Net Present Value

Net present value can be defined over a certain period of time as the difference between the present value of cash inflows and the present value of cash outflows. Net present value is utilised in investment planning and capital budgeting for analysing the profitability of a project or a projected investment.

Net present value, in other words, is obtained from the calculations that figure out the current value of a future stream of payments. This calculation is done utilising the right discount rates. Generally, having a positive net present value makes a project worth undertaking, whereas ones with a negative NPV are not.

What is net present value (NPV)?

The method of net present value is primarily utilised for financial analysis to determine the feasibility of investing in a business or a project. The comparison happens between the present value of future cash flows with the current initial investments. Do you want to understand in detail “what is net present value”?

As and when an organisation decides to expand, there are certain important decisions involving huge capital investments that it has to take. An organisation at the point of expansion has to take calls on investment very carefully and smartly. In such phases of businesses, a company often takes the help of capital budgeting tools, which is among the popular net present value methods, and decides on the most profitable investment.

Alternatively, have you beenthinking of investing in mutual funds?

Key takeaways

Let us take a look at the key takeaways of NPV, listed down below:

• The net present value is utilised for the calculation of the current value of a future stream of payments to be obtained out of a project, company, or investment.

• You have to estimate the timing and amount of the future cash flows to be able to calculate the net present value. Additionally, you are required to pick a discount rate that is equal to the minimum acceptable return rate.

• Note that the discount rate could be reflecting your cost capital as well as the available returns on any alternative investments of comparable risk.

• The rate of return is estimated to be over the discount rate in case the NPV of an investment or a project turns out to be positive as per the calculations.

Net present value (NPV) formula

It is quite simple and easy to learn and figure out how to calculate the NPV. However, it is important for you to remember that the net present value formula could vary based on the consistency and the number of cash flows you are dealing with.

In an instance where there is only one cash flow associated with a project, the net present value formula below is what you may use to calculate the NPV:

NPV = Cash flow / (1+i)^t - Initial investment

Here, “i” is the required return of the rate of discount, and “t” equals the number of time periods.

On the other hand, in case you are looking at a longer project which involves multiple cash flows, the net present value formula in such an instance is a little different.

NPV = Today’s expected cash flows value - Today’s invested cash value

If the results show that you have a positive NPV, that indicates that the projected earnings are over your anticipated costs; which means that the investment is likely to be beneficial. However, if the NPV is negative, the investment is likely to end up in a loss. So, if you are trying to figure out and take a call before making an investment, it might be a good idea to calculate the NPV and go ahead for projects where the results indicate a positive NPV.

How to calculate net present value (NPV)?

As explained earlier, you would need to discount the cash flows value at a particular rate to be able to derive the present value of the same. You can derive at this discount rate keeping in mind the returns of investment with similar cost of borrowing or risks. Net present value takes into account the time value of money. The time value, to put simply, means that a rupee has more value today than it will tomorrow. The NPV aids in deciding whether or not it would be wise to take up a new project based on the present cash flows value.

Role of NPV

Here are the roles that the net present value has:

• The net present value method plays the role of determining the worth of a business, project, an investment, or a series of cash flows.

• The NPV method is particularly known for being all-encompassing as it takes into account all expenses, capital costs, revenues, as well as risks associated with an investment.

• It additionally also takes into consideration the timing of every cash flow.

What NPV can tell you?

The net present value accounts for the money’s time value, and can be utilised for the comparison of the rates of return of multiple projects, or to compare a projected return rate with the hurdle rate required to get approval on an investment. The time value of money is shown in the formula of NPV by the rate of discount, which could be a hurdle rate for a project that is based on a company’s cost of capital; an example being the WACC or the weighted average cost of capital. It does not matter which procedure is used to determine the rate of discount; if a NPV is negative, it is for sure that the expected rate of return is likely to fall short of it, which means that the project is not going to create value.

The net present value is also known as the discounted cash flow (or DCF) analysis, when it comes to the evaluation of corporate securities. Warren Buffett came up with the method to run through a comparison of a company’s future discounted cash flow and its current value.

