Financial Investing 07 – Understand Present Value Versus Future Value

In this article, we will continue the financial investing series with the discussion of financial market structures known present value and future value in macroeconomics.

The concept of present value versus future value is like the concept that a dollar today is worth more than a dollar. In fact, a dollar invested today earning interest will grow in value when the interest is paid and if the dollar plus interest is automatically reinvested for a further period of time, new interest will be earned on both the dollar of original investment and on the interest already earned. As this is repeated over a period of time, we call the result of compounding interest. It is possible to determine the future value of money by using

1. Financial tables.

a) Present value represents the original investment that we have in hand today.

b) Future value represents what that investment will grow to when interest is earned on a sequential renewal of investment, where the original investment plus all interest earned, keeps being reinvested for subsequent periods until maturity.

Here is the formulaFV = PV (1+I)?

whereFV is future value

PV is present value

I  is annual interest rate

n is number of compounding periods

2. Present value of a single sum

In order to determine the present value, we must take the final sum and discount it by the interest factor working backwards from our known single sum.

Here is a formula:PV= FV/ (1+I)?

The definitions for PV, FV, I, n are the same as 1. above.

3. Present value and the amount of the annuity payment of an annuity There are two types of annuities

*Deferred Annuity: receipts on payments are made at the end of the period.

*Annuity Due: the receipts or payments occur at the beginning of the period.

Future value of an annuity helps to calculate how much money needs to be invested today, in order to receive a certain payment in the future.

a) The present value of an annuity is calculated by the formula below

PV = (PMT/i) · [1 – (1 / (1 + i)n)]

wherePV= Present value

PMT= The amount of the annuity payment

i =The annual rate of interest

n =The number of discounting periods

b) The amount of the annuity payment is calculated by this formula below

PMT= (PV·i)/ [1 – (1 / (1 + i)n)]

Where PV= Present value

PMT= The amount of the annuity payment

i =The annual rate of interest

n =The number of discounting periods
