Interactive calculator

Model the downtime cost of a ransomware event against your own numbers.

Five inputs. A defensible range, not a false-precision point estimate. Every day-band below traces to a claim already published on this site — no invented industry multipliers.

Calculator

Direct downtime cost, ransom-demand exposure (dental), and the two controls that change the range.

Revenue per business day ($)Anchor: a single-doctor practice typically produces $5,000–$15,000 in collected production per day (source).Dentists on staffUsed for sizing context only. Not multiplied into the cost figure.

Have your backups been restore-tested in the last 90 days?

Yes — testedNo — or not sure

Do you carry cyber liability insurance?

YesNoNot sure

Fill in revenue per business day, whether backups are restore-tested, and whether cyber insurance is in place to see the range.

How these numbers are sourced

Dental recovery band 5–21 days — Dental ransomware playbook and /industries/dental.
Dental daily production $5,000–$15,000 — Dental ransomware playbook.
Dental ransom-demand band $50,000–$250,000 — Dental industry page.
Law-firm recovery band 7–21 days — Law-firm ransomware playbook and /industries/law-firms.
CPA recovery band 5–21 days prepared, or 4–8 weeks (28–56 days) during tax season without tested backups — Tax-season ransomware playbook and /industries/accounting.
Recovery-cost qualitative block — Cyber Insurance for First-Time SMB Buyers. No forensic / counsel / notification multiplier is invented, because no defensible published band exists.
FBI IC3 caveat — reported IC3 losses explicitly exclude downtime and remediation, so IC3 data is not used as a formula anchor here (see the first-24-hours article).
