IT Downtime Calculator
Even a short IT outage can have a serious impact on a business. Lost productivity, missed customer interactions and interrupted operations quickly add up. For many organisations, a single hour of downtime can translate into thousands of pounds in lost value.
This calculator helps you estimate the real cost of an IT outage in your organisation by combining lost employee productivity, revenue disruption and recovery costs. However, note that it does not account for any reputational damage or regulatory fines that may come as a result of service outage.
To estimate the potential cost of downtime, you only need to provide a few simple figures about your organisation. These inputs help calculate the combined impact of operational disruption and lost productivity.
- Number of employees affected – how many people are unable to work during the outage.
- Average hourly cost per employee – the approximate cost of an employee per hour, including salary and overhead.
- Downtime duration – the length of the outage in hours.
- Estimated lost revenue per hour – any sales, transactions or billable work that cannot occur while systems are unavailable.
- Recovery or external costs – any additional expenses required to restore services, such as consultants or emergency support.
The calculator then combines these figures to produce an estimated total cost for the downtime:
