The preparation and analysis of development projects require much computation - of internal rates of return, benefit-cost ratios, net present worth, and rates of growth. For these and many other calculations, project planners and analysts will find this book a convenient and time-saving reference. Six-decimal tables for 1 percent through 50 percent show the compounding factor for 1 and for 1 per annum, the sinking fund factor, the discount factor, the present worth of an annuity factor, and the capital recovery factor. Summary present worth tables give project analysts at a glance the discount factors most used to calculate measures of project worth. Narrow-interval compounding tables give the compounding factor for 1 at fractional interest rates from 0.0 through 20.9 percent. All tables give values for project years 1 through 50. This new edition sets out the same careful and practical methodology for analyzing agricultural investments but adds a wealth of recent project data, expanded treatment of farm budgets and efficiency prices, appendixes on presenting project preparation reports and on using discounting tables, an expanded and completely annotated bibliography, and a detailed glossary of technical terms.
