Future value calculations can be categorized into two types:
Future Value of a Lump Sum:
Future Value of an Annuity:
Utilizing one of the numerous free online calculators or financial calculator applications, such as the HP 12C Financial Calculator, accessible on platforms like Google Play and the Apple App Store, is the simplest method to compute future value. Most spreadsheet programs also offer functions for future value calculations. However, for this course's purposes, we will reference present value, future value, and annuity tables provided within the course materials. The future value (FV) formula assumes a consistent rate of growth and a single initial payment that remains untouched throughout the investment period. The FV calculation can be approached in one of two ways, depending on the type of interest earned:
i) Using Simple Annual Interest:
If an investment earns simple interest, the FV formula is:
If an investment earns simple interest, then the FV formula is:
FV = P × (1 + R × T)
Where,
FV= Future Value
P = Principal amount or Investment Amount
R = Interest rate
T = Number of years
FV= Future value or final amount
For example, assume a Rs.1,000 investment is held for five years in a savings account with 10% simple interest paid annually.
In this case, the FV of the Rs.1,000 initial investment is Rs1,000 × [1 +
(0.10 x 5)], or Rs.1,500.
(ii) Compounded Annual Interest
In contrast to simple interest, which applies the interest rate solely to the initial investment, compounded interest applies the rate to the cumulative balance of each period. In the given example, during the first year of investment, an interest of 10% × Rs.1,000, or Rs.100, is earned. However, in the subsequent year, the account balance stands at Rs.1,100 instead of Rs.1,000. Consequently, to compute compounded interest, the 10% interest rate is applied to the entire balance, resulting in second-year interest earnings of 10% × Rs.1,100, or Rs.110.
The formula for determining the Future Value (FV) of an investment earning compounded interest is:
FV = P × (1 + R)t
Where,
P = Principal amount or Investment amount
R = Interest rate
t = Number of years
Using the above example, the same Rs.1,000 invested for five years in a savings account with a 10% compounding interest rate would have an FV of Rs.1,000 × [(1 + 0.10)5], or Rs.1,610.51.
Future Value of an Annuity Example
A common use of future value is planning for a financial goal, such as funding a retirement savings plan. Future value is used to calculate what you need to save and invest each year at a given rate of interest to achieve that goal.
In general terms the future value of an Annuity is given has the following formula:
FV An = A[(1 + r)n − 1]/r
Where,
Fv An= Future Value of annuity
A = constant Periodic flows
r= Interest rate period
n= duration of annuity
Example 1
If you contribute Rs. 2,400 every year to a retirement account and want to calculate what that account will be worth in 30 years; you could use the future value of an annuity formula. For this example, you assume a 7% annual rate of return:
Over 30 years, you would contribute a total of Rs. 72,000, but because of the time value of money and the power of compounding interest, your account would be worth Rs. 226,706 (with an annual 7% rate of return), or more than three times the amount you invested.
Future value is also useful to decide the mix of stocks, bonds, and other investments in your portfolio. The higher the rate of interest, or return, the less money you need to invest to reach a financial goal. Higher returns, however, usually mean a higher risk of losing money.
The term [(1 + r)n — 1]/r is referred to as the future value interest factor for an annuity(FVIFAr.n) and the value of this factor for several combinations of r and n can be found in the annuity table.
Some common uses for present value include:
Understanding the concept of the time value of money is crucial for financial planning, influencing decisions ranging from asset acquisition to investment strategies. The future value reflects how time affects the worth of money, and leveraging future value alongside other metrics can facilitate informed financial choices.
From a financial management perspective, the significance of the time value of money becomes evident in several ways:
The Time Value of Money can be calculated in two ways. The following formula can be used to calculate the present value (PV) of future cash flows:
PV = FV X (1 + r)-n or FV= PV x (1+r)n
Where:
PV — Present Value.
FV — Future Value.
r — interest rate.
n — number of periods.
Notice the negative sign of the power n which allows us to remove the fractions from the equation.The following formula allows us to calculate the future value FV) of cash flow from its present value.
FV = PV X (1 + r)n
Where:
FV — Future Value.
PV — Present Value.
r — interest rate.
n — number of periods.
Effect of Compounding Periods on Future Value
The number of compounding periods used in time value of money estimates can have a significant impact. If the number of compounding periods is raised to quarterly, monthly, or daily in the Rs. 10,000 example above, the concluding future value calculations are:
This demonstrates that the time value of money is determined not just by the interest rate and time horizon, but also by the number of times the compounding computations are performed each year.
In cases where we have more than one compounding period of interest per year, we can tweak the formula, to make sure we are using the appropriate portion of annual interest:
Where:
FV — Future Value.
PV — Present Value.
r — interest rate (annual).
n — number of periods (years).
t — number of compounding periods of interest per year. If it is quarterly t=4, for half-yearly t=2, and for monthly t=12.
