Compounding Factor


Below is an illustration of what the Net Present Value of a series of cash flows looks like. As you can see, the Future Value of cash flows are listed across the top of the diagram and the Present Value of cash flows are shown in blue bars along the bottom of the diagram. The formula can also be used to calculate the present value of money to be received in the future. You simply divide the future value rather than multiplying the present value.

Number Of Compounding Periods

Second, multiply the number of annual payments by the number of payments each year to find the total number of payments and use this value for N. The expressions for the present value of such payments are summations of geometric series. Therefore, to evaluate the real value of an amount of money today after a given period of time, economic agents compound the amount of money at a given rate.


When a business wants to make an investment, one of the main factors in determining whether the investment should be made is to consider its return on investment. Commonly, not only will cash flows be uneven, but some of the cash flows will be received and some will be paid out.

The discount rate can be thought of as representing the percentage of return that you could have received by investing that dollar, if you had received it today.

The present value factor is the exponent of the future value factor. The future value factor is the exponent of the present value factor. They decide that they will need an income as of age 65 of $80,000 a year, and they project living to age 85. Joseph and Josephine need to know how much money they need at age 65 to produce $80,000 of income for 20 years, assuming they will earn 4% .

Calculations With The Discount Factor Formula

Present value means today’s value of the cash flow to be received at a future point of time and present value factor formula is a tool/formula to calculate a present value of future cash flow. The concept of present value is useful in making a decision by assessing the present value of future cash flow. Annuities are investment contracts issued by financial institutions like insurance companies and banks. When you purchase an annuity, you invest your money in a lump sum or gradually during an “accumulation period.” At a specified time the issuer must start making regular cash payments to you for a specified period of time.

For example, if a cup of coffee presently costs $1.00 and the cost is expected to increase by 10% per year compounded annually, then a cup of coffee will cost $3.138 per cup at the end of 12 years. Rate Of ReturnsThe real rate of return is the actual annual rate of return after taking into consideration the factors that affect the rate like inflation. It is calculated by one plus nominal rate divided by one plus inflation rate minus one.

Present Value Of An Annuity

Present Value of Future Cash Flow is nothing but the intrinsic value of the Cash Flow due to be received in the future. It is a representative amount which states that instead of waiting for the Future Cash Flows if you want the amount today, then how much would you receive.

  • The offers that appear in this table are from partnerships from which Investopedia receives compensation.

The sixth group in Table 1-5 belongs to set of problems that A is unknown and P, i, and n are given parameters. In this category, uniform series of an equal sum, A, is invested at the end of each time period for n periods at the compound interest rate of i. In this case, the cumulated present value of all investments, P, is given and A needs to be calculated.

The revenue or cash flow projected may be low at first but grow over time. Against the annuity payment A, or by using a graphing calculator, and graphing the value of the annuity payment as a function of interest for a given present value. In the latter case, the interest rate is where the line representing the rate of interest intersects the line for the annuity payment.

  • The present value of a single amount allows us to determine what the value of a lump sum to be received in the future is worth to us today.
  • Understanding the concept of present value and how to calculate the present value of a single amount is important in real-life situations.
  • In the latter case, the interest rate is where the line representing the rate of interest intersects the line for the annuity payment.

  • That’s because the impact to your net worth of $7,129.86 today is roughly equal to $10,000 in 5 years net of inflation and interest.
  • The valuation period is the time period during which value is determined for variable investment options.

For a greater degree of precision for values between those stated in such a table, use the formula shown above within an electronic spreadsheet.

In the formula, rate represents the cost of capital or the discount rate, while periods equals the number of years. Calculate the Future Value and Future Value Interest Factor for a present value invested for a future return. Our basic future value calculator sets time periods to years with interest compounded daily, monthly, or yearly. In order to use the equation for future value of an annuity when the payment interval is less than one year, you must make two adjustments. First, divide the discount rate by the number of payments per year to find the rate of interest paid each month.

The Present Value Formula

Always keep in mind that the results are not 100% accurate since it’s based on assumptions about the future.

As per the concept of time value of money, money received today would be of higher value compared to money received in future as money received today can be reinvested to earn interest on it. In short, longer the time in receiving money lower will be its current value. In economics and finance, present value , also known as present discounted value, is the value of an expected income stream determined as of the date of valuation. Time value can be described with the simplified phrase, «A dollar today is worth more than a dollar tomorrow». Here, ‘worth more’ means that its value is greater than tomorrow.

A is the unknown variable, is on the left side, and P, given variable, on the right side. Based on this result, if someone offered you an investment at a cost of $8,000 that would return $15,000 at the end of 5 years, you would do well to take it if the minimum rate of return was 12%. By the end of Year 5, we can see the discount factor drops in value from 0.91 to 0.62 by the end of the forecast period due to the time value of money. The example implies that $1 dollar received one year from the current period would be worth $0.91 in the present day. While the discount rate remains constant throughout the projection, the period number rising is what causes the factor to decrease over time.

Use this PVIF to find the present value of any future value with the same investment length and interest rate. Instead of a future value of $15,000, perhaps you want to find the present value of a future value of $20,000. Present value is the HOW TO COMPUTE FOR PRESENT VALUE FACTOR AND FUTURE VALUE FACTOR concept that states an amount of money today is worth more than that same amount in the future. The only situation in which the present value factor does not apply is when the interest rate at which funds could otherwise be invested is zero.
