Incremental cost is a financial concept that is used to help determine the profitability of different business segments. It is the added cost associated with producing an additional unit of a product or expanding a business into a new area. It is important to remember that incremental cost is only part of the equation; the overall profitability of a business venture depends on the total cost compared to the total revenue.

To understand incremental cost, it is important to understand the concept of marginal cost. Marginal cost is the cost of producing one additional unit of a product and includes all associated materials, labour, transportation and fixed costs. By comparison, incremental cost accounts for all associated costs in addition to the marginal cost to produce one additional unit. For example, a company that produces a new product might have a startup cost. This startup cost is an example of an incremental cost that is not associated with the marginal cost of producing one unit of the product.

Incremental cost analysis can help a company decide whether or not to pursue a particular business venture. The company will determine the total cost of producing the additional unit and compare it to the expected incremental revenue from sales. If the incremental cost exceeds the incremental revenue, then the company will lose money on each additional unit produced or sold. This is especially true for businesses that do not have the bargaining power or economies of scale to increase the profit margin on each additional unit produced.

Incremental cost analysis is an important part of financial decision making. It can help companies identify opportunities to increase their profitability by eliminating, reducing or matching incremental costs with incremental revenue. Companies should consider all aspects of a project before making a decision, including costs associated with production, market trends, consumer preferences and expected sales before committing to a new venture. Incremental cost analysis can provide the necessary data to develop a profitable strategy for expanding a business or launching a new product.
