The NPV method can be slightly adjusted to calculate how much money is contributed to a project's investment per dollar invested. This is known as the capital efficiency ratio. The formula for the net present value per dollar investment (NPVI) is given below:
Net present value makes it easier to compare investments by distinguishing cash inflows and costs. In terms of the advantages or benefits of applying the NPV formula, it’s easy to calculate if ...
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
Determination of the after-tax NPV of the investment; Calculation of the after-tax NPV of the operating cost stream; Applying a sinking fund amortization factor to the after-tax amount of any salvage value. In mathematical notation, for assets subject to the general half-year rule of CCA calculation, this is expressed as:
However, NPV calculations require additional sophistication including maintenance of a discount rate, which leads most organizations to instead calculate CLV using the nominal (non-discounted) figures. Nominal CLV predictions are biased slightly high, scaling higher the farther into the future the revenues are expected from customers.
When NPV demonstrates a positive value, it indicates that the project is expected to generate value. Conversely, if NPV shows a negative value, the project is expected to lose value. In essence, IRR signifies the rate of return attained when the NPV of the project reaches a neutral state, precisely at the point where NPV breaks even. [4]
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 .
Equivalently C is the periodic loan repayment for a loan of PV extending over n periods at interest rate, i. The formula is valid (for positive n, i) for ni≤3. For completeness, for ni≥3 the approximation is . The formula can, under some circumstances, reduce the calculation to one of mental arithmetic alone.
