Compare building and leasing by pricing the same data-center service over the same period—not by setting construction cost beside one year of rent. Match usable IT capacity, location, redundancy, go-live date, and operational scope, then compare discounted annual cash flows, including who pays each cost. There is no universal break-even year: the result depends on local prices, power access, utilization, financing, schedule, and lease terms.
Define an equivalent data-center requirement
Before collecting prices, describe the service both options must deliver. Use a common set of assumptions for:

- Usable IT load in kW or MW, rack density, expected load profile, and utilization ramp.
- Redundancy, availability obligations, security and compliance requirements, and network connectivity.
- Location or market, target go-live date, evaluation period, and the party responsible for operating the facility.
Installed capacity that sits unused still carries a cost. Microsoft’s Azure Migrate facilities-cost example accounts for unused capacity, but its assumptions are tool-specific rather than industry standards: Microsoft Learn’s facilities-cost methodology.

Lease products bundle responsibility differently. Hogan Lovells distinguishes wholesale data-center space, powered shell, colocation, managed hosting, and cloud; these are not interchangeable cost bundles. Confirm whether the provider supplies only space and power or also fit-out, equipment, operations, and managed services before comparing prices. Contract and legal terms also depend on jurisdiction. See Hogan Lovells’ guide to building or leasing a data center.

Build a like-for-like cost inventory
For each scenario, mark every line as paid by the owner, tenant, or operator; identify what is included in the quote and what is excluded. Avoid treating a base-build estimate as the cost of an operational facility.
| Cost area | Build and own | Lease or colocation |
|---|---|---|
| Initial facility costs | Land or site acquisition, planning, design, permits, civil works, shell, electrical distribution, cooling, fire protection, security, commissioning, and tenant or white-space fit-out. | Tenant fit-out or installation where required, deposits, setup charges, and any equipment the tenant must buy. |
| Power and connectivity | Utility connections, substations, fiber, electricity, and cooling energy. | Base rent or committed power charges, metered or passed-through electricity, energy or cooling surcharges, and cross-connects. |
| Operations and obligations | Financing and carrying costs during construction, staff, maintenance, insurance, taxes, equipment refreshes, and decommissioning. | Remote hands or managed services, minimum commitments, rent escalators, taxes, renewal and exit costs, and continuing tenant-side staffing or maintenance. |
| End-of-period value and risk | Potential residual asset value; owner retains construction, operating, and end-of-life exposure. | Renewal, escalation, provider, and exit risks under the contract; tenant-owned equipment may retain value. |
Scope differences can be substantial. KPMG’s 2026 construction benchmark is for base build and excludes tenant fit-out, substations, fiber connections, and other work outside the builder’s scope; it is not an all-in project price. The scope is described in KPMG’s data-center report and its 2026 report PDF.
A lease calculator can help expose omitted categories, but it is not a bid. Datacentres.com’s illustrative estimate separates power, colocation, and cross-connects and notes that actual costs vary by provider, configuration, contract, and location. Its inputs include power, market, rack count, contract term, redundancy, and cooling efficiency: Datacentres.com’s data-center cost calculator.

Rank #2
- Save valuable floor space: 12U wall mount server cabinet Dimensions: 24.25" H x21.65" W x17.72" D. MAXIMUM MOUNTING DEPTH is 14.2".
- Keep critical network equipment secure: glass door and side panels are lockable to prevent unauthorized access; Front door can be installed on either side of the front of the cabinet to satisfy your door swing orientation preference

- PCI & HIPPA and EIA/ECA-310-E compliant
Put both options on the same financial basis
- Set the horizon and discount rate. Use the same evaluation period and cost-of-capital assumption for both cases.
- Model annual cash flows. Include construction timing and financing, lease start and rent escalators, ramp-up, energy, staffing, maintenance, refresh cycles, taxes, insurance, and end-of-term costs.
- Account for value at the end. Estimate residual or salvage value for owned assets and include decommissioning where relevant; model lease renewal or exit costs rather than assuming the contract ends cleanly.
- Report net present cost and yearly cash flow. State whether figures are nominal or real, and disclose inflation, energy-price, tax, and utilization assumptions.
Keep the comparison in a consistent currency and scope. A build’s capital outlay occurs before service begins, while rent and many operating costs recur; comparing build capex with one year of lease expense will misstate the economics.
Use benchmarks carefully
KPMG’s 2026 report gives sampled European base-build construction estimates of $8.5 million per MW in the UK and $6.7 million per MW in Spain, a reported 26% difference between those markets. These are base-build figures—not complete project costs—and should not be generalized to other regions, project scopes, or delivery dates. Use them as context, then obtain local engineering estimates and utility, land, and contractor quotes.
Other published numbers answer different questions. Schneider Electric reports 30% total-cost-of-ownership savings for standardized, scalable, preassembled power and cooling modules compared with traditional built-out power and cooling infrastructure. That is a vendor claim about infrastructure design, not a build-versus-lease result: Schneider Electric’s TCO discussion.

Test what could change the result
Build a base case, then vary the assumptions most likely to alter the ranking:
- Shorter and longer occupancy periods.
- Lower and higher utilization, load growth, and capacity ramp.
- Construction delay, cost overrun, and financing rate.
- Energy-price changes and lease escalation.
- Power availability and the date capacity can actually be energized.
Power access and schedule are economic variables, not just engineering details: a nominally cheaper site is not useful if it cannot deliver the required service on time. JLL’s 2026 outlook forecasts an additional 62 GW in leased data-center capacity, including colocation and build-to-suit, from 2026 through 2030; this is a market forecast, not evidence of savings for any one project. The outlook also describes power availability as critical to project success and growth in both leased and self-built capacity: JLL’s 2026 data-center outlook.
Online calculators are useful for screening and identifying inputs, but local contracts, engineering estimates, and utility schedules are needed for a project decision.
Compare the non-price trade-offs
| Dimension | Build and own | Lease or colocation | What to check |
|---|---|---|---|
| Initial capital | Usually requires land, design, construction, fit-out, equipment, and financing. | Facility capital may be lower, though fit-out and tenant equipment can remain the tenant’s responsibility. | Same capacity, service scope, and start date. |
| Control | Greater potential to customize design and operations. | Control varies by product and contract. | Redundancy, security, operating responsibility, and compliance needs. |
| Time to capacity | Depends on planning, construction, commissioning, and utility delivery. | Can offer earlier access if suitable capacity and power are available. | Credible go-live date and confirmed power availability. |
| Scaling and utilization | Risk of building capacity ahead of demand. | Capacity may be contracted incrementally, subject to availability and minimum commitments. | Ramp assumptions, contract minimums, and expansion rights. |
| Long-term exposure | Owner keeps asset value and construction and operating risks. | Tenant faces contract, renewal, escalation, provider, and exit risks. | Same horizon, discount rate, and end-state assumptions. |
JLL describes both leased and owner-occupied capacity strategies and an ongoing role for hybrid deployments; a company need not treat the decision as all-build or all-lease. See JLL’s outlook.
