What it means
The statement is built as a ladder. At the top is revenue, the money earned from customers.
Below it come the costs of producing what was sold, then the operating expenses of running the business, then interest and tax, leaving net profit at the bottom. Each rung gives a different insight.
Gross profit, which is revenue minus the direct cost of sales, shows how well the core product earns. Operating profit, after overheads such as salaries and rent, shows how profitable the day-to-day business is, and net profit shows what is left for owners after everything.
Managers use the statement to judge performance, set budgets and decide where to cut or invest. Lenders and investors use it to judge whether a business can afford its debts and whether profits are growing.
Comparing the same statement across periods, or against budget, shows trends that a single number cannot. The statement is prepared on an accruals basis, which means revenue is recorded when it is earned and costs when they are incurred, not when cash moves.
So a business can show a profit and still run short of cash if customers pay late. That is why the profit and loss statement is read together with the cash flow statement and the balance sheet.
Layout varies by country and industry, and some businesses report by function while others report by the nature of the expense. Common one-off items, such as a gain on selling a building, are usually shown separately so readers can see the underlying performance.
A good habit is to read from the top down and ask what changed at each level. Comparisons give the statement its power.
Placing the current period beside the same period last year, and beside the budget, shows whether a result is good, bad or simply normal for the season. Many managers also express each line as a percentage of revenue so that changes in mix stand out.
In practice
Real-world examples
Example 1
A cafe owner reviews her monthly profit and loss statement and sees that revenue is up 6% but profit is down. Milk and coffee costs rose faster than sales, so she reviews her supplier prices and adjusts the menu. Within two months the margin on drinks is back to its earlier level.
Example 2
A software company shows strong revenue growth but a net loss because of heavy investment in engineers. Investors read the statement to see whether losses are narrowing as sales grow.
Example 3
A bank loan officer asks a small manufacturer for the last three years of statements. She looks at whether operating profit covers interest payments comfortably before approving a loan, because a business that only just covers interest has little room for a bad year.
Think of it
A P&L statement is like your monthly budget review-what money came in, what went out, and whether you ended up ahead or behind.
Formula
Calculation
Net profit = revenue - cost of sales - operating expenses - interest - tax
Suppose a company has revenue of $800,000 and cost of sales of $480,000, so gross profit is 800,000 - 480,000 = $320,000. Operating expenses are $200,000, so operating profit is 320,000 - 200,000 = $120,000. Interest of $20,000 leaves profit before tax of $100,000. Assuming a 25% tax rate, tax is $25,000 and net profit is 100,000 - 25,000 = $75,000.Case study
Seen in the real world
Ridgeway Interiors is an illustrative, fictional design studio whose owner believed the business was thriving because the diary was full. The first full profit and loss statement showed revenue of $600,000 but net profit of only $18,000.
The owner traced the problem to two lines: subcontractor costs, which had grown to 55% of revenue, and a rent bill for office space used only part of the week. After renegotiating subcontractor rates and moving to a smaller office, net profit in the next year rose to $66,000 on similar revenue. The illustrative lesson is that busy is not the same as profitable.
The studio now prepares a statement every month and reviews it with the owner within ten days of month end. The illustrative owner says the discipline of reading the statement top to bottom was the most valuable change in the whole business.
Watch out
Common mistakes
- Treating profit as cash, when the statement uses accruals and profit can exist without cash in the bank.
- Looking only at revenue growth and ignoring what happened to costs further down the statement.
- Comparing periods of different lengths without adjusting, so a four-week month is judged against a five-week month.
Questions
People also ask
Is a profit and loss statement the same as an income statement?
Yes, the two names describe the same report, with different names used in different countries and industries.
What is the difference between gross profit and net profit?
Gross profit deducts only the direct cost of sales, while net profit deducts all costs including overheads, interest and tax.
How often should a profit and loss statement be produced?
Monthly is common for management, with quarterly and annual versions for owners, lenders and regulators.
