Weighted Average Interest Rate (by Seller) DAX Formula

[th340385]

Hello,

I am trying to figure out the DAX formula (or best approach) to calculate the weighted average interest rate by loan seller with the ability to add a slicer / filter on vintage. Please let me know if you need any additional details. 

Thank you!

@th340385I did it in this way. Hopefully this is what you are looking for.

Total Balance = SUMX('Table (2)','Table (2)'[Balance])
BalancexRate = SUMX('Table (2)','Table (2)'[Balance]*'Table (2)'[Rate])
WEGH_Avg_INT% = [BalancexRate]/[Total Balance]

@smpa01 Thank you for the reply. The formulas provide for each column make sense; however, how did you initially summarize the data by the Loan Seller Column?

[th340385]

@smpa01 Actually, I believe you used a matrix visualization, correct?

@th340385used a matrix viz and all my calculations are measures and not calculated column.

If it is dependent on Loan Bal. Approach could be

Col = Loan Bal * Int. rate 

Weighted Avg = Sum(Col)/Sum(Loan bal)

Thanks for this! This was the first simplistic option I had come across and it worked perfectly
