What is the difference between payback period and discounted payback period?

The payback period and discounted payback period are both methods used in capital budgeting to evaluate the profitability and feasibility of investment projects. However, they differ in terms of the time value of money consideration.

The payback period is a simple method that calculates the time required for an investment to recover its initial cost. It is calculated by dividing the initial investment by the annual cash inflows generated by the project. The payback period is expressed in years or months and represents the time it takes for the project to generate enough cash flows to recover the initial investment.

On the other hand, the discounted payback period takes into account the time value of money by discounting the future cash flows to their present value. This method recognizes that a dollar received in the future is worth less than a dollar received today due to factors such as inflation and the opportunity cost of capital. The discounted payback period calculates the time required for an investment to recover its initial cost, considering the discounted cash flows.

To calculate the discounted payback period, the future cash flows are discounted using an appropriate discount rate, such as the project's cost of capital or the required rate of return. The discounted cash flows are then accumulated until they equal or exceed the initial investment. The discounted payback period is also expressed in years or months, representing the time it takes for the project to recover the initial investment when considering the time value of money.

The main difference between the payback period and discounted payback period is that the payback period does not consider the time value of money, while the discounted payback period does. By incorporating the time value of money, the discounted payback period provides a more accurate measure of the project's profitability and risk. It considers the present value of future cash flows, allowing decision-makers to assess the project's viability in terms of its ability to generate returns that exceed the cost of capital.

In summary, the payback period and discounted payback period are both useful tools in capital budgeting. The payback period provides a simple measure of the time required to recover the initial investment, while the discounted payback period considers the time value of money by discounting the future cash flows. The choice between these methods depends on the specific needs and preferences of the decision-makers, as well as the importance given to the time value of money in the evaluation process.
