# Present Value (PV) of an annuity due calculator

LAST UPDATE: April 8th, 2018

### What is a Present Value (PV) of an annuity due?

Present value (PV) of an annuity due is a financial calculation used when determining the “today” value of a set of annuity payments that occur each compounding period, when the payments occur at the beginning of the compounding period (as opposed to a regular annuity, where the payments occur at the end of the compounding period).
As this calculator is structured to parallel the results of a financial calculator, inputs and outputs will be similar – for example, a negative present value (or payment) means an outflow as opposed to a directly negative number.

### How is the Present Value of an Annuity Due calculated?

The PV of an annuity due is calculated through a financial formula used with the time value of money.
$\text{Present Value} = (\frac{\text{Annuity Payment}}{Interest Rate}) \times (1 - \frac{1}{(1 + \text{Interest Rate})^\text{Number of Periods}}) \times (1 + \text{Interest Rate})$
