This printed book (8.5 x 11 in.) is a comprehensive set of discount factor tables useful to the ASTM practices for economic evaluations of buildings. Three sets of tables are presented. The first includes single-payment and uniform-series discount factors. The second presents uniform present value factors for a series of payments increasing from period to period at a given rate. The third presents single present value factors for determining the present value of a single payment occurring at a future point in time.
