Hi everyone I am trying to find the cash percentage refund total in the following table in Power Bi, could someone please help with the formula, please
| Ticket | Total Sales | Percent | Refund |
| 5-15 | £210.00 | 48.00% | £100.80 |
| 16-20 | £520.00 | 75.00% | £390.00 |
Solved! Go to Solution.
Hi @pb14 ,
To calculate for each row in Power Query it would be:
[Refund] / [Total Sales]
To calculate over the whole table as a DAX measure would be:
DIVIDE(
SUM(yourTable[Refund]),
SUM(yourTable[Total Sales]),
0
)

Hi Pete thanks for this sorry the refund bit was what I am trying to find, I should have explained it better. so would it be
DIVIDE(
SUM(yourTable[percent]),
SUM(yourTable[Total Sales]),
0
)to find the refund value over the table
Yes. When applied as a measure this calculation will give you the total refund percent of sales over the whole table.
When you add further dimensions to the same visual (e.g. department etc.) it will auto-aggregate over just those added dimensions.
