How the result is calculated

The calculator uses four components:

  • Productivity: employees × hourly cost × idle share
  • Lost revenue: monthly revenue × affected share of sales ÷ working hours
  • Recovery and indirect impact: a percentage added on top, based on your business
  • Annual cost: cost per hour × expected hours of downtime

The result is an order of magnitude, not an exact figure. The goal is one number management and IT agree on, which you can then weigh against the cost of better uptime.
