I would also like this feature. Some examples:
- Different employees have different fringe rates. So an employee cost is base cost + (base cost * fringe rate)
- On top of the base cost, there is sometimes a markup on costs. This needs to be tracked in a separate column (because when we track budget vs actuals, the markup (profit) is not reflected in actual receipts). So, there's the fringed cost, but then there's also the marked up cost = fringed cost + (fringed cost * markup rate)
- For some employees, we charge a bench rate by hour, or by day, or by week. So on top of those other costs, there might be a bench rate that is separate, and needs to have the flexibility to be set by hour, day, or week
I could create custom columns, enter the % amounts, then export to excel to calculate. But that seems like an elaborate workaround just to do math.
