Pmt = FV x i / ((1 + i)( (1 + i)n - 1 ))
FV = Present Value
Pmt = Periodic payment
i = Discount rate
n = Number of periods
This annuity due payment formula FV calculates the annuity payment required to provide a given future value (FV). The annuity due formula assumes payments are made at the start of each period for n periods, and a discount rate i is applied.
The annuity due payment formula FV can be used for example, to calculate the periodic deposits needed at the start for each period to provide a required savings account balance (FV), given the number of deposits (n), and the account interest rate (i).
The Excel PMT function can be used instead of the annuity due payment formula FV, and has the syntax shown below.
PMT(Rate, Nper, PV, FV, Type)
*In this instance, the PV argument is not used when using the Excel Annuity due payment function.
Example Using Annuity Due Payment Formula FV
An investor wants to save an amount of 8,000 by depositing regular annuity payments at the start of each period for 15 periods at an interest rate of 4% per period. The amount of the annuity payment is given by the annuity due payment formula FV as follows:
Annuity payment = Pmt = FV x i / ((1 + i)( (1 + i)n - 1 )) Annuity payment = Pmt = 8000 x 4% / ((1 + 4%)( (1 + 4%)15 - 1 )) Annuity payment = Pmt = 384.16
The same answer can be obtained using the Excel PMT function as follows:
Annuity payment = PMT(Rate, Nper, PV, FV, Type) Annuity payment = PMT(4%,15,,-8000,1) Annuity payment = 384.16
