Hosting Cost Calculator

Colocating miners at a hosting facility shifts the electrical, cooling, and rack-space burden onto someone else's building, but that convenience is billed back to you — this calculator lays out exactly how. It starts from raw power draw (number of miners × watts per miner, assumed to run continuously) and converts that into a 24/7, 30-day electricity bill at the facility's quoted rate. On top of that base electricity cost, it layers a management fee — calculated as a percentage of the electricity charge itself, not a flat fee — which covers the host's monitoring, maintenance, and facility overhead; this is a common structure in real hosting contracts, though some facilities instead charge a flat per-miner fee, so check your actual contract terms against this model.

A one-time setup fee per unit covers installation and is amortized separately into the total contract cost alongside the recurring monthly charges across your chosen contract length. The tool also estimates rack space needed by dividing total rack units required by the standard 42U rack height and rounding up, and reports an "effective rate" — your true all-in cost per kWh once the management fee is folded in — which is the number to compare against a self-hosted setup's raw electricity rate, not the facility's quoted headline rate. Common mixups: this model doesn't account for facility cooling overhead baked into the per-kWh rate (some hosts include it, some bill it separately), noise/downtime SLAs, or bandwidth fees, all of which can materially change the real cost of a hosting contract.
