In real estate, the income approach to valuation frequently treats the property’s income stream as a perpetuity, making the duration a key input for determining the net present value of the asset. The calculation moves beyond simple present value to incorporate the time value of money with extreme precision.
Understanding Perpetuity Duration Formula and Its Calculation
Unlike standard annuities with defined endpoints, this instrument requires specialized methods to quantify its temporal weight, as the standard present value formula diverges. Comparison with Standard Fixed-Income Instruments.
In this scenario, the duration formula adjusts to (1 + r) / (r - g), provided that the discount rate r is greater than the growth rate g. This inverse relationship occurs because higher discount rates reduce the present value of distant cash flows more significantly, pulling the average payment date closer to the present.
Understanding Perpetuity Duration Formula and Calculation
Economic shocks, regulatory changes, and technological obsolescence ensure that true perpetuities do not exist. Because the cash flows extend to infinity, the standard future value calculation is impossible, but the present value remains finite if the discount rate exceeds the growth rate.
