Bed turnover calculator
Occupancy tells you how full your beds were. It does not tell you how many patients they served, or how long each bed stood empty waiting for the next one — and two hospitals at the same 80% occupancy can differ enormously on both. This works out bed turnover rate and turnover interval from the same four figures you already collect for occupancy.
Turnover rate counts patients per bed. Turnover interval measures the idle gap between them. Read together with occupancy and length of stay, they explain almost everything about how an inpatient ward is actually running.

Reading it
What the two numbers mean together
Turnover rate is how many patients one bed served in the period. A 60-bed hospital with 540 discharges in a quarter ran 9 patients through each bed. On its own it says little — a high rate can mean efficient flow or it can mean stays are too short.
Turnover interval is the more actionable of the two: the average number of days a bed sat empty between one patient leaving and the next arriving. It is where discharge process, housekeeping and admission scheduling all show up in a single number.
- Negative — beds are being re-filled the same day a patient leaves. Not efficiency; usually a bed shortage, and worth reading alongside any admissions you turned away.
- Around 0–1 day — tight. Normal for a busy hospital, with little slack for deep cleaning or a delayed discharge.
- 1–3 days — comfortable for most small and mid-sized hospitals.
- Above 3 days — beds are idle. The cause is more often admission scheduling or slow discharge paperwork than genuinely absent demand.
The bands above are interpretive, not a standard. No Indian authority publishes a target turnover interval for small hospitals, and we did not find one — so treat them as a way to read your own trend, not a grade.
Formula
A note on the turnover-rate formula
Some sources multiply turnover rate by 100 and present it as a percentage. That is not standard, and it is not a percentage of anything — a bed that served nine patients in a quarter is 9, not 900%. This calculator uses the plain ratio: discharges ÷ available beds, giving patients per bed.
Discharges should include deaths and transfers out — every episode that freed the bed. Counting only routine discharges understates turnover and inflates the interval, and the effect is largest in exactly the wards where it matters most.
