Time value of money explained with relevant examples

Time value of money is a concept that refers to the greater benefit of receiving a given amount of money at present rather than in the future, due to its earning potential. Money could be invested in a bank account and earn interest even for an overnight period. Interest earned will depend on the rate of return offered by government bonds (risk-free assets), inflation, liquidity risk, default risk, time to maturity, and other factors.

Uses

In a nutshell, time value calculations allow people to establish the future value of a given amount of money, at present. The present value (PV) is the money you have today. The future value (FV) is the accumulated amount of money you get after investing the original sum at a certain interest rate and for a given time period, say, 2 years. The concept has a wide range of applications in corporate financial matters-bonds, shares, loan facilities among others.

Fundamental formulas in time value of money calculations

Let,

FV= future value

PV= present value

r= interest rate

n=number of investment periods per year

t= number of years

Note: Besides annual interest payments, interest could be compounded monthly, quarterly or semi-annually. If for instance, interest is payable quarterly, then we have 12/3 i.e 4 investment periods per year.

FV= PV(1+ r/n)n*t

PV= FV(1+ r/n)-n*t

Question

Suppose an individual invests $10,000 in a bank account that pays interest at a rate of 10% compounded annually. What will be the future value after 2 years?

A. $12,000

B. $12,100

C. $22,000

Solution

The correct answer is B.

PV=10,000, r=0.1, n=1, t=2

FV=10,000(1+0.1/1)1*2

=10,000(1.1)2

=12,100

To confirm our answer, we could work out the PV of a future value of 12,100 invested under similar terms, starting with the FV of $12100.

PV=12,100(1+0.1/1)-(1*2)

=12,100(1.1)-2

=$10,000

Points to note

First, establish all the components of the relevant formula before commencing actual calculation. Secondly, only the term within the brackets is subject to the power function.

The concept of time value of money serves as the foundation for more concrete financial calculations such as simple interest, compound interest, and the value of stocks/bonds at any given point in time.
