Comparative Annual Costs

Abstract : Comparative annual costs offers a simple and exact method of comparing costs of capital investment alternatives. It allows for interest and can be used for a single piece of equipment or for an entire plant. Differences in first cost, service life, operating expense, deterioration and obsolence cost, and salvage value are accounted for, and there is no limit to the items which can be considered. The calculations are readily made with only two tabulated factors. Comparative annual costs can be applied as either a quick evaluation of equipment investment alternatives or a formal method of machine tool replacement analysis. (Author)
