How it works

Estimated revenue = hourly revenue × minutes/60 × affected percentage/100. No currency conversion is applied.

Assumptions and limitations

This is a scenario estimate, not observed loss or a financial forecast. Hourly revenue is 0–10¹², duration 0–525,600 minutes, affected percentage 0–100. Recovery costs, margin, seasonality and deferred purchases are excluded.

How to use this tool

Enter hourly revenue in your own currency, outage minutes and the affected percentage. Calculate the revenue estimate. Select a duration unit and use the percentage slider or exact value. The currency selector formats your entered currency; it does not convert exchange rates. Durations remain capped at 365 days.

Worked example
