Engineering Economy Terminology Amortization  As applied to a capital asset, the distribution of the initial cost by periodic charges to operations as in depreciation. Most property applies with indefinite life  The reduction of a debt by either periodic or irregular payments  A plan to pay off a financial obligation according to some prearranged program.  Annual Equivalent  In time value of money, a uniform annual amount for a prescribed number of years that is equivalent in value to the present worth of any sequence of financial events for a given interest rate.  One of a sequence of equal end-of-year payment which would have the same financial effect when interest is considered as another payment or sequence of payments which are not necessarily equal in amount or equally spaced in time.  Annuity  An amount of money payable to a beneficiary at regular intervals for a prescribed period of time out of a fund reserved for that purpose.  A series of equal payments occurring at equal period of time.  Annuity Fund  A fund that is reserved for payment of annuities. The present worth of funds required to support future annuity payments.  Asset  An accounting term for capital owned by a company.  Book Value  The recorded current value of an asset. First cost less accumulated depreciation, amortization, or depletion.  Original cost of an asset less the accumulated depreciation  The worth of a property as shown on the accounting records of a company. It is ordinarily taken to mean the original cost of operations less the amounts that have been charged as depreciation expense.  Breakeven Chart  A graphical representation of the relation between total income and total costs for various levels of production and sales indicating areas of profit and loss.  Breakeven point  In business operations, the rate of operations, output, or sales at which income is sufficient to equal operating cost, or operating cost plus additional obligations that may be specified.  The operating condition, such as output, at which two alternatives are equal in economy.  The percentage of capacity operation of a manufacturing plant at which income will just cover expenses.  Capacity Factor  The ratio of average load to maximum capacity  The ratio between average load and the total capacity of the apparatus, which is the optimum load.  The ratio of the average actual use to the available capacity.  Capital  The financial resources involved in establishing and sustaining an enterprise or project.  A term describing wealth that may be utilized to economic advantage. The form of this wealth takes may be as cash, land, equipment, patents, raw materials, finished products, etc.  Capital Recovery  Charging periodically to operations amounts that will ultimately equal the amount of capital expenditures.  The replacement of the original cost of an asset plus interest.  The process of regaining the net investment in a project by means of revenue in excess of the cost from the project. (Usually implies amortization of principal plus interest on the diminishing un- recovered balance.)  Capital Recovery Factor  A factor used to calculate the sum of money required at the end of each of a series of periods to regain the net investment of a project plus the compounded interest on the unrecovered balance.  Capitalized Cost  The present worth of a uniform series of periodic costs that continue for an indefinitely long time (hypothetically infinite). Not to be confused with a capitalized expenditure.  The value of the purchase date of the first life of the asset of all expenditures to be made in reference to this asset over an infinite period of time. This cost can also be regarded as the sum of capital which, if investment in a fund earning a stipulated interest rate, will be sufficient to provide for all payments required to maintain the asset in perpetual service.  Cash Flow  The flow back pf profit plus depreciation from a given project.  The actual dollars passing into and out of the treasury of a financial venture.  Common Costs  Costs that cannot be identified with a given output of products, operations, or services.  Compound Amount  The future worth of a sum invested (or loaned) at compound interest.  Combined Interest Rate  The cost of capital, expressed as an effective rate (percent) per interest period, including, a market adjustment for the anticipated general price inflation rate in the economy. Thus, it represents the time value change in future cash flows and takes into account both the potential real earning power of money and the estimated general price inflation in the economy.  Compound Amount Factor  The function of interest rate and time that determines the compound amount from a stated initial sum.  A factor which when multiplied by the single sum or uniform series of payments will give the future worth at compound interest of such single sum or series.  Compound Interest  The type of interest that is periodically added to the amount of investment (or loan) so that subsequent interest is based on the cumulative amount.  The interest charges under the condition that interest is charged on any previous interest earned in any time period, as well as on the principal.  Compounding, Continuous  A compound interest situation in which the compounding period is zero and the number of periods infinitely great. A mathematical concept that is practical for dealing with frequent compounding and small interest rates.  A mathematic procedure for evaluating compound interest factors based on a continuous interest function rather than discrete interest period.  Compound Period  The time interval between dates at which interest is paid and added to the amount of an investment or loan. Designates frequency of compounding.  Decision Period  A program of action undertaken as a result of established policy to influence the final decision.  Decisions Under Certainty  Simple decisions that assume complete information and no uncertainty connected with the analysis of the decisions.  Decisions Under Risk  A decision problem in which the analyst elects to consider several possible futures, the probabilities of which can be estimated.  