What this calculator estimates
Estimate labor, revenue and recovery cost from ransomware downtime.
How to use it
Enter Employees unable to work; Downtime hours; Average burdened hourly labor cost ($); Lost contribution margin per downtime hour ($); Incident response and recovery cost ($); Expected insurance reimbursement ($). Select Calculate to update the results.
How the calculation works
Employee idle time, lost contribution margin and recovery costs are totaled, then expected insurance reimbursement is applied.
Worked example: starting scenario
| Employees unable to work | 250 |
|---|---|
| Downtime hours | 48 |
| Average burdened hourly labor cost ($) | 55 |
| Lost contribution margin per downtime hour ($) | 18000 |
| Incident response and recovery cost ($) | 450000 |
| Expected insurance reimbursement ($) | 500000 |
| Estimated net ransomware cost | $1,474,000.00 |
|---|---|
| Gross downtime and recovery cost | $1,974,000.00 |
| Employee idle-time cost | $660,000.00 |
| Insurance reimbursement | $500,000.00 |
Important limitations
Double counting, partial operations, ransom decisions, legal restrictions and policy coverage require case-specific analysis.
Avoid counting the same lost activity twice
Use the outage duration and hourly business impact for one consistent operating schedule. Response, restoration and external professional costs should be additional to that lost activity. A payment demand is not a recovery guarantee, and the model does not estimate the chance of recovery or include losses that have not been entered.
