Advantages of Internal Rate of Return Method
A brief explanation of advantages of Internal Rate of Return method is presented below.
1. It considers the time value of money even though the annual cash inflow is even and uneven.
2. The profitability of the project is considered over the entire economic life of the project. In this way, a true profitability of the project is evaluated.
3. There is no need of the pre-determination of cost of capital or cut off rate. Hence, Internal Rate of Return method is better than Net Present Value method.
4. Sometimes, the pre-determination of cost of capital is very difficult. At that time, Internal Rate of Return can be used to evaluate the project.
