The function perpetuity computes the present value of an instrument that pays the amount cash at the beginning of each period, forever, starting in one period.

An example of a perpetuity is a stock that pays the same dividends year after year.

Since perpetuity used to be part of the (now deprecated ) finance package, for compatibility with older worksheets, this command can also be called using finance[perpetuity]. However, it is recommended that you use the superseding package name, Finance, instead: Finance[perpetuity].

$\mathrm{with}\left(\mathrm{Finance}\right)\:$
