Calculator
Biomedical Staffing Calculator
Estimate biomedical engineering FTE need from preventive maintenance, corrective maintenance, project, and administrative workload.
Calculator Inputs
Legend
Biomedical Staffing Calculator guidance
Required FTE = total annual workload hours / productive annual hours per FTE.
Input meaning
- Annual PM hours: enter the measured, quoted, or hospital-approved value.
- Annual corrective maintenance hours: enter the measured, quoted, or hospital-approved value.
- Annual project/support hours: enter the measured, quoted, or hospital-approved value.
- Admin and coordination load: enter the measured, quoted, or hospital-approved value in %.
- Productive hours per FTE/year: 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
- Staffing also depends on risk class, workshop maturity, outsourcing scope, shift coverage, and service response expectations.
- Use this as a workload estimate, not a staffing policy by itself.
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 |
|---|---|---|---|
| Annual PM hours | Example: 1200. | Estimate from the PM schedule; large hospitals may have hundreds to thousands of PM hours per year. | Use PM schedule or CMMS history rather than guessing. |
| Annual corrective maintenance hours | Example: 900. | Use CMMS history when available; otherwise estimate from call volume and average repair time. | Use corrective work-order history when available. |
| Annual project/support hours | Example: 300. | Include installations, acceptance testing, tenders, training, and user support. | Include tender, installation, testing, and user-support work. |
| Admin and coordination load | Example: 20 %. | 10-30% is common for documentation, coordination, meetings, and reporting. | Include documentation, coordination, and reporting time. |
| Productive hours per FTE/year | Example: 1500. | Common productive planning range is 1,400-1,700 hours per FTE per year after leave and admin. | Use productive hours after leave, training, and non-workshop duties. |
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.
- PM hours
- Corrective maintenance hours
- Project hours
- Admin percentage
- Productive hours per FTE
Safety And Engineering Notes
Use calculator outputs as planning estimates and verify critical systems with calibrated measurement or qualified engineering review.
- Staffing also depends on risk class, workshop maturity, outsourcing scope, shift coverage, and service response expectations.
- Use this as a workload estimate, not a staffing policy by itself.
