4.4.4. The Normal Profit and Break-even Point

The minimum level of profit that is needed to keep a firm in the existing business is defined as normal profit. A firm that does not make normal profits is not going to continue in business.

Normal profit is the minimum profit required for a firm to remain operational. It is not a reward for risk or entrepreneurship but simply a part of the total costs the firm incurs. If a firm isn't making at least this profit, it will exit the market, as it isn't covering the opportunity costs associated with its resources.

Imagine you run a coffee shop. If the profit you make each month isn't enough to pay your bills, staff, and cover other costs, you start losing money. Eventually, you decide to close the shop if you can't at least cover these basic expenses with your earnings, which is akin to not making normal profit.

Profit that a firm earns over and above the normal profit is called the super-normal profit.

Super-normal profit refers to earnings that exceed what is necessary to keep the business functional. This is where a firm is not only covering costs but also making additional profits. Such profits can indicate a well-performing business, potentially allowing for reinvestment and growth.

Using our coffee shop example, if you make enough profit to cover all your costs and still have some money left over to invest in new equipment or advertising, that's super-normal profit. It shows that aside from basic sustainability, your business is thriving.

In the long run, a firm does not produce if it earns anything less than the normal profit. In the short run, however, it may produce even if the profit is less than this level.

This concept highlights that firms can sustain operations in the short run, even with minimal profits or losses, if they can cover variable costs. However, in the long run, a firm must make at least normal profits to justify its ongoing operation because consistent losses aren't sustainable.

Think of a movie theater. In the short term, if ticket sales dip but enough to cover salaries and utilities, it might continue operating. However, after some time, if ticket sales do not improve and it can't cover all its costs, it will have to shut down.

The point on the supply curve at which a firm earns only normal profit is called the break-even point of the firm.

The break-even point is where total revenue equals total costs, resulting in zero profit. This is critical for a firm, as it identifies the minimum output needed to avoid losses. Beyond this point, the firm begins to make profits, while below it, the firm incurs ongoing losses.

In our coffee shop scenario, the break-even point might be selling 100 cups of coffee per day to cover all costs. If it sells 100 or more cups, it breaks even or profits; if it sells less than 100, it's losing money.

Opportunity cost of some activity is the gain foregone from the second best activity. Suppose you have Rs 1,000 which you decide to invest in your family business. What is the opportunity cost of your action?

Opportunity cost is crucial in economic decision-making. It refers to the potential benefits lost when choosing one option over the next best alternative. This concept helps individuals and businesses evaluate the true cost of a decision beyond mere finances.

Consider a chef who decides to open a restaurant instead of working at a corporate job that pays Rs 1,200 a month. If the chef invests Rs 1,000 into the restaurant, the opportunity cost includes the salary he would have earned at the corporate job plus any potential interest income lost by not saving that Rs 1,000.
