An NPV calculated using variable discount rates (if they are known for the duration of the investment) may better reflect the situation than one calculated from a constant discount rate for the entire investment duration. Refer to the tutorial article written by Samuel Baker [9] for more detailed relationship between the NPV and the discount rate.
In finance, risk-adjusted net present value (rNPV) or expected net existing value (eNPV) is a method to value risky future cash flows. rNPV is the standard valuation method in the drug development industry, [1] where sufficient data exists to estimate success rates for all R&D phases. [2]
Using DCF analysis to compute the NPV takes as input cash flows and a discount rate and gives as output a present value. The opposite process takes cash flows and a price (present value) as inputs, and provides as output the discount rate; this is used in bond markets to obtain the yield.
Only negative cash flows — the NPV is negative for every rate of return. (−1, 1, −1), rather small positive cash flow between two negative cash flows; the NPV is a quadratic function of 1/(1 + r), where r is the rate of return, or put differently, a quadratic function of the discount rate r/(1 + r); the highest NPV is −0.75, for r = 100%.

MedICT has chosen the perpetuity growth model to calculate the value of cash flows beyond the forecast period.
The method is to calculate the NPV of the project as if it is all-equity financed (so called "base case"). [7] Then the base-case NPV is adjusted for the benefits of financing. Usually, the main benefit is a tax shield resulted from tax deductibility of interest payments. [7] Another benefit can be a subsidized borrowing at sub-market rates.
The interest rates per period might not be the same. The cash flow must be discounted using the interest rate for the appropriate period: if the interest rate changes, the sum must be discounted to the period where the change occurs using the second interest rate, then discounted back to the present using the first interest rate.

Bond valuation is the process by which an investor arrives at an estimate of the theoretical fair value, or intrinsic worth, of a bond.As with any security or capital investment, the theoretical fair value of a bond is the present value of the stream of cash flows it is expected to generate.
