Make your assumptions
work harder.
A transparent planning model for comparable compute units. Enter your own assumptions, explore energy and operating costs, and download a brief.
The formula stays visible.
This model is a starting point for questions, not an engineering design or a full ownership-cost assessment.
Scheduled unit-hours = units × hours/day × days
Active unit-hours = scheduled unit-hours × active load
IT energy (kWh) = scheduled unit-hours × average system kW
Facility energy (kWh) = IT energy × PUE
Electricity estimate = facility kWh × electricity rate
Cloud illustration = scheduled unit-hours × cloud unit-hour rate
Electricity uses powered hours and average whole-system draw; active load changes the work-hours estimate, not energy. Set average power to reflect your own load profile. These estimates exclude hardware purchase, financing, software, staff, networking, storage, data transfer, taxes and support. Electricity and cloud totals have different cost boundaries and do not establish a financial winner. No performance equivalence, available capacity or vendor quotation is implied.
