What Does an EMI Survey Cost?

The cost of an EMI survey can vary widely depending on several key factors, but I can give you some general ranges in an outline form to help set expectations.

Here’s a breakdown:

Typical EMI Survey Cost Range (U.S.)

  • Small site or facility (single room, lab, small office):
    → $2,000–$5,000 per survey

  • Medium site (entire floor, small industrial facility, data center section):
    → $5,000–$15,000

  • Large or complex site (hospital, full industrial plant, large data center, military installation):
    → $15,000–$50,000+

Cost Factors

The final price depends on:

  1. Scope of the survey: How much area, how many measurement points, and how many types of equipment are being surveyed.

  2. Duration: One-day survey vs. multi-day or long-term monitoring.

  3. Special requirements: Specialized equipment (high-frequency surveys, shielding assessments, etc.).

  4. Location: Travel costs if the survey team needs to come from another city or state.

  5. Reporting depth: A simple pass/fail report is cheaper than a complete technical analysis with mitigation recommendations.

What’s Typically Included

  1. Site visit and measurement campaign.

  2. Use of calibrated measurement equipment.

  3. Basic data analysis.

  4. Written report summarizing findings, often including maps or diagrams.

Additional costs may apply if you need:

  1. In-depth root-cause analysis (this leans into EMI investigation work)

  2. Detailed mitigation plans or engineering redesign support

  3. Compliance certification testing
