Calculator Inputs
Formula Used
The calculator combines identity assurance, operational exposure, and control coverage into one weighted score. It then estimates review time, recommended validity, and confidence.
Risk Score = Base Visitor Risk + Asset Risk + Area Risk
+ Duration Risk + Zone Risk + Incident Risk
+ Missing Document Penalty + After Hours Penalty
+ Unverified Identity Penalty + No Escort Penalty
+ New Visitor Penalty - Verified Control Credits
Approval Time adds visitor handling time, risk-driven review effort, after-hours overhead, and zone complexity.
Pass Validity starts from visit duration, then shortens as risk increases to limit unnecessary exposure.
How to Use This Calculator
- Enter the request, visitor, and host details.
- Select the visitor type, asset sensitivity, and access area.
- Set visit duration, number of zones, and prior incident count.
- Mark completed checks, identity status, escort need, and timing.
- Submit the form to view approval guidance above the form.
- Use CSV or PDF export for records, reviews, or audit packs.

Frequently Asked Questions
1. What does the risk score represent?
It summarizes entry exposure using visitor type, area sensitivity, timing, incident history, and control checks. Higher scores need stronger review or tighter restrictions.
2. Why does identity verification reduce risk?
Verified identity lowers uncertainty. Security staff can match the person, documents, and request details before physical access is granted.
3. How is approval time estimated?
The model adds base handling time, risk-driven review time, zone complexity, and after-hours overhead. Better documents reduce approval delay.
4. When should I require an escort?
Use escorts for high-risk visitors, unfamiliar contractors, sensitive assets, or restricted areas. Escorts create oversight and reduce unsupervised movement.
5. Why does pass validity shrink as risk rises?
Shorter validity limits exposure if access needs change, approval conditions are missed, or a visit runs longer than expected.
6. Can this support audit documentation?
Yes. The result section and exports help retain evidence for reviews, visitor logs, exception tracking, and checkpoint accountability.
7. Is this calculator a replacement for policy?
No. It supports policy execution. Final approval should still follow site procedures, security standards, and legal or contractual requirements.
