Calculator of the Present Value of a Growing Perpetuity


Instructions: Compute the present value (\(PV\)) of a growing perpetuity by indicating the yearly payment (\(D\)), the interest rate (\(r\)), the growth rate (\(g\)) and the payment received right now (\(D_0\)), if any (leave empty otherwise):

Yearly Payment \((D)\) =
Interest Rate \((r)\) =
Growing Rate \((g)\) =
Amount paid now (if any, leave blank otherwise) \((D_0)\) =

Calculator of the Present Value of a Growing Perpetuity

More about the this growing perpetuity calculator so you can better understand how to use this solver: The present value (\(PV\)) of a growing perpetuity payment \(D\) depends on the interest rate \(r\), the growth rate \(g\) and whether or not the first payment is right now or at the end of the year. If the first payment of a perpetual stream of payments of \(D\) is made at the end of the year, we then have a regular growing perpetuity, and its present value (\(PV\)) can be computed using the following formula:

\[ PV = \displaystyle \sum_{n = 1}^{\infty} \frac{D \times (1+g)^{n-1}}{(1+r)^n} = \frac{D}{r-g} \]

On the other hand, if the first payment \(D_0\) is made now, then we have a growing perpetuity due, and its present value (\(PV\)) can be computed using the following formula.

\[ PV = D_0 + \displaystyle \sum_{n = 1}^{\infty} \frac{D \times (1+g)^{n-1}}{(1+r)^n} = D_0 + \frac{D}{r-g} \]

If you are trying to compute the present value of a perpetuity in which the yearly payment remains constant, use the following calculator of a regular perpetuity, or simply use \(g = 0\).
