Enter the total number of servers, power consumption of each server, average run time per day, and the electricity cost into the calculator to determine the server room cost.

Server Room Cost Formula

The following formula is used to calculate the cost of a server room (power cost only).

SRC = #S * PC/1000 * EC * T

  • Where SRC is the server room cost to run ($/day)
  • #S is the total number of servers
  • PC is the power consumption of each server (watts)
  • EC is the cost of electricity ($/kWh)
  • T is the total time the servers run per day (hrs)

To calculate the server room run cost, multiply the number of servers by the power consumption of the servers, by the average run time per day, then finally by the cost of electricity.

What is the cost to run a server room?

Definition:

A server room cost is typically considered the daily electrical cost of a server room and omits upfront server costs and overhead costs.

How to calculate a server room cost?

Example Problem:

The following example outlines how to calculate the cost of a server room.

First, determine the total number of servers. In this case, there are a total of 500 servers.

Next, determine the power consumption of the servers. These servers consume 10 watts.

Next, determine the average time the servers run per day. In this case, the servers run all day long, so 24 hours.

Next, determine the electricity cost. The local cost of electric in this area is found to be .785 $/kWH.

Finally, calculate the server cost using the formula above:

SRC = #S * PC/1000 * EC * T

SRC = 500* 10/1000 * .785* 24

SRC = $94.2 /day
