Data Breach Cost Estimator
The average cost of a data breach reached $4.88 million globally in 2024 (IBM Cost of a Data Breach Report). But the actual cost to your organisation depends on factors including the number of records compromised, your industry, the speed of detection and containment, and whether you have cyber insurance. This estimator uses industry benchmarks to model the likely financial impact across key cost categories — from notification and response costs to regulatory fines and reputational damage.

Frequently Asked Questions
What are the main cost categories in a data breach?
Breach costs typically fall into four categories: detection and escalation (forensics, investigation), notification (legal, communications, credit monitoring for affected individuals), post-breach response (help desks, legal fees, regulatory response), and lost business (customer churn, reputational damage, downtime).
Which industries face the highest breach costs?
Healthcare consistently records the highest average breach costs, followed by financial services and pharmaceuticals. These sectors hold sensitive data, face strict regulation, and suffer significant reputational damage. The IBM 2024 report placed healthcare average breach costs at over $9 million.
How does cyber insurance affect breach costs?
Cyber insurance can significantly reduce out-of-pocket costs for breach response, regulatory fines (where insurable), business interruption, and third-party liability. However, policies vary widely — coverage limits, exclusions, and incident response support quality all differ significantly between insurers.
What is the average time to identify and contain a breach?
The IBM 2024 report found the average breach lifecycle was 258 days (time to identify plus time to contain). Breaches contained in under 200 days cost on average $1.1 million less than those that took longer — making detection speed a key cost driver.
Can a data breach result in criminal prosecution?
In the UK, the ICO can refer cases to the Crown Prosecution Service for prosecution under the Data Protection Act 2018 and Computer Misuse Act. Directors and senior individuals can face personal liability. GDPR fines themselves are civil, not criminal, but the associated investigations can trigger criminal inquiries.
