MACC Rates & Billing

University of Michigan MACC tenants have access to detailed billing statements. Click here to review this information. University of Michigan affiliated MACC tenants should contact the DCO Services to request billing information.

The MACC is owned by the university and operated by the ITS Data Center Operations staff. 

Units are responsible for paying a fair portion of the fixed and variable costs for the space and electrical costs they incur. 


Item Billing Code Cost
Rack Space (fixed) MAC-RACK $366.67/month/rack
Electrical (variable) MAC-ELECT varies per kilowatt hour/month

Fixed Costs vs. Variable Costs

Fixed cost rates cover the annual rack rate for staffing, rent, maintenance, replacement of mechanical systems, and basic network connections. 

Note: The Provost’s subsidy offsets a portion of fixed costs for all university MACC customers.

Variable cost rates include:

  • The actual cost of the electricity consumed by rack(s) as measured by the Foreseer Monitoring Database, and
  • The cost of electricity used in rack(s) multiplied by a 2.6 cost recovery factor that covers a proportional share of the facility’s environmental infrastructure electrical usage costs.

Additional Funding for the MACC

The MACC was initially funded by the Regents and sponsored by the Provost’s Office. Provost sponsorship included initial funding for the construction, and an ongoing annual operational subsidy to incent university units to work cooperatively within shared data center facilities.


Once fixed and variable charges are calculated, they are aggregated by rack and customer and billed at a unit level monthly via the University Service Unit Billing System. Units may, in turn, bill individual customers for their portion of this bill. 

ITS tracks these electrical usage and charges on a monthly basis and publishes a Billing Detail document that calculates the charges for each customer. 

Billing begins on the month that a customer draws electricity in the MACC for their equipment.
