# How to Calculate Marginal Revenue: A Guide for Beginners

Summary：Learn how to calculate marginal revenue with our beginner's guide. Marginal revenue helps businesses determine the optimal price to sell their products or services.

Marginal revenue is a key concept in economics that helps businesses determine the optimal price to sell their products or services. It is the additional revenue generated from selling one more unit of a product or service. In this article, we will guide you on how to calculatemarginal revenueand provide some practical applications of this concept.

What is Marginal Revenue?

Marginal revenue is the additional revenue generated from selling one more unit of a product or service. It is calculated by dividing the change in total revenue by the change in quantity sold. In other words, it is the derivative of the total revenue function with respect to quantity sold.

For example, if a business sells 100 units of a product and generates \$10,000 in revenue, and then sells 101 units of the same product and generates \$10,200 in revenue, the marginal revenue for the 101st unit is (\$10,200 - \$10,000) / (101 - 100) = \$200.

Why is Marginal Revenue Important?

Marginal revenue is important because it helps businesses determine the optimal price to sell their products or services. By calculating marginal revenue, businesses can determine whether it is profitable to sell one more unit of a product or service at a certain price. If the marginal revenue is positive, it means that selling one more unit will increase the total revenue. If the marginal revenue is negative, it means that selling one more unit will decrease the total revenue.

How to Calculate Marginal Revenue?

To calculate marginal revenue, you need to follow these steps:

1. Determine the total revenue generated from selling a certain quantity of a product or service.

2. Sell one more unit of the same product or service at a certain price.

3. Determine the total revenue generated from selling the new quantity of the product or service.

4. Subtract the original total revenue from the new total revenue.

5. Divide the result by the change in quantity sold.

For example, let's say a business sells 100 units of a product at \$50 each and generates \$5,000 in total revenue. The business then sells one more unit at \$50 and generates \$5,050 in total revenue. The marginal revenue for the 101st unit is (\$5,050 - \$5,000) / (101 - 100) = \$50.

Applications of Marginal Revenue

1. Pricing Strategy: Marginal revenue can help businesses determine the optimal price to sell their products or services. By calculating the marginal revenue at different price points, businesses can determine the price that maximizes their profit.

2. Production Decisions: Marginal revenue can also help businesses make decisions about how much to produce. By calculating the marginal revenue at different levels of production, businesses can determine the level of production that maximizes their profit.

3. Investment Decisions: Marginal revenue can also be used to makeinvestment decisions. By calculating the marginal revenue of different investment opportunities, businesses can determine which investments are most profitable.

Conclusion

Marginal revenue is a key concept in economics that helps businesses determine the optimal price to sell their products or services. It is the additional revenue generated from selling one more unit of a product or service. By calculating marginal revenue, businesses can make informed decisions about pricing, production, and investment.
