Identity Access Downtime Cost Estimator

This estimator measures the operational cost of an identity and access outage, such as an authentication failure, directory disruption, or authorization misconfiguration. It adds lost revenue, idle labor, and extra response costs across the outage period.

The result can support resilience planning for identity providers, directory services, single sign-on, and access gateways. It is most accurate when the affected employee count and hourly revenue reflect only the processes that are actually blocked.

Extra costs

1. Estimate outage duration
Enter the number of hours the affected process is unavailable or materially degraded.

2. Enter hourly business loss
Use lost revenue or contribution associated with the blocked process.

3. Count affected employees
Include only people who cannot perform productive alternate work.

4. Set loaded labor cost
Enter wages plus relevant employer costs per employee-hour.

5. Add exceptional costs
Include response, vendor, communications, workaround, and recovery expenses not captured elsewhere.

6. Review the components
Use the breakdown to see whether business loss, labor, or extra costs drive the estimate.

Lost revenue = Downtime hours × Revenue lost per hour Idle labor = Downtime hours × Affected employees × Labor cost per hour Total downtime cost = Lost revenue + Idle labor + Extra costs

Use contribution margin rather than gross revenue when that better reflects the economic loss. Extra costs may include emergency support, communications, temporary services, or recovery fees.

What the result means

The displayed value is a scenario estimate for an identity or access outage. Use it to compare assumptions and priorities rather than as a guaranteed outcome.

Some users may retain access through cached sessions or offline workflows; reduce the affected population when those alternatives are realistic.

Given: 4 downtime hours, $18,000 lost per hour, 320 affected employees at $48 per hour, and $12,000 extra costs.

Calculation: Lost revenue = 4 × $18,000 = $72,000. Idle labor = 4 × 320 × $48 = $61,440. Total = $72,000 + $61,440 + $12,000 = $145,440.

Result: The estimated downtime cost is $145,440.

Should I use revenue or profit per hour?

Use the amount that best represents economic loss. Contribution margin is often more appropriate than gross revenue when variable costs are avoided during downtime.

How do I handle partial degradation?

Reduce the hourly loss and affected employee count to reflect the portion of work that remains available.

Should overtime after recovery be included?

Add it to extra costs when it is directly caused by clearing the backlog or completing recovery work.

Can I include customer compensation?

Yes. Credits, refunds, penalties, or service-level payments can be entered as extra costs.

Does this include long-term reputational impact?

No. The calculator focuses on immediate downtime costs. Model longer-term customer or regulatory effects separately when material.
