What this calculator estimates

Estimate direct breach-response, record, downtime and uninsured costs. It runs locally in the browser and is intended for planning and comparison.

How to use it

Enter the requested values, select Calculate, review the headline result and supporting figures, then change one input at a time to compare scenarios.

How the calculation works

Affected-record cost, downtime loss and response expenses are totaled, then expected insurance recovery is subtracted.

Input checklist

The Cyber Breach Cost Calculator uses the values shown in its form. Before calculating, check each input independently so an incorrect unit or time period does not carry through to the final result.

• Affected records: verify that this value uses the unit, period, and definition shown by the calculator.
• Estimated cost per affected record ($): verify that this value uses the unit, period, and definition shown by the calculator.
• Downtime hours: verify that this value uses the unit, period, and definition shown by the calculator.
• Revenue or contribution margin lost per hour ($): verify that this value uses the unit, period, and definition shown by the calculator.
• Forensics, legal, notification and PR cost ($): verify that this value uses the unit, period, and definition shown by the calculator.
• Expected cyber-insurance reimbursement ($): verify that this value uses the unit, period, and definition shown by the calculator.

Practical interpretation

Use the Cyber Breach Cost Calculator result as the answer to the specific inputs entered, not as a universal value. The calculation currently described on this page is: Affected-record cost, downtime loss and response expenses are totaled, then expected insurance recovery is subtracted. Change one important input at a time when comparing scenarios so you can see which assumption actually drives the difference.

Checks before relying on the result

Actual project prices vary with location, labor rates, material grade, site conditions, permits, waste, contractor pricing, and scope changes. Recalculate when a key value changes, and keep the original inputs with the result if you need to reproduce or compare the calculation later.

Important limitations

Fines, litigation, business interruption, policy exclusions and reputational loss may differ substantially.
