How to calculate future value of perpetuity?

Calculating the future value of a perpetuity can be a useful exercise in finance and investment planning. A perpetuity is a stream of equal cash flows that continue indefinitely. Understanding how to calculate its future value can help investors make more informed decisions. So, how exactly can we calculate the future value of perpetuity?

How to Calculate Future Value of Perpetuity?

The formula to calculate the future value of a perpetuity is simple and straightforward. It can be expressed as:

Future Value = Cash flow / Interest Rate

Where:
Future Value = the future value of the perpetuity
Cash flow = the cash flow received annually
Interest Rate = the interest rate for the perpetuity

Here is an example to illustrate this better. Let’s say you receive $100 annually from a perpetuity that has an interest rate of 5%. The future value of this perpetuity would be:

Future Value = $100 / 0.05
Future Value = $2,000

Therefore, the future value of the perpetuity in this case would be $2,000.
