Definition of incremental cost

incremental cost

the cost of producing or selling an additional
contemplated quantity of output

Incremental cost

The difference in costs between alternative actions.

Incremental costs and benefits

costs and benefits that would occur if a particular course of action were
taken compared to those that would occur if that course of action were not taken.

incremental separate cost

the cost that is incurred for each
joint product between the split-off point and the point of sale

Agency costs

The incremental costs of having an agent make decisions for a principal.

economically reworked

when the incremental revenue from the sale of reworked defective units is greater than
the incremental cost of the rework

relevant costing

a process that compares, to the extent possible
and practical, the incremental revenues and incremental costs of alternative decisions

Hurdle rate

The minimum rate of return that a capital purchase proposal must pass
before it can be authorized for acquisition. The hurdle rate should be no lower than
a company’s incremental cost of capital.

Accelerated cost recovery system (ACRS)

Schedule of depreciation rates allowed for tax purposes.

Agency cost view

The argument that specifies that the various agency costs create a complex environment in
which total agency costs are at a minimum with some, but less than 100%, debt financing.

All-in cost

Total costs, explicit and implicit.

Average cost of capital

A firm's required payout to the bondholders and to the stockholders expressed as a
percentage of capital contributed to the firm. Average cost of capital is computed by dividing the total
required cost of capital by the total amount of contributed capital.

Bankruptcy cost view

The argument that expected indirect and direct bankruptcy costs offset the other
benefits from leverage so that the optimal amount of leverage is less than 100% debt finaning.

Carring costs

costs that increase with increases in the level of investment in current assets.

Cost company arrangement

Arrangement whereby the shareholders of a project receive output free of
charge but agree to pay all operating and financing charges of the project.

Also called price impact costs, the result of a bid/ask spread and a dealer's price concession.

Market timing costs

costs that arise from price movement of the stock during the time of the transaction
which is attributed to other activity in the stock.

Net financing cost

Also called the cost of carry or, simply, carry, the difference between the cost of financing
the purchase of an asset and the asset's cash yield. Positive carry means that the yield earned is greater than
the financing cost; negative carry means that the financing cost exceeds the yield earned.

Opportunity cost of capital

Expected return that is foregone by investing in a project rather than in
comparable financial securities.

Opportunity costs

The difference in the performance of an actual investment and a desired investment
adjusted for fixed costs and execution costs. The performance differential is a consequence of not being able

True interest cost

For a security such as commercial paper that is sold on a discount basis, the coupon rate
required to provide an identical return assuming a coupon-bearing instrument of like maturity that pays
interest in arrears.

Variable cost

A cost that is directly proportional to the volume of output produced. When production is zero,
the variable cost is equal to zero.

A division or unit of an organization that is responsible for controlling costs.

Cost control

The process of either reducing costs while maintaining the same level of productivity or maintaining costs while increasing productivity.

Weighted average cost of capital

See cost of capital.

Cost of goods sold

The cost of the items that were sold during the current period.

activity based costing (ABC)

A relatively new method advocated for the
allocation of indirect costs. The key idea is to classify indirect costs,
many of which are fixed in amount for a period of time, into separate
activities and to develop a measure for each activity called a cost driver.
The products or other functions in the business that benefit from the
activity are allocated shares of the total indirect cost for the period based
on their usage as measured by the cost driver.

capitalization of costs

When a cost is recorded originally as an increase
to an asset account, it is said to be capitalized. This means that the outlay
is treated as a capital expenditure, which becomes part of the total
cost basis of the asset. The alternative is to record the cost as an expense
immediately in the period the cost is incurred. Capitalized costs refer
mainly to costs that are recorded in the long-term operating assets of a
business, such as buildings, machines, equipment, tools, and so on.

conversion cost

Refers to the sum of manufacturing direct labor and overhead
costs of products. The cost of raw materials used to make products
is not included in this concept. Generally speaking, this is a rough measure
of the value added by the manufacturing process.

cost of capital

Refers to the interest cost of debt capital used by a business
plus the amount of profit that the business should earn for its equity
sources of capital to justify the use of the equity capital during the
period. Interest is a contractual and definite amount for a period,
whereas the profit that a business should earn on the equity capital
employed during the period is not. A business should set a definite goal
of earning at least a certain minimum return on equity (ROE) and compare
its actual performance for the period against this goal. The costs of
debt and equity capital are combined into either a before-tax rate or an
after-tax rate for capital investment analysis.

fixed expenses (costs)

Expenses or costs that remain the same in amount,
or fixed, over the short run and do not vary with changes in sales volume
or sales revenue or other measures of business activity. Over the
longer run, however, these costs increase or decrease as the business
grows or declines. Fixed operating costs provide capacity to carry on
operations and make sales. Fixed manufacturing overhead costs provide
production capacity. Fixed expenses are a key pivot point for the analysis
of profit behavior, especially for determining the breakeven point and for
analyzing strategies to improve profit performance.

overhead costs

Overhead generally refers to indirect, in contrast to direct,
costs. Indirect means that a cost cannot be matched or coupled in any
obvious or objective manner with particular products, specific revenue
sources, or a particular organizational unit. Manufacturing overhead
costs are the indirect costs in making products, which are in addition to
the direct costs of raw materials and labor. Manufacturing overhead
costs include both variable costs (electricity, gas, water, etc.), which vary
with total production output, and fixed costs, which do not vary with
increases or decreases in actual production output.

product cost

This is a key factor in the profit model of a business. Product
cost is the same as purchase cost for a retailer or wholesaler (distributor).
A manufacturer has to accumulate three different types of production
costs to determine product cost: direct materials, direct labor, and
manufacturing overhead. The cost of products (goods) sold is deducted
from sales revenue to determine gross margin (also called gross profit),
which is the first profit line reported in an external income statement
and in an internal profit report to managers.

sunk cost

A cost that has been paid and cannot be undone or reversed.
Once the cost has been paid, it is irretrievable, like water over the dam
or spilled milk. Usually, the term refers to the recorded value of an asset
that has lost its value in the operating activities of a business. Examples
are the costs of products in inventory that cannot be sold and fixed
assets that are no longer usable. The book value of these assets should
be written off to expense. These costs should be disregarded in making
decisions about what to do with the assets (except that the income tax
effects of disposing of the assets should be taken into account).

weighted-average cost of capital

Weighted means that the proportions of
debt capital and equity capital of a business are used to calculate its
average cost of capital. This key benchmark rate depends on the interest
rate(s) on its debt and the ROE goal established by a business. This is a
return-on-capital rate and can be applied either on a before-tax basis or
an after-tax basis. A business should earn at least its weighted-average
rate on the capital invested in its assets. The weighted-average cost-ofcapital
rate is used as the discount rate to calculate the present value
(PV) of specific investments.
