How Businesses Make Money

Revenue is the money coming in. Costs are the money going out. Profit is what remains. Simple to say, hard to master.

The Three Numbers Every Business Lives By

Every business, from a street vendor to a multinational company, lives by three numbers:

Revenue (Money Coming In)

This is all the money customers pay you. If you sell 10 samosas at Rs 20 each, your revenue is Rs 200. Revenue is the top number, but it is not the most important one.

Costs (Money Going Out)

This is all the money you spend to run the business. Ingredients, rent, wages, electricity, transport—everything adds up. If it costs Rs 8 to make each samosa, your cost for 10 is Rs 80.

Profit (What Remains)

Revenue minus Costs equals Profit. If revenue is Rs 200 and costs are Rs 80, your profit is Rs 120. This is the money that keeps the business alive.

Revenue − Costs = Profit

The Trap of Big Revenue

Many people think a business is doing well because it has lots of customers and lots of sales. But revenue without profit is just activity, not success.

Consider two businesses:

Business A

  • Revenue: Rs 10,00,000
  • Costs: Rs 9,50,000
  • Profit: Rs 50,000

Business B

  • Revenue: Rs 3,00,000
  • Costs: Rs 1,50,000
  • Profit: Rs 1,50,000

Business A looks bigger but Business B is healthier. It keeps more of what it earns. Big revenue with tiny profit means lots of work for little reward.

Different Ways to Make Money

Businesses earn money in many ways. Here are the most common:

  • •Selling Products: Make or buy something, sell it for more. A shop, a factory, an online store.
  • •Selling Services: Use your skills or time to help others. A tutor, a doctor, a web designer.
  • •Subscriptions: Charge regularly for ongoing access. Netflix, gym memberships, newspapers.
  • •Advertising: Offer something free, earn from showing ads. YouTube, newspapers, free apps.
  • •Commission: Connect buyers and sellers, take a percentage. Real estate agents, delivery apps.
  • •Rent: Own something valuable, let others use it for a fee. Property, equipment, vehicles.

Some businesses use multiple ways. A shopping app might sell products, show ads, and charge sellers a commission—all at once.

Profit is the Survival Fund

Why does profit matter so much? Because profit is what allows a business to:

  • •Survive bad times: When sales drop, profit from good times keeps you alive
  • •Grow: Open new locations, hire more people, make better products
  • •Improve: Buy better equipment, train staff, innovate
  • •Reward: Pay the owner for their work and risk

A business with no profit is living on borrowed time. It might look busy, but one bad month can end everything. Profit is the cushion that protects against uncertainty.

Remember: Cash Flow Matters Too

If you studied the Money topic, you learned about cash flow: the timing of money coming in and going out. Here is why it matters for profit:

A business can be profitable on paper but still fail. How? If costs come before revenue. Imagine:

  • •January: You spend Rs 50,000 on supplies
  • •February: You make products, no sales yet
  • •March: Rent is due, you have no money
  • •April: You would have sold everything for Rs 80,000—but you closed in March

Profit is calculated over time, but bills are paid in the moment. Managing cash—not just profit—is essential for survival.

Ancient Wisdom: Chanakya on Treasury Management

Chanakya advised kings on managing the royal treasury. His principles apply perfectly to business:

"कोशमूलो दण्डः। दण्डमूलाः सर्वारम्भाः॥"

Meaning: "The treasury is the root of all power. And all enterprises depend on that power."

Chanakya also taught about growing the treasury wisely:

"कोशस्य हि वृद्धौ देशवृद्धिः, देशवृद्धौ प्रजावृद्धिः।"

Meaning: "When the treasury grows, the state grows. When the state grows, the people prosper."

In modern terms: A healthy treasury (profit) is not selfish—it is the foundation of everything else. A business with strong profits can serve customers better, pay workers well, and contribute to society. Profit enables purpose.

Reflection Question

Think about a local business you visit often—a shop, restaurant, or service. What do you think their main costs are? What would happen to them if revenue dropped by 50% for three months?

There is no right answer. The point is to start thinking about the money behind businesses you interact with.
