marginal cost example

Marginal cost can be calculated by dividing the change in _____ ____ by the change in the ______. Alternatively, they may choose to reduce the selling price of their goods to make them more attractive in comparison with the competition. If this resulted in an improved sales volume, their overall level of profitability might stay the same .

In this case, the cost of the new machine would need to be considered in the marginal cost of production calculation as well. A company can maximize its profits by producing to where marginal cost equals marginal revenue . Alternatively, the business may be suffering from a lack of cash so need to sell their products quickly in order to get some cash on hand. It may be to pay for an upcoming debt payment, or, it might just be suffering from illiquidity.


The jewelry factory has expenses that equal about $1,500 in fixed costs per month. If the factory makes 500 bracelets and necklaces per month, then each jewelry item incurs $3 of fixed costs ($1,500 total fixed costs / 500 bracelets and necklaces). The total cost per bracelet and necklace would be $5 ($3 fixed cost per unit + $2 variable costs). Understanding change in costs and change in quantity is an important step of the marginal cost formula. For example, production costs might decrease or increase based on whether or not your company needs more or less output volume. The change in quantity is based on inventory measures at various points in production. During the manufacturing process, a company may become more or less efficient as additional units are produced.

The marginal cost of these is therefore calculated by dividing the additional cost ($20,000) by the increase in quantity , to reach a cost of $0.80 per unit. Under this pricing mechanism, all generators except the marginal unit receive a price that is higher than their marginal cost. Since marginal costs cover only short-term production costs, additional revenues are needed to cover the generator’s long-term fixed costs and ensure ongoing investments in generation. Thus, for the business to be viable, the inframarginal profit must provide the revenues necessary to cover both the short-term and long-term costs of electricity production. The point of transition, between where MC is pulling ATC down and where it is pulling it up, must occur at the minimum point of the ATC curve. That refers to the incremental costs involved in producing additional units. In any marginal cost equation, you’ll need to include the variable costs of production.

What Does It Mean When Marginal Cost Curves Slope Upward, Downward and Horizontally?

In addition to marginal cost, another important metric to consider is marginal revenue. Marginal revenue is the revenue or income to how to calculate marginal cost be gained from producing additional units. This will likely occur when manufacturing needs to increase or decrease output volume.

In this same example, the unit cost when producing one product is $10,010, but then it drops to $5,010 when two units are produced. Both values are important for budgeting, pricing, major capital expansion plans, etc., but be careful not to confuse them. Fixed costs remain the same despite increasing or decreasing the production output. As an example, fixed costs will include rental payments, insurance charges, lease payments, and bank interest payments. You can calculate the Marginal cost by dividing the change in total cost by the change in quantity. The marginal cost of production helps the firm to optimize its production through economies of scale.

More explanations about Production Cost

Constant marginal cost means that the increased cost of production is the same for every unit. In that case, finding the total cost is simply a matter of finding the marginal cost increase for two units and multiplying by the total number for production. Marginal costs are a direct reflection of production quantity and costs, according to our equation above. And since production is a product of cost and quantity, your output directly affects marginal costs. As production increases or decreases, marginal costs can rise and fall. Analysis of the marginal cost helps determine the “optimal” production quantity, where the cost of producing an additional unit is at its lowest point. If changes in the production volume result in total costs changing, the difference is mostly attributable to variable costs.

marginal cost example

In this case, when the marginal cost of the (n+1)th unit is less than the average cost, the average cost (n+1) will get a smaller value than average cost. It goes the opposite way when the marginal cost of (n+1)th is higher than average cost. In this case, The average cost(n+1) will be higher than average cost. Marginal cost is calculated by dividing the change in costs by the change in quantity.

Understanding Marginal Cost

Examples include a social cost from air pollution affecting third parties and a social benefit from flu shots protecting others from infection. Many Post-Keynesian economists have pointed to these results as evidence in favor of their own heterodox theories of the firm, which generally assume that marginal cost is constant as production increases. The marginal cost of production helps you find the ideal production level for your business. You can also use it to find the balance between how fast you should produce and how much production is too low to help growth.

What are the characteristics of marginal cost?

The main characteristics of marginal costing are as follows:

All elements of cost—production, administration and selling and distribution are classified into variable and fixed components. Even semi-variable costs are analysed into fixed and variable. ADVERTISEMENTS: c.

If the marginal cost of producing one additional unit is lower than the per-unit price, the producer has the potential to gain a profit. Average total cost is total cost divided by the quantity of output. Since the total cost of producing 40 haircuts at “The Clip Joint” is $320, the average total cost for producing each of 40 haircuts is $320/40, or $8 per haircut.

Relationship between marginal cost and average total cost

Imagine a company that manufactures high-quality exercise equipment. The company incurs both fixed costs and variable costs, and the company has additional capacity to manufacture more goods. At a certain level of production, the benefit of producing one additional unit and generating revenue from that item will bring the overall cost of producing the product line down. The key to optimizing manufacturing costs is to find that point or level as quickly as possible. The formula above can be used when more than one additional unit is being manufactured. However, management must be mindful that groups of production units may have materially varying levels of marginal cost.

The new plants entering the market tend to have low marginal costs compared to the existing fleet. As long as the new price setters have marginal costs sufficiently higher than the new units, however, the new generator will be profitable and long-term sustainability will be achieved. Since some costs are fixed, there is usually part of the curve on the left where the marginal cost is very high due to an inefficiently low quantity of production. Then, with economies of scale, the marginal cost of production reaches a minimum as the quantity increases.


Investopedia requires writers to use primary sources to support their work. These include white papers, government data, original reporting, and interviews with industry experts. We also reference original research from other reputable publishers where appropriate.

However, demand spikes and they receive more orders, leading them to purchase more materials and hire more employees. In their next production run, they produce 20 units at the cost of $3,000. Costs start out high until production hits the break-even point when fixed costs are covered. It stays at that low point for a period, and then starts to creep up as increased production requires spending money for more employees, equipment, and so on. A good example of this would be marginal cost of production costing more than original production. For instance, in the hat example—if the first batch of hats cost $100 to make but the second batch cost $200 to make, the company is now in a tough spot. It has to either decide on finding a more efficient way to produce the product or raise the prices to see a profit.

We can calculate the marginal cost using the following equation, where ΔTC stands for the change in total cost and ΔQ means the change in the quantity of output. The numerical calculations behind average cost, average variable cost, and marginal cost will change from firm to firm. However, the general patterns of these curves, and the relationships and economic intuition behind them, will not change. Marginal cost is calculated by dividing the increase in production costs by the increase in unit output. It’s essential to have a strong understanding of marginal costs if you want to maximize your profits and decrease the cost-per-unit of production. Find out everything you need to know about how to calculate marginal cost.

What is total cost example?

Total Costs

For example, suppose a company leases office space for $10,000 per month, rents machinery for $5,000 per month, and has a $1,000 monthly utility bill. In this case, the company's total fixed costs would be $16,000.
