Calculation of Costs

The factors which contribute to the cost of using a particular piece of equipment are as follows:

  • Capital investment (I): This is the cost of a piece of equipment, depreciated over 10 years.

  • Maintenance (M): This is the yearly cost of maintaining the equipment including periodic technical intervention by trained technicians, consumable parts, gas, water and electricity consumption.

  • Cleanroom support (CS): This cost is associated with the cost of the cleanroom including depreciation, maintenance, consumable materials and regular services such as garment cleaning and waste disposal. This cost is added only to equipment located inside the cleanroom or in the grey area.

  • House nitrogen (N): This is the cost associated with the use of house nitrogen. The machines are weighted according to their relative use of nitrogen during processing. This cost is not added to the rates quoted for equipment which do not use nitrogen.

In the calculation of the price of equipment use for the different types of users, the difference comes from the amount of the capital depreciation which is charged. National universities are not charged the depreciation costs whereas international companies are charged the full depreciation cost (international universities and national companies are charged a fraction of this cost). The other costs associated with equipment use are charged equally for all types of users.
