What Is Profit, Simply?

What profit means in plain words, the difference between revenue and profit, and why profit matters for businesses, workers and the economy.

You often hear that a company “made a profit” or “made a loss”. But what exactly is profit?

Revenue and costs

Revenue is all the money a business receives from selling its goods or services.
Costs are all the money it spends to run the business: materials, wages, rent, electricity, transport, interest on loans and taxes.

Profit is what is left after subtracting costs from revenue:

Profit = Revenue - Costs

If costs are higher than revenue, the business makes a loss.

A simple example

A lemonade stall sells 100 glasses at 20 rupees each: revenue is 2,000 rupees. Lemons, sugar, cups and the stall rent cost 1,400 rupees. Profit is 600 rupees.

Profit margin

The profit margin shows how much of each rupee of sales becomes profit. In the example, 600 divided by 2,000 is 30 percent. Different industries have very different margins: supermarkets often earn thin margins, while software companies can earn much higher ones.

Why profit matters

Rewards risk: owners invest money and take risks; profit is their reward.
Signals demand: high profits show that people want a product, attracting more businesses to supply it.
Funds growth: profits can be reinvested to expand, hire more people and innovate.
Pays taxes: companies pay tax on profits, funding public services.

Profit is not everything

A business with high revenue can still make a loss if costs are higher.
Cash and profit are different: a business can be profitable but run out of cash if customers pay late.
Some organisations, such as non-profits, aim to serve a mission rather than earn profits.
Profits made by harming people or the environment raise ethical questions.

The busy restaurant

A restaurant is full every night and takes in 5 lakh rupees a month. But rent, staff, ingredients and loan payments add up to 5.2 lakh rupees. Despite being busy, it makes a loss. Revenue alone does not show whether a business is healthy.

Thinking revenue and profit are the same

Revenue is the money coming in; profit is what remains after all costs. A business can have high revenue and still lose money.

Key takeaways

Profit equals revenue minus costs.
The profit margin shows how much of each rupee of sales becomes profit.
Profit rewards risk, signals demand and funds growth.
High revenue does not guarantee profit, and profit is not the same as cash.
