I'm trying to calculate the Total Time in hours and minutes to complete a job. The way we are calculating it is by taking the Fee paid and dividing that by a 1:00.

In Excel - Marsh is charged $90.00 (This is pre-determined)
Her job is a $25.00/hour job (This is pre-determined)
The Raw Hours to complete the job is 3.6 hours (I have this already in
a qry)
the Total Time to complete the job is 3:36. (Can't figure out how to get
this.

Not that I used the Backslash in the first half of the expression. The Backslash only returns the Integer portion of the division, the 3 in your example.

Hi. The 3.6 is the time in hours expressed as a decimal value. It is derived as the ratio of the fee paid to the hourly rate:

3.6 = 90 / 25, generalised to

[Time in Hours Decimal] = [Fee Paid] / [Hourly Rate]

The 3:36 you mention is the time expressed in hours and minutes:
3.6 hours converted to hours and minutes =
3.6 * 60 minutes = 216 minutes = 3 hours and 36 minutes.

As the times you are referring to are not clock times - it is simply a total for hours:minutes, not a time of day - I would suggest that it is best to work in total minutes if you have any further calculations, or separately in hours and minutes if you don't, then combine back to hours and minutes for final presentation if need be.

The calculations are as follows.

If working in total minutes (should you need to do any other calculations such as adding the total hours from different jobs):
