About this tool
What the Nurse Staffing Calculator does
Inpatient units plan staffing with nursing hours per patient day (HPPD): the nursing hours each patient needs in 24 hours. Census × HPPD gives total nursing hours, which converts into nurses per shift and full-time equivalent (FTE) positions once leave and non-productive time are allowed for.
Formula
- Nursing hours per day = census × HPPD
- Nurses per shift = daily hours ÷ shifts per day ÷ shift length
- FTEs = daily hours × 365 ÷ (FTE hours × (1 − non-productive time))
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Average daily census | 28 |
| Nursing hours per patient day | 8 |
| Shift length | 12 hours |
| Hours per FTE per year | 2,080 |
| Non-productive time (leave, training) | 12% |
| Required patients per nurse (optional) | 5 |
| Result | Value |
|---|---|
| Nurses per shift (HPPD method) | 9.3 |
| FTEs required | 44.7 |
| Nursing hours per day | 224 |
| Nurses per shift at the ratio | 6 |
How to read the result
Where staffing ratios are mandated, the ratio sets the minimum regardless of HPPD.
Acuity varies by shift and day; skill mix and acuity tools refine these averages.
