The net present value method can be used to compare competing investment projects in two ways (npv comparison). One is the total cost approach, and the other is the incremental cost approach. Each approach is illustrated below:
The cash flows in net present value analysis are discounted for two main reasons, (1) to adjust for the risk of an investment opportunity, and (2) to account for the time value of money (TVM). The first point (to adjust for risk) is necessary because not all businesses, projects, or investment opportunities have the same level of risk.

Accurate risk adjustment is challenging to perform (hard to get data on correlations, probabilities) Net Present Value (NPV) is the most detailed and widely used method for evaluating the attractiveness of an investment. Hopefully, this guide’s been helpful in increasing your understanding of how it works, why it’s used, and the pros/cons.
Excel offers two functions for calculating net present value: NPV and XNPV. The two functions use the same math formula shown above but save an analyst the time for calculating it in long form.
If the net present value of a project or investment, is negative it means the expected rate of return that will be earned on it is less than the discount rate (required rate of return or hurdle rate#N#Hurdle Rate Definition A hurdle rate, which is also known as minimum acceptable rate of return (MARR), is the minimum required rate of return or target rate that investors are expecting to receive on an investment. The rate is determined by assessing the cost of capital, risks involved, current opportunities in business expansion, rates of return for similar investments, and other factors#N#). This doesn’t necessarily mean the project will “lose money.” It may very well generate accounting profit (net income), but since the rate of return generated is less than the discount rate, it is considered to destroy value. If the NPV is positive, it creates value.
NPV analysis is a form of intrinsic valuation and is used extensively across finance. and accounting for determining the value of a business, investment security, capital project, new venture, cost reduction program, and anything that involves cash flow.
The cash flows in net present value analysis are discounted for two main reasons, (1) to adjust for the risk of an investment opportunity, and (2) to account for the time value of money (TVM). The first point (to adjust for risk) is necessary because not all businesses, projects, or investment opportunities have the same level of risk.
To value a business, an analyst will build a detailed discounted cash flow DCF model#N#DCF Model Training Free Guide A DCF model is a specific type of financial model used to value a business. The model is simply a forecast of a company’s unlevered free cash flow#N#in Excel. This financial model will include all revenues, expenses, capital costs, and details of the business.
Companies often use net present value as a capital budgeting method because it's perhaps the most insightful and useful method to evaluate whether to invest in a new capital project.
To work the NPV formula: 1 Add the cash flow from Year 0, which is the initial investment in the project, to the rest of the project cash flows. 2 The initial investment is a cash outflow, so it is a negative number. In this example, the cash flows for each project for years 1 through 4 are all positive numbers.
Mutually exclusive projects, however, are different. If two projects are mutually exclusive, it means there are two ways of accomplishing the same result.
You wouldn't want to accept two bids for the same project. That is an example of a mutually exclusive project. When you are evaluating two capital investment projects, you have to evaluate whether they are independent or mutually exclusive and make an accept-or-reject decision with that in mind.
The total cost approach is the most flexible method for comparing competing investment projects. To illustrate the mechanics of the approach, consider the following example:
When only two alternatives are being considered, the incremental cost approach offers a simpler and more direct route to decision. Unlike the total cost approach, it focuses only on differential costs.

If $10,000 is the initial outflow investment, and the cash inflows are $1,000 at year one, $6,000 at year two, $3,000 at year three, and $5,000 at year four, then the payback period would be three years, as the first three years are equal to the initial outflow.
For a variety of reasons, financial managers may prefer to represent the defender’s IRR as the defender’s ROA or the defender’s ROE. However, this same manager must be careful to make sure that the cash flows associated with the challengers are consistent with the method used to find the IRR of the defender.
