Traditional methods or Non-Discounted method


1Net Present Value method

3 Rate of return method or accounting method


Time-adjusted method or discounted methods


(i) Net Present Value method


(ii) Internal Rate of Return method


(iii)Profitability Index method


1 Pay-back period method


This method represent the period in which total investment in permanent asset pays back itself. It measure the period of time for the original cost of a project to be recovered from the additional earning of a project itself.


Investment are ranked according to the length of the payback period, investment with shorter payback period is preferred.


How the payback period is calculated?



The payback period is ascertained in the following manner


·                    Calculate annual net earnings(profit) before depreciation and after taxes, these are called annual cash inflow


·                    Divide the initial outlay(cost) of the project by the annual cash inflow, where the project generates constant annual cash inflow


Payback period = cash outlay of the project or original cost of the asset

Annual cash inflows

·        Where the annual cash inflows (profit before depreciation and after taxes) are unequal the


payback period is found by adding up the cash inflows until the total is equal to the initial cash outlay of the project.


Selection criterion

Improvement of Traditional Appraoch To Payback Period:


Payback Reciprocal Method


Discounted payback period : - (time value of money in consider)



v   It is a simple method to calculate and understand


v   It is a method in terms of years for easier appraisal



v   It is a method rigid


v   It has completely discarded the principle of time value of money


v   It has not given any due weight age to cash inflows after the payback period


v   It has sidelined the profitability of the project.


2 Average Rate of Return method (ARR)


This method takes in to account the earnings expected from the investment over their whole life. It is known as accounting rate of return.


The project which gives the higher rate of return is selected when compared to one with lower rate of return.


Selection criterion of the projects:



v   It is simple method to compute the rate of return


v   Average return is calculated from the total earnings of the enterprise through out the life of the firm


v   The entire rate of return is being computed on the basis of the available accounting data




v   Under this method, the rate of return is calculated on the basis of profits extracted from the books but not on the basis of cash inflows


v   The time value of money is not considered


v   It does not consider the life period of the project


v   The accounting profits are different from one concept to another which leads to greater confusion in determining the accounting rate of return of the projects


3 Net present value method(NPV)


It is a modern method of evaluating investment proposals. It takes into consideration time value of money and calculates the return on investment by introducing the factor of time element.


v        First determine the rate of interest that should be selected as the minimum required rate of return

v        Compute the present value of total investment outlay


v        Compute the present value of total cash inflows


v        Calculate Net Present Value by subtracting the present value of cash inflow by present value of cash outflow.


v        NPV = is positive or zero the project is accepted



v        NPV= is negative then reject the proposal


v        In order for ranking the project the first preference is given to project having maximum positive net present value


NPV= Present value of cash inflow – present value of cash outflow/Initial investment Selection criterion of Net present value method


4 Internal Rate of Return Method (IRR)


Under the internal rate of return method, the cash flows of a project are discounted at a suitable rate by hit and trial method, which equates the net present value so calculated to the amount of investment.


v        Determine the future net cash flows during the entire economic life of the project. The cash inflows are estimated for future profits before depreciation but after taxes


v        Determine the rate of discount at which the value of cash inflow is equal to the present value of cash outflows


v        Accept the proposal if the internal rate of return is higher than or equal to the cost of capital or cut off rate.

v        In case of alternative proposals select the proposal with the highest rate of return.


5 Profitability index method or Benefit cost Ratio (P.I)


It is also called Benefit cost ratio is the relationship between present value of cash inflow and present value of cash outflow

The proposal is accepted if the profitability index is more than one and is rejected the profitability index is less than one


The various projects are ranked; the project with higher profitability index is ranked higher than other.




Profitability Index Method (or) Benefit cost Ratio: -
