Data center yield on cost (YoC) is forecast annual net operating income (NOI) divided by a stated measure of total project investment. For a development, the numerator is often expected stabilized NOI. The percentage is meaningful only when the cost boundary and NOI assumptions are clear; it is a forecast property-level yield, not an investor’s realized return.
How do you calculate data center yield on cost?
YoC = annual NOI ÷ total project cost. Multiply by 100 to express the result as a percentage. For example, a hypothetical project costing $100 million on a defined basis and generating $10 million of annual NOI on that same basis has a 10% YoC. This is arithmetic, not a market benchmark.

NOI means operating income after property operating expenses, rather than revenue or EBITDA. In a data center, expenses can include energy, water, and staffing. State whether the numerator is current NOI, a run-rate estimate, or forecast stabilized NOI. For a development, stabilized NOI is a projection; it may be based on signed leases or assumptions about future market rents and occupancy. Digital Realty’s 2025 presentation describes estimated stabilized cash yields using anticipated NOI and total expected investment.
What costs belong in the denominator?
There is no single mandatory industry-wide accounting definition of YoC established by the sources cited here. “Total project cost” can mean different things, so name the included costs rather than presenting a partial basis as all-in.
A useful cost checklist includes:
- Land or acquisition cost
- Site preparation and power or other infrastructure
- Building shell
- Direct data-center fit-out
- Soft costs, contingency, and other development expenses
- Financing costs, if included in the chosen basis
For example, Digital Realty defines total data-center development cost to include acquisition, infrastructure, shell space, and direct data-center fit-out investment. An industry explainer also treats construction-loan financing cost as a project-cost consideration. These approaches make it especially important to disclose whether financing and other costs are counted. Digital Realty’s stated scope is an issuer definition, not a universal rule; the industry explainer sets out its own practical treatment.
Should you include interest or financing costs?
There is no universal answer independent of the definition being used. Include financing costs if the chosen project-cost basis includes them, and identify them explicitly. If they are excluded, say so. Most importantly, do not mix a denominator that includes financing costs with a numerator that is actually an equity-level return or post-debt cash flow and then label the result property YoC.
A simple YoC ratio does not model debt service, the timing of capital deployment, or the eventual sale proceeds. It therefore cannot replace a levered equity return calculation or a time-phased project IRR.

A cap rate relates a property’s annual NOI to its market value or price. Development underwriting often compares expected stabilized YoC with a relevant market or exit cap rate. The difference—YoC minus the cap rate—is commonly called the development spread. A positive spread can indicate potential value creation in the development case, but it is a screening lens, not proof that the project will be profitable.

Brookfield Infrastructure Partners said in its Q4 2024 unitholder letter that returns to buyers for its stabilized assets were “3-4% below our yield-on-cost.” That is a company-specific observation about its portfolio and transactions, not a universal target spread.

Even a seemingly attractive spread can narrow or disappear if construction costs rise, leasing takes longer, operating expenses exceed forecasts, power delivery is delayed, or exit pricing weakens. Assess those risks separately rather than treating the spread as a guaranteed development profit.
Why data center YoC estimates can change
Leasing and operating income
Forecast NOI depends on customer demand, contract pricing, occupancy or utilization, and the operating costs borne by the owner. Lease length and tenant credit also affect the reliability of projected income. A figure based on signed leases is not directly comparable with one that assumes future market demand unless that difference is made explicit.

Development costs, power, and timing
If final project costs exceed the underwriting estimate without a corresponding increase in NOI, YoC falls. Power availability and permitting can affect whether a project is deliverable on schedule, while delays can also alter the financing and stabilization timeline. In CBRE’s 2025 Global Data Center Investor Intentions Survey, conducted in early 2025, 39% of respondents cited regulations and power availability as a key investment challenge. That is a survey response, not a probability that any particular project will fail. CBRE’s 2025 survey
Market expectations are not realized outcomes
The same CBRE survey found that 62% of respondents favored opportunistic or new-development strategies; 28% expected initial yields or cap rates to increase, while 53% expected no change. These figures record investor intentions and expectations in 2025. They are not realized investment outcomes, a 2026 sentiment reading, or a benchmark YoC for a project.

Before ranking projects, align the assumptions that can make their headline percentages look comparable when they are not:
- Cost boundary: Confirm whether land or acquisition, power and site infrastructure, shell, fit-out, soft costs, contingency, and financing are included.
- Income definition and timing: Compare property NOI with property NOI, and distinguish in-place income from forecast stabilized NOI. Identify whether forecast leases are signed or assumed.
- Capacity basis: Check whether capacity is expressed as gross MW or critical/IT MW. Determine how existing infrastructure is valued or treated as a sunk cost; a site with valuable existing infrastructure is not mechanically comparable with a greenfield development. TeraWulf’s presentation illustrates the significance of existing site infrastructure.
- Lease and operating assumptions: Compare tenant credit, contract duration, rent, occupancy or utilization, energy pass-throughs, and owner-paid expenses.
- Execution and market context: Align geography, permitting, power-delivery timeline, construction schedule, stabilization date, and the relevant market or exit cap rate.
- Return measure: Separate an unlevered property yield from a levered equity return. Consider debt costs, repayments, and the timing of capital separately.
How to interpret issuer examples
Company illustrations can show how an issuer uses the term, but their assumptions should not be mistaken for market-wide costs or targets. Jet.AI’s SEC-filed document gives an illustration of approximately $10 million in construction cost per MW and roughly $1 million in NOI per MW, describing that as a 10% yield on construction cost. The company labels the denominator as construction cost, not necessarily all-in project investment; the figures are issuer claims, not independently established current industry averages.
