How much does it cost to build a data center in the USA in 2026?

Ask five people what a data center costs and you will get five different answers, and most of them will be right about a different building. One person is counting the shell. Another includes land and the utility connection. A third adds the servers. The number only makes sense once you know what is inside it.

This guide sticks to construction and development cost, using figures published in 2026, and says plainly what each figure covers. Cost data for this sector moves fast, so treat everything here as a snapshot from November 2026 and check the dates before you reuse a number.

Why data center costs are quoted per megawatt

Houses and offices get priced per square foot. Data centers usually don’t, because floor area says very little about what a facility costs. A hall packed with high-density racks needs far more power and cooling than a hall of the same size running light loads. Capacity in megawatts tracks the expensive parts, which are the electrical and cooling systems, so the industry prices per MW of IT load.

You will still see cost per square foot in search results. It is fine for a rough comparison between similar buildings. It breaks down fast when power density differs, which is most of the time.

What the 2026 numbers say

The most useful recent public reference is the Cushman & Wakefield 2026 Data Center Development Cost Guide, published in September 2026. Here is what it reported for the United States and Canada, along with one Census data point that explains why costs are under pressure.

The width of that first range is the real story. A project at the low end and one at the high end can differ by more than two and a half times, and both can be accurate. The Census figure comes from the monthly spending tables, and Tom’s Hardware covered it, including the note that Census does not count the servers and racks.

Why one project costs twice as much as another

A few decisions account for most of the spread. Power density per rack sets the size of the electrical gear. The cooling approach matters a lot: air cooling and liquid cooling need different piping, pumps and heat rejection. The redundancy level decides how many generators, UPS modules and cooling units you build in order to keep one failure from taking the hall down. Then there is location, which drives labor cost and also how long you wait for utility power.

Site conditions and structure play a smaller part. Soil, grading and seismic design can move the number, but the cost of the building envelope is rarely what separates a $9M per MW project from a $23M one.

What is usually left out of a per-MW figure

Before you compare two numbers, ask what each one leaves out. Common exclusions are land, utility interconnection and upgrade charges, the IT equipment itself, owner soft costs such as design and permitting, financing, and escalation to the actual construction date. A contractor’s construction number will normally sit below an all-in development figure for exactly these reasons.

Building a budget number for your own project

If you are early and only need a planning range, work from the published per-MW ranges and be explicit about the assumptions. Pick the capacity in MW, choose a range that matches your cooling and redundancy approach, adjust for location, and then add escalation from the data’s date to your construction start. Write down what the number includes. Our guide to cost calculators and location adjustments explains how to do the location and date adjustments without fooling yourself.

Once drawings exist, a range stops being good enough. At that point you need quantities. The breakdown of where the money goes is in data center construction estimating: a cost breakdown, and the equipment lead-time problem that affects both cost and schedule is covered in long-lead equipment and procurement planning. For price movement in the materials side, see the 2026 material cost update.

For general method, the step-by-step guide to estimating construction costs and the post on commercial cost estimating budgets and breakdowns apply here as well, with more attention to the mechanical and electrical scopes.

Common questions

What is the average cost to build a data center per MW?

There is no single average worth trusting. The 2026 Cushman and Wakefield guide gives an all-in greenfield range of $8.9M to $23.3M per MW for the U.S. and Canada, excluding chips and GPUs. Where your project falls depends on design and location.

Is cost per square foot useful for data centers?

Only for rough comparisons between similar facilities. Power density changes the cost so much that two halls of the same size can have very different budgets.

Do these figures include the servers?

No. The figures cited here exclude chips and GPUs, and Census spending data does not count servers and racks.

When you need quantities, not ranges

A range helps you decide whether to pursue a project. Bidding needs measured quantities. If you are pricing the mechanical, electrical or plumbing scope of a facility like this, our MEP estimation team can take it off from your drawings, and our cost estimation service covers the full estimate.
