How to use mark up instead of Bill rate for revenue generation

Hi,

I have setup the bill rate schedule for non labor expenditure items with expenditure types, instead of a particular rate, i have specified the mark up percentage as 10% so when i charge an expenditure using the expenditure type what would be the calculation.

Basically i am charging using the expenditure type as below

Expenditure Type - A

Quantity per expenditure item - 10

Bill Rate - None/Blank

Mark Up percent - 10

so what would be the calculation using mark up percent for 10 quantity? Also what will be accrued revenue?
