Present value of net benefits

In considering either multiple payments or cash into and out of a company, the present values are additive. For example, at 6 percent interest, the present value of receiving both 1,000 in one year and 1,000 in three years would be 943.40 + 839.62 = 1,783.06. Similarly, if one were to receive 1,000 in one year, and pay 1,000 in 3 years the present value would be 943.40 - 839.62 = 103.78. It is common practice to compare investment options based on the present-value equation shown above. We may also apply one or all of the following four factors when comparing investment options Payback Period Internal Rale of Return Benefit-to-cost Ratio and Present Value of Net Benefit. But as we will see later, it is rate of return that is usually the most enlightening when considering an investment. 

It is eommon praetice to eompare investment options based on the present-value equation shown above. We may also apply one or all of the following four factors when comparing investment options Paybaek period Internal rate of return Benefit-to-cost ratio and Present value of net benefit.

The present values of the benefits and costs are kept separate, and expressed in one of two ways. First, there is the pure B/C ratio, which implies that if the ratio is greater than unity, the benefits outweigh the costs and the project is viable. Second, there is the net B/C ratio, which is the net benefit (benefits minus costs) divided by the costs. In this latter case, the decision criterion is that the benefits must outweigh the costs, which means that the net ratio must be greater than zero (if the benefits exactly equaled the costs, the net B/C ratio would be zero). In both cases, the highest B/C ratios are considered as the best projects. 

The net present value is defined as the difference between the present values of the benefits and tbe costs of the project. 

The use of controllers may also reduce over-all expenses. The average operator in a chemical plant, when fringe benefits are included, costs the company over 5.00 per hour. This is equivalent to 43,800 per year for an operating position. By the methods given in Chapters 10 and 11, this can be shown to be equivalent to a net present value of - 320,000 (assumes money is valued at 8%). The average controller, installed, costs between 3,000 and 6,000. This means that a large number... 

The Net Present Value (NPV) of a capital investment is the equivalent total cash flow generated by all the acquisition s benefits less all the acquisition s costs computed over the life of the system on a year to year basis, adjusted for the value of money as reflected by such factors as finance rates, and projected ("discounted") to the present day. A dollar benefit projected for the system next year would only be worth 0.91 today if that dollar could be earning 10% interest. A net present value of zero means that the acquisition will, over its projected life, just break even and that it is therefore an acceptable purchase. A better than zero NPV would be a high priority purchase since it indicates a real profit. 

The Internal Rate of Return (IRR) is the equivalent interest rate at which the Net Present Value of the acquisition would be zero. Given the projected total cost of the system, and the projected total benefits of the system, both projected back (discounted) to today, it is the interest rate that the investment could sustain and still just break even. Since firms, in general, operate at a point where their incremental cost of money is equal to its incremental earning power, any investment that returns an IRR better than the cost of money is a good investment. Traditionally, the IRR is found by calculating the NPV with different interest factors in a trial and error method until the interest factor is found which drives the NPV to approximately zero. 

The fourth stage of the methodology compares the expected present value of the total social cost savings to the present value of the R D expenditures required to realize the innovation. Ratios, such as the net benefit to government R D cost ratio, can be used to compare the worth of various alternative projects. 

The tangible costs and benefits are then used to determine the viability of the project. Typictdly, this involves determining the net present value (NPV) of the system. Since the cost of developing the system is incurred before the systems begins to generate value for the organization over the life of the system, it is necessary to discount the future revenue streams to determine whether the project is worth undertaking. The present value of anticipated costs at a future point in time is determined by ...

Finance. The management of money in the United States is simplistic compared to what countries with high inflation rates or huge recessions face. In addition, the methodology of accruing funding can be quite complex. Tools such as Net Present Value and Cost/Benefit analysis can help you evaluate a financially valid course of action. 

Although the reasoning seems sound, opportunity costs are not really expenses. Though it is true that the cash will be unavailable for other investments, opportunity cost should be thought of as a comparison criteria and not an expense. The opportunity forgone by using the cash is considered when the project competes for funds and is expressed by one of the financial analysis factors discussed earlier (net value of present worth, pay back period, etc.). It is this competition for company funds that encompasses opportunity cost, so opportunity cost should not be accounted directly against the project s benefits. 

Capital investment decisions are best made within the context of a life-cycle cost analysis. Life-cycle cost analysis focuses on the costs incurred over the life of the investment, assuming only candidate investments are considered that meet minimally acceptable performance standards in terms of the non-inonetary impacts of the investment. Using life-cycle analysis, the capital investment decision takes into account not just the initial acquisition or purchase cost, but maintenance, energy use, the expected life of the investment, and the opportunity cost of capital. When revenue considerations are prominent, an alternative method of analysis such as net benefit or net present value may be preferred. 

Once values have been assigned for the costs and benefits of each proposed risk-reduction modification, a variety of economic evaluation techniques may be used to choose the most attractive option. These techniques include net present value, discounted cash flow rate of return and cost-benefit ratio analyses. Most companies have a preferred method for evaluating project economics, which can be used with little or no modification. Chapter 8 of... 

In general, one or more of three methods are used to justify major expenditures. The first, payback, is a measure of the time it will take for cumulative benefits to equal cumulative costs (time to break even). This, by itself, may not be sufficient to compare alternative investments and projects competing for the same limited resources so one of two other methods may be used. These methods, Net Present Value and Internal Rate of Return, consider the earning power of money in making comparisons. Because investments earn compound interest, a dollar to be gained in the future has less present value than one gained today. The NPV is computed by estimating the yearly... 

Step 1 Business value assessment Identify and quantify the business value for the proposed new method or analyzer. This is done jointly by the customer and the project manager. Ideally the value of the technology can be expressed concretely in monetary terms (e.g. dollars) as, for example, a net present value (NPV) or an internal rate of return (IRR). It is critical to include a realistic estimate of the costs of implementing and maintaining the analyzer, as weU as the benefits to be realized from it. This assessment is used to prioritize effort and expenses and to justify any capifal purchases needed. The various ways that process analyzers can connibute to business value are discussed in Section 15.2.2. 

ROA), index of profitability (IP), initial rate of return (IRR) and net present value (NPV) are often used to estimate the benefit of capital projects including those of PA nature. NPV is represented by the equation... 

Once aU the costs (and savings) associated with each solution are identified, financial tools for rating investments, familiar to many businesses, are then used to evaluate the economic added value of each option net present value (NPV), internal rate of return (IRR) and payback period. Additionally, C02-equivalent savings are assessed to identify environmental benefits of each solution. 

ABSTRACT The increased use of wireless networks in schools has created concern among many parents and scientists is the low levels microwave radiation emitted by the transmitters harmful The scientific community does not provide a clear answer, there are uncertainties about the consequences of the radiation. This has raised the issue of applying the precautionary principle and switch off the wireless networks and use a safer alternative, for example a cable system. However, the decision-makers argue that the uncertainties and the risk need to be balanced with the benefits of the activity. Some type of cost-benefit analysis is required. But it is not obvious how such an analysis should he performed in a case like this, and the purpose of this paper is to present and discuss two possible approaches, one based on willingness to pay and one based on expected net present value calculations. 

In the paper we compare this approach with a standard cost-benefit analysis (CBA) based on expected net present value (E[NPV]) calculations, reflecting the decision-maker s WTP. Using the CBA the expected benefits need to be determined and the decision-maker must specify the value of improved health effects. According to this approach the activity is beneficial when its expected net present value is positive (Fuguitt etal. 1999).
