There are few actual perpetuities in existence (the [[United Kingdom]] (UK) government has issued them in the past; these are known and still trade as [[consols]]). A number of types of investments are effectively perpetuities, such as real estate and [[preferred stock]], and techniques for valuing a perpetuity can be applied to establish price. Perpetuities are but one of the [[time value of money]] methods for valuing financial assets. Perpetuities are a form of ordinary annuities.
The concept is closely linked to [[Terminal value (finance)|terminal value]] and terminal growth rate in [[Valuation (finance)|valuation]].
