You just type in the payment amount and the interest rate, and with a quick click, you’ll know the total value of those never-ending payments.
It’s like a magic trick that tells you the value of money that keeps coming in forever!

When it comes to financial planning and investment, understanding the concept of perpetuity and its calculations can play a crucial role in making informed decisions.
A perpetuity is a type of investment that offers regular, equal payments indefinitely.

## What is a Perpetuity?

Perpetuity is like getting a set amount of money regularly, over and over again, forever. Imagine receiving a fixed payment every month or every year, and it never stops. That’s what we call a perpetuity.

Now, there’s a small catch. Even though you keep getting the same amount of money each time, the value of that money isn’t the same. It’s like saying a dollar you have today is worth more than the same dollar you’ll get in the future. So, while the payments go on forever, each one is a bit less valuable than the previous one because of how money works over time. Let’s check it in detail.

• Regular: You get these payments at the same time intervals, like a pattern.
• Fixed: The amount of money you get each time is always the same, and doesn’t change.
• Indefinitely: These payments just keep going on and on, without ever stopping.

## Present Value of a Perpetuity Calculator

### Steps on how to check Perpetuity with the Perpetuity calculator

Open the Calculator Page above.

#### Enter Payment Amount

Locate the “Payment Amount” input field in the form.

Type in the amount you expect to receive regularly.

#### Enter Interest Rate

Find the “Interest Rate (%)” input field.

Enter the interest rate as a percentage. For example, if the interest rate is 5%, enter “5.”

#### Click “Calculate Perpetuity Value”

Locate the “Calculate Perpetuity Value” button.

Click the button after entering the payment amount and interest rate.

#### View Result

Look for the result displayed below the form.

The calculated perpetuity value will be presented, and rounded to two decimal places.

### Understanding the Perpetuity Formula

The perpetuity formula is used to calculate the present value of a series of equal cash flows that are expected to continue indefinitely. It takes into account the interest rate and the payment amount to determine the present value. The formula is given as:

PV= CF/r

Where:

PV is the present value of the perpetuity,

CF is the cash flow received each period, and

r is the discount rate (interest rate) per period.

### Example of Perpetuity

Let’s say you have an investment that generates a constant cash flow of \$1,000 per year indefinitely, and you want to find the present value of this perpetuity. If the discount rate (r) is 5%, you can use the formula as,

PV= CF/r

PV= 1000/0.05

PV= 20,000.

## How to Multiply Your Present Value for Money with Perpetuity Calculator?

Considering the above example with a cash flow of \$1,000 per, discount rate (r) as 5%, and applying formula, we get

PV= CF/r

PV= 1000/0.05

PV= 20,000.

Now, to calculate the total value when multiplied by a certain number of periods, you can use the following formula:

Total Value=PV×n

Where:

• TotalValue is the result of multiplying the present value by the number of periods,
• PV is the present value from the perpetuity formula,
• n is the number of periods.
1. Use Perpetuity Calculator
• Input the payment amount (C) and the interest rate (r) into the perpetuity calculator.
• Obtain the present value (PV).
2. Multiply by Number of Periods
• Decide on the number of periods (n) you want to calculate for.
3. Apply Formula
• Use the formula
• TotalValue=PV×n to find the result.

Let’s illustrate with an example

• C (Payment Amount): \$100
• r (Interest Rate): 0.05 (5%)
• n (Number of Periods): 10

PV=100/0.05
=2000

Total Value=2000×10 =20,000.

In this example, if you have a perpetuity with a payment amount of \$100 and an interest rate of 5%, the total value after 10 periods would be \$20,000.

## Factors Affecting Perpetuity Payments

### Impact of Growth Rate on Payments

The growth rate of perpetuity payments significantly influences the payment amounts over time.
A growing perpetuity, in contrast to a regular perpetuity, offers increasing payments at a predetermined rate.

### Understanding the Relationship Between Present Value and Annuity Payments

Perpetuity payments can be compared to annuity payments, which are finite and last for a specific period.
The perpetuity’s present value represents the total amount that an investor will receive if the perpetuity continues indefinitely, while annuity payments cease after a set duration.

### Calculating the Infinite Cash Flows

As perpetuity payments extend indefinitely, the calculation of infinite cash flows becomes a crucial factor in determining the overall value and attractiveness of the investment.

## When to Use a Perpetuity Calculator?

Perpetuity calculations can be applied in various real-life financial scenarios, that offer perpetual income streams.
Utilizing a perpetuity calculator helps in assessing the present value and potential returns of such investments.

## What is Growing perpetuity? Present value of growing perpetuity

A growing perpetuity is also known as a perpetuity with growth. It involves a series of cash flows that increase at a constant rate indefinitely. To calculate the PV of growing perpetuity, we need to apply the growing perpetuity formula.

PV = C / (R – G)

Where,

PV is the present value,

C is the initial cash flow,

R is the discount rate,

G is the growth rate.

### Growing perpetuity example

Initial Cash Flow (C): \$100
Discount Rate (r): 5%
Growth Rate (g): 3%

PV=\$100/(0.05-0.03)

PV= 100/0.02

PV= 5000

In this example, the present value of the growing perpetuity is \$5000. It means that receiving an initial cash flow of \$100, with a growth rate of 3% and a discount rate of 5%, is equivalent to having \$5000 today. The cash flows are expected to increase by 3% each period indefinitely.

### FAQs

#### What is a Perpetuity Calculator?

A Perpetuity Calculator is a tool used to compute the present value of a series of equal cash flows that continue indefinitely. It’s particularly useful in finance to evaluate the current worth of a perpetual stream of payments.

#### What is a perpetuity in financial terms?

Perpetuity refers to a financial arrangement where a fixed sum of money is received or paid at regular intervals indefinitely.

#### Can the Perpetuity Calculator handle varying cash flows?

No, the calculator is specifically designed for perpetual cash flows that remain constant over time. For varying cash flows, other financial tools may be more appropriate.

#### Why is the Perpetuity Calculator useful?

It helps individuals and businesses assess the current value of a perpetual stream of cash flows, aiding in investment decisions and financial planning.

#### What discount rate should I use?

The appropriate discount rate depends on various factors, including the risk associated with the cash flows. It’s often based on prevailing interest rates or the investor’s required rate of return.

#### Can I use the Perpetuity Calculator for monthly cash flows?

The calculator is designed for annual cash flows. For monthly cash flows, convert the annual rate and cash flow accordingly (e.g., divide the annual rate by 12 for monthly and multiply the cash flow by 12 for yearly).

#### Does the calculator account for inflation?

No, the calculator assumes a constant cash flow over time and doesn’t consider inflation. Adjustments for inflation may be needed for more accurate financial analysis.

#### Is the Perpetuity Calculator applicable for business valuation?

Yes, it can be used in business valuation to estimate the present value of perpetual cash flows, helping in determining the intrinsic value of a business.
