GPU Colocation vs Onsite Calculator: Rack Fees or Facility Buildout
This free GPU colocation versus onsite calculator compares paying monthly colocation rack fees against building your own facility for GPU hosting, and it is built for IT directors weighing where to physically place a GPU cluster. Enter GPU count, rack density, colocation pricing, and onsite buildout and operating costs, and the tool returns total cost under each path over your planning horizon plus the payback period for building onsite. The right answer depends heavily on how long you plan to run the hardware and whether your organization already has usable power and cooling capacity.
Your numbers
GPUs to be housed either in colocation racks or in a facility you build yourself.
Density depends on cooling: air-cooled racks fit fewer GPUs than liquid-cooled racks at the same power budget.
Includes power up to a contracted kW draw, cross-connect, and remote-hands support at a typical facility.
Electrical service, cooling infrastructure, and physical build-out capex, allocated per rack.
Power, facility maintenance, and allocated staff time, excluding the upfront buildout capex.
Your results
Planning estimates only. Colocation quotes vary widely by market and power density, and onsite buildout costs depend heavily on your existing facility. Get quotes from at least two colocation providers before committing to either path.

How the comparison works
Colocation trades a large upfront capital cost for a predictable monthly fee: no electrical or cooling buildout, but a recurring bill for as long as the hardware runs. Onsite trades the opposite: a significant facility investment upfront, offset by a lower ongoing operating cost once the capex is sunk. Four racks of 8 GPUs each at $2,200 per month plus a $5,000 setup fee comes to roughly $548,000 over five years in colocation fees. The same four racks built onsite at $45,000 per rack buildout plus $600 monthly opex comes to about $324,000 over the same horizon, favoring onsite once the facility investment is justified by a long enough runway.
When colocation wins and when onsite wins
Colocation typically wins for shorter time horizons, pilots, and organizations without spare electrical or cooling capacity, because it avoids a large capital outlay and a multi-month facility project. Onsite typically wins for long-term, high-utilization deployments where the organization already has usable power and floor space, since the buildout capex amortizes across many years of lower ongoing cost.
- Colocation avoids electrical permitting, cooling installation, and facility project timelines that commonly run 12-20 weeks.
- Onsite gives full physical control, which regulated customers with ITAR or CMMC data often require regardless of cost.
- Colocation monthly fees typically include remote-hands support, which reduces the need for on-call facilities staff.
- Onsite buildout costs vary enormously depending on whether you are retrofitting existing space or building new.
Reading your breakeven number
If breakeven months is well inside your planning horizon, and colocation's monthly fee exceeds onsite's ongoing opex, building onsite is the financially stronger choice as long as you can absorb the upfront capital and tolerate the buildout timeline. If breakeven extends past your horizon, or if regulatory requirements mandate colocation-grade compliance certifications you cannot replicate onsite, colocation is the more practical path even if it costs more over a long horizon.
How Netray helps you decide between colocation and onsite
Netray helps manufacturers weigh colocation against onsite builds against the specific compliance and timeline constraints that generic cost comparisons miss, particularly ITAR and CMMC requirements that can rule out shared colocation facilities regardless of price. We model total cost against your real planning horizon and facility condition, then manage whichever path you choose, from colocation contract negotiation to onsite facility project management. Engagements typically start with a facility and compliance assessment before a recommendation is made.
Frequently Asked Questions
Does colocation satisfy ITAR or CMMC data residency requirements?
It can, but only with a facility that carries the right certifications and contractual controls, and even then the shared nature of many colocation facilities raises questions some assessors will scrutinize closely. Some regulated manufacturers use colocation successfully with a dedicated, access-controlled suite; others conclude that onsite is the only path that satisfies their specific customer flow-down requirements. Confirm this with your compliance team before choosing colocation for controlled data.
What is typically included in a colocation monthly rack fee?
Most colocation contracts bundle power up to a contracted kilowatt draw, physical rack space, basic cooling, network cross-connects, and remote-hands support for simple tasks like power cycling a server. Bandwidth, additional power beyond the contracted tier, and complex remote-hands work typically bill separately, so get an itemized quote rather than assuming the headline monthly fee is the full cost.
How long does an onsite GPU facility buildout typically take?
For a modest retrofit adding electrical capacity and cooling to an existing server room, expect roughly 8-16 weeks including permitting and contractor scheduling. A larger new build with significant electrical service upgrades can take 20-40 weeks. Colocation, by contrast, can often be provisioned in 2-6 weeks once a contract is signed, which is the main reason organizations under time pressure default to it even when onsite would be cheaper long-term.
Can we start with colocation and move onsite later?
Yes, and it is a common pattern for organizations still validating whether an AI workload justifies a permanent facility investment. Start in colocation to prove out the workload and avoid a premature capital commitment, then build onsite once utilization and business value are established and the long-term cost savings clearly justify the buildout project.
