How much does IT downtime cost you? Work it out in five minutes.

Ten fields and a result in three scenarios. We only count what you can defend in front of the board: lost margin and real additional costs, with staff time shown separately.

Your details
people
Only those whose work genuinely depends on the failed system.
h
The shortest realistic outcome.
h
The most likely outcome.
h
Pessimistic, but realistic.
%
100% means a complete stop. If a workaround exists, enter less.
PLN/h
Gross pay plus contributions and on-costs, divided by working hours. Not take-home pay.
PLN/h
Annual revenue divided by operating hours per year.
%
Revenue minus variable costs, divided by revenue.
%
The rest is deferred sales, which is not a loss of margin.
PLN
External support, overtime, replacement equipment, penalties already incurred.

Impact on profit
Value of idle staff time

The value of staff time is an operational measure. We don't add it to the profit impact, because you pay salaries anyway. The result is deliberately conservative.

What this result doesn't include yet.

The quick mode deliberately underestimates. If the figure already looks significant, the full calculator will show how much bigger the picture is.

  • how the outage unfolds in phases: partial degradation, workarounds and catching up
  • data loss and re-entry
  • cost of technical recovery and replacement equipment
  • contractual penalties, compensation and refunds to customers
  • impact of a cyber incident and obligations after a data breach
  • annual risk exposure and the return on safeguards

Full calculator in Excel, free of charge.

Seventeen sheets: processes, systems and dependencies, failure scenarios, data and recovery, risk and the return on safeguards, plus a one-page report for the management board. It also works in Google Sheets.

  • no macros and no internet connections
  • no sign-up, no email required
  • result as a range, not a single number

Questions about the calculator.

Why is the result three numbers and not one?

Because the length of an outage isn't known in advance. The low, base and high scenarios show a range. Base your decisions about safeguards on the base scenario and check whether the high one is acceptable.

Why don't you add salaries to the loss?

Because you pay salaries regardless of the failure. We show the value of people's unused time separately as an operational measure. Adding it to the lost margin would count the same cost twice.

Does the data I enter go anywhere?

No. The calculator runs in your browser and doesn't send anything. The Excel file has no macros or internet connections either.

What if the result is high?

It's a sign to check what would shorten downtime: monitoring, backups with restore testing, a backup internet connection or a shorter response time in your contract. That's where we start in the free IT review.
