GPU Server & Data Center Electricity Cost Calculator
Estimate continuous power consumption, monthly and annual electricity costs, and heat dissipation for GPU server deployments.
How to Use This Calculator
- Enter the number of GPU server nodes and the rated or measured power draw per node.
- Select the Power Usage Effectiveness (PUE) representing your data center cooling efficiency.
- Enter your local commercial electricity tariff to review annual operating costs and required cooling capacity.
Frequently Asked Questions
What is Power Usage Effectiveness (PUE)?
PUE is the ratio of total facility power to the energy consumed directly by IT equipment. A PUE of 1.25 means that every 1 kW of server draw requires an extra 0.25 kW for cooling and infrastructure.
Why does electricity cost matter so much over a server lifecycle?
Over a 3- to 5-year production lifecycle, continuous electricity consumption can match or exceed the initial hardware capital expense, especially in high-density compute environments.
How is required cooling capacity calculated?
Electrical power consumed by computer hardware is converted almost entirely into heat. One kilowatt equates to approximately 3,412 BTU/h, and 12,000 BTU/h corresponds to one ton of refrigeration cooling.
Planning note: Results are planning estimates. Actual memory consumption, throughput, and power draw depend on inference runtime implementation (e.g. vLLM vs llama.cpp), batch size, and sequence context length. Benchmark your specific workload on physical hardware before purchasing.