The time value of money is a fundamental concept in determining Net Present Value (NPV), Compound Annual Growth Rate (CAGR), Internal Rate of Return (IRR), and other financial calculations.
In practice, there are two types of time value of money concepts described below:
(i) Time Value of Money for a One-Time Payment
(ii) Time Value of Money - Doubling the Period
Example 1: Assuming a sum of Rs. 10,000 is invested for one year at a 10% interest. The future value of that money is:
FV = Rs. 10,0000 X [1 + (10%/1)]1x1 = Rs. 11,000
The formula can also be adjusted to obtain the present value of the future total. For instance, the value of Rs. 5,000 to be received after a year, compounded at a 7% interest, is:
Example 2: To illustrate the concept of the time value of money, let's consider the following scenario. We are considering an investment in a machine that will yield annual cash flows of Rs. 38,500 for the next ten years. The initial cost to acquire the machine is Rs. 2,50,000, and at the end of its useful life, we expect to sell it for Rs. 1,40,000.
We can create a simple schedule to outline our cash flows per period. For simplicity, let's assume zero inflation over the period. We'll start with the initial investment and list the annual cash benefits.
At the conclusion of our table, the cash inflow at the end of the 10th year amounts to Rs. 1,78,500, which incorporates Rs. 1,40,000 from the resale of assets. When viewed in absolute terms, it appears that we will recoup twice the amount we invested over the years. However, to gain a clearer understanding, we need to consider the Time Value of Money. Utilizing the company's Weighted Average Cost of Capital (WACC) as the discount rate is optimal as it accurately reflects the enterprise's true cost of capital. We can proceed to calculate the Net Present Value (NPV) of the cash flows using Excel's more sophisticated NPV computation.
The cash flows of Rs.38,500 here can be considered as an annuity of 10 years of Rs.38,500 and the resale value of Rs. 1,40,000 is to be discounted to the present value. Here we have to find the present value of an annuity of Rs.38,500 of 10 years tenure value occurring after 10 years. Here the discount factor is going to be the weighted average cost of capital (WACC) which is 10%.
Now putting the values in the formula
Where is the present value interest factor from annuity (PVIFArn). This value can be found from the present value interest factor for annuity for 10% discount rate and 10 years, and is 6.145. Therefore, present value of annuity of Rs.38,500 would be 6.145 x 38,500 = 2,36,582.50.
Now let us find the present value of Rs. 1,40,000 going to be received ten years hence from now.
The present value in first factor for discount rate of 10% for 10 years is 0.386, therefore present value of Rs.1,400,000 is going to be:
1,40,000 x .386 = 54,040
The present value of cash flows would be Rs. 2,36,582.50 + Rs. 54,040= Rs. 2,90,622.50
The net present value would be:
2,90,622.5 - 2,50,000 = 40,622.5
Since NPV is positive investment can be accepted.
The discounted cash flow analysis (DCF), a widely used method for evaluating investment proposals, relies on the concept of the time value of money. This principle is not only integral to financial planning and risk management but also permeates various sectors of finance. Money's worth is contingent on time, constituting a foundational tenet in finance. Money received today holds a different value than money received in the future, owing to the ability to invest and generate returns. For instance, if given the choice between Rs. 100 now and Rs. 100 in a year, Rs. 100 presently holds greater value as it can be invested at a 10% interest rate, yielding a return of Rs. 10. After a year, Rs. 100 would appreciate to Rs. 110.
Investment Decision: Investment decisions entail current cash outlays for anticipated future cash inflows.
For instance, let's consider a project with a cost of Rs. 100,000, expected to yield cash inflows over 3 years. The company's cost of capital or required rate of return stands at 15%. The question arises: Is the project viable under these circumstances?
Solution: PV of Cash inflows = PV of Rs 40,000 + PV of Rs 50,000 + PV of Rs 30,000 = [40,000 x 0.870] + [50,000 x 0.756] + [30,000 x 0.658]
= Rs 34,800 + Rs 37,800 + Rs. 19,740 = Rs. 92,340
The present value of cash inflows in this example is Rs 92,340, whereas the project cost is Rs 1 lakh. The project is not acceptable since the benefits are smaller than the costs.
Financing Decision: When a business issues a debenture, it receives immediate cash flow. At the end of each year, interest payments (cash outflows) are due. The debenture amount is redeemed after the period.
As a result, cash inflows come first, followed by cash outflows in the financing choice.
These cash flows cannot be compared because they occur at separate times. Finding the discounted value (present value) of interest payments and the redemption value is used to calculate the time value of the payment. The present value of cash outflows is compared to the debenture selling value, and a decision is made on whether to issue debentures.
Understanding the concept of the Time Value of Money is crucial for evaluating the true worth of shares and investment prospects in both companies and projects. This principle underlies nearly every financial decision ever made, whether consciously acknowledged or not. It underscores the importance of starting investments early, emphasizing the advantage of receiving money sooner rather than later, known as temporal preference. In essence, the significance of money's time value has been effectively conveyed.
