If you want to solve your doubts about the basic concepts of economics and finance, this is your site Example of NPV and IRR calculation (with spreadsheet)Statement: We receive the following investment proposal:
– Subtract the amount of the investment (initial outlay)NPV = Sum of discounted cash flows – Initial outlay= 656.52 NPV = 20,656.52 – 20,000NPV = 656.52 €Nowadays these calculations have been transferred to financial calculators or spreadsheets that include functions that calculate NPV by simply entering the value of the initial outlay, cash flows and discount rate.In Spreadsheet:For this example we would proceed as follows:
= NPV (B1;B3:B5) + (- B2) and we will check that it will return the value 656.52b) T I R “The discount rate that makes the NPV equal to zero “It is then a matter of clearing the “k” from the following formula: This calculation, which becomes quite complex when it exceeds the 2nd degree equations, is solved in a simple way with financial calculators or spreadsheets.In Spreadsheet:If we have noted in the cells:

In order to be able to make investment decisions, it is necessary to correctly evaluate the different alternatives that are presented to us. And for this we must have the appropriate mathematical technique that allows us to make that valuation. In this article we will explain how to use NPV and IRR to value an investment.
The NPV is the method consisting of discounting at the present time all the cash flows that the investment will bring us, with a discount or discount rate that takes into account the average cost of the capital used to finance the project (WACC or Weight Average Cost of Capital).
Let’s see how it works with a simple example. Let’s imagine that we have the opportunity to buy an apartment on the beach, which is going to cost us 100,000 €. The expenses for deeds, taxes, registration and other costs in the acquisition amount to € 10,000.
Thus, the total cost of the house is 110,000 €. And the average cost of capital will be 2.09%. – Given that 50.000€ of equity have an opportunity cost of 1% and the remaining 60.000€ that we have financed have a financial cost of 3%.

We can define NPV as the present value of cash flows, net of investments. It provides a measure of the profitability of the project analyzed in absolute value, i.e. it expresses the difference between the present value of the monetary units collected and paid. In turn, it will indicate the increase in the value of the company due to the project.
In this equation we can see how, while at the time of calculating the NPV the interest rate was known, in this case the unknown is the interest rate itself. Once the IRR has been calculated, we compare it with the interest rate used in the NPV calculation:
If the NPV of a project is positive, the IRR will be higher than the interest rate, and vice versa. The explanation lies in the fact that we have defined the IRR as the maximum cost of capital that a project can bear. If the interest rate used to discount the cash flows when calculating the NPV is lower than the IRR, it would therefore be lower than the maximum cost of capital supported and, therefore, the project will be profitable and the NPV will be positive and the IRR higher than the interest rate.

I saw now why I am more given to use the functions of financial mathematics, than the functions of excel. Well, simply for that reason, because excel functions sometimes do not work as we think they should (and all because we do not read the excel documentation, through its help). Now let’s imagine that with the same example, the market interest rate (or the interest rate of an investment), is 4%, and we want to know how much we should invest to obtain those 1.000 euros in 1 year, the 3.000 euros in 2 years, and the 5.000 euros in 3 years. Well, that is as simple as doing this (look at the formula bar in the following image):
As you can see, since the interest rate is lower (4% instead of 4.9602%), we will need to invest a larger amount to obtain the same income of 1,000, 3,000, and 5,000 euros. This means that the 9,000 euros (1,000 + 3,000 + 5,000), which we will receive in the FUTURE, are 8,180.19 euros as of TODAY (taking into account that the interest rate is 4%). That is to say, we will be obtaining the Present Value of the investment. We can check the latter in the following way (look at the formula bar in the following image, where we will see that in E9, the third term of the first equation that I have put in this article appears):
