Use the fields below to estimate direct loss, operational pressure, compliance exposure, and recovery priority for a service outage.
Example data table
| Service | Downtime | Total direct loss | Weighted score | Priority |
|---|---|---|---|---|
| Payment API | 6 hours | $108,720.00 | 80.60 | Priority 2 |
| Identity Platform | 3 hours | $41,900.00 | 68.15 | Priority 3 |
| Data Warehouse | 10 hours | $186,400.00 | 92.40 | Priority 1 |
Use this sample structure to benchmark multiple services and compare restoration order across platforms, applications, and supporting vendors.
Formula used
- Revenue loss = Revenue per hour × Downtime hours.
- Idle staff loss = Idle staff × Idle cost per hour × Downtime hours.
- User productivity loss = Affected users × Productivity cost per hour × Downtime hours.
- SLA penalty loss = SLA penalty per hour × Downtime hours.
- Data loss cost = Records lost × Cost per record.
- Total direct loss = Revenue loss + Staff loss + Productivity loss + SLA loss + Data loss + Recovery cost + Vendor fallback cost.
- Financial score compares total direct loss with the maximum tolerable financial exposure over the MTD window.
- Operational score blends dependency, customer, reputation, and data criticality with time pressure from downtime, RTO, and MTD.
- Compliance score uses compliance severity and adds pressure when downtime approaches or exceeds recovery thresholds.
- Weighted BIA score = Financial score × Financial weight + Operational score × Operational weight + Compliance score × Compliance weight.
How to use this calculator
- Enter the service name and business unit being reviewed.
- Provide outage duration, hourly revenue exposure, staff idleness, and user productivity assumptions.
- Add one-time costs such as recovery spending, fallback vendor charges, and data loss expense.
- Score dependency, customer, compliance, reputation, and data criticality from 1 to 5.
- Enter the target RTO and the maximum tolerable downtime.
- Adjust the financial, operational, and compliance weights to match your organization’s decision model.
- Press the calculate button to see direct loss, score breakdown, and recovery priority above the form.
- Download the result as CSV or PDF for incident reviews, resilience workshops, or continuity documentation.
Frequently asked questions
1. What does this calculator measure?
It estimates outage cost, time-pressure severity, dependency exposure, and recovery priority for a technology service. It helps teams rank which systems deserve the fastest restoration effort.
2. Why are RTO and MTD both included?
RTO shows the preferred recovery target. MTD shows the outer survival limit. Using both highlights whether an outage is merely delayed or already beyond acceptable business tolerance.
3. What is the difference between direct loss and weighted score?
Direct loss is the estimated financial cost. The weighted score adds operational and compliance severity, so recovery decisions are not driven by money alone.
4. How should I set the category weights?
Use higher financial weight for revenue-driven services, higher operational weight for dependency-heavy platforms, and higher compliance weight where legal or audit exposure is significant.
5. What do the priority levels mean?
Priority 1 means immediate restoration. Priority 2 means urgent recovery within the current operational cycle. Priority 3 is controlled recovery. Priority 4 is lower urgency.
6. Can I use this for comparing several systems?
Yes. Run the calculator for each service, save the exports, and compare total loss, score, and priority to build a practical recovery sequence.
7. How often should a business impact analysis be reviewed?
Review it whenever architecture, vendors, data sensitivity, revenue flows, or customer commitments change. Many teams refresh critical service assessments at least quarterly.
8. Does this replace a full continuity plan?
No. It supports continuity planning by quantifying impact and priority. You still need recovery procedures, communication plans, ownership, testing, and governance.
