Urgent Unable to create amortization table in Power BI

Hi Everyone, 


I am trying to create an amortization table in power bi from a database.


In the database, I have mortgage balance, Account and Term Interest Rate. Currently, loan database only has the payments made in prior months. The user is unable to see entire Loan amortization table. 


I have created a date Dimension but I don't know how to generate an entire amortization table.

If I can get help in generating a table with future dates until MtgBalance becomes zero that would be a great help. 


Thank you in advance.

I have the same question .....


I wish someone can shed some light , it be great help 


FYI our firm made the decision this afternoon to move away from Power BI since it cannot handle mortgage amortization tables within the app itself. Good luck.




OK, I created it this way:


First, create Measures for P, n and i like this:


n = 360
n = 0.05
P = 250000
Payment = [P]*(([i]/12)*POWER(1+([i]/12),[n]))/(POWER(1+([i]/12),[n])-1)

Then, create a Table with this formula:


Mortgage = GENERATESERIES(0,[n],1)

Now create the following columns:


Balance = [P]*(POWER(1+[i]/12,[n])-POWER(1+[i]/12,[Value]+1))/(POWER(1+[i]/12,[n])-1)

MonthlyInterest = ([i]/12)*[Balance]

MonthlyPrincipal = [Payment]-[MonthlyInterest]

MonthlyPayment = [Payment]

I will do some work on this and see if I can get this to be truly dynamic but let me know if this is along the lines of what you are looking for.

Hi, Can you show Data Sample and the Way that you want the result.


I'm not familiarized with mortgage Calcs.

That would be a great help, I have the mortgage formula measure already made.


Thank you Greg. I appreciate your response. If there was a way to be able to input variables into that table we would be good, but I can't find a way to do that.




Hi Greg

I do not have the value of n  but I was able to create the Mortgage Interest Rate, Monthly payments, and the Balance field because I can get the loan amount, Interest rate,  first loan payment date from the database but I need to generate entire amortization table with future dates. So essentially I would like to get future dates until Balance becomes zero. 




If you look at the screenshot I have pasted current table and future table, in future table I have added the two rows below and I would like to see dates repeating every month in the future until mortgage balance becomes zero.
