The percent-of-sales method is a frequently encountered simple approach for estimating cost components and profits in projected income statements. The method assumes that all costs are variable, implying that profit margin is constant. Profit margin ratios are also used to estimate profits directly. This may be reasonable in the long run, but some fixed costs are present in the short-run, resulting in forecast errors. I propose a short equation that incorporates the initial profit margin, the sales growth rate, and the ratio of fixed cost to initial sales that renders more accurate profit estimates while preserving the simplicity of the method.

The most effective way to generate an estimate of a new product’s cost engineering change cost, or innovation cost is through a detailed cost investigation. Analysis of the available materials and processes leads to the most economical and financial decisions. Now in its third edition, Realistic Cost Estimating for Manufacturing has been used by students and practitioners since 1968 in this endeavor. Revised and expanded, the book recognizes the extremely important role estimating is playing in today’s highly competitive global economy. Realistic Cost Estimating for Manufacturing provides a survey of the myriad manufacturing processes and practices and combines this with in-depth explanations and examples of costing methods and tools. A comprehensive, standardized approach to their application is given. Among the manufacturing processes surveyed are: machining, casting, stamping, forging, welding, plastics technology, finishing, and rapid prototyping. To develop realistic baseline estimates, an engineering or costing professional must have an in-depth understanding of costing methods and techniques. As a fundamental reference, the book provides insight into the art, science, and functions of cost estimation in a wide range of activities: product design and manufacturing, engineering change control, proposal development, make or buy studies, identifying cost reduction opportunities, component costing, reverse engineering, benchmarking, and examining alternative processes, materials, machines, and tooling. As examples, it will aid the practitioner in efforts to justify the replacement or improvement of existing technology with new creative solutions; perform a feasibility study; develop a basis for cost-oriented decision support; improve supply chain evaluation and sourcing analysis; and minimize costs. The third edition has been greatly enhanced with new chapters and material dedicated to the roles of economics and finance, cost reduction, continuous improvement, plastic parts, electronics cost estimating, costing studies, advanced manufacturing processes, and quality costs. Further, the existing chapters have been significantly expanded to include new processes and operations and examples to enhance learning. Since nontraditional technology is widely applied in manufacturing, its costing aspects are also explored. Five Appendices provide additional information on productivity based on efficiency, cost reduction, matching part features to manufacturing processes, packaging cost, and inspection and measurement costs. As with its previous editions, instructors of cost estimating courses can rely on the book to provide a solid foundation for manufacturing engineering courses and programs of study. The book is also useful for on-the-job training courses for engineers, managers, estimators, designers, and practitioners. It can be applied in seminars and workshops specifically dedicated to product or component cost reduction, alternative cost analysis, engineering change cost control, or proposal development. As in the previous editions, there are multiple equations and calculation examples, as well as end-of-chapter questions to test student’s knowledge. An instructor’s guide is also available.

In order to succeed in a construction business you have to be able to mark up the price of your jobs to cover overhead expenses and make a decent profit. The problem is how much to mark it up. You don't want to lose jobs because you charge too much, and you don't want to work for free because you've charged too little. If you know how much to mark up you can apply it to your job costs and arrive at the right sales price for your work. This book gives you the background and the calculations necessary to easily figure the markup that is right for your business. Includes a CD-ROM with forms and checklists for your use.

The authors present the latest principles and techniques for the evaluation of engineering design. The text is suitable for undergraduate or graduate courses in cost estimating in engineering, management and technology settings.
