Help Spreadsheet formula required

I have a spread sheet that I have worked from for years to update pricing that is formula based. I need to add a new field to add a hidden mark up between the actual cost price and the cost plus field that others will see. The cost plus field will then act like a base price that the other price levels are calculated from. Simple to this point. My problem lies were I need to add a mark up in the cost plus field but do not wish to increase the current calculated price levels by the same amount.

I have attached a sample spread sheet.

If anyone can help it would be really appreciated.

Does this work for you ?
