? Then you close it and get back to work.

That habit is understandable, but it wastes the most useful report your accountant gives you. The P&L tells you where your money comes from, where it leaks and which decisions are paying off. You simply need to know where to look.

This guide walks you through the P&L line by line, using an illustrative Rand example. By the end, you will know which numbers to check first, which ratios matter and what questions to ask your bookkeeper.

What is a profit and loss statement?

A profit and loss statement, also called an income statement, shows your revenue and expenses over a set period, usually a month, quarter or year. The difference between the two is your profit or loss for that period.

It differs from the other two main financial reports. The balance sheet is a snapshot of what you own and owe on one date. Meanwhile, the cash flow statement shows how cash actually moved in and out of your bank account. The P&L measures performance, but it does not tell you whether you have cash.

That distinction matters. Xero’s 2026 State of South African Small Business report found that 75% of small firms increased profits over the past year. Yet 62% also experienced cash flow issues in the same period. Profit and cash are related, but they are not the same thing.

An example P&L in Rand

Picture a Johannesburg distributor of industrial cleaning products with 45 staff. Here is a simplified annual P&L. The figures are illustrative, not from a real business.

Line itemAmount (R)% of revenue
Revenue (excl. VAT)24,000,000100.0%
Cost of sales(16,800,000)70.0%
Gross profit7,200,00030.0%
Salaries and wages(3,600,000)15.0%
Rent and utilities(720,000)3.0%
Vehicles and fuel(600,000)2.5%
Marketing(240,000)1.0%
Admin, IT and insurance(360,000)1.5%
Total operating expenses(5,520,000)23.0%
EBITDA1,680,0007.0%
Depreciation(300,000)1.25%
Operating profit (EBIT)1,380,0005.75%
Interest paid(420,000)1.75%
Net profit before tax960,0004.0%
Income tax at 27%(259,200)1.08%
Net profit after tax700,8002.9%

At first glance, R24 million in sales looks impressive. However, after every cost is paid, the owner keeps about R2.90 out of every R100 sold. That is the story your P&L tells, if you read it top to bottom.

How to read a profit and loss statement, line by line

1. Revenue

Revenue is what you invoiced during the period, excluding VAT. It is not the money that arrived in the bank. So if a large client pays on 90-day terms, the sale shows here long before the cash does. Check revenue against last month, the same month last year and your budget.

2. Cost of sales and gross profit

Cost of sales covers the direct cost of what you sold: stock, direct labour, freight in and subcontractors. Gross profit is what remains. In our example, the gross margin is 30%, which means R30 of every R100 is left to pay for everything else.

Gross margin is often the first place trouble shows. For instance, if a supplier raises prices by 5% and you don’t pass it on, your margin quietly shrinks while revenue looks healthy.

3. Operating expenses

These are the overheads of running the business: salaries, rent, vehicles, marketing, software and insurance. They tend to creep up slowly. Therefore, compare each line as a percentage of revenue over several months, as well as in Rand.

4. EBITDA and operating profit

EBITDA (earnings before interest, tax, depreciation and amortisation) shows how much the core operation earns before financing and asset costs. Banks and buyers look at it closely. Operating profit then subtracts depreciation, which spreads the cost of equipment and vehicles over their useful life.

5. Interest, tax and net profit

Interest shows the cost of your debt. Tax follows, and South African companies currently pay income tax at 27%, according to PwC’s worldwide tax summaries. Qualifying small business corporations pay lower graduated rates. Finally, net profit after tax is what belongs to the owners, whether you pay it out or reinvest it.

Five ratios every owner should check on the P&L

Rand figures tell you what happened. Ratios, on the other hand, tell you whether it is getting better or worse. These five are enough for a monthly review.

RatioFormulaExample resultWhat it tells you
Gross marginGross profit ÷ revenue30.0%Whether pricing and buying are under control
Overhead ratioOperating expenses ÷ revenue23.0%Whether fixed costs grow faster than sales
Wage ratioSalaries ÷ revenue15.0%Whether headcount matches the work
EBITDA marginEBITDA ÷ revenue7.0%How profitable the core operation is
Net marginNet profit after tax ÷ revenue2.9%What the owner keeps from each Rand sold

Benchmarks vary widely by industry. For example, Stats SA reported that the profit margin in real estate and business services was 12.2% in 2024, with real estate activities at 31.0%. A distributor like our example would expect much thinner margins. As a result, your own trend over time is usually a better guide than a national average.

What the profit and loss statement won’t tell you

A P&L is powerful, but it has blind spots. Keep these in mind before you celebrate a good month:

In short, read the P&L together with your balance sheet and cash flow forecast. Each one answers a different question.

Questions to ask when you review your P&L

A monthly review doesn’t need to take more than 30 minutes. Work through these questions with your finance person or bookkeeper:

  1. Is revenue on budget, and which customers or products drove the change?
  2. Did gross margin move by more than one percentage point? If so, why?
  3. Which overhead line grew faster than revenue?
  4. Are there once-off items that distort the month, such as a bonus or a large repair?
  5. How does net profit compare with the same month last year?
  6. What one action will we take because of these numbers?

That last question is the one most owners skip. A report that doesn’t change a decision is just paperwork. If margins are slipping, look at your pricing strategy first. If overheads are rising, a structured approach to cost reduction that protects growth is a sensible next step.

It also helps to work closely with your accountant. The same Xero survey found that 77% of South African small businesses see their accountant or bookkeeper as their most trusted advisor. So use that relationship for insight as well as compliance.

Frequently asked questions

Is a profit and loss statement the same as an income statement?

Yes. P&L, profit and loss account and income statement all describe the same report. It lists revenue, cost of sales, operating expenses, interest and tax for a period and shows the resulting profit or loss. Accountants in South Africa often say “income statement”, while owners usually just call it the P&L.

Why is my business profitable but short of cash?

Profit is recorded when you invoice, not when clients pay. So slow-paying debtors, stock purchases, loan capital repayments and VAT payments can all drain cash while the P&L shows a profit. Review your debtors’ book and a 13-week cash flow forecast alongside the P&L to see the full picture.

How often should I review my P&L?

Review it monthly, within two to three weeks of month-end. Quarterly is too slow, because problems like shrinking margins compound quickly. Compare each month with budget and with the same month last year, and track four or five key ratios so that trends become visible early.

What is a good net profit margin for a small business?

It depends heavily on the industry. Distributors and contractors often run low single-digit net margins, while professional services and software can earn far more. Rather than chase a universal number, check that your net margin covers reinvestment, debt repayments and a fair return for the risk you carry, and that it is trending up.

Turn your P&L into decisions

Reading your profit and loss statement well is one of the simplest ways to take back control of your business. Start this month. First, calculate the five ratios above. Then compare them with last year. Finally, agree on one action with your team.
