How to Calculate Data Center Energy Costs?

In the hosting industry, costs are often discussed in "Amps", but electricity bills are paid in "kWh". To calculate this correctly, the formula is: **(Amps x Volts) = Watts**. Divide the resulting Watts by 1000 to get kW.

For example; a server drawing 1 Amp (220V) consumes 0.22 kW per hour. If this server runs 24/7 for 30 days, it consumes approximately **158.4 kWh**. However, this is just the server load. Cooling costs (PUE) will increase the bill.

How many Watts is 1 Amp?

In Europe and Turkey standards (220V), **1 Amp ≈ 220 Watts**. In US standards (110V), this value is 110 Watts.

Why is PUE Important?

PUE (Power Usage Effectiveness) is the efficiency scorecard of a data center. A value of 1.0 represents a lossless (ideal) environment. The average is between 1.5 - 1.7. This means if your server burns $100, another $50 is spent on cooling.

Frequently Asked Questions

How many Amps do I need for Colocation?

An average Dell R740 or HP DL380 server consumes between 0.8 and 1.5 Amps under load. However, servers with GPUs can reach 4-5 Amps. The best method is to check instant consumption from iDRAC/ILO.

Is this tool 100% accurate?

This tool relies on mathematical formulas (Ohm's Law) and works with 99% accuracy. However, voltage fluctuations in the data center (e.g., receiving 218V instead of 220V) or PUE changes may cause a +/- 1% deviation.
