time value of money


The goal of every organization is to grow and expand within its industry.In order to ensure that business endeavors and projects are going to increase profits and the value of the organization, financial managers look at the time value of money. This concept helps a manager and/or investor comprehend the benefits and the future cash flow to make decisions.
Money has a time value means financial managers must take this time value of money into consideration when making financial decisions. To make decisions they restating money values through time with Time Value of Money Calculations. Time value of money calculations are used to shift rupee values through time. They can be used to state future cash flows in present value terms or to restate present value amounts into future cash values. The calculations are the most powerful tool available for making financial and business decisions. Once the methods of restating money values through time is mastered, they can be used for restating cash flows in such a way as to make them comparable in the financial decision making process. The calculation of present values is the foundation for many financial decisions facing both individuals and managers in all types of firm.
The time value of money is a tool to understand the effective rates on business loans or the true return on an investment by helping the manager determine the actual value of money now and in the future based on interest rates, discount rates, expected costs, and expected sales. Through targeted analysis, organizations are able to use this information to decide whether projects, big or small, simple or complex, are going to be beneficial to the company. By observing various tools and indicators such as future value, present value, future value of an annuity, and present value of an annuity, companies can determine the expected return on an investment to ensure that it will result in increased profits.
There are several reasons that the time value of money is important for businesses. One is obviously their ability to invest the funds and earn interest. Another reason is making contract and other expenditure decisions; such as the use of installment payments. The consideration of issuing long-term and short-term debt is yet another reason the time value of money is an important aspect to consider. The concept, time value of money also important to take capital allocating decisions.
The decision to invest in new plant and equipment or the introduction of a new product in the market requires using capital allocating, capital budgeting techniques, and determining whether future benefits are large enough to justify current spending. To make those decisions, managers should fully understand the various financial applications of the time value of money and the components of discount/interest rate.
The time value of money is the value of money figuring in a given amount of interest earned over a given amount of time.
Time value of money derived from The idea that money available at the present time is worth more than the same amount in the future due to its potential earning capacity, money available sooner give chance to consume or invest and earn more money. Time value of money is also referred as present discounted value.
TVM can calculate in two main ways,
· Simple interest
· Compound interest
Simple interest- when investing if the return is only from the principle amount that invested that method of investment called as simple interest.
Compound interest- when the principle amount and the interest which earn from the principle amount also earn the return investment called as compound interest.
Using simple and compound methods can value present money’s future value and present values the future cash flows.
Present value The current worth of a future sum of money or stream of cash flows given a specified rate of return. Future cash flows are discounted at the discount rate, and the higher the discount rate, the lower the present value of the future cash flows. Determining the appropriate discount rate is the key to properly valuing future cash flows, whether they are earnings or obligations.
Present value of an annuity An annuity is a series of equal payments or receipts that occur at evenly spaced intervals. Leases and rental payments are examples. The payments or receipts occur at the end of each period for an ordinary annuity while they occur at the beginning of each period for an annuity due.
Present value of a perpetuity is an infinite and constant stream of identical cash flows.
Future value is the value of an asset or cash at a specified date in the future that is equivalent in value to a specified sum today.
Future value of an annuity (FVA) is the future value of a stream of payments (annuity), assuming the payments are invested at a given rate of interest.

Calculations
Money received sooner rather than later allows one to use the funds for investment or consumption purposes. Rs 100 bill has the same value as an Rs100 bill one year from now, although the bill is the same, person can do much more with the money if they have it now because over time they can earn more interest on money.
Example- Suppose You has won a cash prize of Rs 10000. You have two options:

1) Receive Rs10,000 now

OR

2) Receive Rs10,000 in after few years
If you are like most people, you would choose to receive the Rs10, 000 now. It is because of the time value of money.
Time value of money can be calculated under the interest rate as well as under the present value and the future value.

Simple interest
Interest earned only on the original investment, no interest is earned on interest.
Interest =Interest rate * Initial investment 

Future value
Amount to which an investment will grow after earning interest.
FV =P (1+ rt)
FV= Future Value
PV = Present value
r =Interest rate
t =Time period
Example-Suppose you have Rs1000 invested in a bank account and bank currently paying an interest rate of 6% per year on deposits under simple interest. What will be future value of your account after three years?
Interest rate * Initial investment =Interest
1st year =0.06 * 1000= 60 or Fv= P (1+rt)
2nd year=0.06 * 1000= 60 = 1000 (1+0.06*3)
3rd year=0.06 * 1000= 60 =Rs 1180
Total interest = 180
Future value = 1000+180
=Rs1180

Present value
The current value of future payment.
Fv = P (1+rt)
P (1+rt) =FV
P =FV
(1+rt)
FV= Future Value
P = Present value
r =Interest rate
t =Time period
Example-Suppose you have receive Rs 1180 after invested on a bank in three years. Interest rate is 6% under simple interest. What is the value of money today?
P =FV
(1+rt)
= 1180
(1+0.06*3)
= Rs 1000

