It answers the question: “Did we make or lose money during a period of time?”
Income Statement
All the money the company earned from its regular business (like selling products or services).
Revenue
All the costs the company had to pay to make that revenue (like employee salaries, rent, marketing, and the cost of materials).
Expenses
Basic Formula
Revenue (Money In) - Expenses (Money Out) = Net Income (The Profit!)
Income Statement other names
A company can show P&L as its own standalone report, or it can be the first half of a bigger report called the…
Statement of Comprehensive Income.
Reasons why Income Statement matters:
Growth: The stock market loves profit growth. A company whose profits are growing quickly will often have a higher stock price.
Valuation: The “profit” number (or “earnings”) is the most important ingredient analysts plug into their formulas to figure out what a stock should be worth.
“Is this company making enough profit to safely pay its bills and its loan payments?”
Another way of looking at Income Statement
The very first line (“Top Line”) on the P&L is almost always…
Revenue.
This is the total amount of money a company earned from its regular business (selling goods or services).

Other names for Revenue
“Sales”, “Turnover”

Revenue
“Bottom Line” is also called
Net Income, Profit of the year, Net earnings
Why it’s called the “Bottom Line”?
Because it’s literally at the bottom of the P&L, and it’s the final result of all the business activities.
Bottom Line: On non-controlling interests
Accounting rules (called consolidation) say that if you own more than 50% of a company, you must report 100% of its revenue and 100% of its expenses, all mashed together with your own.
Example for consolidation case
Let’s say AB InBev owns 80% of a smaller brewery. That brewery made $100M in profit.
• AB InBev has to add that entire $100M to its own P&L to get its “Net Income.”
• But… AB InBev doesn’t really get to keep all $100M. It only gets to keep its 80% share ($80M).
• The other 20% ($20M) belongs to the other 20% owners. This is the “noncontrolling interest.”

Gains and losses vs. Revenue and expenses
Revenue & Expenses: Come from the company’s normal, ordinary business (making and selling beer).
Gains & Losses: Come from one-time, non-ordinary events. For example, if AB InBev sold a surplus factory, the profit (or loss) from that sale is a “Gain” or “Loss,” not “Revenue.”
How are Expenses organized?
By nature and by function
By Nature (What it is)
All similar types of costs are lumped together. You’d see lines like:
• Depreciation Expense (for all assets)
• Salary Expense (for all employees)
• Marketing Expense

By Function (Why you spent it)
Costs are grouped by the business purpose they served. You see lines like:
• Cost of Sales: Includes all costs to make the product (raw materials, factory worker salaries, factory depreciation).
• Selling & Marketing Expenses: Includes all costs to sell the product (sales team salaries, advertising, etc.).
• Administrative Expenses: Includes all costs to run the company (HQ rent, CEO’s salary).

It’s one simple calculation.
(All Revenues + All Gains) - (All Expenses + All Losses) = Net Income.
