# Marginal revenue and marginal cost relationship

The marginal cost curve falls briefly at first, then rises. How is marginal revenue related to the marginal cost of production? By Mary Hall Updated June 14, — 2: A rational company always seeks to maximize its profitand the relationship between marginal revenue and the marginal cost of production helps to find the point at which this occurs.

Calculating Marginal Cost of Production Production costs include every expense associated with making a good or service. These costs are broken down into fixed costs and variable costs.

## BREAKING DOWN 'Marginal Revenue (MR)'

Fixed costs are the relatively stable, ongoing costs of operating a business that are not dependent on production levels. Fixed costs include general overhead expenses like salaries and wages, building rental payments or utility costs. Variable costs are those directly related to, and that vary with, production levels, such as the cost of materials used in production or the cost of Marginal revenue and marginal cost relationship machinery in the process of production.

Total production costs include all the expenses of producing product at current levels: A company that makes widgets has production costs for all units it produces. The marginal cost of production is the cost of producing one additional unit. At some point, the company reaches its optimum production level, the point at which producing any more units would increase the per-unit production cost.

For example, increased production beyond a certain level may involve paying prohibitively high amounts of overtime pay to workers, or the maintenance costs for machinery may significantly increase. The marginal cost of production measures the change in total cost of a good that arises from producing one additional unit of that good.

Using calculus, the marginal cost is calculated by taking the first derivative of the total cost function with respect to the quantity: Marginal costs of production may change as production capacity changes. If, for example, increasing production from to units per day requires a small business to purchase additional business equipment, then the marginal cost of production may be very high.

However, this expense may be significantly lower if the business is considering an increase from to units using existing equipment.

A lower marginal cost of production means that the business is operating with lower fixed costs at a particular production volume. Calculating Marginal Revenue Marginal revenue measures the change in the revenue when one additional unit of a product is sold.

The marginal revenue is calculated by dividing the change in the total revenue by the change in the quantity. In calculus terms, the marginal revenue is the first derivative of the total revenue function with respect to the quantity: The total revenue is calculated by multiplying the price by the quantity produced.

In terms of calculus, the relationship is stated as: When marginal revenue is less than the marginal cost of production, a company is producing too much and should decrease its quantity supplied until marginal revenue equals the marginal cost of production.

When the marginal revenue is greater than the marginal cost, the firm is not producing enough goods and should increase its output until profit is maximized.

How Can Marginal Revenue Increase? Marginal revenue increases whenever the revenue received from producing one additional unit of a good grows faster or shrinks more slowly than its marginal cost of production. Increasing marginal revenue is a sign that the company is producing too little relative to consumer demand, and there are profit opportunities if production expands.

This is an example of increasing marginal revenue. For any given amount of consumer demand, marginal revenue tends to decrease as production increases.

In equilibriummarginal revenue equals marginal costs; there is no economic profit in equilibrium. Markets never reach equilibrium in the real world; they only tend toward a dynamically changing equilibrium.

As in the example above, marginal revenue may increase because consumer demands have shifted and bid up the price of a good or service. It could also be that marginal costs are lower than they were before. Marginal costs decrease whenever the marginal revenue product of labor increases — workers become more skilled, new production techniques are adopted, or changes in technology and capital goods increase output.

It could either add additional products or additional features to its existing products to increase the expected decline in marginal revenue.

## What is 'Marginal Revenue (MR)'

For related reading, see:In economics, profit maximization is the short run or long run process by which a firm may determine the price, input, and output levels that lead to the greatest profit. Neoclassical economics, currently the mainstream approach to microeconomics, usually models the firm as maximizing profit..

There are several perspectives one can take on this problem. First, since profit equals revenue minus. The relationship between average cost and marginal cost can be easily explained via a simple analogy.

Rather than think about costs, let's think about grades on a series of exams for a second. The costs and revenues of a firm determine its nature and the levels of profit.

The revenue concepts commonly used in economic are total revenue, average revenue and marginal revenue. Total Utility and Marginal Utility: Difference Between Total Utility and Marginal Utility: People buy goods because they get satisfaction from them. Marginal Cost. Marginal cost is the change in total cost which occurs when the number of units produced change by just one unit.

In other words, marginal revenue is the cost of producing one additional unit of a particular good. Marginal Cost (MC): Definition: Marginal Cost is an increase in total cost that results from a one unit increase in output. It is defined as: "The cost that results from a one unit change in the production rate".
