I am looking for a way to calculate the PV of rental streams in Power BI. This is a simple calculation in Excel (using the PV formula), but I have not found an easy way to complete this in Power BI. Has anyone done PV calculation in Power BI or found a work around for calculating PV of streams?
Hey @v-ljerr-msft XNPV does not work for what I need to do. I do not have streams table, but rather, it is a transaction/asset table that has a static rental over a specified number of periods which is why I would need PV. Very surprised that Power BI does not have the PV function available. Below is a single line item of my data. Total Revenue Net COF and 'NII' are calculated with PV which I am trying to get to in Power BI but I cannot seem to get there.
I have resolved this at work only moments ago, so I thought I'd share as I couldn't find the answer on here!
So firstly we use the formula that MS provides for what PV is:
Then we derive what a value for PV would look like:
So if we create a new table with rate, nper, pmt and a known-good value to compare to, we can work out this formula (knowing that type =0 for payments at end of term and that fv=0 if we are not specifying a future value outright):
PVColumn = (
( [pmt]*( 1+ ( ([Rate]/12.0)*0) ) )
( ( (POWER( (1 + ([Rate]/12.0) ), [nper]) ) -1)
(POWER( (1 + ([Rate]/12.0) ), [nper]) )
I have stored and linked the .pbix Proof of Concept file for you to look at on my personal site,
