To compare building a data center with leasing one, model both options over the same period and for the same usable IT capacity, location, redundancy, go-live date, and operating responsibilities. Compare discounted lifecycle costs—not a construction estimate against one year of rent—and test how the result changes with schedule, utilization, energy, financing, and contract terms. There is no universal break-even year: the lower-cost choice depends on the project and market.

First define what “leasing a data center” means

Leasing can describe different bundles of space, power, equipment, and services. A wholesale data-center lease, powered shell, retail colocation, managed hosting, and cloud service are not interchangeable cost options. Hogan Lovells describes these as distinct structures, with suitability depending in part on tenant size and requirements (Hogan Lovells, 2025).

Before requesting or comparing prices, choose the actual service model. In colocation, for example, a tenant may provide its own IT equipment while paying separately for space, power, connectivity, or services. A managed service or cloud offer may include responsibilities that remain with the customer under a facility lease. Compare only offers that deliver the same required outcome, and identify which party pays for and operates each component.

Set one shared service requirement

Write down the capacity and service each option must provide. Use the same assumptions for building and leasing:

  • Resilience: redundancy level, availability or uptime obligations, and the scope of backup power and cooling.
  • Location and connectivity: market, network requirements, fiber routes, and security or compliance needs.
  • Timing: required go-live date and credible dates for construction completion, utility service, and leased capacity availability.
  • Responsibility: who supplies IT equipment, operates the facility, handles maintenance, and meets service obligations.

Installed capacity that sits unused still carries a cost. Microsoft’s cloud-migration facilities-cost example accounts for unused capacity, but its embedded utilization and power assumptions are model-specific—not industry standards (Microsoft Learn).

Build a complete cost inventory

Separate one-time costs from recurring costs, and mark who pays each item: the owner, tenant, or operator. A headline construction figure may cover only part of the facility. KPMG’s 2026 benchmark defines its construction figure as base build and excludes tenant fit-out, substations, fiber connections, and other work outside the builder’s scope (KPMG report; KPMG cost definitions).

For a build-and-own scenario

  • Land or site acquisition, planning, design, permitting, and civil works.
  • Base construction, electrical distribution, cooling, fire protection, security, and commissioning.
  • Utility connections, substations, fiber, and other work outside the base-build scope.
  • Tenant or white-space fit-out and IT equipment.
  • Financing and carrying costs during construction, including the cost of a delayed opening.
  • Power, cooling, operating staff, maintenance, insurance, and taxes.
  • Equipment refreshes, residual or salvage value, and decommissioning where relevant.

For a lease or colocation scenario

  • Base rent or committed power charges, plus separately metered electricity or other pass-throughs.
  • Cooling or energy surcharges, cross-connects, installation, and fit-out.
  • Remote hands, managed services, minimum commitments, deposits, and any equipment the tenant still owns.
  • Escalators, renewal terms, taxes, and exit or removal costs.

Read the contract to determine what the quoted amount includes. The Datacentres.com calculator, for example, separates illustrative lease costs into power, colocation, and cross-connects and cautions that actual costs vary with provider, configuration, contract, and location (Datacentres.com calculator). Treat calculator results as screening estimates, not bids.

Use comparable benchmarks carefully

Geography affects both construction and operating costs. KPMG’s 2026 sampled European base-build estimate was $8.5 million per MW in the UK and $6.7 million per MW in Spain, a 26% difference between those reported markets. These are base-build benchmarks, not complete project costs, and should not be applied as all-in prices or generalized beyond their stated scope (KPMG report).

Design choices can affect total cost, but architecture comparisons do not answer the build-versus-lease question. Schneider Electric reports 30% TCO 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 finding that building is cheaper than leasing (Schneider Electric, 2023).

Put both options on the same financial basis

Choose one evaluation horizon and discount rate, then calculate annual cash flows and net present cost for each scenario. State whether your figures are nominal or real, and document the assumptions for inflation, energy prices, taxes, financing, and utilization. Include construction timing and ramp-up, lease increases, refresh cycles, residual value, and end-of-life costs.

Do not compare a lease’s annual operating expense with a build’s initial capital outlay. A build concentrates more spending up front and may leave an asset at the end of the period; a lease spreads payments but can include escalation and renewal or exit exposure. Assign costs to the party that actually bears them, rather than assuming every facility expense sits with the owner or every operating expense sits with the tenant.

  • Occupancy period: compare shorter and longer stays; a long horizon gives more time for a build’s capital investment to be used, but does not guarantee it will win.
  • Utilization and load growth: test slower and faster ramp-up, including the cost of unused built or committed capacity.
  • Construction delivery: model delay, cost overrun, and the financial impact of a later service date.
  • Energy and power: test energy-price changes and whether the required power is actually available on schedule.
  • Capital and contract terms: vary financing rates and lease escalators; include minimum commitments and renewal assumptions.

Use local engineering estimates and provider quotes for an investment decision. Online calculators help expose inputs but cannot substitute for project-specific scope, pricing, and contract review.

Compare operational fit as well as net present cost

Even a well-matched cost model does not capture every decision factor. Compare schedule, access to power, control and customization, expansion options, staffing expertise, compliance and security needs, facility or lease risk, and end-of-term asset value. A build generally involves more upfront capital and customization; leasing may provide earlier access when capacity is available and can shift some facility responsibilities. Those trade-offs vary with scope and contract.

Power is a constraint as well as a line item. JLL’s 2026 outlook describes power availability as critical to project success and forecasts an additional 62 GW for the leased data-center segment—including colocation and build-to-suit—from 2026 through 2030. This is a sector forecast, not a guarantee of local capacity or evidence that leasing saves money on a particular project (JLL, 2026).

A hybrid approach may suit organizations that need control over some workloads or capacity while using leased facilities for other needs. JLL discusses both leased and self-built capacity strategies and a continuing role for hybrid deployments (JLL, 2026). Model each part against its actual service requirement rather than treating hybrid as a single standard cost option.
