OT Risk Mitigation Payback Calculator

Use this calculator to estimate financial payback for an OT cybersecurity risk mitigation project. It helps turn downtime exposure, compliance improvement, response savings, and recovery resilience into a planning level business case.

What this calculator does

  • Estimate payback for an OT risk mitigation project using investment, annual risk reduction savings, and support cost.
  • Use it to compare mitigation options such as monitoring, segmentation, backup recovery, asset inventory, or access control improvements.
  • The result estimates payback for an OT cyber risk reduction project.

Formula used

  • Net annual OT mitigation savings = annual OT risk reduction savings - annual mitigation support cost
  • OT risk mitigation payback period = OT mitigation investment รท net annual savings

Inputs explained

  • OT mitigation investment: Include technology, engineering, integration, testing, change windows, documentation, training, and project management.
  • Annual OT risk reduction savings: Use expected savings from avoided downtime, faster recovery, reduced response cost, audit remediation, insurance improvement, or productivity gains.
  • Annual mitigation support cost: Include licenses, monitoring, rule review, maintenance, spares, training, managed services, and governance effort.

How to use the result

  • Use it to compare projects and communicate why a mitigation deserves funding.
  • It depends on defensible savings assumptions and should be paired with risk and operations review.

Common questions

  • What is the OT risk mitigation payback calculator for? It estimates payback for a defensive OT security mitigation investment.
  • What information should I enter? Use investment, annual risk reduction savings, and annual support cost.
  • What does the result tell me? The result helps compare mitigation options using a common financial view.
  • When is the result only an estimate? It is only an estimate when risk exposure, support cost, implementation scope, or savings assumptions change.
