Calculator
Equipment Downtime Cost Calculator
Estimate downtime cost from unavailable hours, revenue or service impact, lost procedures, margin, and overtime/service premium.
Calculator Inputs
Legend
Equipment Downtime Cost Calculator guidance
Downtime cost = downtime hours x hourly impact + lost procedures x contribution per procedure + emergency service premium.
Input meaning
- Downtime: enter the measured, quoted, or hospital-approved value in hours.
- Hourly service/revenue impact: enter the measured, quoted, or hospital-approved value.
- Lost procedures: enter the measured, quoted, or hospital-approved value.
- Contribution per procedure: enter the measured, quoted, or hospital-approved value.
- Emergency service/overtime premium: enter the measured, quoted, or hospital-approved value.
Result interpretation
- Use the result as a planning estimate, not as a final approval by itself.
- Record the assumptions used so Procurement, Biomedical, Facilities, Finance, and vendors can review the same basis.
Assumptions
- Use hospital finance-approved assumptions for revenue, contribution margin, and patient diversion impact.
- Clinical risk and patient safety impact are not fully captured by cost alone.
Biomedical use
- Use this calculator during RFQ preparation, technical evaluation, acceptance planning, service review, or biomedical workload planning.
How to identify the required values
Use these examples and common working ranges to choose values from gauges, labels, manuals, datasheets, RFQs, service reports, CMMS records, or hospital planning assumptions.
| Field | Example value | Common range | Tip |
|---|---|---|---|
| Downtime | Example: 24 hours. | Use actual downtime from service logs when available; otherwise model 4, 8, 24, and 72 hour scenarios. | Use actual outage duration or model a clear scenario. |
| Hourly service/revenue impact | Example: 500. | Use hospital finance estimates for lost service capacity or outsourced replacement cost. | Use the hospital finance value for lost service capacity. |
| Lost procedures | Example: 6. | Use the number of cancelled, delayed, or outsourced cases caused by the downtime. | Count only procedures directly affected by the downtime. |
| Contribution per procedure | Example: 300. | Use contribution margin, not gross billing, if finance provides it. | Use contribution margin if finance provides it. |
| Emergency service/overtime premium | Example: 0. | Include emergency visit charges, overtime, express parts, and temporary rental costs. | Include urgent service, overtime, courier, rental, or express parts. |
Common ranges are starting points for hospital planning. For final procurement, acceptance testing, electrical design, medical gas design, radiation shielding, dialysis water systems, or clinical use, replace the example values with site-specific data and vendor-confirmed figures.
Input Checklist
Confirm these values before relying on the output for procurement, PM, or service planning.
- Downtime hours
- Hourly impact
- Lost procedures
- Contribution per procedure
- Service premium
Safety And Engineering Notes
Use calculator outputs as planning estimates and verify critical systems with calibrated measurement or qualified engineering review.
- Use hospital finance-approved assumptions for revenue, contribution margin, and patient diversion impact.
- Clinical risk and patient safety impact are not fully captured by cost alone.

Medical Equipment Total Cost of Ownership (TCO) Guide: A Hospital Procurement and Biomedical Engineering Perspective
Many hospitals make procurement decisions based primarily on purchase price. However, the lowest-priced medical equipment is not always the most economical option over its operational life. Hidden costs such as consumables, service contracts, software licenses, spare parts, training, downtime, and equipment upgrades can significantly increase the true cost of ownership.

Medical Equipment Service Contract SLA Guide
A medical equipment Service Level Agreement (SLA) is far more than a maintenance contract. It is a formal document that defines vendor responsibilities, response times, preventive maintenance requirements, spare parts support, reporting obligations, and performance expectations throughout the equipment lifecycle.

Medical Equipment Warranty Review Guide: How Hospitals Should Evaluate Warranty Coverage Before Purchase
Medical equipment warranty evaluation is one of the most overlooked aspects of hospital procurement. Many healthcare organizations focus heavily on technical specifications and purchase price while paying little attention to warranty terms, exclusions, service commitments, and component coverage.
