Compounding and discounting
The process of calculating future values = compounding, ie the sum of beginning amount and the interest earned. The process of finding out the present value = discounting ie the inverse of compounding. Basically for a single cash flow: F = P [F/P, i%, N] F = P (1+i)N !!! The following are the cases for discrete compounding and discrete cash flow. Case 1.
Benefit to Cost Ratio (B/C or BCR):
B/C ratio is defined as the ratio of equivalent worth of benefit to the equivalent worth of cost. Equivalent worth may be either Present worth (Pw), Annual worth (Aw) or Future worth (Fw). Benefit to Cost ratio is also known as Profitability Index (PI) being the indicator of the profit. Types of B/C Ratio: Conventional BCR Modified BCR Decision: The project is economically feasible only if B/C ? 1 B/C Ratio formulae: Methods Conventional B/C Modified B/C Pw method     Aw method     Fw method     Here, I = ...
Break Even Analysis (BEA)

Payback Period
The period of time required to recover the net investment is called payback period, PB. The project which pays back the initial investment in the smallest period is acceptable under this method. Decision: If (calculated PB < standard  PB) => Accept the project If (calculated PB > standard  PB) => Reject the project Merits of payback period: ü  Easy to understand and inexpensive to use. ü  Easy and crude way to analyze the risk. ü  ...
Social Cost Benefit Analysis SCBA vs Cost Benefit Analysis CBA

Economic Variances in Engineering Economics
Types of Economic Variances There are mainly 4 types of variances in engineering economics, namely Direct material cost variance Direct wages/labor cost variance Variable overhead variance Fixed overhead variance Negative (-) variance is always favorable ie actual cost (-) << standard cost (+). 1. Direct material cost variance This is the difference between standard cost of direct material specified for the o/p and the actual cost of direct materials used.
