WitrynaNominal and effective interest rates Effective interest rate, i P, (period of compounding=period of interest) is used in formulas: i=i P=(1+ i s)m-1 i=i P=(1+r P/m)m-1 i s=interest per subperiod m=number of subperiods in period P r P=nominal interest per period P Nominal interest rate, r P=m X i s =e) n = P* WitrynaThe purpose of engineering economy calculations is equivalence in PW or AW terms for a stated i ≥ 0%. In rate of return calculations, the objective is to find the interest rate i* at which the cash flows are equivalent. The calculations are the reverse of those made in previous chapters, where the interest rate was known.
