Present Value of Perpetuity
The current worth of a stream of equal payments that continues indefinitely.
What is PV of Perpetuity?
A perpetuity pays a fixed cash flow forever, with no end date. The present value of a perpetuity simplifies to the payment divided by the discount rate — a surprisingly tidy result that falls out of the infinite geometric series when r > 0. Perpetuities are rare in practice (the British government's consols are a classic example), but the formula is widely used as an approximation for very long-duration assets such as preferred stocks, real estate in perpetuity, and the terminal value in discounted cash flow models.