Compound Interest
When interest paid on an investment is added to the principal in each year or interest earned on interest.
Future value
How much a sum will grow in a certain number of years when compounded at a specific rate by using accumulated factor= (1+r).
FVt=P (1+r) t
FV= Future Value
P = Present value
r =Interest rate
t =Time period
There are many other equations for calculate future value under quarters, month, daily and semi-annually.
Semi annually = FV= PV (1+r2/2)2t
Quarter = FV= PV (1+r4/4)4t
Month = FV= PV (1+r12/12)12t
Daily = FV= PV (1+r365/365)365t
Example-Suppose you have Rs1000 invested in a bank account and bank currently paying an interest rate of 10% per year on deposits under compound interest. What will be future value of your account after ten years?
FVt=P (1+r) t
Fvt= 1000 (1+0.1)10
= Rs 2594
 
Present value
The current value of a future cash flow when compounded at a specific rate by using discounting rate= 1
(1+r) t
PV= FV
(1+r)t
FV= Future Value
P = Present value
r =Interest rate
t =Time period
Example-Suppose you have receive Rs 2594 after invested on a bank in ten years. Interest rate is 10% under compound interest. What is the value of money today?
PV= FV
(1+r)t
= 2594
(1+0.1)10
=Rs 1000

Example-Saving to buy a new computer
· Suppose you need Rs 30000 after two years to buy a new computer. The interest rate is 8% per year. How much money should you set aside now in order to pay for the purchase?
PV= Rs 30000 / (1+0.08)2
=Rs 25720
· Suppose you have Rs 25720 in the bank to buy a new computer after two years. The interest rate is 8% per year. What will be the future value of your money after two years?
FV=Rs 25720 (1+0.08)2
=Rs 30000

Multiple Cash Flows
Investments which are involve many cash flows overtime.
Future value of multiple cash flows
Future value of a stream of cash flows.
Example - Suppose you are going to purchase a computer in 3 years. You plan to same amount of money each year. You might be able to put Rs1200in today, and anther Rs1400 in 1year and Rs 1000in next year. If you earn 8% rate of interest how much you able to spend on a computer in 3 years?
Year 0 1 2 3
1200 1400 1000
1000*(1.08)=1080.00
1400* (1.08)2=1632.96
1200*(1.08)3=1511.65
Future value in 3 years =4224.61

Present value of multiple cash flows
Present value of a stream of cash flows.
Example - Suppose you are entering to an installment plan to buy a new car where you pay Rs8000 today and make payments of Rs 4000 each of next 3 years. Interest rate is 8% and you are going to buy it in 3 years. What is the present value of that cash flow?
8000 4000 4000 4000
Year 0 1 2 3
8000
4000 = 3703.70
(1.08)
4000 = 3429.35
(1.08)2
4000 = 3175.32
(1.08)3
Present value =18308.37

Perpetuities
Stream of level cash payments that never end.
Present value of perpetuity= C = cash payment
r interest rate
Example-Suppose a worthy person wishes to finance on your university. If the rate of interest is 10% and the aim is to provide Rs100000 a year forever. What is the amount of that cash flow in today?
PV of perpetuity = 100000
0.10
= Rs 1,000,000

Annuities
Equally spaced level of stream of cash flows.
· Present value of annuities
Present value of t-year annuity= Payment * Annuity factor
Present value of t-year annuity= C * [1/r – 1/r (1+r) t]
Example- Suppose the Kangaroo offers an “easy payment “scheme of Rs4000 a year at the end of each of the next 3 years. The interest rate is 10% and what is the present value of annuities?
4000 4000 4000
Year 0 1 2 3
4000 = 3636.36
(1.10)
4000 = 3305.78
(1.10)2
4000 = 3005.25
(1.10)3
Present value= 9947.39
Or otherwise it is easy to calculate using formula.
Present value = 4000 * [1/0.10 – 1/0.10(1.10)3]
= 4000 * 2.487
= 9948
· Future value of annuities
FV of annuity= PV of annuity *(1+r) t
= [1/r – 1/r (1+r) t] * (1+r) t
= (1+r) t -1
r

Example-Suppose you are setting aside Rs 3000 at the end of every year in order to buy a mountain bike. If your saving earn interest 8% a year ,how much will they be worth at the end of 4 years ?
3000 3000 3000 3000

Year 0 1 2 3 4
3000
3240 = 3000*(1.08)
3499 = 3000*(1.08)2
3779 = 3000*(1.08)3
Future value of annuity = 13518
Or otherwise it is easy to calculate using formula.
Future value of annuity = C *(1+r) t -1
r
= 3000 * 4.506
= 13518
