Definition

Noun The additional cost incurred when producing one more unit of a good or service, or the cost saved when producing one less unit. It is the change in total cost resulting from a one-unit change in output quantity.

Usage

This term is used primarily in economics, business, finance, and accounting to analyze the financial impact of small changes in production volume or activity level. It is a key concept for decision-making regarding production levels, pricing, and resource allocation.

Examples

• The incremental cost of manufacturing one additional car includes the direct materials and labor required for that unit.
• Before expanding production, the company calculated the incremental cost to ensure the new units would be profitable.
• The decision to run the factory for an extra hour depends on whether the revenue from the extra output covers its incremental cost.

Advanced Usage

• Incremental Cost Analysis: A decision-making process that compares the additional costs of an action to its additional benefits (incremental revenue).
  • The management team used incremental cost analysis to evaluate the new project proposal.
• Often contrasted with sunk cost (a past cost that cannot be recovered and should not affect future decisions) and average cost (total cost divided by the number of units).

Variants and Related Words

• Marginal Cost: A term often used synonymously with "incremental cost" in economic theory, though "marginal" can imply an infinitesimally small change.
• Differential Cost: Another synonym, emphasizing the difference in total cost between two alternative courses of action.

Synonyms

• Marginal cost
• Differential cost

Antonyms

• Sunk Cost: A cost that has already been incurred and cannot be recovered.
• Fixed Cost: A cost that does not change with the level of output in the short term (e.g., rent, salaries).

Noun

1. the increase or decrease in costs as a result of one more or one less unit of output
