The discount factor, DF(T), is the factor by which a future cash flow must be multiplied in order to obtain the present value. For a zero-rate (also called spot rate) r , taken from a yield curve , and a time to cash flow T (in years), the discount factor is:
The concept of the stochastic discount factor (SDF) is used in financial economics and mathematical finance. The name derives from the price of an asset being computable by "discounting" the future cash flow x ~ i {\displaystyle {\tilde {x}}_{i}} by the stochastic factor m ~ {\displaystyle {\tilde {m}}} , and then taking the expectation.

The utility of an event x occurring at future time t under utility function u, discounted back to the present (time 0) using discount factor β, is (). Since more distant events are less liked, 0 < β < 1.
The accuracy of the NPV method relies heavily on the choice of a discount rate and hence discount factor, representing an investment's true risk premium. [15] The discount rate is assumed to be constant over the life of an investment; however, discount rates can change over time. For example, discount rates can change as the cost of capital ...
Calculating the net present value, , of a stream of cash flows consists of discounting each cash flow to the present, using the present value factor and the appropriate number of compounding periods, and combining these values. [1]

MedICT has chosen the perpetuity growth model to calculate the value of cash flows beyond the forecast period.

Expression (3) which uses the bond's yield to maturity to calculate discount factors. The key difference between the two durations is that the Fisher–Weil duration allows for the possibility of a sloping yield curve, whereas the second form is based on a constant value of the yield y {\displaystyle y} , not varying by term to payment.
