Calculate frequency using pre-determined formulae

Hi, IanT76 

I'd like to suggest you create a measure as below.

Result = 
var _month = SELECTEDVALUE('Table'[Month])
return
(
    200000*
    CALCULATE(
        SUM('Table'[FAC's]),
        'Table'[Month] = _month
    )
)/
CALCULATE(
    SUM('Table'[Hours Worked]),
    'Table'[Month] = _month
)

Result:

Best Regards

Allan
