AI Data Center Power & Cost Calculator

How this is calculated

1. 1. GPU load

   GPU load (kW) = GPU count × GPU power draw at full compute load (W) × utilization ÷ 1000

   Utilization is used here as a simplified linear scaling factor on top of the GPU's power draw at full compute load — not a measured power curve. In reality, GPUs draw meaningful power even at idle, and real power draw does not necessarily scale linearly with utilization. This model ignores both effects, so the result is a planning approximation, not a measured or guaranteed load.

2. 2. Total IT load

   IT load (kW) = GPU load × (1 + additional IT overhead %)

   IT overhead accounts for CPUs, memory, storage, networking, and power supplies around the GPUs themselves.

3. 3. Facility load

   Facility load (kW) = IT load × PUE

   Power Usage Effectiveness (PUE) captures the overhead of cooling, power distribution losses, lighting, and other non-IT facility draw. A PUE of 1.3 means for every 1 kW delivered to IT equipment, the facility draws 1.3 kW at the meter.

4. 4. Energy consumption

   Daily energy (kWh) = Facility load (kW) × hours operated per day
   Annual energy (kWh) = Daily energy × operating days per year
   Monthly energy (kWh) = Annual energy ÷ 12

   Calculation convention: monthly figures are always annual energy divided by twelve, not daily energy multiplied by a fixed day count. This keeps the monthly and annual numbers internally consistent regardless of how many days per year you enter.

5. 5. Electricity cost

   Annual cost = Annual energy (kWh) × electricity price per kWh
   Monthly cost = Annual cost ÷ 12

   Cost uses a single flat electricity price you provide. It does not model tiered pricing, demand charges, or currency conversion — QAR and USD are treated as independent input currencies, not converted between each other.

Input bounds and validation

Every field has a stated, realistic range, and GPU count and operating days per year must be whole numbers. If any field is empty, out of range, or otherwise invalid, the calculator shows which fields need correction instead of guessing on your behalf — it never substitutes a default or rounded value for something you typed, so a result you see always corresponds exactly to the values shown in the fields. The shareable link only updates once every field is valid, for the same reason. If you've opened a shared link, the calculator reads its values as soon as the page loads in your browser — you may see a brief "Loading calculator…" message rather than a result computed from the wrong numbers while that happens. Your inputs are never sent to a server or stored anywhere outside your browser's address bar — the calculator runs entirely client-side, and the only persistence is that optional, human-readable query string.
