Nominal and Real Value of Money
The previous article was an introduction about the two basic
decisions that corporate finance helps a corporation in making. Prima-facie,
these two decisions may look pretty simple. After all everyone raises money in
their daily lives and puts it to productive use. Simple accounting can tell us
whether or not we should make those financing and investing decisions. So, why
is there a need for a complicated subject called corporate finance to make
these decisions? Well, it turns out there is a need? The need arises because of
this concept of nominal and real value of money. This article will explain why
corporate finance is required:
The Concept of Inflation
We are all intuitively aware of the concept of inflation. We
know that money loses its value every year. The same amount of money will
purchase less and less every year. Let’s say that $100 is required to purchase
a certain commodity of goods today. So if there is an inflation of 10%, the
same goods will be available for a $110 next year.
Introduction to Nominal Value of Money
So, if we made an investment that was yielding 9% return
this year, we would have a total of $109 next year from the $100 we had
invested. In accounting terms we would have a profit of $9. This is because we
are only considering the nominal values. Nominal values do not consider the
effect of inflation, opportunity cost of capital and such other forces which
cause the value of money to decrease in a given time period.
Nominal values present a distorted image of the firm’s
performance to its shareholders and this is to say the least. Consider the case
we discussed above. Here, the firm has lost 1% purchasing power. This means
they were better off consuming the $100 in year 1 and could have purchased more
goods with it rather than investing it and consuming $109 a year later. Thus,
if nominal values are considered, firms will end up eroding their capital by
investing their money in projects that offer a rate of return that is below the
firm’s cost of capital.
Introduction to Real Value of Money
To offset this problem, specialists in corporate finance
have come up with the concept of real value of money. The real value of money
takes into account inflation, opportunity cost of capital and such other
forces. Thus, firms that base their calculations on these inflation adjusted
values make better financial decisions as compared to those that do not. The
calculation for both real as well as nominal values is simple and can be done
with the help of the following formula:
Real Value = Nominal Value / (1 + (i / 100))
i = The prevailing inflation rate in the market
Subjectivity in Real Value of Money:
It must be understood that the real and nominal values of
money are subjective. This is because, they are determined using the inflation
rate. There is no single measure of inflation. The government itself produces
multiple estimates of inflation. Also, for the purpose of the company’s
calculation, these measures may not be good enough. So the company may create
its own inflation index depending on which the real values are calculated.
Thus, there is widespread subjectivity in this calculation. Different companies
use different rates to convert nominal values to real values.
