In finance, the present value (PV) of a perpetuity is calculated using the formula:
\[ PV = \frac{C}{r} \]
where:
- \(C\) is the cash flow received each period,
- \(r\) is the discount rate (expressed as a decimal).
The timing of the cash flows can affect the present value calculation. There are generally two types of perpetuities:
-
Perpetuity at the end of the period: Cash flows begin at the end of the first period. The PV calculation mentioned above applies directly.
-
Perpetuity at the beginning of the period: Cash flows begin immediately. This is often referred to as an annuity due. The PV for this type is calculated using the formula:
\[ PV = \frac{C}{r} \times (1 + r) \]
When you mention "PV timing," it refers to whether the perpetuity is structured with cash flows starting at the beginning or the end of the period.
