The facts show that the average cost of IT systems downtime is close to $5,600 per minute according to the Uptime Institute Symposium.
In the recent study “Calculating the Cost of Data Center Outages” The Ponemon Institute identifies the true bottom-line costs of data center downtime as:
- The average cost of downtime across industries was approximately $5,600 per minute.
- The average reported incident length was 90 minutes, resulting in an average cost per incident of approximately $505,500.
- For a total data center outage, which had an average recovery time of 134 minutes, average costs were approximately $680,000.
- For a partial data center outage, which averaged 59 minutes in length, average costs were approximately $258,000.
- The report cited the highest cost of a single event at about $1 million (more than $11,000 per minute).

How costly is IT downtime in your organization?
A Simple Estimate:
Estimated Average Cost of hour of downtime = Employee Costs per Hour * Fraction Employees Affected by Outage + Average Revenue per Hour * Fraction Revenue Affected by Outage
- Employee Costs per Hour: total salaries and benefits of employees per week divided by the average number of working hours
- Average Revenue per Hour: total revenue per week divided by average number of open hours
- “Fraction Employees Affected by Outage” and “Fraction Revenue Affected by Outage” are just educated guesses or plausible range
- Since evaluating purchases, estimates are ok
- Ignores cost of repair, such as cost of operator overtime or bringing in consultants
- Ignores daily, seasonal variations in revenue
- Indirect costs of outages can be as important as these more immediate
- Hence estimate tends to be conservative side
- Revenue $3.1B/year, with 7744 employees
- Revenue per hour (24×7): ~ $350,000
- If outage affects 90% revenue: ~ $320,000
- Public quarterly reports do not include salaries and benefits directly
- Assume avg. annual salary is $85,000
- $656M / year, or $12.5M / week for all staff
- @ 50 hours / week => ~ $250,000 per hour
- If outage affects 80% employees: $200,000
- Total: ~ $520,000 / hour
