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.

Sensitivity preview

Target RTO -10%: Largest Gap 50.00%

Target RTO Current: Largest Gap 50.00%

Target RTO +10%: Largest Gap 50.00%

Formula: RTO gap = actual RTO - target RTO. RPO gap = actual RPO - target RPO. Largest gap percent = max(positive RTO gap / target RTO, positive RPO gap / target RPO) x 100.

About this RTO/RPO Gap Calculator

RTO and RPO gaps show where tested recovery time or data-loss exposure exceeds the target accepted by the organization.

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

  • Compare tested recovery time with RTO target.
  • Compare actual backup or replication exposure with RPO target.
  • Create a simple gap percentage for prioritizing recovery work.

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

RTO gap = actual RTO minus target RTO. RPO gap = actual RPO minus target RPO. Largest gap percent compares each positive gap against its target and returns the larger percentage.
RTO gap = actual RTO - target RTO. RPO gap = actual RPO - target RPO. Largest gap percent = max(positive RTO gap / target RTO, positive RPO gap / target RPO) x 100.

Inputs explained

RTO target and actual

Maximum acceptable recovery time and the actual or tested recovery time.

RPO target and actual

Maximum acceptable data-loss window and the actual or tested restore point age.

System count

Number of systems represented by the scenario for planning context.

Understanding your results

A zero largest gap percent means both objectives are within the entered targets. Positive values show the largest miss relative to its target. Results are planning estimates, not medical, legal, regulatory, security, privacy, procurement, or compliance advice.

Example scenarios

Practical planning example

A 4-hour RTO target with a 5-hour tested restore has a 1-hour RTO gap and a 25% RTO miss before reviewing RPO.

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

What does a negative gap mean?
A negative raw gap means the actual value is better than the target. The largest gap percent only counts misses above target.
Should RTO and RPO be measured per system?
Often yes. Group systems only when they share the same recovery tier, dependencies, owners, and clinical or business impact.
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.