Decisions Under Uncertainty  A decision for which the analyst elects to consider several possible futures, the probabilities of which cannot be estimated.  Declining Balance Depreciation, also known as percent on diminishing value  A method of computing depreciation in which that annual charge is fixed percentage of the depreciated book value at the beginning of the year to which the depreciation applies.  Demand Factor  The ratio of the maximum instantaneous production rate to the production rate for which the equipment was designed.  The ratio between the maximum power demand and the total connected load of the system.  Depletion  A form of capital recovery applicable to extractive property (example, mines). Can be a unit-of- output basis the same as straight-line depreciation related to original or current appraisal of extent and value of deposit (known as cost depletion). Can also be a percentage of income received from extractions (known as percentage depletion).  A lessening of the value of an asset due to a decrease in the quantity available. It is similar to depreciation except that it refers to such natural resources as coal, oil, and timber in forests.  Depreciated Book Value  The first cost of the capitalized asset minus the accumulation of annual depreciation cost charges.  Depreciation  Decline in value of a capitalized asset  A form of capital recovery applicable to a property with two or more years’ life span, in which an appropriate portion of the asset’s value is periodically charged to current operations.  The loss of value of obsolescence or due to attrition. In accounting, depreciation is the allocation of this loss of value according to some plan.  Differential Price Inflation Rate  The percentage increment of price change (in the unit price, or cost for fixed amount), above or below the general price inflation rate, during a time period for goods or services.  Discounted Cash flow  The present worth of a sequence in time of sums of money when the sequence is considered as a flow of cash into and/or out of an economic unit.  An investment analysis that compares the present worth of projected receipts and disbursements occurring at designated future times in order to estimate the rate of return from the investment or project.  Earning Value  The present worth of an income producer’s probable future net earnings, as prognosticated on the basis of recent and present expense and earnings and the business outlook.  Economic good  Anything that is useful, transferable, and not abundant.  Economic Model  A mathematical expression or tabular relation that expresses the interaction of technical and economic variables applying to a specific problem.  Economic Return  The profit derived from a project or business enterprise without consideration of obligations to financial contributors and claims of other based on profit.  Economy  The cost or profit situation regarding a practical enterprise or project, as in economy study, engineering economy, engineering economic analysis.  Effective Interest  The true value of interest rate computed by equations for compound interest for 1-year period.  Endowment  A fund established for the support of some project or succession of donations or financial obligations.  Engineering economy  The application of engineering or mathematical analysis and synthesis to economic decisions  A body of knowledge and techniques concerned with the evaluation of the worth of commodities and services relative to their cost  The economic analysis or engineering alternatives.  Estimate  The true magnitude as closely as it can be determined by the exercise of sound judgment based on approximate computations; not to be confused with offhand approximations that are little better than outright guesses.  Expected return  The profit participated from a venture.  Expected Yield  The ratio expected return/investment, usually expressed as a percentage on an annual basis.  Expense  Synonymous with cost for purposes of these terminologies.  First Cost  The initial cost of a capitalized property, including transportation, installation, preparation for service, and other related initial expenditures.  Future Worth  The equivalent value at a designated future date based on time value of money  The monetary sum, at a given future time, which is equivalent to one or more sums at given earlier times when interest is compounded at a given rate.  General Price Inflation Rate  A general measure of the change in the purchasing power of dollar or peso during a specified period of time.

It is a cost, already paid, that is not relevant to the decision concerning the future that is being made. Capital already invested that for some reason cannot be retrieved.  A past cost that has no relevance with respect to future receipts and disbursements of a facility undergoing an engineering economy study. This concept implies that since a past outlay is the same regardless of the alternative selected, it should not influence the choice between alternatives.  Tangibles  Things that can be quantitatively measured or valued, such as items of cost and physical assets.  Time Value of Money  The cumulative effect of elapsed time on the money value of an event, based on the earning power equivalent invested funds.  The expected interest rate that capital should or will earn.  Total Price Escalation Rate  The total rate (%) of price change (in unit price, or cost for a fixed amount) during a time period for good or service.  The total price escalation rate for a good or service includes the effects of both the general price inflation rate and the differential price inflation on price changes. The rate is projected for a future time interval and usually expressed as an effective annual rate.  Traceable Costs  Costs which ca be identified with a given product, operation, or service.  Unrecovered Investment Balance  The investment amount outstanding in a venture, allowing for profits generated and including the time value of money.  Valuation or Appraisal  The art of estimating the fair-exchange value of specific properties.  Working Capital  That portion of investment represented by current assets (assets that are not capitalized) less the current liabilities.
