Formula Used

One-Time Setup Cost = Facility Buildout + Server Hardware + Network/Security Equipment + Software/Licenses + Migration/Implementation

Monthly Recurring Cost = Replication + Bandwidth + Staffing + Vendor Contract + Cloud Storage + Monitoring

Annual Recurring Cost = Monthly Recurring Cost × 12

Annual Testing Cost = Tests Per Year × Cost Per Test

Annual Training Cost = Training Sessions Per Year × Cost Per Training Session

Annual Downtime Exposure = Downtime Hours Per Activation × Downtime Cost Per Hour × Activation Risk

First-Year Total = (One-Time Setup + Annual Recurring + Annual Testing + Annual Training + Annual Downtime Exposure) + Contingency

Contingency = Year 1 Base × Contingency Percentage

Multi-Year TCO = Sum of yearly operational cost adjusted by inflation, with one-time setup added in year one and contingency applied annually

Cost per Protected System = First-Year Total ÷ Protected Systems

Cost per Recovery Seat = First-Year Total ÷ Recovery Seats

How to Use This Calculator

  1. Enter all one-time build and deployment costs for your hot site.
  2. Fill monthly recurring items such as replication, staffing, bandwidth, storage, vendor support, and monitoring.
  3. Add operational assumptions for tests, training, downtime impact, risk percentage, contingency, and inflation.
  4. Include the number of protected systems and recovery seats for unit-cost analysis.
  5. Click the calculate button to show the result under the header and above the form.
  6. Use the CSV and PDF buttons to export the result summary and input snapshot.

FAQs

1. What is a hot site?

A hot site is a ready-to-run recovery environment with systems, connectivity, and data access prepared for rapid failover during a disruption.

2. Why include downtime exposure?

Downtime exposure estimates the financial effect of disruption when the recovery site is activated. It helps connect resilience planning to business impact.

3. Why does the calculator use activation risk?

Activation risk converts a worst-case downtime event into an expected annual cost. This makes the estimate more practical for budgeting.

4. What belongs in one-time setup cost?

Include facility preparation, racks, hardware, network gear, security appliances, software setup, data migration, and deployment services.

5. What belongs in recurring cost?

Recurring cost usually includes bandwidth, replication services, cloud storage, vendor retainers, staffing, monitoring, and support contracts.

6. Why calculate 3-year and 5-year TCO?

Total cost of ownership highlights long-term spending, not just launch cost. It improves board, audit, and procurement decisions.

7. Should contingency always be added?

Yes, most recovery projects face uncertainty around testing, logistics, licensing, or emergency staffing. A contingency reserve improves planning reliability.

8. Can this calculator support compliance planning?

Yes. The inputs and outputs can support continuity documentation, budget defense, resilience reviews, vendor comparisons, and internal control discussions.
