Assumptions

  • Inputs are user-entered and processed locally in the browser.
  • The calculator uses transparent deterministic formulas rather than vendor-specific risk, compliance, or availability models.
  • Validate outputs against local policy, contracts, audit evidence, clinical safety requirements, and compliance obligations before taking action.

About this Disaster Recovery Readiness Calculator

Disaster recovery readiness depends on tested recovery, clear ownership, current runbooks, reliable backups, and known dependencies.

Who this calculator is for

  • Healthcare IT, clinical engineering, security, privacy, and compliance teams doing first-pass planning.
  • Hospital and clinic leaders comparing resilience, downtime, backup, and device-maintenance scenarios.
  • Analysts documenting transparent assumptions for business continuity, audit preparation, or risk review.

When to use it

  • Create a transparent first-pass DR readiness score.
  • Compare current readiness with a local target.
  • Identify whether testing, documentation, backup reliability, or ownership is the limiting factor.

How to use this calculator

  1. Enter values from your own system inventory, uptime reports, restore tests, incident logs, device records, contracts, and policy targets.
  2. Replace defaults with local assumptions, prices, and thresholds before relying on the result.
  3. Review the primary output, then use supporting outputs to identify the main operational driver.

Key assumptions

  • Inputs are user-entered and processed locally in the browser.
  • The calculator uses transparent deterministic formulas rather than vendor-specific risk, compliance, or availability models.
  • Validate outputs against local policy, contracts, audit evidence, clinical safety requirements, and compliance obligations before taking action.

How this calculator works

Readiness score is a weighted average of restore test pass rate, runbook coverage, backup success, dependency mapping, owner coverage, and tabletop recency.
Readiness score = weighted average of restore tests 25%, runbooks 20%, backup success 20%, dependencies 15%, owner assignment 10%, and exercise recency 10%.

Inputs explained

Evidence percentages

User-entered percentages for restore testing, runbooks, backup success, dependency mapping, and owner assignment.

Exercise recency

Days since the last tabletop or recovery exercise, scored against a local recency target.

Readiness target

Local target score for planning, governance, or remediation tracking.

Understanding your results

The readiness score is directional. Low component scores should trigger evidence review and remediation planning. Results are planning estimates, not medical, legal, regulatory, security, privacy, procurement, or compliance advice.

Example scenarios

Practical planning example

A service with strong backup success but weak dependency mapping can still show a moderate readiness score and a clear remediation priority.

Key Features

  • Instant Calculation
  • Private & Secure
  • Mobile Optimized

Tips & Best Practices

  • Use the same measurement period across related inputs.
  • Run separate scenarios for critical systems, high-acuity departments, and nonproduction services when requirements differ.
  • Pair the numeric output with documented ownership, evidence, tabletop exercises, restore tests, and exception approvals.

Frequently Asked Questions

Are the weights regulatory requirements?
No. They are simple planning weights for a transparent score. Adjust interpretation to your governance model and compliance obligations.
Can a high score guarantee recovery?
No. It indicates stronger preparation, but actual recovery depends on tested procedures, people, dependencies, incident conditions, and clinical operations.
Are healthcare IT details stored?
No. Calculations run locally in your browser and do not upload, store, or transmit the values you enter.
Can this prove compliance?
No. These calculators are planning tools. Validate assumptions, records, controls, and obligations with security, legal, compliance, clinical engineering, and operational leadership.
Why are assumptions and prices user-entered?
Healthcare IT costs, SLA terms, restore speeds, device risk, clinical impact, and compliance obligations vary by organization. User-entered assumptions keep the result transparent and auditable.
