The different investment analysis approaches require various interest formulas and their values. A fairly large problem involving different types of transactions in its cash-flows may take more time to solve it, if the students compute the values of the related interest formulas and then make substitutions in the respective expressions of the investment analysis. This book gives values of different interest factors, (F/P,i,n), (P/F,i,n), (F/A,i,n), (A/F,i,n), (P/A,i,n), (A/P,i,n) and (A/G,i,n) for different combinations of interest rate (i) and interest period (n) in the form of tables, to serve as an aid for solving problems in "Engineering Economics" in the examination hall. These Interest Tables can also be usefully employed for field work while doing engineering economics analysis.The tables will be useful to students of different B.Tech. programmes and to students of M.Com and M.B.A. programmes for solving different investment analysis problems
