A i ( n 1 + i ) − 1 = A i = periodic payment (end of period) , F , i , n as above for compound interest

INFLATION f, and then they are shifted over the time scale using the interest rate per interest period iq computing present worth values P and Net P The formula for d is d i + f + (i × f)

An end-of-period cash receipt or disbursement in a uniform series continuing for n periods. Uniform period-by-period increase or decrease in cash receipts or disbursements. Uniform rate of cash flow increase or decrease from period to period; the geometric gradient. Nominal interest rate per interest period. Number of compounding subperiods per period.

EECE 450 — Engineering Economics — Formula Sheet Cost Indexes: Ordinary Geometric Gradient Annuity: Cost at time A Index value at time A = Cost at time B Index value at time B 1 − (1 + g ) n (1 + i ) − n P = A1 ; i ≠ g i−g Power sizing: Cost of asset A Size (capacity) of asset A =

This document provides formulas and definitions for various engineering economic calculations. It defines terms like present worth, future worth, uniform series, sinking fund, capital recovery, depreciation, inflation, bonds, rate-of-return, benefit-cost analysis, and break-even analysis.

Steps to solution Step 1: Identify cash flow (P and F) Step 2: Identify interest rate (i) and number of periods Step 3: Select appropriate table or formula F=P(1+i)n P=F(1+i)-n F=P(F/P,i,n) P=F(P/F,i,n) Step 4: Perform calculation All four steps are …

Texts on engineering economics also present formulas for a series of increasing (or decreasing payments) where the rate of increase (or decrease) is the same and the payment interval is constant.

There are two cash flows to each problem (borrower and lender flows). nNet cash flow: The arithmetic sum of receipts (+) and disbursements ( -) that occur at the same point in time.