The discount rate is an important part of the NPV formula. It tells us that as far as the rate of interest remains positive, a rupee today is of more value than it will be tomorrow. Inflation reduces the money’s value as time passes by.

Why is net present value (NPV) analysis used?

The net present value analysis is utilised to figure out how much value a project, an investment or any series of cash flows has. This method is an all-encompassing metric, as it takes into consideration all expenses, revenues, and capital costs related to an investment in its free cash flow (pr FCF).

It not only factors in all costs and revenues, but also takes into consideration the timing of every cash flow, which could result in a huge impact on an investment’s present value. It is, for example, much better to be seeing cash inflows sooner and cash outflows later, than seeing the opposite.

Advantages of net present value method

Let us now look at the key advantages of the NPV method. As it considers the time value of money (or TVM), it thus translates the future cash flows into today’s rupees. As inflation has the power to erode buying power in the future, the net present value gives you a very useful measure of the potential profitability of your project. Additionally, the NPV also provides you with a clear number that managers can compare with the initial investment to figure out the success of an investment or a project.

Time value of money

The NPV method is a tool that is used to analyse the profitability of a certain project. It takes into account the time value of money. The cash flows in the years to come are likely to be of lesser value than of the cash flows today. Therefore, the further the cash flows, the lesser the value will be. This is an important aspect, and is correctly considered as part of the NPV method. This will allow your organisation to go through with the comparison of two similar projects smartly. For instance, if Project A has a life of 3 years, and a cash flow that is higher during the initial period; and if Project B has a life of 3 years but a higher cash flow in its latter years, then as per the NPV method, you should be able to wisely choose Project A because the cash inflow today hold more value compared to any inflows tomorrow.

Comprehensive tool

The net present value method is a comprehensive tool because it takes into account all the inflows, outflows, risks associated, and the time period as well. Taking into consideration all different aspects of an investment is what makes this tool comprehensive.

Value of investment

The NPV method not only helps you determine whether or not a project will be profitable, but it also provides you with the total profits value. The NPV tool helps quantify the gains and/or losses from an investment.

Limitations of the net present value method

It is equally important for you to be aware of the limitations of the net present value method. This is to be able to make smart decisions, and having the clarity to make wise choices while making an investment.

Discounting rate

One of the biggest limitations of the net present value method is that the rate of returns has to be determined. This assumption can result in varied results. For instance, if the rate of return is assumed to be higher, it will show you a false negative net present value. On the other hand, if it is assumed to be lower, it will show a false profitability of the said project, and hence result in you making a wrong decision if you are basing it entirely on the NPV results.

Different projects are not comparable

The net present value cannot be utilised for running a comparison between two projects which do not belong to the same time period. The NPV method cannot be utilised to compare two projects with different time periods or risks associated, because sometimes businesses have a fixed budget and sometimes they do have two project options as well.

Multiple assumptions

The net present value also has to make assumptions in case of inflows and outflows. There could be a large expenditure coming to surface only later on in the project, which you may not have been initially able to determine. Inflows are not always as per early expectations.

ROI vs NPV

The return on investment, also known as the ROI, and the present value or the NPV are two methods of evaluation of the potential profitability of an investment. But, what is the difference between the two? The ROI represents the net value that you will be receiving from an investment over a certain period of time. Here is the formula for determining the ROI:

ROI = (Total benefits - Total costs) / Total costs

The ROI formula is quite simple and easy, but perhaps because it is so simple, it is quite possible that it does not provide you with the larger picture. It is important to note that the ROI does not factor in the time value of money, which is exactly what makes this method a little less effective measurement form, as compared to the NPV method.

The NPV in contrast is a much more complex equation. It pays more attention to when the benefits and costs occur, before it converts them into today’s value. The NPV method, considering the time value of money, gives you a much deeper insight into the viability of all your investment options. While the ROI shows you the relative performance of investments, the NPV rather focuses on the absolute value that is created.

Conclusion

The net present value, as you now must understand, is the most widely utilised and the most detailed method which evaluates the profitability of an investment. The NPV is a tool that helps you make decisions for a project, a business, or an investment you are in two minds about making, by giving you a clearer picture of what lies ahead in time.
