How Businesses Make Money
Revenue Streams, Costs & Profits
Learn the mechanics behind income generation and sustainable growth. 

At its core, every business—whether a small shop or a global corporation—exists to create value and earn money.
But how exactly does a business generate income? What determines profit? And why do some businesses thrive while others struggle?

Understanding revenue, costs, and profit is essential for entrepreneurs, managers, and anyone wanting to understand how companies operate. 

Revenue is the total amount of money a business earns from selling its products or services.
Common revenue sources include:

🔹 Product Sales

Selling physical goods like electronics, clothing, or groceries.

🔹 Service Revenue

Income from services such as consulting, education, maintenance, or subscriptions.

🔹 Subscription & Membership Fees

Recurring monthly or yearly payments (Netflix, gyms, SaaS products).

🔹 Advertising Revenue

Earnings from promoting other brands (Google, Meta, YouTube).

🔹 Commission-Based Revenue

Platforms like Uber, Amazon, or food delivery apps take a percentage of each transaction.

🔹 Licensing & Royalties

Companies like Disney earn royalties when others use their characters or content.

🔹 Rental or Leasing revenue

Property owners, automobile leasing companies, or equipment rentals.

In short, revenue is everything a business earns before subtracting expenses.

Every business spends money to operate. These expenses are called costs.

⚙️ Operating Costs

Everyday expenses: salaries, electricity, rent, internet, software.

🏭 Production/Manufacturing Costs

Raw materials, machinery, packaging.

📦 Distribution Costs

Shipping, logistics, delivery fees.

📣 Marketing & Sales Costs

Advertisements, promotions, sales commissions.

🛠️ Maintenance & Support Costs

Customer support, repairs, updates.

📉 Depreciation

The decreasing value of equipment or machinery over time.

💰 Financial Costs

Interest on loans, bank fees, taxes.

Profit shows how well a business is performing financially.
It is calculated as:

💡 Profit = Revenue – Costs

There are three key types of profit:

1️⃣ Gross Profit

Revenue minus the cost of producing the goods.

2️⃣ Operating Profit

Gross profit minus operating expenses (rent, salaries, etc.).

3️⃣ Net Profit

The final profit after subtracting taxes, interest, and all remaining expenses.

Net profit is the number business owners watch most closely.
