In order to calculate discount rate, there are various methods that have been used such as the weighted average cost of capital (WACC) and the capital asset pricing model (CAPM), hurdle rate method and Gordon model. Time duration (n) of the discount factor expresses the expected period of the future cash flows.

For financial accounting purposes, the discount factor has been useful in many ways. In preparing the financial statements, future cash flows cannot be included mainly because of the revenue recognition principle and the cost principle. According to those principles, all the transactions must be recorded with their exact cash values at the time of which the transaction takes place. In order to adhere to those principles, the discount factor has been used by the accountants to find the present value of the future cash flows and that value has been recorded in the financial statements at the time of the transaction.

The present value of the future cash flows can be calculated using the below formula:

Therefore, these changes may have an impact on the calculated financial figures. Further, the time is also an unpredictable factor as unexpected incidents may have a negative impact on the projects future cash flows.
