Downtime Cost Calculator
Estimate revenue and productivity exposure from an availability incident. Use the interactive workspace below to test your assumptions and build a practical decision brief.
Why this calculation matters
A useful calculation does more than produce a number. It makes the assumptions visible, shows how a cautious case differs from an ambitious one, and gives you a repeatable way to revisit the decision. This downtime cost model is built around the inputs that most directly affect the result.
How to use the calculator
- Revenue per hour: Average revenue generated per operating hour.
- Team cost per hour: Loaded cost of affected staff.
- Downtime duration: Incident duration in hours.
Start with current, documented numbers. Then compare the scenario cards. If the conclusion changes dramatically between the conservative and ambitious cases, treat uncertainty itself as an important part of the decision.
How to interpret your result
The headline value is labeled estimated downtime cost. It is a planning result, not a promise. Compare it with your own target, available capacity, cash position, and alternatives.
Formula and assumptions
Formula: (Revenue per hour + team cost per hour) × downtime hours.
- The calculation is a planning estimate, not a guarantee.
- Inputs should use consistent definitions and reporting periods.
- Compare a conservative scenario before making a difficult-to-reverse decision.
Limitations and frequently asked questions
Provider prices, workload mix, retries, and quality requirements can change the realized result.
Avoid mixing gross and net values, comparing different time periods, or using an industry benchmark that does not match your geography, customer segment, scale, or business model. A precise-looking result can still be unreliable when the inputs are uncertain.
What does the Downtime Cost Calculator measure?
Estimate revenue and productivity exposure from an availability incident. The result is designed as a planning estimate that should be compared with your own records and a conservative scenario.
Which inputs should I verify first?
Start with revenue per hour and team cost per hour. Use matching periods and definitions so the comparison remains meaningful.
Can I use the result as professional advice?
No. Provider prices, workload mix, retries, and quality requirements can change the realized result. Use the result to structure questions, compare scenarios, and prepare for qualified advice when the decision is material.
How often should I recalculate?
Recalculate whenever a core input changes materially, after receiving a new quote or benchmark, and before making an expensive or difficult-to-reverse commitment.
